When I started HAProxy under Windows Server, I got the following error - windows

Question

haproxy.exe -f haproxy.cfg -d
When I run HAProxy, I get an error:
'''
Available polling systems :
poll : pref=200, test result OK

Total: 2 (1 usable), will use poll.
Available filters :

[TRACE] trace
Using poll() as the polling mechanism.

In the meantime, no other services are running, and I have the RabbitMQ service open.
My haproxy.cfg file is as follows：

Most of the Internet is due to the version, but I checked the official website, the version is the latest, and I also started the RabbitMQ service, so I don't know where the error is at present

Answer 1

(Address already in use) [0.0.0.0:5672]
it means that the port 5672 (RabbitMQ is already in use. Most likely you have a rabbitmq node running in that machine.
So just change the HA-PROXY port.
