Install shadowsocks:

$ sudo apt-get update
$ sudo apt-get install shadowsocks

Configuration

Edit shadowsocks config file /etc/shadowsocks/config.json:

$ sudo vi /etc/shadowsocks/config.json

Here is my config file

   "server":"0.0.0.0",
   "server_port":8388,
   "local_port":0,
   "password":"demo",
   "timeout":600,
   "method":"aes-256-cfb"
}

Explanation of the fields:
