CentOS7利用Mailx发送URL的监控告警邮件

1. 安装mailx

   #安装
   yum install -y mailx
   
   #测试
   echo "received" | mail -s "test mailx" [email protected]

   配置发件信息 /etc/mail.rc

   set from=mailaccess
   set smtp=smtpserver
   set [email protected]
   set smtp-auth-password=******

2. 添加RUL地址文件

   cat urllist
   #aa
   172.16.111.11
   #bb
   172.16.111.12
   #cc
   http://xx.xx.com

3. 监控脚本

   ​ cat monitor.sh

   #!/bin/bash
     #监控xxxx
     while true
     do
         Mail="[email protected]"
         FailCount=0
         Retval=0
         GetUrlStatus() {
                     for ((i=1;i<=3;i++))     
                     do
                             wget -T 3 --tries=1 --spider ${1} >/dev/null 2>&1
                             [ $? -ne 0 ] && let FailCount+=1;    
                     done
                     Date=`date +%F" "%H:%M`
                     if [ $FailCount -gt 1 ];then
                             Retval=1
                             echo "check fail!!!,sendmail....."
                             echo "Date : $Date \n Problem :$urllist服务异常，请尽快处理！" | mailx -v -s "xx监控提醒"  $Mail
   
                     else
                             Retval=0
                             echo "Date : $Date  $urllist is running."
                     fi
                     return $Retval        
          }
          for url in `cat url | sed '/^#/d'`
          do
             GetUrlStatus $urllist
         done
         sleep 60           
     done

4. 启动命令
