How do I disable cphttpd?

Symptoms

When running a DNSOnly server, you find that the WHM still responds on port 80 with the default page, or a 404 page.

Cause 

When the cPanel DNS server is spun up, the cphttpd service is enabled and listens on port 80 so the AutoSSL service can run for your hostname. 

Resolution

1. Log in to your WHM server as the root user. 
2. Navigate to Home / Server Configuration / Terminal. 

3. Run the following.

   #  whmapi1 set_tweaksetting key='disable_cphttpd' value='1' ; /scripts/restartsrv_cpsrvd
