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 statusG"|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 ；

验证图片（图中标红的部分是主机和个人邮箱）
