rest api server running fail

[wormcc]

Environment

• OS: centos6.5
• Erlang/OTP:
• EMQ: 2.3

Description

the listener for the rest api not running, but when i use the command emqttd_ctl listeners start mqtt:api 8099, it showed Failed to restart mqtt:api listener on 8099, error:not_found , 8099 is the port for the api server in the config file.

How should i start the server? Thx

The mqtt:api port defaults to 8080. You can't start the api port because someone else has already listened on it, right ?

You could change the configuration and restart the emq for now, I'll look at the emqttd_ctl listeners restart problem.

## Default: 0.0.0.0:8080
listener.api.mgmt = 0.0.0.0:8099

I don't know what you want. The listener for rest api would be started after emqttd starting unless the 8080 port has been occupied by other application. If you want to to change the rest api port, change it in etc/emq.conf, then restart emqttd.

If you want to change listen port of rest api when emqttd is running, it is a new feature for us

@terry-xiaoyu I don't think this is bug. It looks like @wormcc 's problem. Maybe he needs a new feature. But I assume that it is not a good idea to change rest api listener's port when emqttd has been started.

@gilbert-wong Thanks for the reply, i have changed the default port 8080 to 8099 in the emq.conf, then i restarted the broker, but the rest api server did not run, and the 8099 port wasn't occupied by other application either.

Execute ./bin/emqttd_ctl listeners and tell me what's printed on terminal

[gilbertwong96]

I don't know what you want exactly, but emqttd_ctl listeners could close listeners by specifying port like this ./bin/emqttd_ctl listeners stop api 8099. You didn't reply in this issue for a long time. So maybe your problem has been solved?
