| + | ====== Install Nagios Plugin and NRPE on Redhat ====== | ||
| + | Prerequisite install | ||
| + | * xinetd | ||
| + | * openssl-devel | ||
| + | |||
| + | Redhat 3rd party libraries if added to yum can let you install nrpe via yum. However, below is an explanation of now to compile this locally. | ||
| + | |||
| + | ===== Download and Extract files ===== | ||
| + | Download and copy files to /tmp | ||
| + | * nrpe-2.15.tar.gz | ||
| + | * nagios-plugins-1.5.tar.gz | ||
| + | Extract files | ||
| + | <code bash> | ||
| + | cd /tmp | ||
| + | tar zxvf nrpe-2.15.tar.gz | ||
| + | tar zxvf nagios-plugins-1.5.tar.gz | ||
| + | </code> | ||
| + | |||
| + | ===== Create nagios Account ===== | ||
| + | <code> | ||
| + | groupadd nagios | ||
| + | useradd -d /var/log/nagios -g nagios -m -p somepassword nagios | ||
| + | date|md5sum|cut -b "1-10" | passwd --stdin nagios | ||
| + | id nagios | ||
| + | </code> | ||
| + | |||
| + | ===== Install the Nagios Plugins ===== | ||
| + | <code> | ||
| + | cd nagios-plugins-1.5 | ||
| + | ./configure | ||
| + | make | ||

| + | </code> | ||
| + | |||
| + | ===== Install the NRPE daemon ===== | ||

| + | cd nrpe-2.15 | ||
| + | ./configure | ||
| + | make all | ||
| + | make install-plugin | ||
| + | make install-daemon | ||
| + | make install-daemon-config | ||
| + | make install-xinetd | ||
| + | |||
| + | chown -R nagios:nagios /usr/local/nagios | ||
| + | </code> | ||
| + | |||
| + | Update nagios server IP address here. Included additional IP separated by spaces. | ||
| + | <code> | ||
| + | grep only /etc/xinetd.d/nrpe | ||
| + | </code> | ||
| + | |||
| + | Use the following example to replace easily! | ||
| + | <code> | ||
| + | sed -i 's@only_from = 127.0.0.1@only_from = 127.0.0.1 10.50.60.0/24 204.67.86.0/24@' /etc/xinetd.d/nrpe | ||
| + | </code> | ||
| + | |||
| + | Add the NRPE daemon to services | ||
| + | <code> | ||
| + | echo "nrpe 5666/tcp # NRPE" >> /etc/services | ||
| + | service xinetd restart | ||
| + | </code> | ||
| + | |||
| + | |||
| + | ===== Test NRPE daemon ===== | ||
| + | Check for Listening port | ||
| + | <code> | ||
| + | netstat -at | grep nrpe | ||
| + | </code> | ||
| + | should have output as | ||
| + | <code> | ||
| + | tcp 0 0 *:nrpe *:* LISTEN | ||
| + | </code> | ||
| + | |||
| + | Run the call to service | ||
| + | <code> | ||
| + | /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 | ||
| + | </code> | ||
| + | Should return **NRPE v2.15** | ||
