通过mysqladmin获取mysql运行状态参数，需要登陆验证密码，这里可以将密码写在/etc/my.conf配置文件中如

[client]
host=localhost
user= 'root'

password='123.com'

[root@lamp02-salve zabbix_agentd.d]# chmod o+x /etc/zabbix/zabbix_agentd.d/check_mysql -R

[root@lamp02-salve zabbix_agentd.d]# chown zabbix.zabbix /etc/zabbix/zabbix_agentd.d/check_mysql

[root@lamp02-salve ~]# vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf #这里定义一个userparameneter子文件，将监控项key值以及脚本添加进去

zabbix web端引入模板

zabbix自带了mysql监控模板，因此只需要链接即可

上图便是我们mysql监控项，可以刚发现都对应着键值，都获取agent数据，说明监控成功
