= Multi Site WordPress =
This article describes what I did to set up a multi site Wordpress system running CentOS 7 using the RPM's available from EPEL.
{{{
yum install httpd wordpress mariadb-server
systemctl enable mariadb
systemctl enable httpd
}}}

Initiate mariadb
{{{
mysql_secure_installation
}}}

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


Edit /etc/wordpress/wp-settings.php and include new salts generated here: https://api.wordpress.org/secret-key/1.1/salt/

Put in the following snippet before /* That's all, stop editing! Happy blogging. */
{{{
define( 'WP_ALLOW_MULTISITE', true );
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', 'dev.jorritsma.cc');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);
define('COOKIE_DOMAIN', $_SERVER['HTTP_HOST']);
}}}
