I have configured an Ubuntu webserver with Nginx + PHP5-FPM. I have created a chrooted environment (using jailkit) that I'm tossing my developers into, from where they can develop their test applications.
Chroot jail: /home/jail
Nginx and PHP5-FPM run outside the chroot, but are configured to function with websites within the chrooted environment.
So far, Nginx and PHP5-FPM are serving up files without issue, except for the following: When attempting to connect to MySQL, we receive this error: SQLSTATE[HY000]  Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'
Now, I believe the issue is due to the non-chrooted php.ini referencing mysqld.sock outside of the chroot environment (it's actually using the MySQL default setting currently).
My question is, how can I configure PHP to access MySQL via loopback or similar? (Found that as a suggestion in a google result, but without any instructions)
Or if I'm missing some other obvious setting, let me know. If there's an option of creating a hardlink (that would remain available even if mysql is restarted), that would be handy as well.
