Cannot change MB_JETTY_PORT Port Number

dturner · April 2, 2020, 5:17pm

I am trying to install Metabase for the first time on a Windows Server 2016 Standard box. I am getting the error below. I tried changing the port number through the PowerShell but that did not work.

Hi @dturner
Could it be something to do with Powershell vs Command Prompt?
Then try this instead:
java -DMB_JETTY_PORT=3100 -jar metabase.jar

dturner · April 2, 2020, 5:54pm

That got me future than I was before but the port still did not change. Thank you so much for your quick response. I will try the command prompt.

endurancezone · February 17, 2022, 3:41pm

Did you get this working? I have tired this command on Windows server but port does not change. I did it with Metabase running. No impact, turned it off ran command still starts on port 3000?

flamber · February 17, 2022, 4:00pm

@endurancezone You're not writing if your are using PowerShell or Command Prompt.
https://www.metabase.com/docs/latest/operations-guide/environment-variables.html
Use the inline way as I described above.

endurancezone · February 17, 2022, 4:16pm

@flamber apologies Command Prompt

endurancezone · February 17, 2022, 4:30pm

@flamber so I have tried the following via CMD and PS

Restart Metabase still on port 3000? Did I miss something or a step?

flamber · February 17, 2022, 4:35pm

@endurancezone Environment variables only persist in the window you are working in. To store them in new windows, then you need to do other things, but that's not specific to Metabase.

Follow what I wrote here: Cannot change MB_JETTY_PORT Port Number

endurancezone · February 17, 2022, 4:42pm

@flamber Thank you that worked! Appreciate the patience and help.

nidhi · June 14, 2022, 9:16am

Hey! I used this on terminal on mac but on opening up localhost 3100, it says this site can't be reached. Can you help?

flamber · June 14, 2022, 9:37am

@nidhi You are running Metabase on another server, not your local computer (aka localhost), so you have to go to the hostname/IP of the other server.

nidhi · June 14, 2022, 10:53am

Thankyou @flamber for the quick response!
Can you please tell me if I can access the GUI of metabase of that server on my localhost ?

flamber · June 14, 2022, 10:57am

@nidhi You'll have to do some SSH tunneling with port forwarding. Search the internet about that, since it has nothing to do with Metabase.
I would recommend that you ask your DevOps team for help on setting up Metabase.

nidhi · June 14, 2022, 11:03am

Thanks @flamber. One last question can we upgrade metabase only using GUI? Becase I wanted to upgrade metabase version which is on that server.

flamber · June 14, 2022, 11:04am

@nidhi No: https://www.metabase.com/docs/latest/operations-guide/upgrading-metabase.html

Thankyou! I saw that link previously but was confused.
