[Serusers] Mysql DB on remote host

hello group, I just started setting up Ser on a linux box (Debian). Please excuse me if my questions have been asked many times before. I have two questions here 1. when I compile from source, the mysql module is not compiled, I cannot find mysql.so anywhere. I use the latest 0.8.12 release. The daemon started okay without mysql modules. 2. after no luck with the source, I switched to Debian package. I see mysql modules are properly installed. I installed the mysql client on my Debian box, and the Mysql database on a external box, I created all tables and users successfully and I can manually access the database from command line. But when I start the Ser daemon, it would not start and still trying to look the Mysql.sock on local machine. my questions is where do you tell Ser daemon to use global my.cnf file for external database?
