1. 安装squid2.7版本，一定要2.7版本，新版本不支持

$ ./configure --prefix=/usr/local/squid --sysconfdir=/usr/local/squid/etc --bindir=/usr/local/squid/bin --sbindir=/usr/local/squid/sbin --mandir=/usr/local/squid/share/man --enable-gnuregex --enable-carp --enable-async-io=80 --enable-removal-policies=heap,lru --enable-icmp --enable-delay-pools --enable-useragent-log --enable-referer-log --enable-kill-parent-hack --enable-snmp --enable-arp-acl --enable-htcp --enable-cache-digests --enable-default-err-language=Simplify_Chinese --enable-err-languages="Simplify_Chinese" --enable-poll --enable-linux-netfilter --disable-ident-lookups --enable-underscores --enable-auth="basic" --enable-basic-auth-helpers="NCSA" --enable-external-acl-helpers="ip_user" --enable-x-accelerator-vary

$ make

$ make install

2. 修改配置文件

$ cd /usr/local/squid/

在alc部分添加下面代码

#rewrite store url youku tudou souhu iqiyi
acl store_url url_regex -i ^http:\/\/[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\/.*(\.flv|\.m4v\?|\.f4v\?|\.mp4\?|\.ts\?|\.letv\?)
acl store_url_no_domain urlpath_regex -i ^\/(.*\/.*\.flv$)

storeurl_access allow store_url
storeurl_access allow store_url_no_domain
storeurl_access deny all

storeurl_rewrite_program /usr/local/squirm/bin/squirm
storeurl_rewrite_children 5

3. 运行squid

第一次运行时，先运行squid -z创建缓存文件夹。缓存文件夹在/usr/local/squid/var下创建，因此创建缓存前还需运行chmod 777 /usr/local/squid/var给该文件夹权限。

再运行squid -d 1开启squid即可。

如果要关闭squid，运行squid -k shutdown则是安全关闭。

$ /usr/local/squid/sbin/squid

启动时报错了，如下

FATAL: Cannot open '/usr/local/squid/var/logs/access.log' for writing.

The parent directory must be writeable by the

user 'nobody', which is the cache_effective_user

set in squid.conf.

Squid Cache (Version 2.7.STABLE9): Terminated abnormally.

CPU Usage: 0.005 seconds = 0.001 user + 0.004 sys

Maximum Resident Size: 15008 KB

Page faults with physical i/o: 0

修改权限解决：

$ chown -R nobody /usr/local/squid/var/logs/access.log

$ echo>var/logs/store.log

$ chown -R nobody /usr/local/squid/var/logs/store.log

$ ./sbin/squid -z

$ ./sbin/squid -d 1

4. 修改/etc/resolve.conf添加DNS

# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

nameserver 192.168.237.2

nameserver 192.168.199.1

nameserver 114.114.114.114

nameserver 8.8.8.8

search localdomain

5. 安装squirm

wget http://squirm.foote.com.au/squirm-1.0betaB.tar.gzmv squirm-1.0betaB.tar.gz /usr/local/srccd /usr/local/src/tar xvf squirm-1.0betaB.tar.gzcd squirm-1.0betaBcd regex./configuremake cleanmakecp -p regex.o regex.h ../cd ../makemake install

6. 配置squirm

$ cd /usr/loca/squirm/etc/

$ cp squirm.local.dist squirm.local

$ squirm.patterns.dist squirm.patterns

修改squirm.local文件，将客户端所在的IP地址段，以标准C类IP地址段为单位，以192.168.1的形式，每行一个记录，写入到该文件中。这些地址，不是squid进程所在的主机IP，而是使用squid的客户端的IP地址，即用户IP。

[root@webcache ~]# more /usr/local/squirm/etc/squirm.local127.0.010.1.510.1.6

编辑squirm.patterns文件，重写来自优酷以及其他在线视频网站的“媒体文件URL”。

通过squidclient -h 127.0.0.1 mgr:store_rewriter命令查询squirm的运行状态。如下所示，
