The following error is reported when you use the icinga server to test the client script:

[Root @ mysql-server1 etc] #/usr/local/icinga/libexec/check_nrpe-H 192.168.244.146-c check_users-a 10 20

CHECK_NRPE: Received 0 bytes from daemon.  Check the remote server logs for error messages.

View the client/var/log/messages log with the following information:

Jan 18 15:50:20 mysql-server2 nrpe[3328]: Error: Request contained command arguments!Jan 18 15:50:20 mysql-server2 nrpe[3328]: Client request was invalid, bailing out...

Modify the configuration file of the client nrpe

# Vim/usr/local/icinga/etc/nrpe. cfg

dont_blame_nrpe=1

Restart the client program

[Root @ mysql-server2 etc] #/etc/init. d/icinga-nrpe restart

However, it still didn't help. Later, it was discovered that the -- enable-command-args option was not specified during the compilation of the NRPE plug-in, which caused the command line parameter to be unavailable.

You have to re-compile the client NRPE plug-in.

# Cd/usr/src/icinga-nrpe-2.14/

#./Configure -- enable-command-args

# Make all

# Make install

# Make install-plugin

# Make install-init

# Make install-xinetd

# Make install-daemon-config

After modifying the relevant parameters, test again. OK
