How to install new wordpress site to URL newsite.mydomain.com
I've done it before, I think using Softaculous, but it's been a while. Now when I start Softaculous, it asks me if I want to use a sub-directory to install the new site. This will give me a new URL mydomain.com/newWPsite.
However I want the URL newWPsite.mydomain.com. I can't figure how to do this using Softaculous. Does it mean I have to do a manual WP install? Create the new sub-directory first, then manually install WP in it? I don't remember how to go through this process, and hope to get help here.
Thank you very much for any forthcoming help.
