nagios监控mysql主从复制

1 首先开启一个用于进行ab复制监控的sql用户

mysql > grant Replication client on *.* to 'nagios'@'%' identified by 'nagios';

mysql> flush privileges;

2验证的主要命令

mysql -unagios -pnagios -e "show slave status\G"

3编写用于nagios远程监控的脚本

保存在 /usr/local/nagios/libexec/

内容:

#!/bin/sh

declare -a slave_is

slave_is=($(/usr/local/mysql/bin/mysql -unagios -pnagios -e "show slave status\G"|grep 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

给予执行权限chmod +x

chown nagios:nagios

4在nrpe.cfg增加相关命令

command[check_mysql_slave]=/usr/local/nrpe/libexec/chech_mysql_slave

5从nagios服务器上测试

check_nrpe -H 192.168.0.222 -c check_mysql_slave

6nagios severs.cfg 里添加监控服务

主要修改位置

service_description check_mysql_slave

check_command check_nrpe!check_mysql_slave
