#& patches by doing an update
#
sudo apt-get update

#
sudo apt-get install openssh-server denyhosts
#
#Create User
#
echo "Enter The Openerp Username"
read user
sudo adduser --system --home=/opt/$user --group $user
#
#Make Sure that Postgresql is installed on the system
#
sudo apt-get -y install postgresql
#

echo "restart postgresql"
echo "open erp is started"


After the script ran completely add a user in postgresql with same name as you have mention in the script and you are ready to go.

Thanks..
