1、安装shadowsocks
sudo apt-get install python-pip
sudo pip install shadowsocks
2、创建配置文件shadowsocks.json，其中服务器地址、端口号、密码为为购买或免费使用的服务器（比如www.ishadowsocks.org）
{
"server": "xxxx.com",
"server_port": 52239,
"local_address": "127.0.0.1",
"local_port": 1080,
"password": "SOME_PASSWORD",
"timeout": 600,
"method": "aes-256-cfb",
"fast_open": false
}
3、启动shadowsocks
sslocal -c shadowsocks.json
4、安装polipo，进行二次转发（shadowsocks使用socks5协议通信，需搭配浏览器插件使用，若想要在系统全局使用，可使用polipo进行二次转发）
sudo apt-get install polipo
5、编辑配置文件，保存到/etc/polipo/config
# This file only needs to list configuration variables that deviate
# from the default values. See /usr/share/doc/polipo/examples/config.sample
# and "polipo -v" for variables you can tweak and further information.
logSyslog = true
logFile = /var/log/polipo/polipo.log
proxyAddress = "0.0.0.0"
socksParentProxy = "127.0.0.1:1080"
socksProxyType = socks5
chunkHighMark = 50331648
objectHighMark = 16384
serverMaxSlots = 64
serverSlots = 16
serverSlots1 = 32
6、重启polipo服务
sudo service polipo restart
7、设置环境变量（可添加至——/.bashrc文件中使所有shell均可实现全局SOCKS5访问）
export http_proxy="http://127.0.0.1:8123"
export https_proxy="https://127.0.0.1:8123"
8、检测一下是否可以通过socks5协议获取google主页面
curl www.google.com
如果成功则说明可以访问。
