|

|

This script will install SSL from Let's Encrypt.
|
||||
It's free of charge, and very easy to maintain.
|
||||
|
||||
Before we begin the installation you need to have
|
||||
a domain that the SSL certs will be valid for.
|
||||
If you don't have a domain yet, get one before
|
||||
you run this script!
|
||||
|
||||
You also have to open port 80+443 against this VMs
|
||||
IP address: $ADDRESS - do this in your router/FW.
|
||||
Here is a guide: https://goo.gl/Uyuf65
|
||||
|
||||
You can find the script here: $SCRIPTS/activate-ssl.sh
|
||||
and you can run it after you got a domain.
|
||||
|
||||
Please don't run this script if you don't have
|
||||
a domain yet. You can get one for a fair price here:
|
||||
https://store.binero.se/?lang=en-US"
