Changing the listening port

The --http-port=<port> command option (or just -p <port>) allows us to change the listening port of a server instance from the default 8069. This can be used to run more than one instance at the same time, on the same machine.

Let's try this out. Open two terminal windows. On the first, run this:

$ ~/odoo-dev/odoo/odoo-bin --http-port=8070

Run the following command on the second terminal:

$ ~/odoo-dev/odoo/odoo-bin --http-port=8071

There you go, two Odoo instances on the same server listening on different ports! The two instances can use the same or different databases, depending on the configuration parameters used. And the two could be running the same or different versions of Odoo.
