How To Install CentOS 7 On Fresh System

After waiting long finally CentOS 7 is out. CentOS ( Community Enterprise Operating System ) is forked from RedHat Linux, Linux distro fine tuned for servers.

In this article I will show you how to install CentOS 7 in a few steps.

First you will need to download CentOS 7 iso image from its source mirror. CentOS 7 is only available in 64 Bit platforms and currently there is no 32 Bit iso image. Because most of the production servers comes in 64 Bit.

Step #2: Make A Bootable Drive

After downloaded the ISO image, you will need to make bootable USB drive. You can create usb drive bootable by simply transferring iso file to usb using dd command since CentOS 6.5 or alternative you can use Win32DiskImager, Unetbootin no longer works for CentOS 7.

# dd if=/iso/CentOS-7-x86_64-DVD-1602-99.iso of=/dev/sdb

* /dev/sdb is the usb device and make sure you have atleast 4.3 GB space.
