I have a CentOS 7 Server with Apache. Currently there are multiple websites hosted on Virtual Server as "Top Level Server" and "Sub-Server" using VirtualMin, i.e., Multiple Virtual Servers in Apache Webserver.
- Top-Level Server - www.example1.com (wordpress)
- Sub-Server - www.example2.com (wordpress)
- Sub-Server - www.example3.com (opencart)
- and so on..
Apache Virtual Servers:
- Default Server - /var/www/html
- Virtual Server - example1.com - /home/example1/public_html
- Virtual Server - example2.com - /home/example1/domains/example2.com/public_html
- Virtual Server - example3.com - /home/example1/domains/example3.com/public_html
I want to install LetsEncrypt SSL for all the websites. Should I install 1 SSL Certificate for all domains or 1 for each domain?
How should I proceed? Any help would be much appreciated.
