1、zabbix添加mysql的监控模板(temple-app-mysql)之后，还需要在客户端添加key去取值。

2、编写脚本，获取mysql的各种状态值。可以固定一个目录，专门存放监控脚本。比如/usr/local/zabbix/scripts/chk_mysql.sh

#!/bin/bash

3、修改zabbix的配置文件/usr/local/zabbix-agentd/etc/zabbix_agentd.conf，添加

#获取mysql版本

UserParameter=mysql.version,mysql -V

##获取mysql性能指标,这个是上面定义好的脚本

UserParameter=mysql.status[*],bash /alidata/zabbix-agentd/scripts/chk_mysql.sh $1

##获取mysql运行状态

UserParameter=mysql.ping,/alidata/mysql/bin/mysqladmin -uroot -pliujinWANG1985 -P3306 -h127.0.0.1 ping | grep -c alive

UserParameter=mysql.process,/alidata/mysql/bin/mysql -uroot -pliujinWANG1985 -P3306 -h127.0.0.1 -e "show processlist" 2>/dev/null|wc -l

4、重启zabbix的客户端
