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.

related question: Is it possible to run same app(two instances) in different ports? I tried to run same app in 3000 and 5000 ports and second one is showing errors related to mongodb – Quadrivalent

It's definitely possible; I have several apps that run on my website. Your app instances probably conflict while use the same database though - hence the Mongo errors. – Hove

getting this error "Exception in callback of async function: Error: connection closed" @Dan Dascalescu – Almanza

How can we run the several apps on the same server please give me example.we are running single app at time.please help me @dan-dascalescu – Almanza

That is a different question; see this and this. – Hove

Is there a way to do this with the settings.json file? – Subito

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.

This doesn't answer the question, it's more appropriate as a few comments. – Rhetor

Answer 3

No, it is mainly used the default port of 3000 or any state at the start, and the following (+1) to Mongo.
That is, the following application can be run through a 2-port, already in 3002, hence the previous 2-port as before - it is 2998.

Check can be very simple (Mac, Linux):

ps|grep meteor

Just use different db instance (set METEOR_LOCAL_DIR)

 "devOne": "export METEOR_LOCAL_DIR=.meteor/local/db2 && meteor --settings settings1.json --port 3000",
 "devTwo": "meteor --settings settings2.json --port 4000"
