The Odoo configuration file can be found at /etc/odoo/odoo.conf; open the configuration file using the gedit editor with the following command:
Set admin_passwd, which is the master password for managing databases from the Odoo interface. The second parameter to be added is the workers parameter; I set it to 5, as my server has two cores. The workers can be set based on the following calculation:
Workers = (2 * number or core) + 1
Restart the Odoo service after changing any parameters to the configuration file.
