Setting up multiple sites under your domain is a important thing if you want to serve different content or even use a different CMS per site. We do this for our sites, this community is running on N5 as a different site then our blog on N7. We even use different systems on each.
This is easy to setup so we will create one for
hello.nodehost.ca. Just create a new site container just like you would if you created a new site. Now you have a blank site container to work with, now let's add the domain.
Instead if putting your main domain you enter the sub domain you want to use, remember to also include the full domain attached to the sub domain. We will use
hello.nodehost.ca for this. Once added it should look like the following image.
Now just go and edit your dns on your domain provider or CloudFlare or even a different site on NodeHost and enter the new sub domain as a A record (or CNAME). Include a
www.hello record also or delete it as an alias from the site.
Now you are all setup and you should be able to load your new site.
