Next go to the /opt/odoo14 directory and create Python virtual environment for the Odoo installation.

deactivate && exit

We will create a new directory for the custom modules and change its ownership to odoo14 user.

mkdir /opt/odoo14/odoo-custom-addons
chown -R odoo14:odoo14 /opt/odoo14/odoo-custom-addons

next, to create a configuration file for the Odoo instance.

sudo nano /etc/odoo14.conf

[options]
; This is the password that allows database operations:
admin_passwd = Strong_admin_passwd
db_host = False
db_port = False
db_user = odoo14
db_password = False
addons_path = /opt/odoo14/odoo/addons, /opt/odoo14/odoo-custom-addons

save the file and exit.
