How to Install the Nagios Plugins

Prerequisites

Before starting, ensure you have:

1. Server root login credentials.

Step-1:
Create a directory for storing the downloads, if you don't already have one.

  mkdir ~/downloads
   cd ~/downloads

Step-2:

Download the source code tarball of the Nagios plugins (visit http://www.nagios.org/downloads/ for links to the latest versions).

At the time of writing, the latest stable version of the Nagios plugins was 2.1.1.

  wget http://nagios-plugins.org/download/nagios-plugins-2.2.1.tar.gz

Extract the Nagios plugins source code tarball.

  tar xzf nagios-plugins-2.2.1.tar.gz
  cd nagios-plugins-2.2.1

Note: on some systems, you will have to run the extract this way:

 gunzip -c nagios-plugins-2.2.1.tar.gz | tar xf -

Step-3:

Compile and install the plugins.

  ./configure
  make
  make install

Step-4:

Depending on the version of the plugins, the permissions on the plugin directory and the plugins may need to be fixed at this point. If so run the following commands:

  useradd nagios
  groupadd nagios
  usermod -a -G nagios nagios
  chown nagios.nagios /usr/local/nagios
  chown -R nagios.nagios /usr/local/nagios/libexe
