监控网站是否可以正常打开的Shell脚本分享

最近刚好需要测试一下新建站的稳定性,所以写了个SHELL脚本放到本机(最近换了mac本),能够实时查看你需要监控的WEB页面状态,并发送到指定邮箱.

这里赞一下OS X自带有crontab计划任务,可以直接在本机测试脚本啦^_^

# vi check_web_alive.sh

#!/bin/bash

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin

export PATH

# define url

WEB_URL=("http://www.example.com" "http://www1.example.com" "http://www2.example.com")

# check network

NET_ALIVE=$(ping -c 5 8.8.8.8 |grep 'received'|awk 'BEGIN {FS=","} {print $2}'|awk '{print $1}')

if [ $NET_ALIVE == 0 ]; then

    echo "Network is not active,please check your network configuration!"

    exit 0

fi

# check url

for((i=0; i!=${#WEB_URL[@]}; ++i))

{

  ALIVE=$(curl -o /dev/null -s -m 10 -connect-timeout 10 -w %{http_code} ${WEB_URL[i]} |grep"000000")

  if [ "$ALIVE" == "000000" ]; then

    echo "'${WEB_URL[i]}' can not be open,please check!" | mail -s "Website Notification to ${WEB_URL[i]}" yourname@example.com

    echo "failed"

  else

    echo "'${WEB_URL[i]}' is OK!"

  fi

}
