How to create a subdomain with SiteWorx

This article shows how Nexcess clients on physical (non-cloud) servers can use SiteWorx to create a subdomain. 

ATTENTION: This method works only for Nexcess clients on physical (non-cloud) servers. If you are a Nexcess Cloud client, see instead How to create secondary domains in Nexcess Cloud.

Use the below procedure if you want the subdomain to use a directory separate from that of the main domain. You may create this subdomain from the SiteWorx control panel, which will create a folder at /home/username/<your_subdomain>.

A subdomain will share the web root, or document root, with the main domain. The vhost file for the main domain will then translate this into the subdomain as This in turn allows the subdomain to duplicate the main domain's server configurations and SSLs.


  1. Log in to your SiteWorx account.

  2. On the main menu, click Hosting Features > Domains > Subdomain.

  3. In the Subdomain field, type your subdomain name. Click Add when ready.
