load plugin emq_dashboard wrong about emqx-rel HOT 22 CLOSED

Is there other processes occuping port 18083 ?

from emqx-rel.

emqttd 2.3.11 is running now
Eshell V9.3 (abort with ^G)
([email protected])1> Load emq_mod_presence module successfully.
dashboard:http listen on 0.0.0.0:18083 with 4 acceptors.

emq can start successfully.but when I request 18083,it doesn't work,as the log above presented.

Is there any more logs? The log shows that dashboard's listeners has been started successfully. Run lsof -i:18083 -i:1883 -i:11883 -i:8083 -i:8883 -i:8084 -i:8080 in terminal. The result should be like this:

This is the log screenshot.It seemly shows nothing different.

Of course there is some thing different. What is the process called ibm-mqisdp?

from emqx-rel.

The log shows that the ibm-mqisdp process is listening port 1883,but I don't know why it shows ibm-mqisdp.

@gilbert-wong

from emqx-rel.

So ibm-mqisdp occupy the port 1883 and it triggers abnormal actions of emqttd.

from emqx-rel.

I agree with you.How can I find out the abnormal cause?

Try to kill the process which occupies the port emqttd needs and restart emqttd.

from emqx-rel.

The process PID is 16189.Should i killed it? I have tried restart emqttd many times.But it still doesn't work.

from emqx-rel.

If the process is useless to you, killed it. If it is useful, read the emq documentation and modify the default ports emqttd have to use.

from emqx-rel.

The process is listening port 18083,1883,8080,8083,8084,11883,8883.If I kill it,how does it work? Maybe I get it wrong.Please make it clear, thank you.

Kill all other processes unrelated with emqttd which occupies the port emqttd needs and restart emqttd.

(1) I download the source code from https://github.com/emqtt/emq-relx.git and make.It doesn't work.
(2)If i download the binary code from https://github.com/emqtt/emqttd.git. It work well.
(3)And I remove the plugin emq_dashboard from the deps directory and reload it. It still dosen't work.
(4)Should I remove all the plugins and reload all?Are there some plugins the dashborad rely on?

@gilbert-wong

from emqx-rel.

Sorry, I don't understand what you mean. Why it doesn't work when you make emq-relx ? Did it make failed?

from emqx-rel.

I'm sorry.The source code can make success.What I mean is the dashboard plugin dosen't work.

Which otp version do you use? Which platform do you run emqttd and give me more detailed information. There is no problem when I run emqttd on debian, mac os x , centos, etc.

from emqx-rel.

This is the relx.config file.I add some plugins,these plugins work well.But I don't know if these plugins will influence the dashboard plugin.
@gilbert-wong
This is the centos version.

It is unnecessary to add these plugins. I recommend you to add issue from this template. It makes your issue more clear.

I notice that 3 days ago you said you

remove the plugin emq_dashboard from the deps directory

You thought that emq_dashboard cause the problem so you want to remove this dependency from emq-relx? I do not recommend you to do like this because emq_dashboard is an important component of emqttd.

from emqx-rel.

Sorry,I download emq-relx from https://github.com/emqtt/emq-relx.git,so it is better to add issue here ,I think.Here are three questions:
(1)I remove the emq_dashboard from the deps and reload it from https://github.com/emqtt/emq-dashboard.git.
(2)I just want to know why it doesn't work.If I remove the plugin,will it influence the use of emqttd?
(3)If i reload it from https://github.com/emqtt/emq-dashboard.git,will it work well?

And I will add issue from that template as you say.Thank you very much.
@gilbert-wong

from emqx-rel.

Of course it will influence the use of emqttd ! Why did you need to remove the emq_dashboard from the deps ? The emq-dashboard include erlang code. You need to remake the emq-relx first, then restart emqttd.

from emqx-rel.

Sorry,I don't know erlang very well.I will reload the emq-relx and remake it.Thank you.
