How to Install WordPress with Apache on CentOS 8

WordPress is the popular and widely used blogging and content management system in the world. PHP processing and MySQL/MariaDB database are used as a backend in WordPress. It is simplest way to create a Blog, Portfolio Website, webshop etc. In this tutorial, we will show you how to install WordPress with Apache on CentOS 8.

Prerequisites#

We are going to use LAMP (Linux, Apache, MariaDB, and PHP) stack with Apache as web server. Make sure that you met the following prerequisites before start installation process:

• CentOS server with a non-root user with sudo privileges.
• Apache must installed and configured, as shown in this tutorial.
• Your domain name should pointing to your server IP address.
• An SSL certificate installed for your domain. You can install a free Let’s Encrypt SSL certificate as shown in this tutorial.

Step 1 – Create database and Grant Permissions#

WordPress is using MySQL-based database to store the data. So first of all we need to create a MariaDB database, MariaDB user and grant permission. If you system don’t have installed MariaDB, you can follow How to Install MariaDB on CentOS 8 tutorial.

At first, log in to MariaDB shell using below command:

 mariadb -u root -p

It will prompt you to enter password for the root user. You will be logged in on entering correct password.

Type the below command to create a new MariaDB database for your WordPress:

CREATE DATABASE wordpress DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;

Now you have to create a new MariaDB user by issuing below command:

GRANT ALL ON wordpress.* TO 'wordpressuser'@'localhost' IDENTIFIED BY 'enter-strong-password';

Need to flush the database so changes can reflact in MySQL, type:

FLUSH PRIVILEGES;

Finally, exist from MySQL shell by typing:

EXIT;

Step 2 – Installing Additional PHP Extensions#

To install all the required modules run below command in the terminal:

sudo apt install php-curl php-gd php-intl php-mbstring php-soap php-xml php-xmlrpc php-zip

Note: PHP packages set requirements depends on WordPress plugin. Some may require additional PHP packages to be installed. Check your plugin documentation to discover its PHP requirements.

You should restart the Apache service to load these new extensions in the next section by issuing below command:

sudo systemctl restart httpd

Step 3 – Download and Setup WordPress#

First, navigate to /tmp directory using below command:

cd /tmp

Now download the latest WordPress setup from the WordPress download page using using below wget command:

wget https://wordpress.org/latest.tar.gz

Once the download is completed, extract the downloaded files using below command:

tar xzvf latest.tar.gz

After that, create the configuration file for WordPress using below command:

cp /tmp/wordpress/wp-config-sample.php /tmp/wordpress/wp-config.php

Then copy all the files to example.com directory using below command:

sudo cp -a /tmp/wordpress/. /var/www/example.com

You need to set the correct permissions so web server can the site’s files and directories. To change the ownership of example.com directory use following chown command:

sudo chown -R www-data:www-data /var/www/example.com

Step 4 – Configure Apache#

You should have installed Apache with SSL certificate installed on your CentOS machine. We will create a new virtual host for our WordPress instance.

Open your text editor and create the following file:

sudo nano /etc/apache/conf.d/example.com.conf

<VirtualHost *:80>
  ServerName example.com
  ServerAlias www.example.com

  Redirect permanent / https://example.com/
</VirtualHost>

<VirtualHost *:443>
  ServerName example.com
  ServerAlias www.example.com

  Protocols h2 http:/1.1

  <If "%{HTTP_HOST} == 'www.example.com'">
    Redirect permanent / https://example.com/
  </If>

  DirectoryIndex index.html index.php
  DocumentRoot /var/www/example.com

  ErrorLog ${APACHE_LOG_DIR}/example.com-error.log
  CustomLog ${APACHE_LOG_DIR}/example.com-access.log combined

  SSLEngine On
  SSLCertificateFile /etc/letsencrypt/live/example.com/cert.pem
  SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
  SSLCertificateChainFile /etc/letsencrypt/live/example.com/chain.pem

  <Directory /var/www/example.com>
      Options FollowSymLinks
      AllowOverride All
      Require all granted
  </Directory>

</VirtualHost>

Note : You should replace your real domain name with example.com and set correct SSL certificates path.

After that restart the Apache service by below command:

sudo systemctl restart httpd
