=====Overview=====
Installation of Nagios XI can be done in two ways. 

  * Automatic
  * Manual

Both ways are pretty easy and very similar. In both cases, the procedure will verify the database, the necessary packages and other requirements. Let's start with the automatic way :)


=====Automatic=====
In order to automatically install, we can simply run the following command:


<Code:none | Nagios Install>
curl https://assets.nagios.com/downloads/nagiosxi/install.sh | sh

[  OK  ]
ndo2db was not running... could not stop
Starting ndo2db: done.
Stopping nagios: done.
Starting nagios: done.
rm: cannot remove `/usr/local/nagiosxi/var/subsys/npcd.pid': No such file or directory
NPCD was not running.
NPCD started.
Shutting down ntpd: [FAILED]
Starting ntpd: [  OK  ]
Stopping crond: [  OK  ]
Starting crond: [  OK  ]
Daemons started OK
RESULT=0
Running './Z-webroot'...

Nagios XI Installation Complete!
--------------------------------

You can access the Nagios XI web interface by visiting:
    http://172.23.4.37/nagiosxi/



</Code>

After **lengthy** installation, we have to change the permissions of the installation. 


We can connect to the server using a browser on the following address

http://IP_adress/nagiosxi

{{:nagioshome.jpg?direct&400|}}

----
  * Create new services from:
Configure -> Configuration Wizards

{{:nagiosnewservice.jpg?direct&400|}}

----
  * Review & Modify existing services from:
Configure -> Core Config Manager

{{:nagiosservicesreview.jpg?direct&400|}}

----
  * Monitor existing services
Home -> BBmap -> Services:

{{:nagiosservices.jpg?direct&400|}}



You will have to of course configure the new service (username,password) if it will be regarding database or a server. Which includes creation of a monitoring user with the correct privileges and accesses. Furthermore, once the Nagios XI is installed, you will have to reset the root password for the mysql/mariaDB database.
