  • To enable exception printing copy errors/local.xml.sample to errors/local.xml. But don't do it for production sites because of the mentioned security reasons.

It looks like MySQL is not running. From the server can you use the MySQL client to connect ?

If not then try starting MySQL. Service mysqld start

Let me know how you get on.
