如果mysql是源码安装，而且是环境变量的mysql命令，需要将脚本里mysql写成绝对路径

#vim mysql-slave.sh

#!/bin/bash
#监控mysql从状态脚本

commnd() {
    /usr/local/mysql/bin/mysql -uroot -p'123456' -e "show slave status\G;" 2>/dev/null | grep -w $1 | awk -F': ' '{print $2}'
}

if [[ $1 == "Slave_IO_Running" ]];then
    a=`commnd Slave_IO_Running`
#判断是否为Yes，如果是Yes，输出0，否则输出1，触发报警
    [[ "$a" == "Yes" ]] && echo 0 || echo 1
elif [[ $1 == "Slave_SQL_Running" ]];then
    a=`commnd Slave_SQL_Running`
    [[ "$a" == "Yes" ]] && echo 0 || echo 1
elif [[ $1 == "Seconds_Behind_Master" ]];then
    a=`commnd Seconds_Behind_Master`
    b=`cat /tmp/sbm.tmp`
    if [[ $a -ge 600 ]] && [[ $b -ge 600 ]];then
         echo $a
    else
         echo 0
    fi
    echo "$a" > /tmp/sbm.tmp
elif [[ $1 == "Last_Errno" ]];then
    a=`commnd Last_Errno`
    [[ $a -eq 0 ]] && echo 0 || echo 1
elif [[ $1 == "Skip_Counter" ]];then
    a=`commnd Skip_Counter`
    [[ $a -eq 0 ]] && echo 0 || echo 1
else
    echo "Slave_IO_Running | Slave_SQL_Running | Seconds_Behind_Master | Last_Errno | Skip_Counter"
fi

#vim zabbix.agent.conf

UserParameter=slave_status[*],/etc/zabbix/script/mysql-slave.sh $1

验证

# zabbix_get -s 10.0.0.52（监控的主机） -k'slave_status[Slave_IO_Running]'

web界面创建监控项

web界面创建触发值

依次创建监控项跟触发值

键值：

触发器：

图：为0则是正常的，Seconds_Behind_Master是延迟多少秒。超过600也就是10分钟会报警
