How to Install CentOS 7 (Easiest Guide With Screenshots)

CentOS 7 is the big major release of the CentOS Linux distribution. It is based on Red Hat Enterprise Linux 7, which is derived from Fedora Linux version 19. It was first released on July 7th, 2014 and will be supported for 10 years, up through June 30th, 2024.

The OS Selection should be compatible for what we are setting up on the server, this is the most important thing. I will recommend to select CentOS 7 because this supports almost is all the hardware.

CentOS 7 includes several major changes that pertain to booting up and managing the system. It is the first to introduce “systemd” which controls how services are started up, as well as many system settings. It also includes “firewalld” as a new method of managing the server’s firewall.

CentOS 7 also provides updates most common hosting software. I have setup SMTP, WordPress, SQL and some other email marketing on the CentOS 7 which is running smoothly.
