After setting up Moog, I started seeing:
<pre>
MySQL generated an error. The current user is

    REMOTE_HOST = 
    HTTP_GET_VARS:

The error message is:

We are using sockets here, the port is not open to the network, though it is open to localhost and to moog from moog.
<pre>
[root@moog moog.key]# telnet localhost 3306

telnet: connect to address ::1: Connection refused

<h2>Solution</h2>
It looks like the problem was that some of the databases
for the other websites are not yet present:

<code>/export/home1/tmp/php.err</code> says:

This will go away when the entire website is updated.
