I'm trying to start an MQTT broker with websocket on my macOS. So I changed just the following two lines on the conf file /usr/local/etc/mosquitto/mosquitto.conf:
listener 9001
protocol websockets
And I try to run it using brew services start mosquitto -d, but it doesn't work. I checked using netstat -nat | grep 9001, but there is no result, and on the logs file /var/log/system.log I can see the following error:
com.apple.xpc.launchd[1] (homebrew.mxcl.mosquitto[46643]): Service exited with abnormal code: 3
If I don't make the changes on the conf file that I said, I can run the broker, but without websocket:
> netstat -nat | grep 1883
tcp6 0 0 ::1.1883 *.* LISTEN
tcp4 0 0 127.0.0.1.1883 *.* LISTEN
How can I solve that?
When I try running without homebrew:
> /usr/local/sbin/mosquitto -c /usr/local/etc/mosquitto/mosquitto.conf
1611655055: mosquitto version 2.0.5 starting
1611655055: Config loaded from /usr/local/etc/mosquitto/mosquitto.conf.
1611655055: Opening websockets listen socket on port 9001.
1611655055: Error: Unable to start any listening sockets, exiting.
