NRPE Agent Configuration on Client Nodes (Linux Machine)

By -

NRPE Agent Configuration:

Steps to be followed on client Node are mentioned below:

Step 1. Pre-requisite software:

            yum install -y gcc glibc glibc-common openssl openssl-devel perl wget

            cd /tmp

            wget --no-check-certificate -O nrpe.tar.gz  

            https://github.com/NagiosEnterprises/nrpe/archive/nrpe-3.2.1.tar.gz

Step 2. nrpe agent installation on the client node

            tar xzf nrpe.tar.gz

            cd /tmp/nrpe-nrpe-3.2.1/

            ./configure --enable-command-args                                 #Configure NRPE Agent

            make all                                                                            #Compalie NRPE Agent

            make install-groups-users                                                # Install NRPR Agent

            make install

            make install-config

Step 3. Service file configuration

            echo >> /etc/services                                                         # service file configuration

            echo '# Nagios services' >> /etc/services

            echo 'nrpe    5666/tcp' >> /etc/services

            make install-init

            systemctl enable nrpe.service

            vi /usr/local/nagios/etc/nrpe.cfg

            allowed_hosts=127.0.0.1,host_ip                                         #add host server id address

            systemctl start nrpe.service

            /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1

Step 4. Creating configuration file

            NRPE Agent -Adding Linux clients –Nagios server editing 

            vi  /usr/local/nagios/etc/nagios.cfg    

#Add the below line into the configuration file

            cfg_file=/usr/local/nagios/etc/objects/client.cfg

            cd /usr/local/nagios/etc/objects

            cp  localhost.cfg   client.cfg

            sudo chown nagios:nagios client.cfg

            sudo vi client.cfg

#Add IP address of client node in client.cfg file along with replacing host_name with client_name in the whole file from localhost and Delete or comment out the Host Group

            service nagios restart                                                            #Restart the server

For example, you prepared an application or a machine but it's the hardware or just a view. What makes it run is its software (Soul of any Machines, Application, or Website). Now, what is Software? Software is nothing but a collection of data or instructions that tell the Application (Computer, Machines, Hardware, Website, etc...) how to work. Software Life Cycle..! Okay so now you know what is software, but every software is first needed to be developed according to the requirement, and then it goes for testing if testing is failed it again goes for the redevelopment once the testing process is tested successfully then i
