Install Nagios 3 on Ubuntu Server 12.04 with a Script


Nagios is a popular Open Source Computer System and Network Monitoring software application. With this tool, you can monitor your entire IT infrastructure, spot problems before they occur, know immediately when problem arise, and more. Here are two new scripts that you can use for easy Nagios installation on Ubuntu Server 12.04.  

  1. Copy and Paste the script below into a Text Editor  e.g  Kate
  2. Save it in the Home folder as  archive_name.sh
  3. Open Terminal
  4. Type sudo su, then press Enter
  5. Type you password, then press Enter
  6. Type  chmod  +x  archive_name.sh, then press Enter
  7. Type ./archive_name.sh, then press Enter. The installation begins
  8. You should just enter the password for user of Nagios

Nagios Script:

If you end up in the terminal you see warning:0 and error:0. Congratulation! you'll be ready to start  your network monitor.
  • Open your browser, in the address bar type "localhost / nagios /", and then press Enter
  • Type Nagios username: nagiosadmin
  • Type Nagios username password: "this is what you defined when you entered some password in the script"

      Hi Fabrizio,
      I configured nagios plugins and nrpe plugin. Also i can monitor publically available services on the test machine.

      What i understood from here is you are trying to download the nagios plugin file. i downloaded the nagios plugin and nrpe through browser and configured them.
      This will work as i did the same.

      Regards,
      nagarjun

      Hi Fabrizio,
      I made ​​a test of the links that are in the script for Nagios and Nagios Plugins download, they work perfectly. I think you should run this script with administrator privileges.

      Thank you,
