（十一）zabbix监控mysql

1）配置脚本获取mysql的各种参数

注意：脚本中定义host

#vim /etc/zabbix/zabbix_agentd.d/mysql_status.sh
#!/bin/bash
MySQlBin=/usr/bin/mysql
MySQLAdminBin=mysqladmin
Host=localhost
if [[ $# == 1 ]];then

2）修改脚本权限

chmod +x /etc/zabbix/zabbix_agentd.d/mysql_status.sh

3）修改agent配置文件

#vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
UserParameter=mysql.status[*],/etc/zabbix/zabbix_agentd.d/mysql_status.sh $1 

4）重启服务

systemctl restart zabbix-agent 

5）修改mysql配置文件：定义脚本中命令使用的用户名和密码，这样脚本中就不需要带user和password选项了

#vim /etc/my.cnf 
[client]
user = root
password = redhat

2）server端配置

思路：定义mysql模板--->定义应用集---定义监控项---定义图集---定义触发器---->添加主机或主机关联这个模板

1）zabbix-server端zabbix_get测试获取

# zabbix_get -s 192.168.1.33 -k mysql.status[Max_connections]
151

2）key值

3）定义监控项

4）定义图形

5）验证图形
