Installing Icinga Web 2 from Package

A guide on how to install Icinga Web 2 from package will follow shortly.

Installing Icinga Web 2 from Source

Step 1: Getting the Source

First of all, you need to download the sources. Icinga Web 2 is available through a Git repository. You can clone this repository either via git or http protocol using the following URLs:

There is also a browsable version available at git.icinga.org. This version also offers snapshots for easy download which you can use if you do not have git present on your system.

git clone git://git.icinga.org/icingaweb2.git

Step 2: Install the Source

Choose a target directory and move Icinga Web 2 there.

mv icingaweb2 /usr/share/icingaweb2

Step 3: Configuring the Web Server

Use icingacli to generate web server configuration for either Apache or nginx.

Apache:

./bin/icingacli setup config webserver apache --document-root /usr/share/icingaweb2/public

nginx:

./bin/icingacli setup config webserver nginx --document-root /usr/share/icingaweb2/public

Step 4: Preparing Web Setup

Because both web and CLI must have access to configuration and logs, permissions will be managed using a special system group. The web server user and CLI user have to be added to this system group.

Add the system group icingaweb2 in the first place.

Fedora, RHEL, CentOS, SLES and OpenSUSE:

groupadd -r icingaweb2

Debian and Ubuntu:

addgroup --system icingaweb2

Add your web server's user to the system group icingaweb2:

Fedora, RHEL and CentOS:

usermod -a -G icingaweb2 apache

SLES and OpenSUSE:

usermod -G icingaweb2 wwwrun

Debian and Ubuntu:

usermod -a -G icingaweb2 wwwrun

Use icingacli to create the configuration directory which defaults to /etc/icingaweb2:

./bin/icingacli setup config directory

When using the web setup you are required to authenticate using a token. In order to generate a token use the icingacli:

./bin/icingacli setup token create

In case you do not remember the token you can show it using the icingacli:

./bin/icingacli setup token show

Step 5: Web Setup

Visit Icinga Web 2 in your browser and complete installation using the web setup.
