CentOS 6.7 Server
Installing CentOS 6.7 Server - Minimal Build
Installing Centos 6.7
CentOS (Community Enterprise Operating System) is a free Linux operating system that has 100% binary comparability with RHEL (Red Hat Enterprise Linux). Because of this compatibility, many organisations choose CentOS as their choice of Linux. In the example that follows, we will show you how to install a minimal build server without a graphical user desktop. To install CentOS 6.7 (minimal build) simply follow the instructions below:
To download your iso image of CentOS 6.7, simply follow this Link: CentOS 6.7 Download
For a 64 bit version, choose the x86_64 folder and for a 32bit version choose the i386 folder. In the example that follows I have used the 64 bit version FileName: CentOS-6.7-x86_64-minimal.iso
Once you have downloaded your CentOS 6.7 iso for your chosen architecture (32 bit or 64 bit), you will need to burn this to a blank CD/DVD. For software that can do this, search for "dvd iso burning software" in the search box located at the top of this page. Your system may already have CD/DVD burning software installed such as "Brasero, K3B, Nero, CDBurnerXP or Roxio". Once you have burned your "iso" image of CentOS 6.4 to your DVD, you will need to leave the DVD in the DVD drive and reboot your system. (This example assumes you are using a i386 32bit version of the software). As your computer reboots, you will need to press the appropriate key to access your system's BIOS settings. On many systems this key will be "F8", "F11" or "F12". Most systems will display the a message indicating which key needs to be pressed. Once you have access to your BIOS settings, you will need to modify the boot sequence order of your system to boot from CD/DVD first. Once you have made this change, you can reboot your system and follow the instructions below.
Welcome to CentOS 6.7 Installation Menu
To start your installation of Centos 6.7, simply highlight the "Install or upgrade an existing system" and press enter. Your installation will now start.
Testing Installation Media
It's always recommended that you should test your installation media before carrying out an installation. If you are happy that your media is OK, then select "skip" to continue.
Welcome to CentOS for x86_64
At this screen click on the "OK" button to continue with your installation.
At this screen you will need to select the language that is to be used throughout the installation. In this example "English" has been selected.
Select keyboard type. In this example I have chosen a "UK" keyboard.
Storage Device Warning
From this screen you must confirm that any data on the specified disk can be discarded. Choose the option "Re-initialize all".
Select Time Zone Location
Choose the location that you are located in. In the example, I have chosen "Europe/London" as this is my location.
Pick a "root" password to be used on your system.
The installation now requires partitioning of your hard drive. Confirm which drive you are using. Once happy with your selections, click on"OK" to continue. In the example I have chosen "Use Entire Drive" as this is a virtual disk and no other operating systems are present.
Write Storage Configuration to Disk
If you are happy with your selections, then choose "Write changes to disk" to continue with the installation.
At this stage, no further action is needed. The minimal build packages are being installed. Progress is indicated by the progress line.
Congratulations, your minimal CentOS 6.7 installation is now complete. You must remove any media from your CD/DVD drive and reboot your system.
CentOS Loading Screen
If all goes well, you should see the following loading screen while your system is booting.
CentOS Login Screen
If all goes well, you should now see the following login screen. Here you will need to login as the "root" user, using the password you specified in a previous step
Configure Hostname and Activate Network Settings
To configure the hostname on your system, you will need to edit the following file:
You will need to change the line that begins "HOSTNAME". In this example, I have given the name "centos67a".
Amend the the following line to read: ONBOOT=yes
Below is an image of what the configuration files have been changed to on this example installation.
After we have made the changes, it is a good time to carry out a test reboot. This will verify our changes above. To reboot your server, you will need to issue the following command:
shutdown -r now
This will reboot the system and you will be taken back to the login screen. Here you can login and you will be able to see the new hostname that you specified. You can check you IP address assignment by issuing the command: ip a s
