This module allows to use the unixodbc package with Kamailio. It have been tested with mysql and the odbc connector, but it should work also with other database. The auth_db module works.
For more information, see the http://www.unixodbc.org/ project web page.
To see what DB engines can be used via unixodbc, look at http://www.unixodbc.org/drivers.html.
The following modules must be loaded before this module:
No dependencies on other Kamailio modules.
Sets the ping time interval.
Default value is “300” seconds.
Example 1.1. Set the “ping_interval” parameter
...
modparam("db_unixodbc", "ping_interval", 600)
...
Turns on or off the auto_reconnect mode.
Default value is “1”, this means it is enabled.
Example 1.2. Set the “auto_reconnect” parameter
...
modparam("db_unixodbc", "auto_reconnect", 0)
...
Escape values in query using internal escape_common() function. It escapes single quote ''', double quote '"', backslash '\', and NULL characters.
You should enable this parameter if you know that the ODBC driver considers the above characters as special (for marking begin and end of a value, escape other characters ...). It prevents against SQL injection.
Default value is “0” (0 = disabled; 1 = enabled).
Example 1.3. Set the “use_escape_common” parameter
...
modparam("db_unixodbc", "use_escape_common", 1)
...
Tells if the ODBC replace query is supported by the DB odbc driver.
Default value is “1” seconds.
Prerequirement: you should first install unixodbc (or another program that implements the odbc standard, such iodbc), your database, and the right connector. Set the DSN in the odbc.ini file and the connector drivers in the odbcinst.ini file.
In the Kamailio.cfg file, add the line:
.... loadmodule "/usr/local/lib/kamailio/modules/db_unixodbc.so" ....
You should also uncomment this:
....
loadmodule "/usr/local/lib/kamailio/modules/auth.so"
loadmodule "/usr/local/lib/kamailio/modules/auth_db.so"
modparam("usrloc", "db_mode", 2)
modparam("auth_db", "calculate_ha1", yes)
modparam("auth_db", "password_column", "password")
....
and setting the DSN specified in the odbc.ini, inserting this with the url adding this line:
....
modparam("usrloc|auth_db", "db_url",
"unixodbc://kamailio:kamailiorw@localhost/my_dsn")
....
replacing my_dsn with the correct value.
HINT: if unixodbc don't want to connect to mysql server, try restarting mysql server with:
shell>safe_mysqld --user=mysql --socket=/var/lib/mysql/mysql.sock
The connector search the socket in /var/lib/mysql/mysql.sock and not in /tmp/mysql.sock
REMARK: Oracle ODBC driver doesn't support ODBC query. To disable its usage and replace the replace query by an update or insert query, use the parameter:
....
modparam("db_unixodbc", "replace_query", 0)
....
