1. 安装ss

sudo apt-get update
sudo apt-get install python-pip
sudo pip install shadowsocks

2. 配置json文件

sudo gedit /etc/shadowsocks.json

将下面内容添加到文件中，括号的内容可以删除，注意格式，否则会报错：

{
  "server": "(服务器地址，比如)1.1.1.1",
  "server_port": (服务器端口号，比如)8080,
  "local_port": (本地端口号，比如)1080,
  "password": "(服务器密码，比如)skqhfsaoqou",
  "timeout": (超时时间，比如)300,
  "method": "aes-256-cfb"
}

3. 启动
   本地客户端（作为客户端链接你的服务器）：

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

本地服务器（作为服务器）：

sudo ssserver -c /etc/shadowsocks.json -d start

4. 出错解决办法：
   正常来说，一般会出现下面错误：

Traceback (most recent call last):
  File "/usr/bin/ssserver", line 9, in 
    load_entry_point('shadowsocks==2.8.2', 'console_scripts', 'ssserver')()
  File "/usr/lib/python2.7/site-packages/shadowsocks/server.py", line 34, in main
    config = shell.get_config(False)
  File "/usr/lib/python2.7/site-packages/shadowsocks/shell.py", line 262, in get_config
    check_config(config, is_local)
  File "/usr/lib/python2.7/site-packages/shadowsocks/shell.py", line 124, in check_config

    random_string(self._method_info[1]))
  File "/usr/lib/python2.7/site-packages/shadowsocks/encrypt.py", line 109, in get_cipher
    return m[2](method, key, iv, op)
  File "/usr/lib/python2.7/site-packages/shadowsocks/crypto/openssl.py", line 76, in __init__
    load_openssl()
  File "/usr/lib/python2.7/site-packages/shadowsocks/crypto/openssl.py", line 52, in load_openssl
    libcrypto.EVP_CIPHER_CTX_cleanup.argtypes = (c_void_p,)
  File "/usr/lib64/python2.7/ctypes/__init__.py", line 373, in __getattr__
    func = self.__getitem__(name)
  File "/usr/lib64/python2.7/ctypes/__init__.py", line 378, in __getitem__
    func = self._FuncPtr((name_or_ordinal, self))
AttributeError: /usr/local/ssl/lib/libcrypto.so.1.1: undefined symbol: EVP_CIPHER_CTX_cleanup
shadowsocks start failed

原因是在openssl1.1.0版本中，废弃了EVP_CIPHER_CTX_cleanup函数。参考官网：https://www.openssl.org/docs/man1.1.0/crypto/EVP_EncryptInit.html#HISTORY
解决办法：

1.打开错误提示中的文件：
sudo gedit /usr/lib/python2.7/site-packages/shadowsocks/crypto/openssl.py
2.（全文件共2处）搜索（Ctrl+F）cleanup
找到libcrypto.EVP_CIPHER_CTX_cleanup.argtypes = (c_void_p,)
将其改为libcrypto.EVP_CIPHER_CTX_reset.argtypes = (c_void_p,)
3.再次搜索cleanup，将libcrypto.EVP_CIPHER_CTX_cleanup(self._ctx)
改为libcrypto.EVP_CIPHER_CTX_reset(self._ctx)
4.保存并推出（Ctrl+S）

5. 设置开机启动：

sudo gedit /etc/rc.local

将

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

添加到该文件中

6. 搞定。
