 DBENGINE=MYSQL

Set DB Password

 DBRWPW="kamailiorw"

vim /etc/kamailio/kamailio.cfg

To enable use of MySQL server backend, user authentication and persistent user location, add after the first line:

#!define WITH_MYSQL
#!define WITH_AUTH
#!define WITH_USRLOCDB

To create the database structure needed by Kamailio, run:

kamdbctl create

If you changed the value of DBRWPW in kamctlrc, you must update the value of DBURL define inside kamailio.cfg.

#!define DBURL "mysql://kamailio:_NEW_DBRWPW_@localhost/kamailio"

kamctl add userid password

kamctl add omid DFcfs238r4f5

kamcmd ul.dump
