MySQL

This module is used to make the connection between Yate and a MySQL database.

When using this module for storing CDRs, also read [call.cdr] section in Register.

Check if module is loaded

Note: Check if module MySQL is loaded. It is required to be loaded so that Yate can connect to the database defined in mysqldb.conf.

Verify module loading when starting Yate

When Yate starts you can see a list of modules that are loaded. If MySQL does not appear, you must install the devel packages for MySQL.

./run -vvvvv -CDo
..........
Loaded module MySQL based on 5.1.42
.......

Verify module loading from rmanager

Another way to check if module is loaded is from telnet, use command status check if mysqldb is in the list:

 %%+status                                                             
 ...............
name=mysqldb,type=database,format=Total|Failed|Errors|AvgExecTime;conns=0,failed=0
............
%%-status

Or simply type after command status the name of the module like this:

status mysqldb
%%+status:mysqldb
name=mysqldb,type=database,format=Total|Failed|Errors|AvgExecTime;conns=0,failed=0
%%-status

If line name=mysqldb,type=database.... don't appear in the list that means that module is not loaded.

Solutions

• A reason that the module is not loaded may be that you don't have the devel packages installed.

Install devel packages. Then run ./configure and make in Yate's sources.

• Another reason could be that the module is not listed in file yate.conf. If parameter modload is disabled, then you have to check in [modules] section that module is enabled.

yate.conf

[general]
modload=no

[modules]
mysqldb.yate=yes

Configuration file

The configuration file is mysqldb.conf. It is found in directory conf.d where Yate sources are.
The file must be renamed from mysqldb.conf.sample into mysqldb.conf.

This file has the general section that holds the common settings to all connections.
The other sections in this file will describe each database connection.
The section name written between [], is the account name of the connection that can be used in other configuration files.

There can be multiple connections to different databases.

mysqldb.conf

[general]
; This section is special - holds settings common to all connections

; priority: int: Handler priority
;priority=100


; Each other section in this file describes a database connection

;[default]
; The section name is used as the database connection name

; timeout: int: Query timeout in milliseconds - will be rounded to seconds
;timeout=10000

; initretry: int: Interval (in seconds) to retry creating failed connections. Setting it to 0 will disable retrying.
;initretry=10

; host: string: MySQL server to connect to, defaults to local
;host=

; port: int: Port on which the server is listening for connections
;port=0

; database: string: Name of the database to use in queries
;database=yate

; user: string: Username to use to access the database
;user=mysql

; password: string: Password to authenticate the user to the database server
;password=

; socket: string: UNIX socket to use for local connections
;socket=

; compress: bool: Enable use of compression protocol
;compress=disable 

; encoding: string: Character set encoding used to communicate with the server
; If not set or empty will use the default for your system
; This setting is not available on older MySQL client libraries
;encoding=

; poolsize: int: Number of connections to establish for this account
; If not set or empty, it will create only one connection
; Minimum number of connections is 1, maximum is 10
;poolsize=1

Example

This is how we create a new connection to a MySQL database.

mysqldb.conf

[yatetest]
database=yate
user=mysql
password=yate

If we need to store CDRs, we will have to use register.conf file.

In this file, we are going to set into general section the account name of the database so that Yate will know which connection to make.

register.conf

[general]
account=yatetest
