Let’s encrypt is a non-profit organization certificate authority established to provide SSL. Their service completely free of cost. The certificates are valid for 3 months, but we can automate the renewal process.
Before doing this, please note that following things need to be replaced by relevant values. I don’t think it needs further explanation.
- MyServerName
- MyAdminEmailAddress
- MyServerAddress
This is tested on Ubuntu 14.04 server running Odoo 9.

First we need to install the Apache2 server. If you already running it, good – skit these.
