Thanks for your reply. Using sudo /etc/init.d/openerp-server start is fine, but it seems nothing happen after run this command. What is the different between with these two command? /etc/init/openerp-server start and openerp-server start

The main difference is that openerp-server is the main executable of the server, but /etc/init/openerp-server is a init script that surely calls openerp-server executable but before prepare the environment (load path of modules, etc...). Anyway, once the server is running you must go to firefox (or similar) and load localhost:8069

Thanks. Do you mean /etc/init/openerp-server calls some preparation work while openerp-server does not? I use '/etc/init/openerp-server' but cannot load the service from browser. I checked process list of Ubuntu and did not find openerp service running.

I really using it in a debian server, but Ubuntu maybe similar. After sudo /etc/init.d/openerp-server start nothing happens? In my system I got an "Starting openerp-server: openerp-server." Try looking in /var/log/openerp/openerp-server.log for any error. You have Postgresql installed?
