nrpe：命令mysql_check未定義

Question

我想檢查本地主機上的mysql和tomcat。 基本上我需要檢查端口以查看應用程序正在偵聽。 我有NRPE以及Nagios的插件安裝 我試圖使用NRPE檢查本地主機上的MySQL，但是Nagios會顯示此錯誤：NRPE：命令check_mysql沒有定義

任何想法嗎？

您需要爲NRPE定義一個check_mysql命令定義。

編輯您的nrpe.cfg。

vim /etc/nagios/nrpe.cfg 

爲check_mysql指向添加一個命令輸入到check_mysql插件的路徑：

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

重新啓動NRPE：

service nrpe restart
