WordPress is not available in the official package repository of CentOS 8. So, you must download it from the official website of WordPress and install it on CentOS 8. It’s very easy.

First, navigate to the /var/www directory as follows:

Now, download the latest WordPress archive from the official website of WordPress with the following command:

wget is downloading WordPress archive. It may take a few minutes to complete.

WordPress archive should be downloaded.

The WordPress archive file latest.tar.gz should be in the /var/www directory as you can see in the screenshot below.

Now, extract the WordPress archive file latest.tar.gz with the following command:

Once the WordPress archive file latest.tar.gz is extracted, a new directory wordpress/ should be created as you can see in the screenshot below.

Now, you can remove the latest.tar.gz file as follows:

Now, change the owner and group of the wordpress/ directory and its contents to apache as follows:

Now, change the permission or the wordpress/ directory and its content to 775 as follows:

If you have SELinux enabled (which is very likely on CentOS 8/RHEL 8), run the following command to set the correct SELinux context to the /var/www/wordpress directory and its contents.

For the SELinux changes to take effect, run the following command:

Now, create a new Apache configuration file wordpress.conf for WordPress with the following command:

Apache http service should be active without any errors as you can see in the screenshot below.

Accessing WordPress:

In order to access WordPress installed on your CentOS 8 machine, you must know the IP address or domain name of your CentOS 8 machine.

You can find the IP address of your CentOS 8 machine with the following command:

As you can see, the IP address of my CentOS 8 machine is 192.168.20.129. It will be different for you. So, make sure to replace it with yours from now on.

Now, open your favorite web browser and visit http://192.168.20.129. You should see the following page. Click on Let’s go.

Now, type in the MariaDB database information (i.e. Database Name, Username, Password). Leave the Database Host and Table Prefix as it is if you don’t know what they are. Once you’re done, click on Submit

Now, click on Run the installation.

Now, type in your site details and click on Install WordPress.

Don’t forget to take a note of the Username and Password you’re setting here as you will need them very shortly.

WordPress should be installed. Now, click on Log In.
