[RESOLU] apache2 ne répond plus ; La connexion a échouée

Bonjour,
Après quelques semaines de bons et loyaux services, mon serveur apache refuse le service.
localhost dans firefox me retourne : La connexion a échouée.
J'ai désinstallé et réinstallé plusieurs fois apache2 ; c'est toujours pareille. J'ai trouvé ailleurs un post qui parle de ce pb et j'ai suivi les conseils de test. Voici ce que ça me donne. À la fin j'ai mis le contenu de  /etc/init.d/apache2 qui semble en cause (du peu que je comprend, je suis newbee dans ce domaine) :-((

Re : [RESOLU] apache2 ne répond plus ; La connexion a échouée

Ouuuuuuuuuuufffffffffffff ! ça y est !
Finalement en faisant ceci:
J'ai dégagé les dossiers sous /var/www/html (bien que je ne voie pas le rapport)
Puis :
sudo apt remove apache* mysql-server* php*
puis ça :
sudo apt-get install lamp-server^
ET ÇA MARCHE !

si ça peut servir ....
