如何安装 SQUID 代理服务器

最快的代理服务器运行方法是通过 Docker 运行:

Bash
          docker run --name squid -p 3128:3128 --rm -d \
-e PROXYLOGIN=mylogin \
-e PROXYPASSWORD=mypassword \
anticaptcha/squid
        

如果要设置自己的配置文件,则要设置身份验证方式,然后将其装入 /etc/squid/squid.conf

Bash
          docker run --name squid -p 3128:3128 --rm -d \
-v /path/to/squid.conf:/etc/squid/squid.conf \
anticaptcha/squid
        


另一种方法是通过源建立代理服务器:

Bash
          yum -y install make gcc gcc-c++ libtool wget httpd-tools
wget http://www.squid-cache.org/Versions/v3/3.2/squid-3.2.3.tar.gz
tar -zxf squid-3.2.3.tar.gz
cd squid-3.2.3
./configure
make
make install
        

配置文件示例:

Bash
          #configure the port number
http_port 9191

cache_mem 5 MB
cache_dir ufs /usr/local/squid/var/cache 300 16 256
cache_access_log /usr/local/squid/var/logs/access.log
cache_log /usr/local/squid/var/logs/cache.log
cache_store_log /usr/local/squid/var/logs/store.log
pid_filename /usr/local/squid/var/logs/squid.pid

#squid will run under nobody user

## making it anonymous
forwarded_for transparent
request_header_access Via deny all
request_header_access X-Forwarded-For deny all
request_header_access Cache-Control deny all
        

SQUID 将登录名和密码保存在另一文件中,对于我们来说,该文件是“/usr/local/squid/etc/squid_users”。用“htpasswd”工具管理此文件:

Bash
          htpasswd -c /usr/local/squid/etc/squid_users mylogin
        

完成配置后,要更改 SQUID 目录的权限,并将其作为守护程序运行:

Bash
          chown -R nobody:nobody /usr/local/squid/share /usr/local/squid/var
/usr/local/squid/sbin/squid -z /usr/local/squid/etc/squid.conf
/usr/local/squid/sbin/squid -f /usr/local/squid/etc/squid.conf
        

核实代理服务器是否正在运行并且在接受连接:

Bash
          netstat -lenp|grep squid
