I’ve run several WPMS installs in the past, but never run into this.
So files are in /var/www/domain.com/public_html and WordPress install goes swimmingly. check the vanilla install and can update plugins, upload media, etc.
Turn on WPMS using: define(‘WP_ALLOW_MULTISITE’, true);
Jump back in and the Tools > Network Setup is there. Recommended config defines are: define(‘MULTISITE’, true); define(‘SUBDOMAIN_INSTALL’, false); define(‘DOMAIN_CURRENT_SITE’, ‘domain.com’); define(‘PATH_CURRENT_SITE’, ‘/’); define(‘SITE_ID_CURRENT_SITE’, 1); define(‘BLOG_ID_CURRENT_SITE’, 1);
and the .htaccess recommendations are also standard. Plug those in… and run bang into “Error establishing a database connection”
So something strange is happening between the standard and the WPMS install: probably something to do with the path because of the virtual host setup. I notice that these instructions are only for running in the root (with IP address as DOMAIN_CURRENT_SITE) but I’ve run WPMS in similar virtual host environments before without issues.
