Requirements

  • A server running CentOS 7.
  • A non-root user with sudo privilege setup on your server.

Getting Started

Update your system with the latest package versions by running the following command:

sudo yum update -y

Once your system is up-to-date, you can proceed to the next step.

Installing LAMP

Before installing WordPress itself, you will need to install the LAMP stack and other required packages on your server.

You can install all the necessary packages with the following command:

sudo yum install httpd mariadb mariadb-server php php-common php-mysql php-gd php-xml php-mbstring php-mcrypt php-xmlrpc unzip wget -y

Once installation is complete, start the Apache and MariaDB services and enable them to start at boot with the following commands:

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

Configuring MariaDB for WordPress

By default MariaDB is not secured, so you will need to secure it first. You can do this by running mysql_secure_installation script:

sudo mysql_secure_installation

Answer all the questions as shown below:

Set root password? [Y/n] n
Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] y
Remove test database and access to it? [Y/n] y
Reload privilege tables now? [Y/n] y

Once you have finished, login to MariaDB console with the following command:

mysql -u root -p

Enter your MariaDB root password and hit Enter. After login, create a database for WordPress:

MariaDB [(none)]>CREATE DATABASE wordpress;
MariaDB [(none)]>GRANT ALL PRIVILEGES on wordpress.* to 'user'@'localhost' identified by 'password';
MariaDB [(none)]>FLUSH PRIVILEGES;
MariaDB [(none)]>exit

Installing and Configuring WordPress

You can download the latest version of the WordPress source from the official website. You can get the latest version of WordPress by running the following command:

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

Once download is finished, extract the downloaded file with the following command:

tar -xzvf latest.tar.gz

Next, move the extracted files to the Apache web root directory:

sudo cp -avr wordpress/* /var/www/html/

Next, create a directory for WordPress to store uploaded files:

sudo mkdir /var/www/html/wp-content/uploads

Next, assign proper ownership and permissions to your WordPress files and folders:

sudo chown -R apache:apache /var/www/html/
sudo chmod -R 755 /var/www/html/

Next, you will need to make some changes in the WordPress main configuration file, so it can be connected with the database and user.

First, rename and edit the WordPress main configuration file:

cd /var/www/html/
sudo mv wp-config-sample.php wp-config.php
sudo nano wp-config.php

Change the DB_NAME, DB_USER, and DB_PASSWORD variables as shown below:

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

Save and close the file when you are finished.
