Is it possible to install Ghost on a server that hosts other sites?

Hello,

This might already be answered, but I couldn’t find any info myself. I have a cheap VPS with Vultr. This VPS is running DirectAdmin as a way for me to manage all of my sites. Is it possible for me to install Ghost in this environment?

This might be obvious to some, but this is a hobby to me and I don’t have too much sysadmin knowledge yet. Any advice is appreciated!
