Accessing Remotely to Node-RED server

[Xavi]

Hi, i just installed Node-RED in a VM on Azure.. i started it and it says running on http://127.0.0.1:1880/, and that's localhost.. but if i go to http://myVmIp:1880/ i cant enter into node-red.. maybe it's a really easy question, but how do i do it?

I've not used Azure, so can't give you first-hand advice, but have you set up an endpoint to expose that port?

My teacher has borrowed me the vm so i cant edit any of those settings. is there any other way of accessing the node-red tool ? Am i doing anything wrong? I installed Node-RED in the vm running linux. Then I started it up, and tried to reach it at the VM's IP at the 1880 port.. Is it right?

Hi Xavi

well hopefully he has set up some endpoint port to be open ...

if so then you can edit the Node-RED settings.js file to change the default port to that instead ?

but you have to find that port first.

I asked him to set me an endpoint. He is going to do it tomorrow.. Another question.. I edited the settings.JS file.. Changed the port from 1880 to 1881 (just to try) bit i noticed that, eventi restarting node-red the port is always 1880.. I used VIM on linux console to edit the file andò double-checked if i saved the file.. Any idea why changes on setting.JS doesnt take effect?

In Azure VM's you have to configure the allowed ports. You will need to ask which ports are available. Problem may be that the ports available might already be in use (e.g. 80 and 443 standard web ports).

If that is the case, you will need to be able to configure a proxy. If the VM is already running NGINX web server for example, you can configure it to act as a proxy for NR. You would then access NR using the standard web address but on a folder, e.g. something like myserver.azure.com/proxyred/....

Needless to say, this is tricky to set up. Easier to ask your teacher to open up the NR port instead!

Ok, my teacher opened me the port, now it works flawlessly ;) Thanks for your help.

Now, I have another question. I am trying to edit the settings.js file. I must edit it via command-line, so I'm using VIM. I can edit the file, i save it. But when i restart Node-RED changes do not take effect. Do you know why?

Hi Xavi,

that's odd - I assume you do have write access to save the file correctly (your teacher hasn't blocked that :-) - if you inspect the file afterwards I presume it is still edited...  and you are stopping and restarting the Node-RED process (not just reloading the web page). I have seen some containers revert files when they are restarted (eg Docker etc)  - but VMs are usually OK.

Xavi,

 you can also start Node-RED with the -s option to force it to point to the settings file just to make sure

   node red -s mysettings.js
