Сделать мой сервер Apache2 общедоступным

Я действительно запутался, как сделать свой веб-сервер Apache2 общедоступным. Я настроил все, и когда я набираю localhost:80, он подходит правильно. Но мне нужны очень четкие и подробные инструкции о том, как сделать его общедоступным! А также использовать его псевдоним, который я установил для pcpcpc12.com
