“Can’t connect to MySQL server on (*) (13)” Error? Centos or SE Linux? Read on.

May 12, 2008

I had the most irritating bug in PHP – or so I thought. I simply was unable to connect to the database. I spent the entire weekend recoding and simplifying until I gave up and made a simple connect statement. I kept getting the error message “Can’t connect to MySQL server on (Remote IP) (13)”.

(The “13″ is really confusing and led me down the wrong path. It is actually the result of error code 2003.)

Anyway to save you time, log into your Centos/SE Linux server and type in:

/usr/sbin/setsebool -P httpd_can_network_connect=1

This is basically a setting in SELinux that enables remote connections and is off by default. (Remind me to flay the guy who administers the network). Thanks to the OSCommerce user “ericp502″ who posted the solution.

    THANK YOU SO MUCH for posting this. I was having serious issues with exactly this same problem on RHEL5 with a remote DB. This fixed the problem.
