ubuntu18.04-ss-client

一、安装 python-pip

sudo apt install python-pip

二、安装 shadowsocks

sudo pip install shadowsocks

看到 Successfully installed shadowsocks-2.8.2 则代表安装成功

三、配置 shadowsocks

运行：$ sudo gedit /etc/shadowsocks.json

在 shadowsocks.json 文件中写入：

{ 

"server":"代理服务器ip”,

"server_port":代理服务器端口,

"password":"代理服务器访问密码”,  

"local_address":"127.0.0.1”, 

"local_port":1080, 

"timeout":600, 

"method":"aes-256-cfb" // 代理服务器访问数据加密方式，根据自己配置ss 服务端时的配置自行填写

}

四、启动 shadowsocks

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

然后并不是一路顺利，在这里报错了，代码如下

INFO: loading config from ss.json 
2018-10-14 22:47:50 INFO loading libcrypto from libcrypto.so.1.1

func = self._FuncPtr((name_or_ordinal, self)) 
AttributeError: /usr/lib/x86_64-Linux-gnu/libcrypto.so.1.1: undefined symbol: EVP_CIPHER_CTX_cleanup

这个问题是由于在openssl1.1.0版本中，废弃了EVP_CIPHER_CTX_cleanup函数，如官网中所说：

EVP_CIPHER_CTX was made opaque in OpenSSL 1.1.0. As a result, EVP_CIPHER_CTX_reset() appeared and EVP_CIPHER_CTX_cleanup() disappeared. 

EVP_CIPHER_CTX_init() remains as an alias for EVP_CIPHER_CTX_reset().

解决方法：

找到 /usr/local/lib/python2.7/dist-packages/shadowsocks/crypto/openssl.py 文件进行修改，

用vim 或 gedit 命令行都行：

此处以 shadowsocks-2.8.2的版本为例，其他版本自行在文件中搜索

1、将第52行

libcrypto.EVP_CIPHER_CTX_cleanup.argtypes = (c_void_p,)

改为

libcrypto.EVP_CIPHER_CTX_reset.argtypes = (c_void_p,)

2、将第111行

libcrypto.EVP_CIPHER_CTX_cleanup(self._ctx)

改为

libcrypto.EVP_CIPHER_CTX_reset(self._ctx)

修改完之后保存退出即可,然后再次执行：

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

这次应该就能启动成功了！
