前言:

本文主要介绍zabbix监控MySQL配置流程。

1.在mysql数据库中创建zabbix用户 用来获取数据
1
GRANT PROCESS,SUPER,REPLICATION CLIENT ON *.* TO zabbix@'%' IDENTIFIED BY 'yourpass';
2.更改zabbix配置文件

find / |grep zabbix_agentd.conf
/usr/local/etc/zabbix_agentd.conf.d
/usr/local/etc/zabbix_agentd.conf #配置文件
/usr/local/src/zabbix-3.2.3/conf/zabbix_agentd.conf   
# 添加mysql监控信息
vim /usr/local/etc/zabbix_agentd.conf
UserParameter=mysql.version,mysql -V
UserParameter=mysql.status[*],/usr/local/etc/chk_mysql.sh $1
UserParameter=mysql.ping,netstat -ntpl |grep 3306 |grep mysql |wc |awk '{print $1}'
3.在/usr/local/etc目录下创建检查脚本

# 更改脚本权限
chmod +x chk_mysql.sh
chown  zabbix:zabbix chk_mysql.sh
4.赋予zabbix用户执行netstat的权限
1
chmod +s /bin/netstat
5.重启zabbix_agentd
1
2
service zabbix_agentd stop
service zabbix_agentd start
6.进入zabbix web 后台 添加Template App MySQL模板 之后再service端检查key
1
2
zabbix_get -s 192.168.6.230 -k mysql.ping
zabbix_get -s 192.168.6.230 -k mysql.status[Com_insert]
