首先說下在基於linux作業系統的郵件傳送。
簡單的說使用mailx：
yum install mailx -y命令列: mail -s "theme" emailaddress,回車後輸入內容按ctrl+d傳送郵件.
管道符: echo "mail main content" | mail -s "theme" emailaddress
檔案內容作為郵件內容: mail -s "theme" emailaddress < /tmp/t.txt
vim urlwww.zhangruibin.com www.92cnb.com#!/bin/bash
#監控web服務並郵件提醒
while true
domail="[email protected]"
failcount=0
retval=0
geturlstatus() >/dev/null 2>&1
#-t超時時間，--tries嘗試1次，--spider蜘蛛
[ $? -ne 0 ] && let failcount+=1; #訪問超時時，$?不等於0，則failcount加1
done
date=`date +%f" "%h:%m`
if [ $failcount -gt 1 ];then
retval=1
echo "check fail!!!,sendmail....."
## 使用mutt
#echo -e "date : $date\nproblem : $url is not running." | mutt -s "web server monitor" $mail
echo "date : $date \n problem :$url服務掛了" | mailx -v -s "服務監控提醒" $mail
else
retval=0
echo "date : $date $url is running."
fireturn $retval #如果返回值為0，就正常退出迴圈，不為0則繼續迴圈
}for url in `cat url | sed '/^#/d'`
do#geturlstatus $url && echo yes || echo no
geturlstatus $url
done
sleep 600 #死迴圈，設定每600s執行一次
done
nohup sh monitor.sh >>monitor.log &ps -ef|grep monitor
結果：root 454 328 0 03:00 pts/2 00:00:00 grep --color=auto monitor
root 27535 1 0 jun10 ? 00:00:00 sh monitor.sh
