分享一個Linux下，監(jiān)控MySQL主從狀態(tài)及配合企業(yè)微信機器人報警的Shell腳本

SLAVE_IP：為監(jiān)控的主機IP USER：為msyql用戶 PASSWORD：為mysql密碼 WHEREIS_MYSQL：為mysql命令路徑 WEBHOOK：為企業(yè)微信機器人Webhook地址 wx()：為企業(yè)微信機器人函數(shù) Check_Mysql_Slave()：為監(jiān)控腳本主函數(shù)

最終報警效果如下：

以上就是監(jiān)控MySQL主從狀態(tài)的shell腳本的詳細內(nèi)容，更多關(guān)于監(jiān)控MySQL主從狀態(tài)的資料請關(guān)注好吧啦網(wǎng)其它相關(guān)文章！
