Installing WordPress on CentOS 7

WordPress is a popular content management system (CMS) and blogging platform that allows users to easily create and manage websites. It is built on PHP and uses a MySQL or MariaDB database to store content. WordPress provides a user-friendly interface and a wide range of themes and plugins, making it highly customizable and flexible for any type of website.

Here is a step-by-step guide to install WordPress on a CentOS 7 server:

Step 1: Update System Packages

Before installing any software, it is recommended to update the system packages to their latest versions. This can be done using the following commands:

  sudo yum update sudo yum upgrade  

Step 2: Install LAMP Stack

WordPress requires a LAMP stack (Linux, Apache, MySQL/MariaDB, PHP) to run. Install the necessary components using the following command:

  sudo yum install httpd mariadb-server php php-mysql  

Step 3: Start and Enable Services

Start and enable Apache and MariaDB services on the server:

  sudo systemctl start httpd sudo systemctl enable httpd sudo systemctl start mariadb sudo systemctl enable mariadb  

Step 4: Secure MariaDB Installation

Secure the MariaDB installation by running the mysql_secure_installation script:

  sudo mysql_secure_installation  

Follow the instructions to set a root password, remove anonymous users, disallow remote root login, and remove test databases.

Step 5: Create a Database for WordPress

Create a new database and user for WordPress:

  sudo mysql -u root -p CREATE DATABASE wordpress; CREATE USER 'wordpressuser'@'localhost' IDENTIFIED BY 'password'; GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpressuser'@'localhost'; FLUSH PRIVILEGES; EXIT;  

Replace 'password' with a strong password of your choice.

Step 6: Download and Configure WordPress

Download and extract the latest WordPress package:

  cd /var/www/html sudo wget https://wordpress.org/latest.tar.gz sudo tar -xvzf latest.tar.gz sudo mv wordpress/* . sudo chown -R apache:apache /var/www/html  

Step 7: Configure WordPress Database Settings

Rename the sample configuration file and provide the database details:

  sudo mv wp-config-sample.php wp-config.php sudo vi wp-config.php  

Edit the following lines:

  define('DB_NAME', 'wordpress'); define('DB_USER', 'wordpressuser'); define('DB_PASSWORD', 'password');  

Replace 'password' with the password you set for the database user.

Step 8: Configure Apache Virtual Host

Create a virtual host configuration file for WordPress:

  sudo vi /etc/httpd/conf.d/wordpress.conf  

Add the following lines:

     ServerName your-domain.com   DocumentRoot /var/www/html/        AllowOverride All      

Replace 'your-domain.com' with your actual domain name or server IP address.

Step 9: Restart Apache Service

Restart the Apache service to apply the changes:

  sudo systemctl restart httpd  

Step 10: Complete WordPress Installation

Open a web browser and navigate to your domain or server IP address. You will be greeted with the WordPress installation page. Follow the on-screen instructions to complete the installation by providing a site title, username, password, and email.

That's it! You have successfully installed WordPress on CentOS 7.
