How To Install Linux, Nginx, MariaDB, PHP (LEMP Stack) On CentOS 8 / RHEL 8

Nginx is an open-source, high-performance web server. It is known for its stability, very simple configuration, rich feature set, and low resource consumption.

Nginx lets you use it as a reverse proxy, load balancer, HTTP cache, and mail proxy.

This post shows you how to install Nginx on CentOS 8 / RHEL 8 with PHP support (through PHP-FPM) and MariaDB support.


PHP-FPM is an alternative PHP FastCGI implementation. It has additional features that are useful for sites of any size, especially busier sites.

By now, you should have a Linux system ready with you. Now, we will install Nginx, MariaDB, and PHP-FPM on top of it.

The steps mentioned in this article will only work if you have enabled Red Hat subscription on RHEL 8 or configured the local yum repository on your system.

Log in into the system as the root user or switch to the root user.

Install Nginx

Install Nginx using Base Repository

In RHEL 8, Nginx is available in the rhel-8-for-x86_64-appstream-rpms repository. So, we do not need to set up the Nginx repository manually.

Install Nginx using the YUM command.

yum -y install nginx

Install Nginx using Nginx’s Official Repository

Add Nginx repository to your system.

### CentOS 8 ###

cat << EOF > /etc/yum.repos.d/nginx.repo
name=nginx mainline repo

### RHEL 8 ###

cat << EOF > /etc/yum.repos.d/nginx.repo
name=nginx mainline repo

Install Nginx from Nginx’s official repository by temporarily disabling AppStream repository.

yum install -y nginx --disablerepo=* --enablerepo=nginx-mainline

Start the Nginx web server service after the installation.

systemctl start nginx

Check the status Nginx web server service using the below command.

systemctl status nginx

firewall-cmd --reload


If you get any error for SELinux on Nginx logs, here is the tutorial on setting SELinux policy for Nginx.

Else, you can temporarily disable the SELinux using the following command. But, we suggest you disable the SELinux permanently.

setenforce 0

sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

Verify Nginx Installation

Open your web browser and visit the below URL.

Edit /etc/php.ini.

vi /etc/php.ini

set cgi.fix_pathinfo to 0.


Edit /etc/php-fpm.d/www.conf file.

vi /etc/php-fpm.d/www.conf

Make sure the following values are UN-commented.


pm.min_spare_servers = 5	 	 


pm.max_spare_servers = 35	 	 


Change the Listen parameter.


listen = /run/php-fpm/www.sock


listen =

Then, start the PHP-FPM service.

systemctl start php-fpm

Enable PHP-FPM service to start automatically on system boot.

systemctl enable php-fpm

Enable PHP-FPM Support on Virtual Host

We will now create a virtual host on Nginx server for the following details to test the PHP.

Server Name: web.itzgeek.local
Document Root: /usr/share/nginx/html/web.itzgeek.local

Create a configuration file called web.itzgeek.local.conf under /etc/nginx/conf.d and edit it.

vi /etc/nginx/conf.d/web.itzgeek.local.conf

Add the following content.

server {
   server_name web.itzgeek.local;
   root /usr/share/nginx/html/web.itzgeek.local;

   location / {
       index index.html index.htm index.php;

   location ~ \.php$ {
      include /etc/nginx/fastcgi_params;
      fastcgi_index index.php;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

Create a document root directory.

mkdir /usr/share/nginx/html/web.itzgeek.local

For testing the PHP, we will place a PHP file on to the document root of the created virtual host.

echo "<?php phpinfo(); ?>" > /usr/share/nginx/html/web.itzgeek.local/index.php

Restart the services.

systemctl restart nginx

systemctl restart php-fpm

Test LEMP Stack

Create host entry for your web server domain (server.itzgeek.local) in the /etc/hosts (Linux) and hosts file (Windows).             web.itzgeek.local

Open a web browser and enter your domain in the address bar.
