Hi all,

I am needing to change the port number of the node-red dash it does not matter if it effects both the flow editor and the dash.

does anyone have any experience with this? I am struggling to find any information, any hints are much appreciated.

Thanks

Have a look at your **settings.js** file in the node-red installation dir.

Hi thank you for your response. I have found 6 files in different locations all named settings.js, please could you be more specific about which one I am to look at making alterations too?

please see screen shot, your input is much appreciated thank you.

It's neither.

The one Node-RED uses is printed at startup and will usually be in your home directory in `~/.node-red/settings.js` if you didn't change anything.

You can also pass the port with the `-p` parameter, depending on how you start Node-RED.

Here's more info about that from the documentation:

Hi Kuema, thank you for your input. is this true even if node-red is installed as a snap on ubuntu server?

I used the locate command which normally finds every instance of a file name in every location on the machine, I double checked in the home directory and cannot find a any settings.js file in that location.

I have taken a look at the document you have linked me and attempted to start node-red using the following

sudo snap enable node-red -p 1980

unfortunately node-red does not understand the flag i am sending it, I am wondering if this information still applies when installed as a snap.

many thanks.

That won't work that way.

I don't use snap myself, so I can't tell _where_ it stores the user data.

Is there a way to view the logs of snap apps? That would give a clue where to search for the workspace directory.

Any snap experts here? 😅

It appears that the name snap is appropriate snaps seem to be the cause of all my issues lately making me ready to snap my keyboard 😄

thank you for the help Kuema I will keep trying am sure I will figure it out eventually.

Yep, I dislike the fact that Canonical had to introduce yet another package management system. They even migrated Chromium to snap which caused me some trouble. But that's another topic. 🙈

You could try something like `snap logs node-red` to view the logs. 🤔

Hi dceejay thank you for your help. I have taken a look at the link you have sent me.

I found the settings.js file at the location shown in the ReadMe.

`/root/snap/node-red/current/`

I than change the port number the server is to listen too.

![nodered port](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/4/9/495bc7006675d40c7841cbc4bf46adbaf37d5001.png)

I then restarted node-red snap restart node-red

unfortunately node-red is still listening to port 1880 😕

You need to stop and restart it... you can use the journalctl command mentioned to see the log and see what port it starts up on.

</div>

thank you for your reply dceejay, I have confined that the settings.js file has been altered and saved with the new port number, I have defiantly stopped, started, and restarted node-red.

and I can confirm by using the journalctl that the server is still listening to the default port, from the documentation you kindly provided I cannot find any reason why the changes are not taken effect?

thank you for your support it is much appreciated.

How have you changed that line ? - removed the process.env.PORT part and just left the number hopefully. I have just checked mine here and doing a `sudo snap stop node-red` and `sudo snap start node-red` def picks it up. (as long as you are fixing the correct file.

dceejay, please see image to see how I have changed the line.

![port mod](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/7/2/729eeb9918af4d1cbfd6117e6ff6b942661daf09.png)

I will remove to process.env.PORT and leave the number as you have instructed and get back to you.

thank you

changing the uiport line to this, seems to stop node-red listening all together.

Remove the `||` as well - otherwise it isn't a valid javascript statement.
