“xread block 0 stream mystream $”，但是redis.exceptions.ConnectionError

Question

我想我需要更改默认的redis配置，但我不知道需要更改哪些配置参数。

我没有更改默认的redis配置参数。我想使用xread block 0 streams k $来阻止并等待新消息进入，但它引发异常。

from redis import Redis


db = Redis(host='192.168.1.24', port=32111, db=0)
print(db.keys('*'))
print(db.config_get('*'))
k = db.execute_command('xread block 0 streams k $')

期望是xread block 0 streams k将永久地阻塞，直到接收到新消息。 实际错误消息：

Traceback (most recent call last):
  File "/home/server/.local/lib/python3.5/site-packages/redis/connection.py", line 398, in read_response
    raise socket.error(SERVER_CLOSED_CONNECTION_ERROR)
OSError: Connection closed by server.

During handling of the above exception, another exception occurred:

  File "/home/server/PycharmProjects/test/stream_test.py", line 7, in <module>
    k = db.execute_command('xread block 0 streams k $')
