現在單位為了省錢，我用了shell腳本，簡單的寫了一個監控。通過curl一個固定頁面的200狀態碼，如果是200，就說網站是正常的,如果不是200就自動重啟網站，然后發郵件到QQ郵箱。自己在上QQ的同時，通過微信也可以收到報警，不但可以收到報警，還可以解決問題。基本上也可以解決web的故障。

代碼如下:  
#! /bin/bash
source /etc/profile
A="web is Good !"
ip=`ifconfig eth0 | grep "inet addr" | awk -F "[: ]+" '{print $4}'`
tt1=`curl -I -s http://xx.8x.18x.xx:1657/product/pro_detail_-rg000785.shtml | head -1 | cut -d " " -f2`
Process=`ps -ef | grep java | egrep  "tomcat1" | awk -F " " '{print $2}'`
if [ $tt1 = "200" ]
  then
  echo "$A" >>/home/taoyake/scripts/website-error.`date +%F`.log
else
  /opt/tomcat1/bin/shutdown.sh
  cd /opt/tomcat1/work/Catalina/
  rm -rf localhost
  kill -9 $Process
  /opt/tomcat1/bin/startup.sh
  echo "1657 is reload." >>/home/taoyake/scripts/website-error.`date +%F`.log
  echo "1657 is reload." | mail -s "website-1657" "505065674@qq.com"
fi

代碼如下:
 more /home/taoyake/scripts/reload_website-1658.sh
#! /bin/bash
source /etc/profile
B="1658 is Good !"
ip=`ifconfig eth0 | grep "inet addr" | awk -F "[: ]+" '{print $4}'`
tt1=`curl -I -s http://xx.xx.183.xx:1658/product/pro_detail_-rg000785.shtml | head -1 | cut -d " " -f2`
Process=`ps -ef | grep java | egrep  "tomcat2" | awk -F " " '{print $2}'`
if [ $tt1 = "200" ]
  then
  echo "$B" >>/home/taoyake/scripts/website-1658-access.`date +%F`.log
else
  /opt/tomcat2/bin/shutdown.sh
  cd /opt/tomcat2/work/Catalina/
  rm -rf localhost
  kill -9 $Process
  /opt/tomcat2/bin/startup.sh
  echo "1658 is reload." >>/home/taoyake/scripts/website-1658-error.`date +%F`.log
  echo "1658 is reload." | mail -s "website-1658" "505065674@qq.com"
