有时光有socks5代理还不行, 有些应用只认http代理,
无奈, socks5 -> http

结合polipo将socks5转换成http代理

sudo apt-get install polipo                                                      
sudo vim /etc/polipo/config 

配置如下:

logSyslog = true                                                                 
logFile = /var/log/polipo/polipo.log                                                 
socksParentProxy = "127.0.0.1:1080"                                              
socksProxyType = socks5                                                          
proxyAddress = "::0"        # both IPv4 and IPv6                                 
# or IPv4 only                                                                   
# # proxyAddress = "0.0.0.0"                                                     
proxyPort = 8123  

启动, 最好不用sudo(基本原则,能不用root权限就不用root权限),

polipo -c /opt/local/etc/polipo/config

使用浏览器可以访问如下页面, 测试polipo是否已启动
http://localhost:8123/
测试是否可用

curl --proxy http://127.0.0.1:8123 https://www.google.com  

其他使用方法

http_proxy=http://localhost:8123 apt-get update                                  
http_proxy=http://localhost:8123 curl www.google.com                             
http_proxy=http://localhost:8123 wget www.google.com                             
git config --global http.proxy 127.0.0.1:8123                                    
git clone https://github.com/xxx/xxx.git                                         
git xxx                                                                          
git xxx                                                                          
git config --global --unset-all http.proxy  

重启

sudo service polipo restart  

帮助

man polipo 

手动编译

编译后在后台启动

$ sudo polipo daemonise=true logFile="/var/log/polipo.log"
