1. Overview
This is a module which provides MySQL connectivity for Kamailio. It
implements the DB API defined in Kamailio.
2. Dependencies
2.1. Kamailio Modules
2.2. External Libraries or Applications
2.1. Kamailio Modules
The following modules must be loaded before this module:
* No dependencies on other Kamailio modules.
2.2. External Libraries or Applications
The following libraries or applications must be installed before
running Kamailio with this module loaded:
* mysql - the development libraries forthe Mysql database. In some
Linux distributions named "libmysqlclient-dev".
3. Parameters
3.1. ping_interval (integer)
3.2. timeout_interval (integer)
3.3. auto_reconnect (integer)
3.4. insert_delayed (integer)
3.1. ping_interval (integer)
Time interval in seconds to send ping messages to MySQL server in order
to keep the connection open.
Default value is 300 (5 min).
Example 1.1. Set ping_interval parameter
...
modparam("db_mysql", "ping_interval", 600)
...
3.2. timeout_interval (integer)
Time interval (in seconds) after that an connection attempt, read or
write request is aborted. The value counts three times, as several
retries are done from the driver before it gives up.
The read timeout parameter is ignored on MySQL driver versions prior to
"5.1.12", "5.0.25" and "4.1.22". The write timeout parameter is ignored
on versions prior to "5.1.12" and "5.0.25", the "4.1" release don't
support it at all.
Default value is 2 (6 sec).
Example 1.2. Set timeout_interval parameter
...
modparam("db_mysql", "timeout_interval", 2)
...
3.3. auto_reconnect (integer)
Configure whether the module should automatically reconnect to MySQL
server if the connection was lost.
Default value is 1 (1 - on / 0 - off).
Example 1.3. Set auto_reconnect parameter
...
modparam("db_mysql", "auto_reconnect", 0)
...
3.4. insert_delayed (integer)
If set to 1, all INSERT SQL queries will be sent to MySQL server as
INSERT DELAYED.
Default value is 0 (1 - on / 0 - off).
Example 1.4. Set insert_delayed parameter
...
modparam("db_mysql", "insert_delayed", 1)
...
4. Functions
No function exported to be used from configuration file.
5. Installation
Because it dependes on an external library, the mysql module is not
compiled and installed by default. You can use one of these options.
* - edit the "Makefile" and remove "db_mysql" from "excluded_modules"
list. Then follow the standard procedure to install Kamailio: "make
all; make install".
* - from command line use: 'make all include_modules="db_mysql"; make
install include_modules="db_mysql"'.
6. Reading configuration from my.cnf
In order to take into account specific mysql client options, a my.cnf
config group can be passed using the db_url module parameter. This is
done by setting [group] in front of or instead of the host part. The
following examples are valid db_url definitions, which include a my.cnf
group:
* mysql://user:pass@[group]host:port/db
* mysql://user:pass@[group]:port/db
* mysql://user:pass@[group]/db
* mysql://[group]/db
Example 1.5. Set a my.cnf group in db_url parameter
...
modparam("usrloc", "db_url", "mysql://[kamailio]/kamailio)
...
Example 1.6. Adding a kamailio group to my.cnf
...
[kamailio]
socket = /path/to/mysql.sock
user = kamailiouser
password = kamailiopass
default-character-set = utf8
...
In addition to the given group, also the [client] section is read, in
the order given in my.cnf. So if you for example specify a socket in
both your specific group and the client group, then the value is taken
from the last one.
Example 1.7. Using [client] and specific group
...
[client]
socket = /var/run/mysql/mysqld.sock
[kamailio]
socket = /path/to/mysqld.sock
user = kamailiouser
password = kamailiopass
default-character-set = utf8
...
In the example given above, the socket /path/to/mysqld.sock is used by
Kamailio because both [kamailio] and [client] define this option, and
the latter overwrites the first.

following examples are valid db_url definitions, which include a my.cnf

[kamailio]
socket = /path/to/mysql.sock

In the example given above, the socket /path/to/mysqld.sock is used by
Kamailio because both [kamailio] and [client] define this option, and
the latter overwrites the first.
