Installing NGINX on Redhat/CentOS

Nginx can be installed in two ways:

• We can install Nginx from default RHEL or CentOS repository. This is the easiest and quickest way, but generally, the provided packages are outdated.
• We can also install Nginx from the official repo at nginx.org. For this, we have to set up the yum repository for the first time only, but after that, the provided package is always up to date.

Installing Nginx from OS repository

Step 1: Install the EPEL repository for Nginx package:

Here, EPEL stands for Extra Packages for Enterprise Linux. Since, yum as a package manager does not include the latest version of Nginx in its default repository; installing EPEL will make sure that Nginx on RHEL or CentOS stays up to date.

Use the following command to install the Epel repository.

• this element is the release number such as 6, 6._x, 7, 7._x_ and so on.
