Install WordPress on Rocky Linux 9 [Step-by-Step]

WordPress is a free CMS (Content Management System), content management system written using PHP and MySQL, licensed under the GPL. WordPress is a platform where all kinds of content can be edited and published, not just as an article writing and editing or blogging system.

64.4% of known content management systems and 43% of all websites use WordPress. Let's talk about installing this popular CMS software on Rocky Linux 9.

 

Steps to install WordPress

Let's explain the installation step by step.

 

Step 1: Install Httpd and LAMP Stack

For the WordPress web interface, the httpd package is first installed:

[foc@rocky9 ~]$ sudo dnf install httpd -y

Then httpd service is enabled:

[foc@rocky9 ~]$ sudo systemctl enable httpd
Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service → /usr/lib/systemd/system/httpd.service.

And the service is started:

[foc@rocky9 ~]$ sudo systemctl start httpd

Added firewall rules for httpd service:

[foc@rocky9 ~]$ sudo firewall-cmd --add-service=http --permanent 
success

[foc@rocky9 ~]$ sudo firewall-cmd --reload
success

A LAMP stack is a group of open-source software that is typically installed together to enable a server to host dynamic websites and web apps. You can find more detailed information about LAMP Stack installation in our "Install LAMP Stack on Rocky Linux 8 [Step-by-Step]" article. Now let's proceed by installing the necessary LAMP Stack packages for WordPress installation:

[foc@rocky9 ~]$ sudo dnf install -y php php-zip php-intl php-mysqlnd php-dom php-simplexml php-xml php-xmlreader php-curl php-exif php-ftp php-gd php-iconv php-json php-mbstring php-posix php-sockets php-tokenizer

This step is complete

 

Step 2: Create the Database and a User

If you want to do database operations with phpMyAdmin, not from the terminal, you can review the "Install phpMyAdmin on Rocky Linux 9 [Step-by-Step]" article for phpMyAdmin installation.

For MariaDB Server, install the following package:

[foc@rocky9 ~]$ sudo dnf -y install mariadb-server

The service is enabled:

[foc@rocky9 ~]$ sudo systemctl enable mariadb.service
Created symlink /etc/systemd/system/mysql.service → /usr/lib/systemd/system/mariadb.service.
Created symlink /etc/systemd/system/mysqld.service → /usr/lib/systemd/system/mariadb.service.
Created symlink /etc/systemd/system/multi-user.target.wants/mariadb.service → /usr/lib/systemd/system/mariadb.service.

Then the service is started:

[foc@rocky9 ~]$ sudo systemctl start mariadb.service

We will create a database for user, password and wordpress in MariaDB. Enter MariaDB:

[foc@rocky9 ~]$ sudo mysql -uroot
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 4
Server version: 10.5.16-MariaDB MariaDB Server

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> CREATE DATABASE mywordpress_db;
Query OK, 1 row affected (0.000 sec)

MariaDB [(none)]> CREATE USER 'wp_foc'@'localhost' IDENTIFIED BY 'Pp123456';
Query OK, 0 rows affected (0.005 sec)

MariaDB [(none)]> GRANT ALL ON mywordpress_db.* TO 'wp_foc'@'localhost';
Query OK, 0 rows affected (0.005 sec)

MariaDB [(none)]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.000 sec)

MariaDB [(none)]> exit;
Bye

We entered the following values, make a note of the information you entered:

• Database: mywordpress_db
• User Name: wp_foc
• Password: Pp123456

 

Step 3: Download and Extract WordPress

Install the following packages for WordPress download and unzip:

[foc@rocky9 ~]$ sudo dnf install wget unzip -y

Download wordpress with wget:

[foc@rocky9 ~]$ wget https://wordpress.org/latest.zip
--2022-10-03 10:43:52-- https://wordpress.org/latest.zip
Resolving wordpress.org (wordpress.org)... 198.143.164.252

2022-10-03 10:44:03 (1.99 MB/s) - ‘latest.zip’ saved [22772803/22772803]

Extracting from zip file:

[foc@rocky9 ~]$ unzip latest.zip

Move the wordpress directory under /var/www/html/:

[foc@rocky9 ~]$ sudo mv wordpress /var/www/html/

Authorize WordPress directory and subdirectories:

[foc@rocky9 ~]$ sudo chown -R apache:apache /var/www/html/wordpress
[foc@rocky9 ~]$ sudo chmod -R 775 /var/www/html/wordpress

Configure the SELinux context for the directory and its contents:

[foc@rocky9 ~]$ sudo semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/html/wordpress(/.*)?"
[foc@rocky9 ~]$ sudo restorecon -Rv /var/www/html/wordpress

The wp-config-sample.php file is renamed to wp-config.php:

[foc@rocky9 ~]$ sudo mv /var/www/html/wordpress/wp-config-sample.php /var/www/html/wordpress/wp-config.php

The following changes are then applied:

[foc@rocky9 ~]$ sudo vi /var/www/html/wordpress/wp-config.php

define( 'DB_NAME', 'mywordpress_db' );

/** Database username */
define( 'DB_USER', 'wp_foc' );

/** Database password */
define( 'DB_PASSWORD', 'Pp123456' );

Finally, http service is restarted:

[foc@rocky9 ~]$ sudo systemctl restart httpd

 

Step-4 Login WordPress GUI

After package installations, type http://serverip_address/wordpress into a web browser:

For example: http://192.168.122.238/wordpress/wp-admin/install.php
