Odoo Run two or more openerp servers simultaneously

How to work on two different versions of openerp simultaneously

When you start openerp server by typing on terminal
./openerp-server
it takes

addons path- bin/addons
database port: 5432
run by default on port : 8069

When you are running single server or single version of openerp ,no special need to specify port . if u want to work with two or more server at same time , then u need to specify different port

./openerp-server –xmlrpc-port=2000 –xmlrpcs-port=2001 –netrpc-port=2002

This command will run your server on 2000 port.
To update any module on this you need to use this command.

./openerp-server -u module -d database –xmlrpc-port=2000 –xmlrpcs-port=2001 –netrpc-port=2002

For first time Start OpenERP server like this:

./openerp-server.py --addons-path=~/home/workspace/stable/addons

The bin/addons will be considered as default addons directory which can be overriden by the~/home/workspace/stable/addons. That is if an addon exists in bin/addons as well as~/home/workspace/stable/addons (custom path) the later one will be given preference over the bin/addons (default path).

Two configuration files are available:

one for the client: ~/.openerprc

one for the server: ~/.openerp_serverrc

“openerprc” file stores default information for client including default addons path.
