WPMS database error on install

I’ve run several WPMS installs in the past, but never run into this.


So files are in /var/www/ 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’, ‘’); 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.

Help appreciated!

Here’s some info. from the <a href=“”>WordPress Codex</a>:<br/><h2>Apache Virtual Hosts and Mod Rewrite</h2>To [allow] <strong>mod_rewrite</strong> to work within an Apache Virtual host [make sure you enable it, first; and] you may need to set some options on the DocumentRoot.<br/><br/><code><VirtualHost *:80><br/> DocumentRoot /var/www/vhosts/wordpress<br/> <Directory /var/www/vhosts/wordpress><br/>  AllowOverride Fileinfo Options<br/></Directory></code><br/><br/>In some instances, you will need to add <strong>All</strong> to your <strong>AllowOverride</strong> for all .htaccess rules to be honored.

I have a hunch that the way you’re structuring your directories what’s causing you problems… lemme look into it some more.

Add these in: <br> <br>define(‘WP_DEBUG’, true); <br>define(‘WP_DEBUG_LOG’, true); <br>define(‘WP_DEBUG_DISPLAY’, true); <br>define(‘SAVEQUERIES’, true); <br> <br>Reload the wordpress site, do you see any errors?
