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 back-end. At present only support for MySQL is implemented.

Note

Icinga 2 uses the Icinga 1.x IDOUtils database schema starting with version 1.10.0.

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 < /usr/share/doc/icinga2-ido-mysql-*/schema/mysql.sql

Note

The Icinga 2 RPM packages install the schema files into /usr/share/doc/icinga2-ido-mysql-*/schema. The Icinga 2 dist tarball ships the schema files in components/db_ido_mysql/schema/.

Upgrading the database

If the database has been installed and requires an upgrade, verify the current schema version first:

# mysql -u root -p icinga -e 'SELECT version FROM icinga_dbversion;'
+---------+
| version |
+---------+
| 1.10.0  |
+---------+

Check the schema/upgrade directory for an incremental schema upgrade file, e.g. if your database schema version is 1.10.0 look for mysql-upgrade-1.11.0.sql and newer. Apply all database schema upgrade files incrementially.

# mysql -u root -p icinga < /usr/share/doc/icinga2-ido-mysql-*/schema/upgrade/mysql-upgrade-1.11.0.sql

Note

The Icinga 2 IDO module will check for the required database schema version on startup and generate an error message if not satisfied.

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
