How run multiple meteor servers on different ports

Question

How can meteor run on multiple ports.For example if the meteor run on 3000 i need another meteor app run on the same terminal.Please help me.

Answer 1

You can use the --port parameter:

`meteor run --port 3030`

To learn more about command line parameters, run meteor help <command>, e.g. meteor help run.

I see you've tagged your question meteor-up. If you're actually using mup, check out the env parameter in the config file.

Answer 2

I think the OP was referring to the exceptions caused because of locks on the mongo db. I am only on this platform for last week - and am learning as quick as I can. But when I tried running my application from the same project directory as two different users on two different ports - I got an exception about MongoDB :

Error: EBUSY, unlink 'D:\test\.meteor\local\db\mongod.lock'

The root of the issue isn't running on different ports - it is the shared files between the two instances - Specifically the database.

I don't think any of your answers actually helped him out. And .. neither can I yet.

I see two options -

First -

I am going to experiment with links to see if I can get the two users to use a different folder for the .meteor\local tree ... so both of us can work on the same code at the same time - but not impact each other when testing.

But I doubt if that is what the OP was referring to either (different users same app)...

Second - is trying to identify if I can inject into the run-mongo.js some concept of the URL / port number I am running on, so the mongodb.lock (and db of course) ... are named something like mongodb.lock-3000

I don't like the 2nd option because then I am on my own version of standard scripts.
