Using Discourse With Other Sites on Same Droplet

Hey guys,

I am new to discourse and do not have a development related background. I was just trying discourse and have successfully installed it on a droplet at digitalocean. This is the step by step tutorial that I followed:

Now I would like to add my other WordPress blogs to the same hosting account on digitalocean. I know I can add domain names to my droplet by visiting DNS settings. But the URL I want to use for the discourse site is already pointing to my server’s IP address.

Is there something that I need to change so that my discourse site’s domain only points to discourse and I can add other sites too?
