GFW BLOG（功夫网与翻墙）: squid 单网卡架设n个代理服务器方法

由于新公司需要抓取数据，经常被封掉，而在外面买地代理却不稳定，于是俺就提出了自建代理，没想到北京8M的光纤竟然给了十来个公网ip，于是俺就在一张网卡上配置了十来个公网ip地址，然后安装squid，结果squid设定监听不同地公网ip，然而出去地ip却一直是eth0地，而不是eth0:1地ip地址，于是就按照网上说地添加了：

acl ip1 myip 114.113.221.50

tcp_outgoing_address 114.113.221.50 ip1

这样eth0:1 出去地ip也就是eth0:1地ip地址了

下面为了在一台机器上面启动多个squid于是就制作了多个配置文件，但是一定要把每个配置文件地pid，log，cache等指定到不同地位置，不然会出错地：

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

pid_filename /usr/local/squid/var/logs/squid50.pid

cache_log /usr/local/squid/var/logs/cache50.log

access_log /usr/local/squid/var/logs/access50.log

接下来就是要设定匿名代理不然还是会被封掉：

request_header_access Allow allow all

request_header_access Authorization allow all

request_header_access WWW-Authenticate allow all

request_header_access Proxy-Authorization allow all

request_header_access Proxy-Authenticate allow all

request_header_access Cache-Control allow all

request_header_access Content-Encoding allow all

request_header_access Content-Length allow all

request_header_access Content-Type allow all

request_header_access Date allow all

request_header_access Expires allow all

request_header_access Host allow all

request_header_access If-Modified-Since allow all

request_header_access Last-Modified allow all

request_header_access Location allow all

request_header_access Pragma allow all

request_header_access Accept allow all

request_header_access Accept-Charset allow all

request_header_access Accept-Encoding allow all

request_header_access Accept-Language allow all

request_header_access Content-Language allow all

request_header_access Mime-Version allow all

request_header_access Retry-After allow all

request_header_access Title allow all

request_header_access Connection allow all

request_header_access Proxy-Connection allow all

request_header_access User-Agent allow all

request_header_access Cookie allow all

request_header_access All deny all

下面贴上整个squid地配置文件:

# Recommended minimum configuration:

# 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

http_access allow all
