This article is about how Nagios+Nrpe monitors other hosts. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Monitor the running status of the machine and the Mysq host

Required package: nagios-plugins-2.1.1.tar.gz

Nrpe-2.15.tar.gz

Server side: server1.example.com 172.25.254.1

New monitoring terminal: server2.example.com 172.25.254.2

Experimental premise:

/ etc/init.d/httpd start

/ etc/init.d/nagios start

/ etc/init.d/mysqld start## if the transformation cannot be enabled, cd / var/lib/mysql/, and then rm-rf mysql.sock starts again

Chkconfig httpd on

Chkconfig mysqld on

The browser logs in to 172.25.38.6/nagios to check the service status.
