vi nagios.cfg
cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
cfg_file=/usr/local/nagios/etc/objects/contactgroups.cfg
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/objects/templates.cfg
cfg_file=/usr/local/nagios/etc/objects/hosts.cfg         
cfg_file=/usr/local/nagios/etc/objects/services.cfg

and then, you can setup the contacts, hosts, services based on the demo.

After this, check the configuration: 


sudo /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
Start the nagios if there is no error: 


sudo /etc/init.d/nagios restart
