MySQL常规巡检
一、巡检脚本
巡检脚本包括三个文件inspection.conf、inspection_mysql.sh、mysqltuner.pl
bash>ll
-rw-r--r-- 1 root root 994 Nov 1 16:33 inspection.conf
-rwxr-xr-x 1 root root 39221 Nov 1 15:26 inspection_mysql_v4.sh
-rwxr-xr-x 1 root root 219803 Nov 1 11:32 mysqltuner.pl二、下载巡检脚本
- 下载地址：
三、脚本执行说明
1、inspection.conf 使用说明
使用说明：配置mysql登录账号信息以及mysql的标准配置

inspection_mysql.sh
脚本简述 :主脚本通过读取inspection.conf 配置文件来执行，调用perl来执行 mysqltuner.pl来提供优化建议
