Now we are ready to install WordPress. Let’s create a database and a user for wordpress to work with.

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

Now let’s download and install WordPress

wget http://wordpress.org/latest.tar.gz 
tar xzvf latest.tar.gz
rsync -avP ~/wordpress/ /var/www/html/
mkdir /var/www/html/wp-content/uploads
chown -R apache:apache /var/www/html/*

Next we will configure WordPress

cd /var/www/html
cp wp-config-sample.php wp-config.php

Now we need to modify the following parameters that hold our database information in “wp-config.php” file

vim wp-config.php
// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'wordpress');

/** MySQL database username */
define('DB_USER', 'wordpressuser');

/** MySQL database password */
define('DB_PASSWORD', 'password');

Now we can complete the WordPress installation through the web interface. In your web browser, navigate to your server’s domain name or public IP address and fill the required information.
