三、squid代理服务
1、安装 sudo apt-get install squid
2、配置
a、备份 sudo cp /etc/squid/squid.conf /etc/squid/squid.conf.original
如果不成功,请切换到root用户身份进行,即执行sudo su root
b 、编辑配置文件
#Default:
http_port 3128
#Default:
icp_port 3130
#Recommended minimum configuration:
#acl all src 0.0.0.0/0.0.0.0
acl manager proto cache_object
#acl localhost src 127.0.0.1/255.255.255.255
acl to_localhost dst 127.0.0.0/8
acl SSL_ports port 443 563 # https, snews
acl SSL_ports port 873 # rsync
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 563 # https, snews
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 Safe_ports port 631 # cups
acl Safe_ports port 873 # rsync
acl Safe_ports port 901 # SWAT
acl Safe_ports port 8080 #
acl purge method PURGE
acl CONNECT method CONNECT
#用户分类
acl advance arp 00:15:F2:A8:9F:B1
acl vipuser arp 00:15:F2:A8:9F:B1
acl LanUser src 192.168.1.0/24
acl localhost src 127.0.0.1/32
acl all src 0.0.0.0/0.0.0.0
#行为分类
acl Movies rep_mime_type video/mpeg
acl UPLIMIT req_header Content-Length [5-9][0-9]{5} [0-9]{7,}
acl download urlpath_regex -i \.mp3$ \.avi$ \.rmvb$ \.rm$ \.ra$ \.ram$ \.mpe$ \.smi$ \.torrent$
acl denysite dstdomain .tencent.com
#禁止访问的网站可以列在下面参数的文件内如其中有一行为“.qq.com”就不能访问以qq.com结尾的网站
acl BadSites url_regex "/opt/squid/badsites"
acl worktime time SMTWHFA 7:40-12:00 13:00-21:30
#acl LanUser maxconn 10
#具体规则
http_access allow advance
http_reply_access deny Movies worktime
http_access deny UPLIMIT
http_access deny download worktime
http_access allow vipuser
http_access deny badsites
http_access allow localhost
http_access deny denysite worktime
http_access allow LanUser
http_access deny all
3、初始化,执行squid -z
4、启动 /etc/init.d/squid start
现在可以代理上网了,但是不能透明代理,要想实现透明代理还要做如下设置
a 、修改/etc/squid/squid.conf文件
httpd_accel_host virtual
httpd_accel_port 80
httpd_accel_with_proxy on
b 、iptables实现nat
echo "1" > /proc/sys/net/ipv4/ip_forward #开启ipv4转发功能
iptables -t nat -A POSTROUTING -o ppp0 -s 192.168.1.0/24 -j MASQUERADE
iptables -t nat -A PREROUTING -i eth0 -s 192.168.1.0/24 -p tcp --dport 80 -j REDIRECT --to-ports 3128
这时可以实现透明代理上网了
