套接字错误：Errno 111 连接被拒绝
[英]Socket Error: Errno 111 Connection Refused
问题描述
im trying to connect to a locally hosted HiveMQ broker using a RaspberryPi Virtual Machine (Using Oracle VM VirtualBox).
我正在尝试使用 RaspberryPi 虚拟机（使用 Oracle VM VirtualBox）连接到本地托管的 HiveMQ 代理。 im using Mqtt.fx aswell as a second client to look at if the published messages are being recieved.我使用 Mqtt.fx 以及第二个客户端来查看是否收到了发布的消息。
i was using "iot.eclipse.org" before i tried using the local hivemq broker and it worked fine.在尝试使用本地 hivemq 代理之前，我使用的是“iot.eclipse.org”，它运行良好。 so im not too sure what the problem is.所以我不太确定问题是什么。 maybe im just forgetting something.也许我只是忘记了一些东西。
im using the paho mqtt module.我正在使用 paho mqtt 模块。 and my library code is heavily ripped from here: https://pypi.python.org/pypi/paho-mqtt我的库代码从这里被大量撕掉： https : //pypi.python.org/pypi/paho-mqtt
im using a library/module and then referencing that in another .py file.我使用一个库/模块，然后在另一个 .py 文件中引用它。 This is the code from the library/module:这是库/模块中的代码：
import paho.mqtt.client as mqtt
client = mqtt.Client()
#Called on connection to server/broker
def on_connect(client, userdata, rc):
print("connected with result code"+str(rc))
#Called when new message published to subscribed topic
def on_message(client, userdata, msg):
print("NEW PUBLISH: "+msg.topic+" "+str(msg.payload))
#configure connection to the broker
def setup():
client.on_connect = on_connect
client.on_message = on_message
#Subscribe
def subscribe(topic):
print("subscribing to topic: " +topic)
client.subscribe(topic)
#Connect to broker
def connect():
client.connect("127.0.0.1", 1883, 60)
def publish(topic, msg):
client.publish(topic, msg)
and this is the code im actually running.这是我实际运行的代码。 Just 2 simple publishes:只需 2 个简单的发布：
import mqttLib as owly
owly.setup()
owly.connect()
owly.publish("test/library", "test okay :)")
num1 = input("1st number: ")
num2 = input("2nd number: ")
mult = num1 * num2
owly.publish("test/mult", mult)
This is the message i get after running it:这是我运行后得到的消息：
Traceback (most recent call last):
File "mqttTest.py", line 6, in <module>
owly.connect()
File "/home/rpi/python/MQTT/mqttLib.py", line 27, in connect
client.connect("127.0.0.1", 1883, 60)
File "/usr/local/lib/python2.6/dist-packages/paho/mqtt/client.py", line 612, In connect
return self.reconnect()
File "/usr/local/lib/python2.6/dist-packages/paho/mqtt/client.py", line 732, in reconnect
sock = socket.create_connection((self._host, self._port))
File "/usr/lib/python2.6/socket.py", line 514, in create_connection
raise error, msg
socket.error: [Errno 111] Connection refused
The fact it works on a remotely hosted broker.它适用于远程托管代理的事实。 and not locally confuses me.而不是本地让我感到困惑。
i have stripped off most of the plugins on HiveMQ and left the message log plugin on HiveMQ aswell so i dont think its anything to do with authentication.我已经去掉了 HiveMQ 上的大部分插件，并在 HiveMQ 上留下了消息日志插件，所以我认为它与身份验证无关。
i think the virtual machine im using is ubuntu if that helps!如果有帮助，我认为我使用的虚拟机是 ubuntu！
Thank you for your time in advance!提前感谢您的时间！

As mentioned in the comments, 127.0.0.1 is the local address of the VM, what you need to use is the IP address of the host where the broker is running.正如评论中提到的，127.0.0.1是VM的本地地址，您需要使用的是运行代理的主机的IP地址。
In this case the broker host is on the VM host, you can get address of the VM host using the ip route command on the VM, it's output it will look something like this:在这种情况下，代理主机在 VM 主机上，您可以在 VM 上使用ip route命令获取 VM 主机的ip route ，它的输出将如下所示：
default via 192.168.56.100 dev eth0
192.168.56.0/24 dev eth0 proto kernel scope link src 192.168.56.100
The IP address you want to use for your broker should be the one in the line that starts with default, in the example case 192.168.56.100您要用于代理的 IP 地址应该是以 default 开头的行中的 IP 地址，在示例中为192.168.56.100
