How to Install CentOS 7 Step by Step with Screenshots.

inally the much awaited CentOS 7 is out. CentOS (Community Enterprise Operating System) is forked from RedHat Linux, a Linux Distro fine tuned for servers.

In this article you will learn how to install CentOS 7 in a few easy steps.

Step 1: Download The ISO Image

To get a copy of CentOS 7 download from its source mirror. CentOS 7 is now shipping for 64 bit platforms, and currently there is no 32 bit ISO image. This is primarily due to the fact that most servers in production are 64 bit.

Step 2: Make A bootable Drive

After you have downloaded the ISO image, make a bootable USB drive using Unetbootin. Alternatively you can burn a DVD drive using Brasero or your favourite CD/DVD burning software.

Step 3: Begin Installation

To begin installation, click on the Install to Hard Drive icon on the desktop.

Step 4: Select Language And Keyboard

Select your preferred language as well as the Keyboard type you have. Take care not forget to choose the correct keyboard or else you will end up with a few scrambled keys.

Select Language

Step 5: Change The Installation Destination

By default the Anaconda installer will choose automatic partitioning for your hard disk. Click on the Installation Destination icon to change this to custom partitioning.

Step 7: Create A Swap Space

You can create a swap space from one of the partitions and set the desired capacity, which is dependent on the RAM you have. Choose the File System for swap space as swap, and click on Reformat, though reformatting is optional. You can also name your swap space to whatever name you like but a name like swap is more descriptive.

Step 8: Create A Mount Point

The next step is to create a mount point where the root partition will be installed. Depending on your requirements you might need to put the boot, home and root partition on different mount points. For this case we shall have only one mount point /.

After this set the Label and Desired Capacity to whatever you wish. A rule of thumb is to use descriptive names for the Label especially if the computer is to be used by different system administrators.

Choose the file system as ext4 and click on reformat.

CentOS 7 comes with GRUB 2 which solves dual booting problems with other Linux distros that have been using GRUB 2, like Ubuntu. This is an improvement from CentOS 6.5 which used GRUB Legacy and was a problem when dual booting. Now you can do your installation without concerns of GRUB issues.

CentOS 7 has support for the xfs file system which is suitable especially in a distributed type of environment. XFS is known for its ability to handle parallel I/O compared to ext4.
