Question

我正在学习Python，我遇到了奇怪的问题。我在我的macOS Sierra本地盒子上运行RabitMQ。从python脚本连接到RabbitMQ服务器总是失败，出现套接字超时错误。同时我可以通过telnet连接。运行Python 2.7和库kombu：

# test.py
from kombu import Connection

connection = Connection('amqp://127.0.0.1')
connection.connect()

结果：

Thunderstorm:test max$ python test.py
Traceback (most recent call last):
  File "test.py", line 6, in <module>
    connection.connect()
  File "/Library/Python/2.7/site-packages/kombu/connection.py", line 261, in connect
    return self.connection
  File "/Library/Python/2.7/site-packages/kombu/connection.py", line 802, in connection
    self._connection = self._establish_connection()
  File "/Library/Python/2.7/site-packages/kombu/connection.py", line 757, in _establish_connection
    conn = self.transport.establish_connection()
  File "/Library/Python/2.7/site-packages/kombu/transport/pyamqp.py", line 130, in establish_connection
    conn.connect()
  File "/Library/Python/2.7/site-packages/amqp/connection.py", line 300, in connect
    self.drain_events(timeout=self.connect_timeout)
  File "/Library/Python/2.7/site-packages/amqp/connection.py", line 464, in drain_events
    return self.blocking_read(timeout)
  File "/Library/Python/2.7/site-packages/amqp/connection.py", line 468, in blocking_read
    frame = self.transport.read_frame()
  File "/Library/Python/2.7/site-packages/amqp/transport.py", line 237, in read_frame
    frame_header = read(7, True)
  File "/Library/Python/2.7/site-packages/amqp/transport.py", line 377, in _read
    s = recv(n - len(rbuf))
socket.timeout: timed out

需要几秒钟并返回超时。在RabbitMq日志的这一刻，我看到了：

=INFO REPORT==== 1-Mar-2017::12:25:00 ===
accepting AMQP connection <0.23773.4> (127.0.0.1:60600 -> 127.0.0.1:5672)

=WARNING REPORT==== 1-Mar-2017::12:25:08 ===
closing AMQP connection <0.23773.4> (127.0.0.1:60600 -> 127.0.0.1:5672):
client unexpectedly closed TCP connection

防火墙已关闭。 Telnet连接成功：

Thunderstorm:test max$ telnet 127.0.0.1 5672
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

如何调试此问题？

Answer 1

通过增加默认连接超时

解决了此问题

Connection('amqp://127.0.0.1/', connect_timeout=15)

无法从Python连接到RabbitMQ
