### Configuring IDO

The IDO (Icinga Data Output) modules for Icinga 2 takes care of exporting all
configuration and status information into a database. The IDO database is used
by a number of projects including Icinga Web.

There is a separate module for each database backend. At present only support
for MySQL is implemented.

#### Setting up the database

First of all you have to create a database for Icinga 2:

    # mysql -u root -p

    mysql> CREATE DATABASE icinga;
    Query OK, 1 row affected (0.01 sec)

    mysql>  GRANT USAGE ON icinga.* TO 'icinga'@'localhost'
              IDENTIFIED BY 'icinga'
              WITH MAX_QUERIES_PER_HOUR 0
              MAX_CONNECTIONS_PER_HOUR 0
              MAX_UPDATES_PER_HOUR 0;

    mysql>  GRANT SELECT, INSERT, UPDATE, DELETE, DROP, CREATE VIEW, INDEX, EXECUTE
              ON icinga.* TO 'icinga'@'localhost';

    mysql>  FLUSH PRIVILEGES;

    mysql> quit

After creating the database you can import the Icinga 2 IDO schema using the
following command:

    # mysql -u root -p icinga < /path/to/icinga-src/components/db_ido_mysql/schema/mysql.sql

#### Installing the IDO module

Once you've set up your database you have to install the *icinga2-ido-mysql*
package using your distribution's package manager.

The package provides a new configuration file that is installed in
*/etc/icinga2/features-available/ido-mysql.conf*. You will need to update the
database credentials in this file.

You can enable the ido-mysql feature configuration file using *i2enfeature*:

    # i2enfeature ido-mysql
    Module 'ido-mysql' was enabled.
    Make sure to restart Icinga 2 for these changes to take effect.

After enabling the ido-mysql feature you have to restart Icinga 2:

    # /etc/init.d/icinga2 restart
