[Serusers] FIFO DB Can't connect to remote DB server

[Juan Priotti]

Hi all,

I moved the mysql DB from the same server it's running ser + sems and
I get this error :

Jul 15 20:51:20 server2 ser[72317]: Maxfwd module- initializing
Jul 15 20:51:20 server2 ser[72319]: new_connection(): Can't connect to
local MySQL server through socket '/tmp/mysql.sock' (2)
Jul 15 20:51:20 server2 ser[72319]: db_init(): Could not create a connection
Jul 15 20:51:20 server2 ser[72319]: ERROR: child_init(1): Error while
connecting database
Jul 15 20:51:20 server2 ser[72319]: init_mod_child(): Error while
initializing module usrloc
Jul 15 20:51:20 server2 ser[72319]: init_child failed

I've specify the address where ser has to connect to the DB
(fifo_db_url="mysql://username@password@xx.xx.xx.xx/ser"), but it
still tries to connect to a local mysql
Anybody knows why it happends? sems VM was working before moving the
DB to another server.

Thank you in advance

Juan
