一、为server.Zabbix.com添加服务模板

二、配置数据库

cd /usr/local/zabbix/etc/
vim zabbix_agentd.conf
添加配置项
UnsafeUserParameters=1		                //允许所有字符的参数传递给用户定义的参数。
UserParameter=mysql.version,mysql -V		//定义键值mysql.version，以及键值的值mysql -V
UserParameter=mysql.status[*],/usr/local/zabbix/etc/chk_mysql.sh $1			//定义键值mysql.status[*]
UserParameter=mysql.ping,mysqladmin -uroot -p123456 -P3306 -h192.168.77.111  ping | grep -c alive		             //定义键值mysql.ping，指定chk_mysql.sh脚本，使用此脚本检查mysql的运行状态，使用mysqladmin命令指定agent端的数据库连接用户密码ip地址，注意保证mysqladmin命令的链接；

编写chk_mysql.sh脚本
vim /usr/local/zabbix/etc/chk_mysql.sh
