Restart the postgresql service

	systemctl restart postgresql-9.4

##Install Odoo

		nano /etc/odoo/openerp-server.conf
		
		admin_passwd = YourPassword


- Restart Odoo for the changes to take effect

##Finally

Now, open a web browser and access Odoo 9 at http://yourIPaddress:8069 to create a new PostgreSQL database and set password for the admin user.
