Installing Icinga DB on Debian

The recommended way to install Icinga DB is to use prebuilt packages from our official release repository. If the repository is not configured yet, please add it first before installing the package.

All packages we provide are signed with the following key.

Adding Icinga Package Repository

Here’s how to add the official release repository:

apt update
apt -y install apt-transport-https wget

wget -O icinga-archive-keyring.deb "https://packages.icinga.com/icinga-archive-keyring_latest+debian$(
 . /etc/os-release; echo "$VERSION_ID"
).deb"

apt install ./icinga-archive-keyring.deb

DIST=$(awk -F"[)(]+" '/VERSION=/ {print $2}' /etc/os-release); \
 echo "deb [signed-by=/usr/share/keyrings/icinga-archive-keyring.gpg] https://packages.icinga.com/debian icinga-${DIST} main" > \
 /etc/apt/sources.list.d/${DIST}-icinga.list
 echo "deb-src [signed-by=/usr/share/keyrings/icinga-archive-keyring.gpg] https://packages.icinga.com/debian icinga-${DIST} main" >> \
 /etc/apt/sources.list.d/${DIST}-icinga.list

apt update

Installing the Package

Use your distribution’s package manager to install the icingadb package as follows:

apt install icingadb

Setting up the Database

A MySQL (≥5.5), MariaDB (≥10.1), or PostgreSQL (≥9.6) database is required to run Icinga DB. Please follow the steps listed for your target database, which guide you through setting up the database and user and importing the schema.

Info

In high availability setups, all Icinga DB instances must write to the same database.

Setting up a MySQL or MariaDB Database

If you use a version of MySQL < 5.7 or MariaDB < 10.2, the following server options must be set:

innodb_file_format=barracuda
innodb_file_per_table=1
innodb_large_prefix=1

Set up a MySQL database for Icinga DB:

# mysql -u root -p

CREATE DATABASE icingadb;
CREATE USER 'icingadb'@'localhost' IDENTIFIED BY 'CHANGEME';
GRANT ALL ON icingadb.* TO 'icingadb'@'localhost';

After creating the database, import the Icinga DB schema using the following command:

mysql -u root -p icingadb </usr/share/icingadb/schema/mysql/schema.sql

Setting up a PostgreSQL Database

Set up a PostgreSQL database for Icinga DB:

# su -l postgres

createuser -P icingadb
createdb -E UTF8 --locale en_US.UTF-8 -T template0 -O icingadb icingadb
psql icingadb <<<'CREATE EXTENSION IF NOT EXISTS citext;'

The CREATE EXTENSION command requires the postgresql-contrib package.

Edit pg_hba.conf, insert the following before everything else:

local all icingadb           md5
host  all icingadb 0.0.0.0/0 md5
host  all icingadb      ::/0 md5

To apply these changes, run systemctl reload postgresql.

After creating the database, import the Icinga DB schema using the following command:

psql -U icingadb icingadb < /usr/share/icingadb/schema/pgsql/schema.sql

Configuring Icinga DB

The Icinga DB package installs its configuration file to /etc/icingadb/config.yml. Most of the settings are pre-populated for a local setup. Before running Icinga DB, adjust the Redis® and database credentials and, if necessary, the connection configuration. The configuration file explains general settings. All available settings can be found under Configuration.

Running Icinga DB

The icingadb package automatically installs the necessary systemd unit files to run Icinga DB. Please run the following command to enable and start its service:

systemctl enable --now icingadb

Installing Icinga DB Web

With Icinga 2, Redis®, Icinga DB and the database fully set up, it is now time to install Icinga DB Web, which connects to both Redis® and the database to display and work with the monitoring data.

You have completed the instructions here and can proceed to installing Icinga DB Web on Debian, which will also guide you through the setup of the Icinga Web PHP framework, which is required to run the Icinga DB web module. Below is a preview of how the interface visualizes monitoring data and also supports dark and light mode:
