Installing Icinga on Scientific Linux 6.4

Icinga is a well-known server or network monitoring that runs in many Unix/Linux distribution. Server/Network monitoring is an essential part of Network Operations Center because by monitoring network engineers can always get the feedback and status from network and production servers. This is a simple documentation of Icinga installation in Scientific Linux 6.4 server. ###Getting started Before we install icinga, it best to keep our system updated.

Install icinga and the dependencies.

# yum --enablerepo=rpmforge install icinga icinga-gui icinga-doc icinga-idoutils-libdbi-mysql
# yum install mysql-server mysql-client libdbi libdbi-devel libdbi-drivers libdbi-dbd-mysql

Create database for icinga.

# mysql -uroot -p
mysql> CREATE DATABASE icinga;
mysql> GRANT USAGE ON icinga.* TO 'icinga'@'localhost' IDENTIFIED BY 'icinga' WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0;
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, DROP, CREATE VIEW, INDEX, EXECUTE ON icinga.* TO 'icinga'@'localhost';
mysql> FLUSH PRIVILEGES;
mysql> quit

After we create database for icinga, import the database template to icinga database.

# mysql -uicinga -p icinga < /usr/share/doc/icinga-idoutils-libdbi-mysql-1.8.4/db/mysql/mysql.sql

Don’t forget to disable Selinux if you do not use it. Insert database credential into file ido2db.cfg.

# vi /etc/icinga/ido2db.cfg

db_name=icinga
db_user=icinga
db_pass=icinga

Now we can start icinga and don’t forget to start ido2db too.

# /etc/rc.d/init.d/ido2db start
# /etc/rc.d/init.d/icinga start
# /etc/rc.d/init.d/httpd restart
# chkconfig ido2db on
# chkconfig icinga on

Add icinga user or update password of existing one using command below.

# htpasswd /etc/icinga/passwd youradmin

###Testing Icinga We can now access icinga via this URL on browser.

http://yourdomain/icinga

Review the status and fix errors if any. Now you have your own icinga up and running. Congrats!
