OpenERP install and config

For a very long time I have been wanting to test OpenERP for basic invoicing and inventory management for a small business.

OpenERP installation on Ubuntu Linux
Gave me the basic instruction to:

• Configure postgreeSQL (in the file
  

  /etc/postgresql/8.4/main/pg_hba.conf) 

•  Create a database user called "openerp"
•  Configure OpenERP server (in the file
  

  /etc/openerp-server.conf )

I now started the OpenERP client and can see  "no database found, you must create one!"
I then started the client and clicked on FIle/Databases/New Database

 There is a detailed tutorial of the installation on this blog written in May 2010.
