Nagios自定义shell脚本检测MySql的AB复制
1. 建立一个Shell脚本，用于检测MySql的AB复制vim /usr/local/nagios/libexec/check_mysqlab
[*]#!/bin/bash

[*]ipadd=$1
[*]mysql -h $ipadd -u username -ppasswd -e 'stop slave;' &> /dev/null
[*]#mysql -h $ipadd -u username -ppasswd -e 'show slave status \G' &> dev/null
[*]if [ $? -eq 0 ];then
[*] mysql -h $ipadd -u username -ppasswd -e 'start slave;' &> /dev/null
[*] num=`mysql -h $ipadd -u amoebauser -pabc -e 'show slave status \G' | grep -c Yes`
[*] if [ $num -eq 2 ];then
[*] echo "OK";
[*] exit 0;
[*] else
[*] echo "Error";
[*] exit 2;
[*] fi
[*]else
[*] echo "Error";
[*] exit 2;
[*]fi
chown nagios.nagios /usr/local/nagios/libexec/check_mysqlab
chmod a+x /usr/local/nagios/libexec/check_mysqlab
2.配置Nagios,在Nagios中加入新命令调用该脚本
vim /usr/local/nagios/etc/objects/commands.cfg
[*]define command{
[*] command_name check_mysql_ab
[*] command_line $USER1$/check_mysqlab $HOSTADDRESS$
[*] }
3.配置Nagios，建立新的被监控对象和被监控服务
vim /usr/local/nagios/etc/objects/localhost.cfg
[*]define host {
[*] host_name 192.168.50.62
[*] alias 50.62
[*] address 192.168.50.62
[*] check_command check-host-alive
[*] notification_options d,u,r
[*] check_interval1
[*] max_check_attempts 2
[*] contact_groupsadmins
[*] notification_interval 10
[*] notification_period 24x7
[*]}
[*]define service{
[*] host_name 192.168.50.62
[*] service_description mysqlab
[*] check_period 24x7
[*] normal_check_interval 2
[*] retry_check_interval 1
[*] max_check_attempts 3
[*] notification_period 24x7
[*] notification_options w,u,c,r
[*] check_command check_mysql_ab
[*]}
