Je vous passe ma levure utilisée pour générer la configuration de mes différents domaines qui sont gérées par ma passerelle NGINX. C’est un peu comme ça que j’imagine ces fameux fichiers de config. On en trouve sur internet gérés depuis des lustres par d’autres, qu’on s’approprie, qu’on infuse à notre tour sur nos serveurs, et qu’on passe au voisin :p

Pré-requis

• Savoir installer un serveur Ubuntu
• Savoir configurer son réseau local et le NAT de son routeur
• Savoir configurer NGINX un minimum

Ma config

À la maison, ma Livebox laisse passer les connexions entrantes des ports 80, 443, 22 et 2222 uniquement. Les 2 premiers pour la partie web, les 2 suivants pour les connexions SSH de mes 2 serveurs.

Un premier serveur, que j’ai nommé « maman serveur » reçoit toutes les connexions entrantes sur les ports 80 et 443. NGINX va se charger de distribuer les appels au bon endroit :

• Mastodon, herbergé localement sur le serveur mère
• Nextcloud, herbergé sur un autre serveur fille

J’ai donc 2 fichiers de configuration, chacun va gérer un domaine dédié g33ks.coffee pour le premier et nextcloud.loicrobert.fr pour le second.

Mastodon

Ici mon fichier de configuration que j’ai trouvé en ligne et adapté à mes besoins. Modifie <domaine-vers-mastodon> avec ton domaine.

Attention dans ma configuration j’ai modifié l’adresse du dossier root pour quelle pointe vers l’emplacement personnalisé de mon dossier system de Mastodon pour les médias des membres notamment !

Nextcloud

Ci-dessous mon fichier de configuration que j’ai trouvé en ligne et adapté à ma sauce. Notamment tu devras modifier <domaine-vers-nextcloud> avec ton propre domaine, ainsi qu’adapter le proxy pass vers <adresse-ip-locale-serveur> avec l’adresse IP de ton serveur connecté à ton réseau local.

Attention cette config fonctionne si tu as au préalable installé ton Nextcloud via l’image Docker officielle configurée de façon à être derrière un proxy.

 server {

 listen       443 ssl;
 server_name  <domaine-vers-nextcloud>;
    ssl_certificate /etc/letsencrypt/live/<domaine>-0001/fullchain.pem; # managed by Certbot
   # managed by certbot on host machine
    ssl_certificate_key /etc/letsencrypt/live/<domaine>-0001/privkey.pem; # managed by Certbot
 # managed by certbot on host machine
