Install Icinga Monitoring Tool on Fedora 22 / 21


Icinga Logo

Icinga is a fork of famous Ngaios monitoring tool, it is very compatible with Nagios and can bea integrated with Nagios plugins. Icinga is very similar to Nagios, so you would find no difficult in moving to Icinga. Icinga is one step ahead on multiple factors, the import factor is advanced reporting using we based jasper reports, the most improved web interface and its comes as virtual appliance.

This post will help you to setup Icinga on Fedora 22 / 21


Before we go ahead, lets install the required packages for Icinga.

# dnf -y install wget cmake httpd mod_ssl gcc-c++ gd gd-devel mariadb-server php-mysql php-xmlrpc gcc mariadb libdbi libdbi-devel libdbi-drivers libdbi-dbd-mysql

Disable SELinux.

# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

Reboot once done.

Create icinga user and icinga-cmd group (allowing the external commands to be executed through the web interface) , add icinga and apache user to the part of icinga-cmd group.

# groupadd icinga
# groupadd icingacmd
# useradd -c "icinga" -s /sbin/nologin -G icingacmd -g icinga icinga
# usermod -a -G icingacmd apache

Download latest Icinga source tarball.

# cd /tmp/
# wget -O icinga2.tar.gz 
# tar -zxvf icinga2.tar.gz
# cd /tmp/icinga2-2.3.5/

Compile and Install Icinga:

# mkdir build && cd build
# make all
# make install
# make install-init
# make install-config
# make install-commandmode
# make install-webconf
# make install-idoutils

Configure Icinga:

Sample configuration files have now been installed in the /usr/local/icinga/etc/ directory. These sample files should work fine for getting started with Icinga. You’ll need to make just one change before you proceed. Edit the /usr/local/icinga/etc/objects/contacts.cfg config file with your favorite editor and change the email address associated with the nagiosadmin contact definition to the address you’d like to use for receiving alerts.

# vi /usr/local/icinga/etc/objects/contacts.cfg

Change the Email address field to receive the notification.

email                           icinga@localhost


email                           [email protected]

Move sample idoutils configuration files to Icinga base directory.

# cd /usr/local/icinga/etc/
# mv idomod.cfg-sample idomod.cfg
# mv ido2db.cfg-sample ido2db.cfg
# cd modules/
# mv idoutils.cfg-sample idoutils.cfg

Create database for idoutils:

# systemctl start mariadb.service
# mysql -u root -p
MariaDB [(none)]> CREATE DATABASE icinga;
MariaDB [(none)]> GRANT SELECT, INSERT, UPDATE, DELETE, DROP, CREATE VIEW, INDEX, EXECUTE ON icinga.* TO 'icinga'@'localhost' IDENTIFIED BY 'icinga';
MariaDB [(none)]> quit

Import Database.

mysql -u root -p icinga < /tmp/icinga-1.10.1/module/idoutils/db/mysql/mysql.sql

Configure Web Interface:

Create a icingaadmin account for logging into the Icinga web interface. Remember the password that you assign to this user – you’ll need it later.

# htpasswd -c /usr/local/icinga/etc/htpasswd.users icingaadmin

Restart Apache to make the new settings take effect.

systemctl restart httpd.service

Download and Install Nagios Plugins:

Download Nagios Plugins to /tmp directory.

# cd /tmp
# wget
# tar -zxvf /tmp/nagios-plugins-2.0.3.tar.gz
# cd /tmp/nagios-plugins-2.0.3/

Compile and install the plugins.

# ./configure --prefix=/usr/local/icinga --with-cgiurl=/icinga/cgi-bin --with-nagios-user=icinga --with-nagios-group=icinga
# make
# make install

Starting Icinga:

Verify the sample Icinga configuration files.

# /usr/local/icinga/bin/icinga -v /usr/local/icinga/etc/icinga.cfg

If there are no errors, start Nagios and Idoutils.

# chkconfig --add icinga
# chkconfig --add ido2db
# /etc/init.d/icinga start
# /etc/init.d/ido2db start

Start Icinga and Idoutils on system startup.

# chkconfig ido2db on
# chkconfig icinga on
# systemctl enable httpd.service
# systemctl enable mariadb.service

Configure firewall to access Icinga portal.

#  firewall-cmd --add-service=http
# firewall-cmd --permanent --add-service=http
# systemctl restart firewalld

Access Web Interface:

Now access Icinga web interface using the following URL. You’ll be prompted for the username (icingaadmin) and password you specified earlier.
