zabbix监控mysql主从关系

环境

操作系统：Centos 6.* ( 双核4G、硬盘至少20G)
zabbix server :192.168.1.127
zabbix agentd :192.168.1.180
mysql slave : 192.168.1.180
mysql主从参考：http://www.jianshu.com/p/fd6ab5fd22e0

一：zabbix agentd 配置
1.mysql创建用户并赋予权限

grant select,REPLICATION CLIENT on *.* to zabbix@"localhost" identified by "zabbix";

2.刷新用户权限

flush privileges;

3.监控mysql主从同步状态脚本
vim chk_mysql-slave.sh

#!/bin/bash
/usr/local/mysql/bin/mysql   -e 'show slave status\G' |grep -E "Slave_IO_Running|Slave_SQL_Running"|awk '{print $2}'|grep -c Yes

4.获取mysql从同步post值实时变化脚本
vim chk_post.sh

#!/bin/bash
/usr/local/mysql/bin/mysql   -e 'show slave status\G' |grep -E "Read_Master_Log_Pos"|cut -d":" -f2 |sed 's/ //g'

5.给脚本添加执行权限

chmod +x chk_post.sh
chmod +x chk_mysql-slave.sh

6.在agentd配置文件末尾添加zabbix获取key值
vim /etc/zabbix/zabbix_agentd.conf

UserParameter=mysql.replication,/etc/zabbix/chk_mysql-slave.sh $1
UserParameter=mysql.post,/etc/zabbix/chk_post.sh $1

7.重启服务

/etc/init.d/zabbix-agent restart

二：zabbix server端
1.zabbix server服务器端分别获取post及状态值

/usr/local/zabbix/bin/zabbix_get -s192.168.1.180 -p10050 -k mysql.replication
/usr/local/zabbix/bin/zabbix_get -s192.168.1.180 -p10050 -k mysql.post

2.zabbix server web端
在本地新建一个txt文档，将以下模板内容粘贴并将名字及后缀更改为master-slave.xml， 导入此模板添加到zabbix agentd主机里即可
