How to start Dashboar - Githubissues

UlissesZorzan commented 3 years ago

I'm starting with EMQ and I've read the documentation a lot, but I'm not able to use the dashboard.

I installed version 4.2.1 for Centos 7.

The Broker works normally, I just can't use the Dashboard on port 18083 as described in the documentation

I checked if there was any process on that door and found nothing.

If anyone can help me I will be grateful!

It is possible that the port 18083 on your host is already occupied by another program, causing the emqx_dashboard plugin to fail to start.

Apparently there is no process running on port 18083 Would I have any way to check the application log or try to start the Dashboard plugin manually

[greenwave-xx@##]$ sudo lsof -w -n -i tcp:1883 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME node 3056 root 24u IPv4 188996 0t0 TCP 127.0.0.1:34826->127.0.0.1:ibm-mqisdp (ESTABLISHED) beam.smp 32159 emqx 36u IPv4 176264 0t0 TCP *:ibm-mqisdp (LISTEN) beam.smp 32159 emqx 40u IPv4 190208 0t0 TCP 127.0.0.1:ibm-mqisdp->127.0.0.1:34826 (ESTABLISHED) [greenwave-xx@##]$ sudo lsof -w -n -i tcp:18083 [greenwave-xx@##$ sudo lsof -w -n -i udp:18083 [greenwave--xx@##]$

É possível que a porta 18083 em seu host já esteja ocupada por outro programa, fazendo com que o plugin emqx_dashboard falhe ao iniciar.
