Window 2003 R2下安装squid透明代理

1.下载windows下squid安装包地址：

http://squid.acmeconsulting.it/download/squid-2.7.STABLE8-bin.zip

 

2.将下载的squid安装包解压并放到被安装的windows 2003 R2上c盘，c:\squid

 

3.运行cmd，进入目录c:\squid\etc

a) copy squid.conf.default squid.conf

b) copy mime.conf.default mime.conf

c) copy cachemgr.conf.default cachemgr.conf

d) copy squid_radius_auth.conf.default squid_radius_auth.conf

 

4.修改配置文件squid.conf

 

# Recommended minimum configuration:

acl all src 0.0.0.0/0  #定义所有源网段，默认为所有地址

acl manager proto cache_object

acl localhost src 127.0.0.1/32 #定义环回主机源地址

acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 #定义允许访问的目的网段

 

#acl localhost src 0/0  #针对本机没有必要设置全部网段

 

# Example rule allowing access from your local networks.

# Adapt to list your (internal) IP networks from where browsing

# should be allowed

#定义内部主机源网段分别为10.0.0.0/8、172.16.0.0/12、192.168.0.0/16，  localnet为自定义名称，用于注册那些网段可以上网

acl localnet src 10.0.0.0/8 #RFC1918 possible internal network

acl localnet src 172.16.0.0/12 # RFC1918 possible internal network

acl localnet src 192.168.0.0/16 # RFC1918 possible internal network

 

#此行数用于定义内网ipv6地址段，暂时不用注释即可

#acl localnet src fc00::/7   # RFC 4193 local private network range    

#acl localnet src fe80::/10   # RFC 4291 link-local (directly plugged) machines（本机ipv6地址类似环回）

 

#将端口进行定义，方便以后配置(端口名称可以自定义)

acl SSL_ports port 443 #https

acl Safe_ports port 80 # http

acl Safe_ports port 21 # ftp

acl Safe_ports port 443 # https

acl Safe_ports port 70 # gopher

acl Safe_ports port 210 # wais

acl Safe_ports port 1025-65535 # unregistered ports

acl Safe_ports port 280 # http-mgmt

acl Safe_ports port 488 # gss-http

acl Safe_ports port 591 # filemaker

acl Safe_ports port 777 # multiling http

acl CONNECT method CONNECT

 

forwarded_for transparent

 

# Recommended minimum Access Permission configuration:

# Only allow cachemgr access from localhost

#配置允许或禁止那些源ip或端口访问

http_access allow manager localhost

http_access deny manager

 

# Deny requests to certain unsafe ports

#禁止未定义的端口通信，此处使用的正则表达式，“!”表示取反

http_access deny !Safe_ports

 

# Deny CONNECT to other than secure SSL ports

http_access deny CONNECT !SSL_ports

 

# We strongly recommend the following be uncommented to protect innocent

# web applications running on the proxy server who think the only

# one who can access services on "localhost" is a local user

#http_access deny to_localhost

 

#

# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS

#

 

# Example rule allowing access from your local networks.

# Adapt localnet in the ACL section to list your (internal) IP networks

# from where browsing should be allowed

# 自定义的源ip网段

http_access allow localnet

http_access allow localhost

http_access allow all

 

# And finally deny all other access to this proxy

http_access deny all

 

# Squid normally listens to port 3128

# squid 默认启用3128，此处更改为31288

http_port 31288

 

# We recommend you to use at least the following line.

hierarchy_stoplist cgi-bin ?

 

# Uncomment and adjust the following to add a disk cache directory.

#cache_dir ufs /var/spool/squid 100 16 256

 

# Leave coredumps in the first cache dir

#主要用于备份成的core文件

#注意，在window 2003 R2要创建对应目录，否则会报错

coredump_dir c:/squid/var/squid

 

# Add any of your own refresh_pattern entries above these.

refresh_pattern ^ftp: 1440 20% 10080

refresh_pattern ^gopher: 1440 0% 1440

refresh_pattern -i (/cgi-bin/|\?) 0 0% 0

refresh_pattern . 0 20% 4320

 

#access cache.log 缓存日志的存放位置

#注意，在window2003 R2要创建对应目录，否则会报错

cache_dir ufs c:/squid/var/cache 20480 16 256

cache_log c:/squid/var/cache/cache.log

 

#stroage the path of the pid

#主要用于记录进程的pid，定义的目录一定要正确

pid_filename c:/squid/var/logs/squid.pid

 

#set visible_hostname，注册开启代理的主机名称，注释此选项会warning

visible_hostname iZ25khcmcysZ

 

5.squid命令选项解释

简单介绍一下squid常用选项

C:\squid\sbin>squid.exe -h

Usage: squid [-hirvzCDFIRYX] [-d level] [-s | -l facility] [-f config-file] [-u port] [-k signal] [-n name] [-O command-line]

       -f file   Use given config-file instead of

                 c:/squid/etc/squid.conf #可以自定义配置文件路径

       -i Installs as a Windows Service.

       -k reconfigure|rotate|shutdown|interrupt|kill|debug|check|parse

                 Parse configuration file, then send signal to

                 running copy (except -k parse) and exit.

       -n name   Specify Windows Service name to use for service operations default is: Squid.

       -r        Removes a Windows Service (see -n option).

       -z        Create swap directories

       -X        Force full debugging. #此选项主要用于开启squid服务，并且打印服务启动的过程问题，便于排除错误问题

 

6.常见错误问题追踪

使用squid -X 显示debug信息启动信息

a) 开启主机代理的主机名注册，配置选项visible_hostname iZ25khcmcysZ

 

b) WARNING提示信息，配置选项冗余，如

acl localhost src 0/0 定义本机所有地址，没有必要的

c) ERROR 提示信息，配置选项错误等

pid_filename 定义的路径提示 not found

Cache_log  定义的路径提示 not found

7.在IE浏览器中，修改对应ip和代理端口(此处不做详细介绍)

ok!!!

 

注意：使用squid -X 强制显示debug信息以及进程启动过程中出现哪些失败进程;当启动成功后，会显示进程pid文件。
