This blog post is showing you how to install nginx, php and mariadb (LEMP) on Centos 8. After having LEMP installed, you can install wordpress. Installing wordpress with nginx on Centos 8 is not a hard task. To do so, follow these steps.

1. Install Nginx

2. Install mariadb server


yum install mariadb-server

Start mariadb server


systemctl start mariadb

Restart mariadb server


systemctl restart mariadb

Status of the mariadb server


systemctl status mariadb

To secure mariadb server, do this.


mysql_secure_installation

The following will be prompted.

● Enter current password for root (enter for none): --> Hit enter

● Set root password? --> Y

● Remove anonymous users? --> Y

● Disallow root login remotely? --> Y

● Reload privilege tables now? --> Y


NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

3. Install PHP


yum -y install php php-mysqlnd php-json

Create a file named info.php


nano /var/www/html/info.php

Put the following lines inside it.
