上次Zabbix添加了监控MySQL性能，因此此次在其基础上添加主从监控，文章过程中不在介绍MySQL5.6版本相关细节处理，具体可以参考上次文章：

# 1. Zabbix添加自定义监控流程 #

1.  Zabbix agentd添加自定义key；
2.  自定义key调用的是获取监控数据源脚本等；
3.  添加Zabbix主机数据源模板，主机链接模板;

# 2. 具体步骤 #

## 1. 编写监控mysql主从脚本 ##

`vim /usr/local/zabbix/shell/check_mysql_slave.sh`

#!/usr/bin/env bash
    #Create by zijin 2014.09.28
    ##Need "grant REPLICATION CLIENT on *.* to zabbix_select@localhost identified by 'zabbix'"
    #Mysql5.6
    # mysql_config_editor set --login-path=local --host=localhost --user=zabbix_select -p
    MYSQL_SOCK="/tmp/mysql.sock" 
    MYSQL_PWD="zabbix"
    MYSQL="/usr/local/mysql/bin/mysql"
    MYSQL_ADMIN="${MYSQL}admin"
    ARGS=1 
    if [ $# -ne "$ARGS" ];then 
        echo "Please input one arguement:" 
    fi 
    case $1 in 
            Slave_Running) 
                    slave_is=($(sudo ${MYSQL} --login-path=local -S $MYSQL_SOCK -e "show slave status\G"|egrep "\bSlave_.*_Running\b"|awk '{print $2}'))
                    if [ "${slave_is[0]}" = "Yes" -a "${slave_is[1]}" = "Yes" ];then
                         result="1"
                    else
                         result="0"
                    fi
                    echo $result
            ;;
            Seconds_Behind)
                    result=$(sudo ${MYSQL} --login-path=local -S $MYSQL_SOCK -e "show slave status\G"|egrep "\bSeconds_Behind_Master\b"|awk '{print $2}')
                    echo $result
            ;;
            *) 
                    echo "Usage:$0(Slave_Running|Seconds_Behind)" 
            ;; 
    esac

## 2. mysql赋权 ##

`grant REPLICATION CLIENT on *.* to zabbix_select@localhost identified by 'zabbix';`

## 3. 查看脚本执行效果 ##

[root@mysql64 shell]# chmod a+x check_mysql_slave.sh 
    [root@mysql64 shell]# sh check_mysql_slave.sh Slave_Running 
    1
    [root@mysql64 shell]# sh check_mysql_slave.sh Slave_Seconds
    0
    [root@mysql64 shell]#

## 4. Zabbix客户端添加自定义key ##

`vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/check_mysql_slave_key`

UserParameter=mysql.slave[*],/usr/local/zabbix/shell/check_mysql_slave.sh $1 $2

## 5. 添加Zabbix监控MySQL主从模板 ##

从Zabbix页面导入模板Template App MySQL Slave.xml，如下链接为模板地址：  
[https://github.com/ygqygq2/zabbix/blob/master/%E6%A8%A1%E6%9D%BF/Template%20App%20MySQL%20Slave.xml][https_github.com_ygqygq2_zabbix_blob_master_E6_A8_A1_E6_9D_BF_Template_20App_20MySQL_20Slave.xml]  
![这里写图片描述][SouthEast]

## 6. 主机链接模板 ##

## 7. 查看结果 ##

在Zabbi Server端查看：

[root@zabbix-server ~]# /usr/local/zabbix/bin/zabbix_get -s mysql-slave-IP -k "mysql.slave[Seconds_Behind]"
    0
    [root@zabbix-server ~]# /usr/local/zabbix/bin/zabbix_get -s mysql-slave-IP -k "mysql.slave[Slave_Running]" 
    1
