We will be installing Nagios plugins from source.
Pre-requisites
Install packages required for compiling the plugins:
$ sudo yum install -y gcc glibc glibc-common make gettext automake autoconf \ wget openssl-devel openssh-clients net-snmp net-snmp-utils epel-release \ openldap-devel mysql-devel mysql-libs fping bind-utils samba-client qstat \ lm_sensors perl-Net-SNMP
Make sure that /tmp is mounted with the exec flag:
$ sudo mount -o remount,exec /tmp
Installation
$ cd /tmp $ wget --no-check-certificate -O nagios-plugins.tar.gz https://github.com/nagios-plugins/nagios-plugins/archive/release-2.4.10.tar.gz $ tar zxf ./nagios-plugins.tar.gz $ cd /tmp/nagios-plugins-release-2.4.10/ $ ./tools/setup $ ./configure $ make $ sudo make install
Nagios plugins will be installed in /usr/local/nagios/libexec.
