无法让twemproxy使用Python redis

Question

我安装了nutcracker 0.4.0，并在配置中包含以下内容：

redis:
    listen: 127.0.0.1:22121
    hash: fnv1a_64
    distribution: ketama
    auto_eject_hosts: true
    redis: true
    server_retry_timeout: 2000
    server_failure_limit: 10
    servers:
    - 127.0.0.1:6379:1

代码：

 >>> client = redis.StrictRedis(host='127.0.0.1', port=22121, db=1)
 >>> client.set('a', 'b')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/sudheer/workspace/pvenvs/p2s/lib/python2.7/site-packages/redis/connection.py", line 137, in _read_from_socket
    (e.args,))
redis.exceptions.ConnectionError: Error while reading from socket: ('Connection closed by server.',)

如何让Twemproxy与redis-py一起工作？

我找到了我的问题的解决方案。Python redis客户端发送SELECT命令时，配置的URL类似: 127.0.0.1:6379?db=1。db=1触发SELECT命令，这是胡桃夹子不支持的。我把它改成了db=0，现在一切正常。
