我正在学习 Python,但遇到了奇怪的问题。我在我的 macOS Sierra 本地机器上运行 RabitMQ。从 python 脚本连接到 RabbitMQ 服务器总是失败并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
它需要几秒钟并返回超时。此时在 RabbitMq 日志中,我看到:
=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 ===

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 '^]'.
我该如何调试这个问题?
