Configure MySQL

~$ mysql -u root -p
~$ mysql> CREATE USER 'wordpress'@'localhost' IDENTIFIED BY 'THISpasswordSHOULDbeCHANGED';
~$ mysql> CREATE DATABASE wordpress;
~$ mysql> GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpress'@'localhost' IDENTIFIED BY 'wordpressuserpassword' WITH GRANT OPTION;

Install Wordpress

~$ sudo mkdir /opt/wordpress && sudo wget -O /opt/wordpress/wordpress-4.9.2.tar.gz https://wordpress.org/latest.tar.gz
~$ mkdir /var/www/html/website.com
~$ tar -C /var/www/html/website.com/ -zxf /opt/wordpress/wordpress-4.9.2.tar.gz
~$ sudo cp -r /var/www/html/website.com/wordpress/* /var/www/html/website.com/
~$ sudo rm -r var/www/html/website.com/wordpress/

Configure Wordpress

~$ cp /var/www/html/website.com/wp-config-sample.php /var/www/html/website.com/wp-config.php
~$ ~$ vim /var/www/html/website.com/wp-config.php
...
// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'database_name_here');

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

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

/** MySQL hostname */
define('DB_HOST', 'localhost');

it would also be a good idea to SALT your authentication and cookies. go to https://api.wordpress.org/secret-key/1.1/salt/ and it will auto generate random salts. You can change these at any time to invalidate all cookies given out forcing users to log back in.

~$ ~$ vim /var/www/html/website.com/wp-config.php
...
define('AUTH_KEY',         'mMHx%-{<+&.P~c27Yw;jQ*,bp*%W4vPF#/vo_[Q`My07j*zXj27PRumC-|4mhCV)');

HTTPD Configuration

If you've already got a site setup, you may already have httpd configured. If not, it's fairly easy.

If you're going with a subsite configuration, the virutalhost file is going to be simple and only point to the site's root directory

~$ sudo vim /etc/httpd/conf.d/website.com.conf
add:
<VirtualHost *:80>
        ServerName website.com
        ServerAdmin [email protected]
        DocumentRoot /var/www/html/website.com/
        TransferLog /var/log/httpd/website.com-access_log
        ErrorLog /var/log/httpd/website.com-error_log
</VirtualHost>
