Nagios Install

I knew I had a discussion on this somewhere, found it in GoogleWave. Time to rescue that... 

You don't need to go down the road of using the install script, but through reading I kept running into
dependencies that weren't included in every setup instructional I found, so I balled it all together and kept
installing Ubuntu server from scratch & running the script until I had a working Nagios install, then called
it a day. Your mileage may vary....
  1. Install Ubuntu Server (v 9.10)
    1. Install LAMP, Mail, OpenSSL, Postgres [HEY LOOK, A LAMP REFERENCE!]
  2. Username: nagios
  3. Password: [make one up]
  4. After installation and reboot, SSH to the device
    1. ifconfig to get IP from terminal if required
  5. Get Nagios Installation and Plugins Files
      1. Get the latest fromhttp://www.nagios.org/download/
      2. Copy the shortcut from the site
      3. wgethttp://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.2.0.tar.gz
      4. wgethttp://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.14.tar.gz
    2. Unpack Nagios
    3. tar xvzf [name of the nagios tar file above]
    4. Unpack plugins and install the version you have downloaded
      1. tar xvzf nagios-plugins-1.4.[xxx].tar.gz
    5. Create a file called nagiosinstall.sh and paste the following commands in the file. BE SURE TO CHANGE THE NAMES OF NAGIOS-3.2.0 and nagios-plugins-1.4.14 to be EXACTLY WHAT THE UNPACKED DIRECTORY NAMES ARE (from above).
      1. [**See part 2 for current nagiosinstall.sh script**]
  6. Upload the file to your /home/nagios directory
  7. sudo chmod +x nagiosinstall.sh
  8. ./nagiosinstall.sh
    1. Set passwords as needed
  9. Check the last bit of output, it will be the preflight check. If no errors, continue:
  10. Make nagios a service
    1. sudo ln -s /etc/init.d/nagios /etc/rcS.d/S99nagios
  11. Start Nagios
    1. sudo /etc/init.d/nagios start
  12. Browse tohttp://[IPAddress]/nagios
    1. Login with nagiosadmin and the password designated in 7.k.i
