When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com, example2.com, and example1.com/images on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers

This process requires that you are able to ssh OR log in locally using the root user account and that no services be running as users out of /home on the target machine.
The examples are from a default installation with no customization-you NEED to know what you're working with for volumes/partitions to not horribly break things.
By default, CentOS 7 uses XFS for the file system and Logical Volume Manager (LVM), creating 3 partitions: /,/home and swap.
NOTE: If you want to be sure that nothing is writing to /home you can either modify the host to boot into single-user mode OR try to use the
systemctl isolate runlevel1.target command to switch (not tested! should work).
