    1. Add User nagios:

root@stl-dev:~# useradd -c "Nagios User" -d /usr/local/nagios -m nagios

    1. Add group nagios:

root@stl-dev:~# groupadd nagios

    1. Change group of nagios user:

root@stl-dev:~# usermod -G nagios nagios

    1. Change owner and group of /usr/local/nagios folder:

root@stl-dev:~# chown -R nagios:nagios /usr/local/nagios


    1. Then download nrpe-2.15 or copy from other server.
    1. If you want to download please follow below link:

Download : http://sourceforge.net/projects/nagios/files/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz/download

    1. I have copied it from other server in /root/Nagios directory.
Then extract and and compile it:

To compile gcc package is neccessary if it is not in system please install it.

root@stl-dev:~# pkg install gcc-3

root@stl-dev:~# cd Nagios/

root@stl-dev:~/Nagios# gunzip nrpe-2.15.tar.gz

root@stl-dev:~/Nagios# tar xvf nrpe-2.15.tar

root@stl-dev:~/Nagios# cd nrpe-2.15

root@stl-dev:~/Nagios/nrpe-2.15# ./configure -with-ssl=/usr/sfw/ -with-ssl-lib=/usr/sfw/lib/

root@stl-dev:~/Nagios/nrpe-2.15# make all

        1. Currently there is a bug in 2.12 and 2.15 so if you try and compile it generates the following errors:
  nrpe.c: In function `get_log_facility\92:
  nrpe.c:617: error: `LOG_AUTHPRIV\92 undeclared (first use in this function)
  nrpe.c:617: error: (Each undeclared identifier is reported only once
  nrpe.c:617: error: for each function it appears in.)
  nrpe.c:619: error: `LOG_FTP\92 undeclared (first use in this function)
  *** Error code 1
  make: Fatal error: Command failed for target `nrpe\92
  Current working directory /usr/local/src/nrpe-2.12/src
  *** Error code 1
  make: Fatal error: Command failed for target `all\92
    1. To fix at this time is to comment out the code that calls these two facilities, lines 712-715, in src/nrpe.c:
 /*else if(!strcmp(varvalue,\94authpriv\94))
 log_facility=LOG_AUTHPRIV;
 else if(!strcmp(varvalue,\94ftp\94))
 log_facility=LOG_FTP;*/
    1. UPDATE: You no longer need to comment out these lines, just replace them with the following:
 else if(!strcmp(varvalue,\94authpriv\94))
 log_facility=LOG_AUTH;
 else if(!strcmp(varvalue,\94ftp\94))
 log_facility=LOG_DAEMON;
    1. Then run again make all:

root@stl-dev:~/Nagios/nrpe-2.15# make all

    1. Now you will get below output:

cd ./src/; make ; cd .. gcc -g -O2 -I/usr/include/openssl -I/usr/include -DHAVE_CONFIG_H -I ../include -I ./../include -o nrpe ./nrpe.c ./utils.c ./acl.c -L/usr/lib -lssl -lcrypto -lnsl -lsocket ./nrpe.c: In function \E2main\E2: ./nrpe.c:236:7: warning: assignment discards qualifiers from pointer target type gcc -g -O2 -I/usr/include/openssl -I/usr/include -DHAVE_CONFIG_H -I ../include -I ./../include -o check_nrpe ./check_nrpe.c ./utils.c -L/usr/lib -lssl -lcrypto -lnsl -lsocket ./check_nrpe.c: In function \E2main\E2: ./check_nrpe.c:136:7: warning: assignment discards qualifiers from pointer target type

      • Compile finished ***

If the NRPE daemon and client compiled without any errors, you can continue with the installation or upgrade process.

Read the PDF documentation (NRPE.pdf) for information on the next steps you should take to complete the installation or upgrade.

root@stl-dev:~/Nagios/nrpe-2.15# make install cd ./src/ && make install make install-plugin /usr/bin/ginstall -c -m 775 -o nagios -g nagios -d /usr/local/nagios/libexec /usr/bin/ginstall -c -m 775 -o nagios -g nagios check_nrpe /usr/local/nagios/libexec make install-daemon /usr/bin/ginstall -c -m 775 -o nagios -g nagios -d /usr/local/nagios/bin /usr/bin/ginstall -c -m 775 -o nagios -g nagios nrpe /usr/local/nagios/bin


root@stl-dev:~/Nagios/nrpe-2.15# make install-daemon-config /usr/bin/ginstall -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc /usr/bin/ginstall -c -m 644 -o nagios -g nagios sample-config/nrpe.cfg /usr/local/nagios/etc


    1. Now modify the nrpe.cfg file settings:

root@stl-dev:~/Nagios/nrpe-2.15# vim /usr/local/nagios/etc/nrpe.cfg

server_port=5666 nrpe_user=nagios nrpe_group=nagios allowed_hosts=127.0.0.1,172.17.16.3


command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10 command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20 command[check_diskspace]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p / command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200 command[check_cpu]=/usr/local/nagios/libexec/check_cpu 50 70 command[check_mem]=/usr/local/nagios/libexec/check_mem -w 25 -c 15 -f


    1. Make below entry in /etc/services file:

root@stl-dev:~/Nagios/nrpe-2.15# vim /etc/services nrpe 5666/tcp # NRPE

    1. Check nrpe service:

root@stl-dev:~/Nagios/nrpe-2.15# ps -ef | grep nrpe 

   root   571 25054   0 11:48:05 pts/3       0:00 grep nrpe
    1. Run below command:

root@stl-dev:~/Nagios/nrpe-2.15# /usr/local/nagios/bin/nrpe -n -c /usr/local/nagios/etc/nrpe.cfg -d

    1. Check again nrpe service it should be like below:

root@stl-dev:~/Nagios/nrpe-2.15# ps -ef | grep nrpe 

   root   580 25054   0 11:48:50 pts/3       0:00 grep nrpe
 nagios   578     1   0 11:48:48 ?           0:00 /usr/local/nagios/bin/nrpe -n -c /usr/local/nagios/etc/nrpe.cfg -d

    1. If nrpe is not LISTEN then please restart ther nrpe service as below:

root@stl-dev:/usr/local/nagios/libexec# ps -ef | grep nrpe 

 nagios   578     1   0 11:48:48 ?           0:00 /usr/local/nagios/bin/nrpe -n -c /usr/local/nagios/etc/nrpe.cfg -d
   root   722 25054   0 11:58:24 pts/3       0:00 grep nrpe

root@stl-dev:~/Nagios/nrpe-2.15# ps -ef | grep nrpe 

   root   571 25054   0 11:48:05 pts/3       0:00 grep nrpe

root@stl-dev:/usr/local/nagios/libexec# /usr/local/nagios/bin/nrpe -n -c /usr/local/nagios/etc/nrpe.cfg -d

root@stl-dev:/usr/local/nagios/libexec# ps -ef | grep nrpe
