Kamailio: Konfigurasi Awal di OpenWRT
7. Create MySQL database
To create the MySQL database, you have to use the database setup script. First edit kamctlrc file to set the database server type:
nano -w /usr/local/etc/kamailio/kamctlrc
Locate DBENGINE variable and set it to MYSQL:
DBENGINE=MYSQL
You can change other values in kamctlrc file, at least it is recommended to change the default passwords for the users to be created to connect to database.
Once you are done updating kamctlrc file, run the script to create the database used by Kamailio:
/usr/local/sbin/kamdbctl create
You can call this script without any parameter to get some help for the usage. You will be asked for the domain name Kamailio is going to serve (e.g., mysipserver.com) and the password of the 'root' MySQL user. The script will create a database named 'kamailio' containing the tables required by Kamailio. You can change the default settings in the kamctlrc file mentioned above.
The script will add two users in MySQL:
- kamailio - (with default password 'kamailiorw') - user which has full access rights to 'kamailio' database
- kamailioro - (with default password 'kamailioro') - user which has read-only access rights to 'kamailio' database
Do change the passwords for these two users to something different that the default values that come with sources.
8. Edit configuration file
To fit your requirements for the VoIP platform, you have to edit the configuration file.
/usr/local/etc/kamailio/kamailio.cfg
Follow the instruction in the comments to enable usage of MySQL. Basically you have to add several lines at the top of config file, like:
#!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB
If you changed the password for the 'kamailio' user of MySQL, you have to update the value for 'db_url' parameters.
You can browse kamailio.cfg online on GIT repository.
9. The init.d script
The init.d script can be used to start/stop the Kamailio server in a nicer way. A sample of init.d script for Kamailio is provided at:
/usr/local/src/kamailio-4.2/kamailio/pkg/kamailio/deb/debian/kamailio.init
Just copy the init file into the /etc/init.d/kamailio. Then change the permisions:
cp /usr/local/src/kamailio-4.2/kamailio/pkg/kamailio/deb/debian/kamailio.init /etc/init.d/kamailio chmod 755 /etc/init.d/kamailio
then edit the file updating the $DAEMON and $CFGFILE values:
DAEMON=/usr/local/sbin/kamailio CFGFILE=/usr/local/etc/kamailio/kamailio.cfg
You need also setup a configuration file in the /etc/default/ directory. This file can be found at:
/usr/local/src/kamailio-4.2/kamailio/pkg/kamailio/deb/debian/kamailio.default
You need to rename the file to 'kamailio' after you've copied it. Then edit this file and set RUN_KAMAILIO=yes. Edit the other options at your convenience.
Create the directory for pid file:
mkdir -p /var/run/kamailio
Default setting is to run Kamailio as user “kamailio” and group “kamailio”. For that you need to create the user:
adduser --quiet --system --group --disabled-password \
--shell /bin/false --gecos "Kamailio" \
--home /var/run/kamailio kamailio
# set ownership to /var/run/kamailio
chown kamailio:kamailio /var/run/kamailio
Then you can start/stop Kamailio using the following commands:
/etc/init.d/kamailio start /etc/init.d/kamailio stop
10. Ready to rock
Now everything is in place. You can start the VoIP service, creating new accounts and setting the phones.
A new account can be added using 'kamctl' tool via 'kamctl add <username> <password> <email>'. (or try without the email)
kamctl add test testpasswd test@mysipserver.com
If you are asked for SIP_DOMAIN environment variable do one of the following option.
1. export SIP_DOMAIN=mysipserver.com
2. edit '/root/.kamctlrc' and add: SIP_DOMAIN=mysipserver.com
