CentOS is a free, enterprise-class, community-supported Linux distribution. It is referred to as a free version of RedHat Enterprise Linux distro.
In this tutorial, we will show you how to install CentOS 6 on VirtualBox on Windows. For this, you will need to have VirtualBox installed, and download Centos 6 ISO file from the official servers.
Installing CentOS 6 on VirtualBox on Windows
We will be installing a minimal installation, which means that only the terminal will be installed, without the graphics environment. Good thing is that we can still install the graphics environment from the terminal if we ever need it.
Step 1 – Downloading CentOS 6 ISO
To install it, we must first download the CentOS 6. It comes in a form of ISO file (virtual CD), which can be downloaded from multiple locations, called mirrors. You can enter this link, and see a list of mirrors around the world. Make sure to click on the “Minimal ISO” button. Choose the one that is geographically nearest to you, we chose the first one, proposed by the site itself.
Once clicked, it offers us the following options:
You can download the torrent file as well. The latest version of CentOS 6 at the moment is 6.10, and we should download the minimal ISO file now.
Wait for it to download, and we can move on to VirtualBox setup.
Step 2 – Creating a New Virtual Machine in VirtualBox
We assume that you have VirtualBox installed. VirtualBox is a great virtualization platform, and besides that, it is free.
So let’s open VirtualBox, go to New virtual machine, and select these options
You can call it whatever you want, we called mine FOSS. The type must be Linux, and since there is no option for CentOS, you can use RedHat (32 or 64-bit version, depending on your system).
After all, CentOS is a clone of Red Hat Enterprise Linux.
Click Next, and you are taken to the screen where you must decide how much memory guest will take. The default is 1GByte, and it is a reasonable value for a terminal-only installation.
We will choose to create a new hard disk on the next screen
Next, we can leave the virtual disk type as VDI, other options are useful if we are working with other virtualization software.
Now, we must choose whether to use fixed-size or dynamically expanding disk space. The first choice takes as much disk space as we define virtual disk space. The second option takes only a small amount of disk space, and it grows as data is added to virtual disks.
The default option is dynamically allocated, and it is a good choice, although a little bit slower one. Click next, and your virtual machine is created.
It is in a powered off state. Before we turn it on, we must do two things: specify the ISO file from which an operating system will be installed, and specify network type.
Step 3 – Specifying the Installation Media
First, let’s specify the ISO file by right-clicking on a virtual machine, choose Settings, and then Storage. Click on the disk icon right of Optical Drive, it will allow you to choose an ISO file that will serve as a virtual disk. Choose the CentOS ISO that you downloaded previously.
Click on the disk icon right of Optical Drive, it will allow you to choose an ISO file that will serve as a virtual disk. Choose the CentOS ISO that you downloaded previously.
Step 4 – Configuring Network Type
We still need to configure the network. I am using my laptop with Windows 10 to run VirtualBox. It connects to the internet via an ADSL modem, which gives it automatic (via DHCP) or static address (if you configure one yourself). By default, virtual machines use NAT or Network Address Translation, which uses the same IP address as my laptop. I will do something else I will use something called Bridged Networking, which will allow my VirtualBox CentOS to have a separate IP address, in the same subnet.
For that, let’s choose Network form the same settings window that we opened, and instead of the default NAT, use Bridged Adapter.
During the installation process, we will assign a static IP address manually for the CentOS virtual machine. We need to know what our laptop’s IP is, so we can choose an address in that same subnet. Open the command prompt by entering cmd in the windows search box, and enter the ipconfig command
We can see that the IP of a laptop is 192.168.1.41, so we will assign a random address like 192.168.1.111 for our Linux installation. Your IP may be different, just make sure that you choose Linux IP in the same subnet. It is wise to choose a higher last number, like 111, or 188, because there is less chance that it will be taken by some other device on your network. Write this address somewhere, you will need it during the installation process.
Step 5 – The Installation
The installation itself begins with the right-clicking on the virtual machine and selecting Start->Normal Start. Soon, you are prompted to choose what to do next. Click inside a window and choose Install or upgrade an existing system.
Landscape architectural graphic standards …. You may notice that your mouse pointer is “captured” inside a window. To get out, press right CTRL key.
Next screen that appears asks you if you want to check installation media. I usually skip that and move forward.
We need to choose the installation language and the keyboard layout. Choose appropriate options and proceed.
Virtual hard disk must be initialized, so accept Yes, discard any data.
Next screen allows us to specify the hostname of the Linux virtual machine. I choose centos7.fosslinux.com. It is only local and does not apply across the Internet, of course.
Don’t click Next yet, because on this screen there is an option Configure Network. Choose it, and a window appears, where you should select System etho and click Edit.
In the window that appears, check Connect Automatically, otherwise, the network will not work when you start the virtual machine. Select tab IPv4 settings.
In Method drop-down list, instead of the default Automatic(DHCP), choose Manual, click Add and in the fields that appear, insert the IP address for our virtual machine(you wrote it down, right?), netmask (usually 24),and gateway (the address of my ADSL gateway). For DNS server, if you are using ADSL as I am, it is the same as gateway, 192.168.1.1, if you are in some kind of LAN that has a dedicated DNS server, you should put the IP address of that DNS.
Click Apply, close Configure Network and click Next.
We need to set the time zone on the next screen, and we can do it either by clicking on a map to choose our location or from a drop-down list below.
We also need to set the root password. Select something that can not be easily guessed, and which preferably includes an uppercase and lowercase letter, numbers, and special characters.
On the next screen, choose to use all space, since we don’t need to keep any data or previous partition layout.
Now everything is ready for the installation. You can still go back to review something or Write changes to disk.
The installation will now begin – creating a filesystem and installing necessary packages. Based on your processor, disk speed and available memory, it will take a few minutes at most. At the end of the installation, you will get a message that the installation is finished and you must reboot the virtual machine.
Reboot the system by either right-clicking virtual machine and choosing Reset or by choosing Input->Keyboard->Send CTRL+ALT+DEL in virtual machine window.
Once a virtual machine resets, you are presented with a login screen. Congratulations, you have successfully installed Centos 7 on VirtualBox.

2. Introduction
Welcome to the CentOS 6.10 release. CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by Red Hat1. You can read our official product announcement for this release here
CentOS conforms fully with Red Hat's redistribution policy and aims to be functionally compatible. CentOS mainly changes packages to remove upstream vendor branding and artwork.
The Continuous Release (CR) repository makes generally available packages that will appear in the next point release of CentOS, on a testing and hotfix basis until formally released.
Please read through the other sections before trying an install or reporting an issue.
NOTE: There is NO mechanism to pick only partial upgrades of packages to CentOS-6.10. All packages and updates to the 6.10 tree are built against the 6.10 tree and may not work correctly with older 6.x packages. If you want some packages in 6.10, please upgrade all packages. You will have issues if you perform only partial updates.
3. Install Media and sha256sum
- The installation kit is split into two DVDs. It is possible to do a full install with only the first DVD. The second DVD contains only supplementary RPMs, which can be installed afterwards if needed. The installer does not ask for the second DVD during installation. You should check the sha256sum of the downloaded installation images.
- ISO downloads are available here
4. Major changes
- The following packages have been rebased to a newer upstream release: pacemaker, clufter, gcc-libraries
- GCC now supports retpolines, which aids in mitigating Spectre Variant 2 attacks
- iptables-services can now read configuration files from /etc/sysctl.d
- BIND contains the new root KSK in preparation for the upcoming DNSSEC Root Zone Key-Signing-Key rollover

TLS compression support has been removed from NSS to prevent security risks.
Mozilla no longer includes code signing trust attributes in their CA trust list. The ca-certificates package has been modified to reinclude those code signing trust attributes by default. The ca-legacy command can be used to select whether the unmodified Mozilla CA trust list should be used or not.
ipt and xt actions have been dropped from iproute due to long-standing issues with those actions.
Please see the Red Hat Technical Notes for more details concerning deprecated and removed functionality.
6. Known Issues
- On UEFI-capable systems, CentOS 6.x writes its boot configuration to /boot/efi/EFI/redhat. This will cause problems for those who want to have CentOS and RHEL installed on the same system. This issue may remain unfixed for the lifetime of CentOS 6. CentOS 7 does not have this issue.
- UEFI on CentOS-6.10: None of the i386 (32 bit) CentOS-6.10 ISOs will work with UEFI. All the x86_64 CentOS-6.10 ISOs (except LiveDVD) should boot and work with UEFI. No versions of CentOS 6 will work with Secure Boot turned on. Secure Boot must be disabled to install CentOS 6. For further detail please take a look at CentOS Bug #6321.
- Even though there is an option for upgrading when booting from the .iso images, the recommended way of upgrading is via yum update. Minimal will only update the packages that reside on the minimal iso, and when booting from DVD, the installer can't handle switching to the 2nd DVD if upgrading a package that resides on the 2nd DVD.
- On Intel and AMD based processor architectures, CentOS 6 requires PAE support for 32-bit x86 chips, following the upstream's requirement
- The installer needs at least 406MB of memory to work. Text mode will automatically be used if the system has less than 632MB of memory.
- The text installer has limited capabilities compared to the GUI installer. Most notably there is no support for configuring partition layout, storage methods or package selection. Please refer to the official documentation for details. Here you can find some useful information on creating and using kickstart files which can be used to perform advanced configuring without the need for the GUI installer.
- The message 'Insufficient memory to configure kdump!' appears during install. This is a known issue which appears on systems with less than 2 GB RAM. This can be ignored.
- Make sure that you setup correctly the selinux context of the public key if you transfer it to a CentOS 6 server with selinux enabled. Otherwise selinux might forbid access to the ~/.ssh/authorized_keys file and by matter of consequence key authentication will not work. In order to setup the correct context you can use: ssh-copy-id from CentOS 6 is aware of selinux contexts and the previous workaround is not needed.
- Many people have complained that Ethernet interfaces are not started with the new default NetworkManager tool. See CentOS-6 FAQ#2.
- Several packages have .centos. in their name but are not modified packages, see CentOS Bug #5281 for details. Here are the SRPMS still affected in the 6.10:
- at-spi
- gtk2-engines
- libgail-gnome
- There is an issue with loading the ipv6 kernel module in some cases, which produces this error: Unknown symbol unregister_inet6addr_notifier . See bug 10927 for details.
- Due to the changes in the Xorg subsystem the VirtualBox Tools have to be rebuilt for the GUI to start
- If you use the SCL or Xen4CentOS repositories the locations of these have changed as these repos are now being maintained by Special Interest Groups. If you get errors updating your SCLs, do: yum remove centos-release-SCL then yum install centos-release-scl-rh. Xen should update as part of the normal update process.
- One can do USB key installs by using dd to copy individual ISO files to a USB key using the device name (not the partition name). This will overwrite the entire USB key. Here is an example for the DVD1:

9. How to help and get help
As a CentOS user there are various ways you can help out with the CentOS community. Take a look at our Contribute page for further information on how to get involved.
9.1. Special Interest Groups
CentOS consists of different Special Interest Groups (SIGs) that bring together people with similar interests. The following SIGs already exist:
- Artwork - create and improve artwork for CentOS releases and promotion
- Promotion - help promoting CentOS online or at events
- Virtualization - unite people around virtualization in CentOS
Redhat 6.10 Download
And we encourage people to join any of these SIGs or start up a new SIG, e.g.
- Alpha, S390, Sparc and PPC port - help with porting CentOS to other architectures
- Hardware compatibility - provide feedback about specific hardware
- RPM Packaging - contribute new useful RPM packages
- Translation - help translating the documentation, website and Wiki content
9.2. Mailinglists and Fora
Another way you can help others in the community is by actively helping and resolving problems that users come up against in the mailing lists and the fora.
9.3. Wiki and Website
Even as an inexperienced CentOS user we can use your help. Because we like to know what problems you encountered, if you had problems finding specific information, how you would improve documentation so it becomes more accessible. This kind of feedback is as valuable to others as it would have been to you so your involvement is required to make CentOS better.
So if you want to help out and improve our documentation and Wiki, register on the Wiki or subscribe to the centos-docs mailing list.
