Linux使用squid搭建代理服务器

一、安装

Shell ##互联网环境安装 dnf install squid ##查看配置文件 cat /etc/squid/squid.conf ##启动squid默认占用3128端口 sudo systemctl start squid ##设置开机自启动 sudo systemctl enable squid

二、修改配置文件

Shell # # Recommended minimum configuration: # # Example rule allowing access from your local networks. # Adapt to list your (internal) IP networks from where browsing # should be allowed acl localnet src 0.0.0.1-0.255.255.255        # RFC 1122 "this" network (LAN) #acl localnet src 10.0.0.0/8                # RFC 1918 local private network (LAN) #acl localnet src 100.64.0.0/10                # RFC 6598 shared address space (CGN) #acl localnet src 169.254.0.0/16         # RFC 3927 link-local (directly plugged) machines #acl localnet src 172.16.0.0/12                # RFC 1918 local private network (LAN) #acl localnet src 192.168.0.0/16                # RFC 1918 local private network (LAN) acl localnet src fc00::/7               # RFC 4193 local private network range acl localnet src fe80::/10              # RFC 4291 link-local (directly plugged) machiness acl developer src 10.100.9.55/32          # /32仅允许此ip连接 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 # # Recommended minimum Access Permission configuration: # # 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 # Only allow cachemgr access from localhost http_access allow localhost manager http_access deny manager # 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 http_access allow localnet http_access allow localhost http_access allow developer # And finally deny all other access to this proxy http_access deny all # Squid normally listens to port 3128 http_port 3128 # 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 coredump_dir /var/spool/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

二、使用

2.1、Windows使用

Shell #config global proxy ## 代理服务器地址 export proxy="http://ip:3128" #设置http https代理 export http_proxy=$proxy export https_proxy=$proxy #排除内网地址，不通过代理访问 export no_proxy="localhost,127.*,10.*,172.16.*,172.17.*,172.18.*,172.19.*,172.20.*,172.21.*,172.22.*,172.23.*,172.24.*,172.25.*,172.26.*,172.27.*,172.28.*,172.29.*,172.30.*,172.31.*,192.168.*,127.0.0.1"
