精准清除Squid缓存的shell脚本
发布时间：2014-11-20 编辑：jiaochengji.com
本文介绍下，可以精准清除squid缓存的一个shell脚本，有需要的朋友参考。
此脚本在之前的基础上有修改，增加了if选项，并根据$1参数类型来选择性的列出缓存文件所在地址（因为$1并不固定，有时是特定的jpg类型，有时是域名）。
在Squid缓存服务器上应用的很好，特些分享给大家。
脚本内容：
复制代码 代码示例:
#!/bin/sh
squidcache_path="/usr/local/squid/var/cache"
squidclient_path="/usr/local/squid/bin/squidclient"
#grep -a -r $1 $squidcache_path/* | strings | grep "http:" | awk -F 'http:' '{print "http:"$2;}' | awk -F\' '{print $1}' > cache.txt
if [[ "$1" == "swf" || "$1" == "png" || "$1" == "jpg" || "$1" == "ico" || "$1" == "gif" || "$1" == "css" || "$1" == "js" || "$1" == "html" || "$1" == "shtml" || "$1" == "htm" ]]; then
grep -a -r .$1 $squidcache_path/* | strings | grep "http:" | awk -F 'http:' '{print "http:"$2;}' | awk -F\' '{print $1}' | grep "$1$" | uniq > cache.txt
else
grep -a -r $1 $squidcache_path/* | strings | grep "http:" | awk -F 'http:' '{print "http:"$2;}' | awk -F\' '{print $1}' | uniq > cache.txt
fi
cat cache.txt | while read LINE
do
$squidclient_path -p 80 -m PURGE $LINE
done
squidcache_path="/usr/local/squid/var/cache"
squidclient_path="/usr/local/squid/bin/squidclient"
#grep -a -r $1 $squidcache_path/* | strings | grep "http:" | awk -F 'http:' '{print "http:"$2;}' | awk -F\' '{print $1}' > cache.txt
if [[ "$1" == "swf" || "$1" == "png" || "$1" == "jpg" || "$1" == "ico" || "$1" == "gif" || "$1" == "css" || "$1" == "js" || "$1" == "html" || "$1" == "shtml" || "$1" == "htm" ]]; then
grep -a -r .$1 $squidcache_path/* | strings | grep "http:" | awk -F 'http:' '{print "http:"$2;}' | awk -F\' '{print $1}' | grep "$1$" | uniq > cache.txt
else
grep -a -r $1 $squidcache_path/* | strings | grep "http:" | awk -F 'http:' '{print "http:"$2;}' | awk -F\' '{print $1}' | uniq > cache.txt
fi
cat cache.txt | while read LINE
do
$squidclient_path -p 80 -m PURGE $LINE
done
