一个网站,使用了cdn,全国各地有几十个节点。需要你写一个shell脚本来监控各个节点是否正常。
假如
- 监控的url为www.yanyi.com/index.php
- 源站ip为88.88.88.88
- 以及各个节点ip列表文件为/tmp/ip.txt
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
| #!/bin/bash url="www.yanyi.com/index.php" s_ip="88.88.88.88" curl -x $s_ip:80 $url > /tmp/source.html 2>/dev/null for ip in `cat /tmp/ip.txt` do curl -x $ip:80 $url 2>/dev/null >/tmp/$ip.html [ -f /tmp/$ip.diff ] && rm -f /tmp/$ip.diff touch /tmp/$ip.diff diff /tmp/source.html /tmp/$ip.html > /tmp/$ip.diff 2>/dev/null n=`wc -l /tmp/$ip.diff|awk '{print $1}'` if [ $n -lt 0 ] then echo "node $ip sth wrong." fi done
