Introduction
This how-to will show you how to install WordPress on CentOS 8. WordPress started as a blogging system, but now has become a full content management system (CMS). Since WordPress is a free open source program, it has become the most popular CMS on the Web. With thousands of plugins, your website is nearly limitless.

Prerequisite
– To install WordPress, a CentOS 8 server running LAMP or LEMP is required.
Install WordPress on CentOS 8
To install WordPress, we are going to start off by setting up the database by running the following commands:
mysql -u root -p
When prompted, enter your MySQL root password that you set up when installing MySQL.
In MySQL, enter the following commands:
create database wordpress character set utf8 collate utf8_bin;
Make sure you set your own secure password where it says [insert-password-here]
grant all privileges on wordpress.* to wordpressuser@localhost identified by '[insert-password-here]';
flush privileges;
exit
Now that the database is created, we can download the latest version of WordPress with the following command:
wget http://wordpress.org/latest.tar.gz
Note: if wget is not installed, install it by running the command:
yum install wget
The latest package will download to the directory you are currently in, with the file name latest.tar.gz. We need to decompress the file by running:
tar -xzvf latest.tar.gz
Next, we need to copy wp-config-sample.php to wp-config.php which is where WordPress gets its base configuration. To do that run:
cp wordpress/wp-config-sample.php wordpress/wp-config.php
In your favorite text editor, edit wordpress/wp-config.php
For a basic setup, we need to have the following.
define(‘DB_NAME’, ‘wordpress’);
define(‘DB_USER’, ‘wordpressuser’);
define(‘DB_PASSWORD’, ‘[insert-password-here]’);
It should look like this when completed:
wp-config.php
Next, we need to move the WordPress folder to your web directory.
sudo cp -r ~/wordpress/* /var/www/html
We now can go to the WordPress web installation. In your browser go to http://yourhostname-or-ipaddress
If you are unsure what you IP address is run the following:
ifconfig
ifconfig
In our example, we would put http://192.68.0.2/ in the address bar and get the following page.
