Question

我试图在localhost上检查mysql和tomcat。基本上我需要检查端口以查看应用程序正在侦听。我安装了nrpe和nagios插件我试图使用nrpe来检查localhost上的mysql，但是nagios显示了这个错误：NRPE：命令check_mysql未定义

请问好吗？

您需要为NRPE定义check_mysql命令定义。

编辑你的nrpe.cfg。

vim /etc/nagios/nrpe.cfg

为check_mysql添加一个指向check_mysql插件路径的命令条目：

command[check_mysql]=/usr/lib64/nagios/plugins/check_mysql

重启nrpe：

service nrpe restart
