kamailio.cfg looks OK, can you increase the debug level to 4+, start kamailio and send me logs? May be we can find something in logs.

Thank you.

Hi Prakash,

Please paste All ERROR appearing and Warnings when you start your kamailio. What is the free memory situation on your server ?

What is your connection string in kamailio i.e. DBURL? Also make sure you have defined WITH_MYSQL on the top of kamailio.cfg to load necessary drivers.

#!define WITH_MYSQL

Thank you.

Its not a Kamailio error, it is problem with connecting to mysql server. Error 4 means No MySQL Server Running On Specified Host.

May be MySQL server is down or there is some firewall running or MySQL not listening on IP you specified.

Thank you.

Hello,

kamailio database is created with:

kamdbctl create

the host of mysql server has to be specified in kamctlrc file via DBHOST variable - kamctlrc is located in same directory as kamailio.cfg.

In kamailio.cfg, update the db_url value (or DBURL define) to reflect the mysql server host.

Cheers,
Daniel
