Setup Icinga Monitoring Tool on CentOS 7 / RHEL 7
Icinga is an open source computer system and network monitoring application. It was originally created as a fork of the Nagios system monitoring application in 2009.

Icinga is attempting to get past perceived short-comings in Nagios' development process, as well as adding new features such as a modern Web 2.0 style user interface, additional database connectors (for MySQL, Oracle, and PostgreSQL), and a REST API that lets administrators integrate numerous extensions without complicated modification of the Icinga core.
Before we go ahead, lets install the required packages for Icinga.

# yum -y install wget httpd mod_ssl 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.

# useradd icinga
# groupadd icinga-cmd
# usermod -a -G icinga-cmd icinga
# usermod -a -G icinga-cmd apache
Download latest Icinga source tarball.

# cd /tmp/
# wget
# tar -zxvf /tmp/icinga-1.10.1.tar.gz
# cd /tmp/icinga-1.10.1
Compile and Install Icinga:

# ./configure --with-command-group=icinga-cmd --enable-idoutils
# 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

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)]> 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.

# /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
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.
