安裝S_S相關報錯的troubleshooting

衡子發表於2018-09-07

在安裝S_S server時，在Debian上會出現類似如下的報錯：

File "/usr/local/bin/ssserver", line 11, in <module>
    sys.exit(main())
  File "/usr/local/lib/python2.7/dist-packages/shadowsocks/server.py", line 34, in main
    config = shell.get_config(False)
  File "/usr/local/lib/python2.7/dist-packages/shadowsocks/shell.py", line 262, in get_config
    check_config(config, is_local)
  File "/usr/local/lib/python2.7/dist-packages/shadowsocks/shell.py", line 124, in check_config
    encrypt.try_cipher(config['password'], config['method'])
  File "/usr/local/lib/python2.7/dist-packages/shadowsocks/encrypt.py", line 44, in try_cipher
    Encryptor(key, method)
  File "/usr/local/lib/python2.7/dist-packages/shadowsocks/encrypt.py", line 83, in __init__
    random_string(self._method_info[1]))
  File "/usr/local/lib/python2.7/dist-packages/shadowsocks/encrypt.py", line 109, in get_cipher
    return m[2](method, key, iv, op)
  File "/usr/local/lib/python2.7/dist-packages/shadowsocks/crypto/rc4_md5.py", line 33, in create_cipher
    return openssl.OpenSSLCrypto(b'rc4', rc4_key, b'', op)
  File "/usr/local/lib/python2.7/dist-packages/shadowsocks/crypto/openssl.py", line 76, in __init__
    load_openssl()
  File "/usr/local/lib/python2.7/dist-packages/shadowsocks/crypto/openssl.py", line 52, in load_openssl
    libcrypto.EVP_CIPHER_CTX_cleanup.argtypes = (c_void_p,)
  File "/usr/lib/python2.7/ctypes/__init__.py", line 375, in __getattr__
    func = self.__getitem__(name)
  File "/usr/lib/python2.7/ctypes/__init__.py", line 380, in __getitem__
    func = self._FuncPtr((name_or_ordinal, self))
AttributeError: /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1: undefined symbol: EVP_CIPHER_CTX_cleanup

看報錯應該是/usr/local/lib/python2.7/dist-packages/shadowsocks/crypto/openssl.py檔案中的EVP_CIPHER_CTX_cleanup沒有定義。

根據網上的攻略，可以這樣修改：

sed -i "s/libcrypto.EVP_CIPHER_CTX_cleanup/libcrypto.EVP_CIPHER_CTX_reset/g" /usr/local/lib/python2.7/dist-packages/shadowsocks/crypto/openssl.py

把檔案中的EVP_CIPHER_CTX_cleanup都改成EVP_CIPHER_CTX_reset.

再啟動服務，可以正常執行了。
