Server Administration

Server administration is to design, install, administer, and optimize company servers and related components to achieve high performance of the various business functions supported by the servers as necessary.

Automatic Virtual Machine Activation acts as a proof-of-purchase tool, allowing to confirm that Windows products are operated in agreement with the Product Use Rights and Microsoft Software License Terms.

AVMA lets you start Windows Server virtual machines on Windows Server Hyper-V host that is correctly activated, even in separate environments. AVMA binds the virtual machine activation to the certified virtualization host and activates the virtual machine when it starts up. Reporting and tracking data is open on the virtualization host.

Practical applications

On virtualization hosts, AVMA offers several benefits.

Server data center administrators can utilize AVMA to do the following:

  • Activate virtual machines in remote locations
  • Activate virtual devices with or without an internet connection
  • Track virtual device usage and permissions from the virtualization host, without requiring any access rights on the virtualized systems

Service Provider License Agreement partners and other hosting providers do not have to share product keys with tenants or access a tenant's virtual machine to start it. Virtual machine activation is transparent to the resident when AVMA is operated. Hosting providers can use the server logs to confirm license submission and to track client usage history.

System requirements

The virtualization host that will run virtual machines ought to be activated. Keys can be acquired through the Volume Licensing Service Center or your OEM provider.

AVMA demands Windows Server Datacenter edition with the Hyper-V host role installed. The working system version of the Hyper-V host chooses which versions of the operating system can be started in a virtual machine. Here are the guests that the different version hosts can start:

How to implement AVMA?

To start VMs with AVMA, you use a generic AVMA key that corresponds to the version of Windows Server that you like to start. To start a VM and start it with an AVMA key, do the following:

  • On the server that will host virtual devices, establish and configure the Microsoft Hyper-V Server role. For more details, see Install Hyper-V Server. Make sure that the server is successfully activated.
  • Create a virtual machine and establish a supported Windows Server working system on it.
  • Once Windows Server is established on the VM, you install the AVMA key in the VM. From PowerShell or an advanced Command Prompt, execute the following command:
slmgr /ipk 

Reporting and tracking

The Key-Value Pair exchange between the virtualization broadcaster and the VM bears real-time quest data for the visitor operating systems, including activation data. This activation data is stored in the Windows registry of the virtual machine. Historical data about AVMA requests are logged in Event Viewer on the virtualization host.

In this blog, we are looking at how to extend Linux disk VMware hyper-v centos/Redhat on the fly live.

Check if you can expand the current disk or require to add a new one.

This is rather a significant step because a disk that has been partitioned into 4 primary divisions already can not be raised anymore. To prevent this, log into your server and run fdisk -l at the command line.

# fdisk -l

Disk /dev/sda: 187.9 GB, 187904819200 bytes
255 heads, 63 sectors/track, 22844 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot     Start       End     Blocks   Id  System
/dev/sda1   *           1       25      200781   83  Linux
/dev/sda2              26       2636    20972857+  8e  Linux LVM

If it examines like that, with only 2 sections, you can safely open the current hard disk in the Virtual Machine.

However, if it displays like this:

~# fdisk -l

Disk /dev/sda: 187.9 GB, 187904819200 bytes
255 heads, 63 sectors/track, 22844 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot     Start       End     Blocks   Id  System
/dev/sda1   *           1       25      200781   83  Linux
/dev/sda2              26       2636    20972857+  8e  Linux LVM
/dev/sda3            2637       19581   136110712+  8e  Linux LVM
/dev/sda4           19582       22844   26210047+  8e  Linux LVM

It will offer you that there are already 4 primary sections on the system, and you ought to count a new Virtual Disk to your Virtual Machine. You can always use that extra Virtual Disk to improve your LVM size, so don’t worry.

The “hardware” part, “physically” adding disk space to your VM

Do that in your VMWare / esx / hyper-v console. If the option is greyed out to expand? Add a new disk or shut down the VM and extend the disk as such.

Partitioning the unallocated area: if you’ve raised the disk size

Once you’ve modified the disk’s size in VMware, bounce up your VM too if you had to shut it down to expand the disk size in vSphere. If you’ve rebooted the server, you won’t have to rescan your SCSI machines as that occurs on boot. If you did not reboot your server, rescan your SCSI systems as such.

First, check the name of your scsi devices.

$ ls /sys/class/scsi_device/
0:0:0:0 1:0:0:0  2:0:0:0

Then rescan the scsi bus. Beneath you can replace the ‘0:0:0:0’ with the actual scsi bus word found with the last command. Each colon is prefixed with a slash, which is what creates it looks weird.

$ echo 1 > /sys/class/scsi_device/0\:0\:0\:0/device/rescan

Partitioning the unallocated space: if you’ve included a new disk

If you’ve included a new disk on the server, the activities are the same to those described above. Either of rescanning an already existing scsi bus like shown earlier, you have to rescan the server to detect the new scsi bus as you’ve included a new disk.

$ ls  /sys/class/scsi_host/
total 0
drwxr-xr-x  3 root root 0 Feb 13 02:55 .
drwxr-xr-x 39 root root 0 Feb 13 02:57 ..
drwxr-xr-x  2 root root 0 Feb 13 02:57 host0

Your host machine is called ‘host0’

$ echo "- - -" > /sys/class/scsi_host/host0/scan

It won’t show any output, but running ‘fdisk -l’ will display the new disk.

Create the new partition

Once the rescan is done, you can identify if the space can be seen on the disk.

~$  fdisk -l

Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot     Start       End     Blocks   Id  System
/dev/sda1   *           1       13      104391   83  Linux
/dev/sda2           14      391     3036285   8e  Linux LVM

So the host can now visualize the 10GB hard disk.

~$  fdisk /dev/sda

The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with:

Command (m for help): n

Now type ‘n’, to build a new partition.

Command action
e   extended
p   primary partition (1-4)

Now select “p” to create a further direct partition.

Partition number (1-4): 3

Select your partition number. Since it already had /dev/sda1 and /dev/sda2, the logical number would be 3.

First cylinder (392-1305, default 392): 
Using default value 392
Last cylinder or +size or +sizeM or +sizeK (392-1305, default 1305): 
Using default value 1305

The cylinder matters will vary depending on your plan. It should be secure to just hint enter, as fdisk will give you a default value for the first and last cylinder.

Command (m for help): t
Partition number (1-4): 3
Hex code (type L to list codes): 8e
Changed system type of partition 3 to 8e (Linux LVM)
Command (m for help): w

Once you get around to the major command within fdisk, type w to report your partitions to the disk. You’ll get a notification about the kernel still utilizing the old partition table, and to reboot to utilize the new table. The reboot is not required as you can even rescan for those partitions using partprobe. Execute the below to scan for the recently created partition.

~$ partprobe -s

If that does not function for you, you can attempt to use “partx” to rescan the machine and add the latest partitions. In the command below, difference /dev/sda to the disk on which you’ve just included a new partition.

~$ partx -v -a /dev/sda

If that even does not offer you the recently completed partition for you to operate, you have to reboot the server.

~$  fdisk -l

Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot     Start       End     Blocks   Id  System
/dev/sda1   *           1       13      104391   83  Linux
/dev/sda2           14      391     3036285   8e  Linux LVM
/dev/sda3           392     1305    7341705   8e  Linux LVM

Extend your Logical Volume with the new partition.

Now, assemble the physical volume as a cause for your LVM. Please return /dev/sda3 with the newly built partition.

~$  pvcreate /dev/sda3
Physical volume "/dev/sda3" successfully created

Now identify how your Volume Group is called.

~$  vgdisplay
--- Volume group ---
VG Name             VolGroup00

Let’s give that Volume Group by including the newly built physical volume to it.

$  vgextend VolGroup00 /dev/sda3
Volume group "VolGroup00" successfully extended
~$  pvscan
PV /dev/sda2   VG VolGroup00   lvm2 [2.88 GB / 0    free]
PV /dev/sda3   VG VolGroup00   lvm2 [7.00 GB / 7.00 GB free]
Total: 2 [9.88 GB] / in use: 2 [9.88 GB] / in no VG: 0 [0   ]

Now we can extend Logical Volume .

~$  lvextend /dev/VolGroup00/LogVol00 /dev/sda3
Extending logical volume LogVol00 to 9.38 GB
Logical volume LogVol00 successfully resized

If you’re executing this on Ubuntu, use the following.

~$  lvextend /dev/mapper/vg-name /dev/sda3

All that remains now, is to resize the file system to the volume group, so we can utilize the space. Substitute the path to the correct /dev device if you’re on ubuntu/debian systems.

~$  resize2fs /dev/VolGroup00/LogVol00
resize2fs 1.39 (29-May-2006)
Filesystem at /dev/VolGroup00/LogVol00 is mounted on /; on-line resizing required
Performing an on-line resize of /dev/VolGroup00/LogVol00 to 2457600 (4k) blocks.
The filesystem on /dev/VolGroup00/LogVol00 is now 2457600 blocks long.
$ resize2fs /dev/mapper/centos_sql01-root
resize2fs 1.42.9 (28-Dec-2013)
resize2fs: Bad magic number in super-block while trying to open /dev/mapper/centos_sql01-root
Couldn't find valid filesystem superblock.

In that case, you’ll require to improve the XFS partition.

~$  df -h
Filesystem          Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00 9.1G 1.8G  6.9G  21% /
/dev/sda1           99M   18M   77M  19% /boot
tmpfs               125M    0  125M   0% /dev/shm

What is Cloudflare?

Cloudflare is a free CDN-type product that protects against threats such as SQL injection and identity theft. Cloudflare also increases site performance and speeds up loading times by using their various data centers that are situated around the world. The Cloudflare network performed like a giant VPN. This means that a site visitor will enable the website by being externally changed to the closest server. What this means is easy:

  • the closer the data center
  • the quicker the website will load for the user
  • This is unique to Cloudflare.

Another advantage is the reduction of bot crawls, which can be both helpful and bad depending on their source. A bot crawl is typically done to go to websites and “crawl” for details on the web page. While these can be so helpful when holding content thieves using the website pattern without any permission, they can also create false ad impressions, inject viruses and malware through file backdoors, stealing website content and messages. A direct way to think about Cloudflare is to inform it as a web proxy. Because a cache of the website is moved to the visitor, Cloudflare has access to block rare content and store you securely from malicious viruses, spambots and dangerous traffic flow.

How can I use Cloudflare?

What makes Cloudflare so different is the fact that it is not a provider. Once you have the website rising and working, you can replace the DNS settings with Cloudflare hosts, thus holding the website. By replacing the domain name settings that are enabling Cloudflare to hold a copy of the website. With Cloudflare, it has the option of being accessible to enable the type of traffic that it is controlling. This means that if there are errors that pinpoint the generated security warnings or guides of high traffic, Cloudflare will watch and constrain where that malicious traffic is coming from. You will easily know when the site is probably presented with unwanted problems as a result of this.

What does this mean for you? Basically, this means there is always a chance for the company to see the site. The Cloudflare server will request a copy of the web page from the hosting provider and compare the visitor who requested the site to the copy of the web page.

  • There are various plugins that can be used from Cloudflare as well, the most popular of which is Google Analytics. You may ask yourself why this is necessary. Google Analytics is broadly used and chosen for any site on the web for no cost. With the Cloudflare Google Analytics plugin, you do not have to go to the code to add what is used for the plugin to effort.
  • Another great element of Cloudflare is to make the product for the everyday webmaster. Let’s choose that webmasters who are beginning out do not have the professional usage to go into the system embed the Google Analytics code to control site traffic and tracking. What Cloudflare does is use the plugin and transfer the data to Google Analytics, and that’s it. This will delete worries about any tags or make any downtime by embedding the code. This is the thing that Cloudflare takes off the hands.

How do I know that Cloudflare is Right for Me?

When you think about the amount of management that is needed for managing the integrity of one website, imagine how much stress and time is involved in managing various sites. Cloudflare is an option that is at no cost to use as long as you are managing a simple site. There are various paid options that provide more adaptability as well as plugin options so that you can make the best experience for the visitors of the site.

Overall, this service has many options for web management and the chances of weaknesses in the server. For the money, it also gives the advantage of a web hosting service provider without the costly CDN services that are made available through low-end web hosting givers. With the calculated security and speed as the introductory plugins that are available through the latest version, it is worth a try.

If you have any doubt don’t hesitate to ask. Share your doubts and contact us through the given email. Email: [email protected]

What is DevOps?

DevOps is a package of practices and tools that automate and merge the processes between software development and IT groups. It motivates team empowerment, cross-team communication and collaboration. The term DevOps, a combination of the expansion and operations of the word, shows the process of integrating these disciplines into a unit, continuous process.

How does DevOps work?

A DevOps society includes developers and IT operations working collaboratively throughout the business lifecycle, to raise the speed and quality of software development. It’s a new method of working, a social shift, that has significant implications for teams and the organizations they work for. Under a DevOps model, increase and operations teams are no longer “siloed.” Sometimes, these two teams join into a single team where the engineers operate across the entire application lifecycle — from evolution and test to deployment and processes— and have a range of multidisciplinary skills.

DevOps tools are used to automate and stimulate processes, which serves to increase authenticity. A DevOps toolchain helps teams tackle crucial DevOps fundamentals including continuous integration, continuous delivery, automation, and collaboration.

What is the DevOps life cycle?

Because of the eternal nature of DevOps, practitioners use the continuity loop to show how the aspects of the DevOps lifecycle compare to each other. Notwithstanding emerging to flow sequentially, the loop signifies the necessity for continuous collaboration and iterative improvement throughout the entire lifecycle.

The DevOps lifecycle consists of six states enacting the methods, abilities, and tools required for growth and assistance. Throughout each stage, partners cooperate and communicate to maintain alignment, velocity, and quality.

What are DevOps tools?

DevOps tools discuss the key points of the DevOps lifecycle. They enable DevOps trade by helping to increase collaboration, decrease context-switching, inject industrialization, and enable observability and monitoring. DevOps toolchains normally support two passageways: an all-in-one or public toolchain. An all-in-one toolchain grants a perfect solution that normally doesn’t combine with other third-party tools, while an open toolchain deducts for customization with different tools.

What are the benefits of DevOps?

The benefits of DevOps are:

  • Speed:
    Companies that follow DevOps statement deliverables more generally, with greater quality and durability. Some researchers found that elite organizations deploy 208 times more regularly and 106 times more durable than low-performing partners. Constant delivery enables teams to develop, test, and rescue software with automated tools.
  • Improved collaboration:
    The support of DevOps is a history of collaboration among developers and operations partners, who participate in responsibilities and join the craft. This addresses teams more efficiently and keeps time-related to manage handoffs and create code that is intended for the situation where it goes.
  • Rapid deployment:
    By raising the repetition and quickness of releases, DevOps teams develop results quickly. An aggressive benefit can be achieved by quickly delivering new stories and correcting bugs.
  • Quality and reliability:
    Works like continuous synthesis and constant delivery guarantee changes are practical and reliable, which increases the worth of software merchandise. Monitoring supports teams to stay informed of production in real-time.
  • Security:
    By combining safety into constant integration, continuous performance, and continuous deployment pipeline, DevSecOps is an effective, integrated part of the expansion process. Safety is made into the goods by integrating active safety audits and security testing into agile addition and DevOps workflows.

What are the challenges of adopting DevOps?

Habits are hard to break. Partners entrenched in siloed processes of performance can cope with, or even be immune to, improving team constructions to adopt DevOps manners. Some teams may falsely consider new tools are enough to adopt DevOps. Yet, DevOps is a mixture of people, tools, and experience. Everyone on a DevOps team wants to get the entire value stream — from ideation to development, to the end-user experience. It needs to break down silos in series to cooperate throughout the lifecycle of the goods.

Moving from legacy foundation to using IaC and microservices can offer faster growth and innovation, but the improved operational workload can be challenging. It’s enough to build out strong support of automation, shape control, and continuous delivery practices to help ease the load.

An over-dependence on tools can reduce teams from the essential foundations of DevOps: the team and company structure. Once construction is installed, the processes and partners should come attached and the tools should support them.

How to adopt DevOps?

Utilizing DevOps first needs involvement to evaluate and possibly change or remove any teams, tools, or processes your business currently uses. It means producing the essential foundation to give teams the freedom to create, deploy, and manage their outcomes without having to rely too heavily on outside teams.

How to start with DevOps?

The simplest way to get excited with DevOps is to know a small value stream and start searching with some DevOps manners. As with software development, it is far more obvious to change a single stream with a small group of stakeholders than to attempt an all-at-once organizational change to a new way of operating.

How does AWS Auto Scaling ensures you always have enough instances?

AWS autoscaling uses automation to instantly scale materials to fit demand and server load. By accessing AWS Auto Scaling’s tools, you can be very confident that you’ll always have enough instances to get the application load, no matter how better the traffic may spike. And, not only does it execute capacity to make a constant performance, it does so for a small price.

If AWS Auto Scaling sounds like a perfect option for controlling the money and automating resources, it is. But if you’re new to the option you should work with an experienced AWS person. They can tell your so many auto-scaling options, and build and implement an auto-scaling plan for your business’s requirements

AWS Auto Scaling offers multiple features and advantages:

  • AWS Auto Scaling gives a single user interface.
  • The auto-scaling adds computing power to handle the rising application load.
  • Auto-scaling works for EC2 instances.
  • Resource scaling is configured and monitored according to your specific scaling plan.
  • Custom scaling plans are predictive and can help you with load forecasting
  • An AWS consultant can help you customize your auto-scaling plan.

How do AWS autoscaling options meet the requirements perfectly?

Not all AWS Auto Scaling options are created the same, and it’s very important to carefully suggest the plan you go with. Perpetuate Existing Instance Levels Indefinitely The first auto-scaling plan is easy to configure the auto-scaling to maintain a set number of instances. Amazon EC2 auto-scaling routinely scans things to determine their works. If it detects the worst instance, it will end it and start a replacement one. This gives you a predefined number of instances, running at all times.

  • Try to implement Manual Scaling

You can be able to go back to manual scaling, which is the first way of scaling materials. Amazon EC2 Auto Scaling can monitor instance creation and termination to upkeep a constant capacity, which is a value you’ve required. This makes you maintain the maximum and minimum capacity of your options for your auto-scaling team.

  • Scale in Accordance with a Schedule

Scaling programs can be set to activate automatically at a certain time and time. This is really helpful in situations where you can clearly forecast demand. What’s different about this plan is that following a schedule tells the number of available resources at a given period in advance rather than using automation to make appropriate mounts from time to time.

  • Scale Along with Demand

While AWS Auto Scaling can perform all of the more traditional scaling methods mentioned in strategies one through three, scaling along with the demand is where AWS’s special capabilities start to shine. The ability to shift seamlessly between the more old strategies and those discussed in numbers four and five is another nice feature of AWS Auto Scaling in and of itself.

Demand-based scaling is more responsive to fluctuating traffic and helps accommodate traffic spikes you cannot actually tell. That makes it a better all-around, “cover all your bases” all your needs. And it has various settings, too.

  • Use Predictive Scaling:
    At least you can always merge AWS Auto Scaling with Amazon EC2 Auto Scaling to scale resources throughout many apps with predictive scaling. This includes three sub-options:
  • Load Forecasting:
    This method analyzes history for up to 14 days to forecast what demand for the coming two days. Updated every day, the data is created to reflect one-hour intervals.
  • Maximum Capacity Behavior:
    Designate a minimum and maximum capacity value for all materials, and AWS Auto Scaling will keep each resource within that range. This gives AWS some flexibility within set parameters. And, you can control if the apps can add more resources when needs imply forecasted to be above maximum capacity.

When to use AWS Auto Scaling strategies?

There is a fixed time for using these multiple auto-scaling strategies. Basically, they boil down to whether you’re using dynamic scaling. While predictive scaling always predicts future traffic based on past trends, dynamic scaling uses a logical algorithm for automated resource provisioning. If you’re trying to decide which to use or when to start by use metrics to determine traffic and usage patterns. First, determine the stability of usage patterns, as well as the frequency of traffic spikes. Then define what you actually needed.

  • Dynamic scaling: It is the most practical solution in the majority of situations where web traffic varies somewhat evenly over time. But it may not be able to respond quickly to sharp spikes unless your AWS setup is configured for perfect scaling thresholds.
  • Predictive scaling: It should be used when you know to expect an elevated level of usage.

If your apps experience traffic fluctuations on a routine basis, make sure you always have instances to support them using AWS Auto Scaling. Not only does it give the materials you need when you need them most, but it does so for the small cost available.

CentOS Web Panel is a control panel for web hosting. It is a free member to cPanel. It has an easy-to-use user interface and a variety of features for newbies who want to build and manage hosting servers. Using CWP is simple and convenient as you don’t have to get the server with SSH for every little task that needs to be completed.

This blog provides a detailed guide on enabling and using the CentOS Web Panel on CentOS 8.

What are the important points to remember while installing cents web panel:

  • After you install CWP, it cannot be deleted
  • You have to reinstall to delete CWP from your system
  • Your hostname cannot be the same
  • You should only install CWP on a computer with a freshly installed operating system
  • CWP does not support sticky and dynamic

What are the steps to enable the centos panel on centos 8?

  • The first step is to get the server ready
  • The second step is to update the server
  • The next step is the installation of CWP
  • The next step is to configure the centos web panel

How to get the server ready?

First, you need to install the EPEL repository :

$ sudo dnf install epel-release

After that, install the packages required like “wget” for CWP installation by using the below command:

$ sudo dnf install wget -y

Once the required packages are installed, update the host. How to update the server?

Now we will use the command given below to update the host:

$ sudo dnf update -y

We will have to restart the server now to let the updates modify the system. So, restart the system using the command:

$ reboot

After restarting the CentOS 8 system, it is fully set up for installing the CentOS Web Panel.

How to install the CWP?

We are ready to enable CWP on our system now that we have perfectly prepared our server.

First, use the cd command to change your directory to /usr/local/src using the command:

$ cd /usr/local/src

Now use the wget syntax to install the latest version of CWP on your system:

$ sudo wget

Now run the following syntax to install the downloaded shell script:

$ sudo sh cwp-el8-latest

CWP has been perfectly installed. Restart the server again to let the changes take effect:

$ reboot

You can also use the -r flag with the sh syntax to automatically restart the system after CWP is successfully installed:

$ sudo sh cwp-el8-latest -r yes

Now we will be going to learn how to configure and use the CentOS Web Panel on CentOS 8.

How to configure centos web panel?

First, access the Admin Control WebPanel GUI by providing the server IP address and port number 2030.

To check the server IP, open up the terminal of the system on which you enable CWP and enter the below command:

What is Hyper-V?

Hyper-V is Microsoft’s virtualization platform which enables administrators to make better use of their hardware by virtualizing different operating systems to run off the same physical server constantly.

With Hyper-V, you can virtualize operating systems in the data center on your desktop and most everything in between. It is also a perfect tool for programmers that want a safe sandbox to test the software.

Microsoft Hyper-V can be installed and run on desktops Windows, or on servers running Windows Server for server administration services. Here we explain :

At first, you should prepare:

  • A user account with administrator permission and instructions for the computer
  • Enough available memory space to work all the virtual machines you plan to run at the same time
  • BIOS-level hardware support

Adding the Hyper-V role to your Windows

  • First right-click on the Start menu
  • Then click Search In the search bar, if you need to enter the turn windows feature on or off according to the system, the steps will vary.

  • For Windows systems:

  • From the list that given, select Hyper-V.

  • Then click OK.
  • Restart the system
  • For Windows Server systems:

  • From the given option Add Roles and Features Wizard, click Next

  • Select Role-based or specific-based installation. Click Next
  • Select the tool: Select a server from the server pool. Click Next
  • Then Select Hyper-V
  • Next to Click Add Features
  • Then Click Next
  • Next to Click Next
  • Then at last Click Next

Creating a Virtual Network Switch

  1. First, open up Hyper-V Manager.
  2. Next Right-click on the Hyper-V host and select Virtual Manager
  3. Then Under Virtual Switches, select New virtual network switch
  4. Ok next Under What type of virtual switch do you want to create?, select External
  5. Then click Create Virtual Switch
  6. Next, you Under Virtual Switch Properties, give the new switch a name, such as External VM Switch
  7. Then Under Connection Type, ensure External Network has been selected
  8. Next, you should select the external network card to be paired with the new switch. This is the card physically connected to the network
  9. Then next Click Apply to create the virtual switch. You’ll most likely see the following message. Click Yes to continue
  10. Next, you should Click OK to close the Switch Manager window

How to Create a virtual machine with Hyper-V?

  1. The first step you have to do, in Hyper-V Manager, click Action > New > Virtual Machine to bring up the new Virtual Machine wizard.
  2. Then review the Before You Begin content, then click Next
  3. Next, give the virtual machine a name
  4. Then you have to choose a location where the virtual machine files will be stored, such as c:\virtualmachine. You can also access the location
  5. Then Click Next
  6. Next, you should Select Generation 1 for the machine and click Next
  7. Then Select 2048 MB for the Startup Memory value and leave Use Dynamic Memory selected. Click Next. On the Connection Networking, click on a virtual switch for the virtual machine and click Next. For more details, see Creating a Virtual Switch.
  8. Next, you should give the virtual hard drive a name, select a location or keep the default, and specify a size. Click Next.
  9. Then, On the Options wizard, select Install an operating system from a bootable image file, then select an operating system .iso file. Click Next.
  10. Next, When you create a virtual machine, you can connect some operating system installation options. The three options available are: * Install an operating system later.
    * Install an operating system from a bootable file – similar to inserting a CD into the l CD-ROM drive of a physical computer. To connect this option, select a .iso image. This image will be merged with the virtual CD-ROM of the virtual machine. The boot order of the virtual machine is replaced to boot first from the CD-ROM. * Install an os from a network-based installation server – not available unless you’ve configured the virtual machine to a network switch. In this connection, the virtual machine needs to boot from the network.
  11. The last step is to review the virtual machine details and click Finish to complete the virtual machine creation.

How to Configure a Subdomain in Apache2?

Being a cloud service providing company, in this blog, we taught you about How to set up subdomains on the Apache HTTP server.

A subdomain is a precursor that can be set up on a domain name. For instance, in "" the word "key" is the subdomain of the "" domain name.

How To Change Dns Zone File?

Before digging into the server to create a subdomain in apache2, let the domain name registrar know of the subdomains that you wanted to use. To do this, signed onto the registrar's site for managing the domain names, and went to edit the DNS Zone File.

A DNS Zone File is used by Internet routers to keep perfect track of where to send traffic that comes to the domain name. Mail traffic can be sent to the mail server, while FTP traffic could be to a server with a variety of IP addresses, and so on. Because Zone Files are not patriarchal, each subdomain must have its own way of the entry point in the file.

Anyway, when you got to the margin where you could edit my DNS Zone File, looked for the "CName" table, which documents the "alias" records. To create a replacement thanks to entering, add the name of your subdomain under the host column, and an "@" sign under the "points to" column.

The given "@" is shorthand for the IP address of the domain name that we are providing, which was defined in the Host table in the DNS Zone File. And that's it, basically. Except for a bit of waiting.

It usually takes about an hour for the changes to the Zone File to discover across the Net. make sure and correct that if it has been activated by pinging it to see if you get a response back. In the first, the subdomain has been registered within the zone file. In the second, that subdomain that we gave has not been registered. If you're following along, you would possibly be noticed that once you enter the address into a browser -- once the Zone File has propagated across the web -- the server changes the way of you to the main site's home page. That's a start.

How to change Apache settings?

In effect, you've learned how the planet beat a road to your subdomain, and therefore the remainder of the work cares about fixing the server to field the requests correctly! Now, it's time to configure Apache!

At the command line, open the "apache2.conf" in the /etc/apache2 directory. As the name prefers it is the configuration file for Apache. At the down margin of the apache2.conf file, after the last commented text, "#Include the virtual host configurations" is the place that you need to add your additional configuration instructions that Apache will chase once it is restarted.

A virtual host, defined as Apache in code, allows a single instance of Apache to run different sites. Each site that we are hosting gets its own configuration entry in apache2.conf file. In Apache technical follow-up, create multiple name-based virtual hosts for the same IP number.

Depending on how your page of Apache has been set up you may already see an entry for a virtual host, for the main site for the domain. For example, it'll appear as if this:

DocumentRoot /var/www

where the host IP number ( is assigned to a specific domain name.

To add a support tool for subdomains, create a VirtualHost entry for each subdomain, using the same IP number. So for and, add these entries respectively.

DocumentRoot /var/www/Technique
DocumentRoot /var/www/fishing

In these examples, the Host IP number is the same as the actual site. The name of the server entry indicated the name of the fully qualified address of the subdomain and the DocumentRoot indicated where the root directory for this subdomain exists in the server's own file system.


In effect, you could make a full site for the subdomain, based on the root document directory. Note you would like an index.html within the subdomain's root directory for Apache to display some content when is named.

And, as always, remember to restart your Apache server after making any configurations. In Ubuntu, it is done easily at the command line:

service apache2 restart:

/etc/init.d/apache2 restart
