Create the "Web Reader" Export
First create the web reader export that will then generate a set of HTML files.
Put files on web server
Place the set of files generated by the export on any type of web server.
If your location is /issues/issue32/ then navigating to http://[domain.com]/issues/issue32 should display the index page of your publication.
The "Web Reader" export always creates a single-issue publication. If you have specific requirements with e.g. restricted access for subscribers, or if you want to create your own store for desktop and notebook users, then you can use an authentication page or put your publications behind a paywall.
