zabbix 监控mysql5.6版本 及主从

本文中部分内容是网上摘抄，如版主看到后还望谅解！

一、前期工作

1.导入mysql模板文件到zabbix

百度网盘模板地址：http://pan.baidu.com/s/1o6DkTuE

2.mysql 授权

mysql> grant replication client on *.* to 'zabbix'@'localhost' identified by '密码';

Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

a脚本：（监控mysql 状态脚本）

#more checkmysqlperformance.sh

#!/bin/bash

mysql=$(which mysql)

VAR=$1

# mysql 5.6 use password has waring

# Warning: Using a password on the command line interface can be insecure.

# [ "${var}" = '' ] && echo "" || ${mysql} -u${MYSQL_USER} -p${MYSQL_PASSWORD} -h${MYSQL_HOST} -e 'show status' | grep -v Variable_name | grep "\b${VAR}\b" | awk '{print $2}'

# mysql --defaults-extra-file=./config.cnf -e 'show status'

[ "${VAR}" = '' ] && echo "" || ${mysql} -e 'show status' | grep -v Variable_name | grep "\b${VAR}\b" | awk '{print $2}'

b脚本：（监控mysqlslave 状态）

# more check_mysql_slave.sh

#!/bin/bash

declare -a slave_is

slave_is=($(mysql -e "show slave status\G"|grep -E "Slave_IO_Running|Slave_SQL_Running:"|awk '{print $2}'))

if [ "${slave_is[0]}" = "Yes" -a "${slave_is[1]}" = "Yes" ];then

    echo "OK -slave is running"

    exit 0

else

    echo "Critical -slave is error"

    exit 2

fi

测试结果：

]# sh check_mysql_slave.sh

OK -slave is running

二、.配置zabbix agent 端

1.

# cat /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf

UserParameter=mysql.status[*], /usr/local/bin/checkmysqlperformance.sh $1

UserParameter=mysql.ping, /usr/bin/mysqladmin ping | grep alive | wc -l

UserParameter=mysql.version, mysql -V | cut -f6 -d" " | sed 's/,//'

UserParameter=mysql.slave, /usr/local/bin/check_mysql_slave.sh |grep OK -c

2.重启zabbix_agent

三、zabbix web 端配置监控

1.针对模板中没有配置mysql slave 端items 值进行配置（图中红色部分为服务器ip）



2.配置触发器（图片中红色部分为服务器主机名）



3.停止mysql 和 slave 端进行验证

# stop slave ；
