如何在Linux上安装Squid代理服务器软件

1、获取Squid源代码

wget ftp://ftp.cuhk.edu.hk/pub/packages/info-systems/www/squid/squid-3.1.1.tar.gz

2、编译及安装

tar -zxvf squid-3.1.1.tar.gz
cd squid-3.1.1
./configure --prefix=/usr/local/squid --enable-arp-acl --enable-linux-netfilter --enable-pthreads --enable-err-language="Simplify_Chinese" --enable-default-err-language="Simplify_Chinese" --enable-auth="basic" --enable-baisc-auth-helpers="NCSA" --enable-underscore
make
make install

3、编译生成Squid认证程序ncsa_auth

cd helpers/basic_auth/NCSA/
make
cp ncsa_auth /usr/sbin/
cd ../../../

4、使用htpasswd来生成用户名/密码对应的文件

htpasswd -c /usr/local/squid/password hijava 在输入两边密码后,一个hijava用户就生成了。如果以后需要添加用户,把上面的命令去掉-c参数再运行即可。

5、修改Squid配置文件

cd /usr/local/squid/
mv -f etc/squid.conf etc/squid.conf.bak
vi etc/squid.conf 插入如下内容:
acl SSL_ports port 443
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

auth_param basic program /usr/sbin/ncsa_auth /usr/local/squid/password
acl normal proxy_auth REQUIRED
http_access allow normal

# Deny requests to certain unsafe ports
http_access deny !Safe_ports

# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports

# And finally deny all other access to this proxy
http_access deny all

# Squid normally listens to port 3128
http_port 3128

# 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 null /tmp

# Leave coredumps in the first cache dir
coredump_dir /usr/local/squid/var/cache

# 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

6、启动Squid

 ./sbin/squid
