Plesk (or similar) admin panel for NodeJS hosting

I don't know any control panel that has NodeJS and Nginx builtin installers, but you can use Nginx and NodeJS on cPanel without any issues with or without the use of plugins.

You can install Nginx either manually, or through cPanel plugin Nginx Admin, it will allow you to control the service and vhosts trough WHM web panel.

For NodeJS install follow these steps.

Make sure that following are installed, which they should by default on cPanel servers.

GCC 4.2 or newer
Python 2.6 or 2.7
GNU Make 3.81 or newer

Download and install NodeJS

• wget http://nodejs.org/dist/node-latest.tar.gz
• tar -xvf node-latest.tar.gz
• cd node-v*
• ./configure
• make
• make install

These are the steps that work on most cPanel server.

You can find multiple NodeJS install instructions on web, here is one http://www.inmotionhosting.com/support/website/javascript/install-nodejs

Also alternative to that, you can use nDeploy, also cPanel plugin, but not a free one. I haven't tried it, but according to their site, it is "cpanel nginx plugin that lets you deploy PHP/Ruby/Python/NodeJS/ColdFusion and more!"
