How to Configure Apache Virtualhost so Floating IP will work with multiple domains on one droplet?
I set up a floating IP on my droplet. My droplet uses Apache Virtual Hosts to host multiple domains. One of my domains works fine, as it should after I change the A Record to point to the Floating IP (the same domain that is shown when I type with my default ipv4 IP number into a browser).
However, when I change the A record for each of the other domains in my droplet and point them to the Floating IP, the sites stop working. Is there a .config file that I need to modify for each of my domains virtual host?
My reason for wanting to use the Floating IP instead of the ipv4 IP is so I could easily switch traffic to another droplet without having to wait for DNS records to propogate. This works beautifully on the main site but not on the other sites created via Apache Virtual Hosts.
By the way, I am using Ubuntu 14.04 and want to have this working fine before I switch the Floating IP number to point to a new Ubuntu 18.04 droplet with a similar configuration.
