以Centos 系统为例，确保服务器可以正常连接外网

Centos 6.5 下面默认 安装 postfix

查看

rpm -qa | grep postfix

postfix-2.6.6-2.2.el6_1.x86_64

配置邮件客户端

set [email protected] 

set smtp=smtp.163.com

set [email protected]

set smtp-auth-password=UserPassword

set smtp-auth=login

发送测试邮件  echo "test" | mail -s  "subject"  [email protected]

 

 
登录邮箱查看邮件

应用案列，监控服务器内存每半小时检查一次

监控脚本 + crontab

#!/bin/bash

FreeMem=`free -m |  awk ‘NR==3 {print $NF}‘`

Host="192.168.10.32         localhost32.localdomain"

Infor_mesage="Now $Host  memory is $FreeMem"

if [ $FreeMem -lt 1200  ];then

 echo $Infor_mesage | tee /tmp/message.txt

 /bin/mail -s "`date +%F-%T` $Infor_mesage" [email protected]  < /tmp/message.txt

 else 
 exit 1

 fi

#monitor sys memory
