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 ${web_url[i]}" [e-mail]
    echo "failed"
  else
    echo "'${web_url[i]}' is ok!"
  fi
}
