Installing Icinga 2 with MySQL on FreeBSD

Icinga 2 and MySQL are both in FreeBSD's ports tree, so installing them via ports or packages is not too hard but you need to configure both afterwards.

This tutorial expects a clean FreeBSD installation, so please check if all steps are applicable to your installation. Where possible, I will install from packages but installation from ports should be similar.

Install Icinga 2 and MySQL packages and enable both at boot time

The following will install Icinga 2 and MySQL Server 5.6, and enable starting of them via /etc/rc.conf.

# pkg install icinga2 mysql56-server
# sysrc icinga2_enable=yes
# sysrc mysql_enable=yes

Start the MySQL Server, but don't start Icinga 2, yet.

# service mysql-server start

Secure the MySQL installation

# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL [21/9199]
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!


By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
... Success!

Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
... Success!

By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
... Success!




All done! If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!


Cleaning up...

Make sure to remember the root password for the MySQL database, you will need it later.

Create database schema for Icinga 2

In order for Icinga 2 to write to the database you need to create a database schema.

# mysql -p -u root # Enter the root password for the database
mysql> CREATE DATABASE icinga;
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, DROP, CREATE VIEW, INDEX, EXECUTE ON icinga.* TO 'icinga'@'localhost' IDENTIFIED BY 'icinga';
mysql> connect icinga;
mysql> source /usr/local/share/icinga2-ido-mysql/schema/mysql.sql;

Of course I don't need to tell you to use a real password, do I? :-)

Enabling Icinga 2 features and start Icinga 2

The last thing to do is enabling the "ido-mysql" feature in Icinga 2. While we're here, we can also enable other useful features.

# icinga2 feature enable command ido-mysql livestatus perfdata statusdata
# service icinga2 start

That's it! If everything went well you should not see any errors in /var/log/icinga2/icinga2.log

In the ´╗┐next part will be about using Icinga Web 2 together with Icinga 2 on FreeBSD.
