centos7.2 64位安装shadowsocks客户端

$ curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
$ python get-pip.py

$ pip install --upgrade pip
$ pip install shadowsocks

$ vi /etc/shadowsocks.json

{
  "server":"x.x.x.x",             #你的 ss 服务器 ip
  "server_port":8586,                #你的 ss 服务器端口
  "local_address": "127.0.0.1",   #本地ip
  "local_port":1080,              #本地端口
  "password":"cntsp",             #连接 ss 密码
  "timeout":300,                  #等待超时
  "method":"aes-256-cfb",         #加密方式
  "workers": 1                    #工作线程数
}

启动：

sslocal -c /etc/shadowsocks.json -d start 

测试是否连上ss的服务端
运行 curl –socks5 127.0.0.1:1080 http://httpbin.org/ip，如果返回你的 ss 服务器 ip 则测试成功：

{
  "origin": "x.x.x.x"       #你的 ss 服务器 ip
}
