现在单位为了省钱，我用了shell脚本，简单的写了一个监控。通过curl一个固定页面的200状态码，如果是200，就说网站是正常的,如果不是200就自动重启网站，然后发邮件到QQ邮箱。自己在上QQ的同时，通过微信也可以收到报警，不但可以收到报警，还可以解决问题。基本上也可以解决web的故障。
#! /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

echo "1657 is reload." >>/home/taoyake/scripts/website-error.`date +%F`.log
