yum install epel-release

If you are using RHEL you need enable the optional repository and then install the EPEL rpm package.

In order to correctly manage your repository, please follow these instructions.

Installing Icinga Web 2

You can install Icinga Web 2 by using your distribution's package manager to install the icingaweb2 package. Below is a list with examples for various distributions. The additional package icingacli is necessary on RPM based systems for being able to follow further steps in this guide. In DEB based systems, the icingacli binary is included in the icingaweb2 package.

Debian and Ubuntu:

apt-get install icingaweb2

RHEL, CentOS and Fedora:

yum install icingaweb2 icingacli

If you have SELinux enabled, the package icingaweb2-selinux is also required. For RHEL/CentOS please read the package repositories notes.

SLES and openSUSE:

zypper install icingaweb2 icingacli

Alpine Linux:

apk add icingaweb2

For Alpine Linux please read the package repositories notes.

Preparing Web Setup

You can set up Icinga Web 2 quickly and easily with the Icinga Web 2 setup wizard which is available the first time you visit Icinga Web 2 in your browser. When using the web setup you are required to authenticate using a token. In order to generate a token use the icingacli:

icingacli setup token create

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

icingacli setup token show

Preparing Web Setup on Debian

On Debian, you need to manually create a database and a database user prior to starting the web wizard. This is due to local security restrictions whereas the web wizard cannot create a database/user through a local unix domain socket.

MariaDB [mysql]> CREATE DATABASE icingaweb2;

MariaDB [mysql]> GRANT ALL ON icingaweb2.* TO icingaweb2@localhost IDENTIFIED BY 'CHANGEME';

You may also create a separate administrative account with all privileges instead.

Note: This is only required if you are using a local database as authentication type.

Starting Web Setup

Finally visit Icinga Web 2 in your browser to access the setup wizard and complete the installation: /icingaweb2/setup.

Note for Debian

Use the same database, user and password details created above when asked.

The setup wizard automatically detects the required packages. In case one of them is missing, e.g. a PHP module, please install the package, restart your webserver and reload the setup page.

If you have SELinux enabled, please ensure to either have the selinux package for Icinga Web 2 installed, or disable it.
