mongodb how to change default port

Question

For my project I need to use mongodb on port 80. In fact I can't use the default mongodb port (27017). I must use port 80.

If I edit the config file:

sudo nano /etc/mongodb.conf

and I change the port to 80 then I restart mongodb service, I get this message when I try to connect to mongodb

$ mongo --port 80

MongoDB shell version: 2.4.9
connecting to: 127.0.0.1:80/test
Fri Feb  6 14:16:42.705 Error: couldn't connect to server 127.0.0.1:80 at src/mongo/shell/mongo.js:147
exception: connect failed

If I change the port again to 27017, all work fine.

Can someone help me?

`mongod` is the main database service. `mongo` is just the cli interface. You need to restart `mongod`: http://docs.mongodb.org/manual/tutorial/manage-mongodb-processes — laggingreflex, Feb 06 '15 at 14:39

Check if port is already open by another application or service:

on Windows, open cmd and type: netstat -a

on Linux, type: netstat -lptn

Look for open port 80, like TCP 0.0.0.0:80

If you can't find it, open mongodb.conf and change the net section:

net:
   bindIp: 127.0.0.1
   port: 80

I hope this help you

A port can be used only for one app or service at a same time. I suggest you use another port for mongoDB – MCurbelo Feb 06 '15 at 15:03
