I think you need to thoroughly know Apache before removing any of these modules. If you follow the manual to install Apache for Moodle as Ken mentioned (https://docs.moodle.org/36/en/Apache) I think you'll already be able to run Moodle without problems. Further tuning and configuration depends on number of concurrent users and performance and security requirements. Hope this helps you to make a start.
