How to install SSL to other port, like 8001 for using with Secure Web Sockets?

Via SSH..

Code:

cd /var/cpanel

Then:

Code:

sudo vi cpanel.config

After that:
Change "apache_ssl_port=0.0.0.0:443" to "apache_ssl_port=0.0.0.0:new_port" (Replace new_port with your port number)

Finally, run:

Code:

sudo /usr/local/cpanel/whostmgr/bin/whostmgr2 --updatetweaksettings

I think this will work. I've never needed to do it, personally.

Good luck.
