Impossible de démarrer nginx

Bonjour,

Je suis en train de réinstaller une nouvelle instance yunohost chez moi et pour le moment il est dans ma chambre donc je l’eteint tous les soirs pour ne pas être déranger la nuit.

Sauf qu’une fois sur 2 lors de l’allumage de mon serveur, le service ngonx ne veut pas se relancer.

Jusqu’à maintenant je m’en sortait en redémarrant le pc ou avec un sudo yunohost service restart nginx
mais aujourd’hui rien ne fonctionne…

Voila ce que j’ai comme erreur :

admin@cbft:~$ sudo service nginx status

Est ce que quelqu’un aurait une autre manip pour redemarrer le service nginx ?

Merci

Yunohost version 3.5.5
installé sur un ordinateur chez moi

Ca ressemble a une situation ou un autre serveur web utilise deja le port 80 … Est-ce que tu n’aurais pas installé Apache par exemple ?

Sinon, que raconte un netstat -tulpn | grep LISTEN | grep 80

SI je teste ta commande j’ai :
-bash: netstat : commande introuvable

Je n’ai pas installé apache volontairement mais il me semble qu’il est présent…

Tu peux tenter de l’installer avec apt install net-tools -y ?

(On est d’accord, c’est pas super intuitif :wink: )

admin@cbft:~$ sudo netstat -tulpn | grep LISTEN | grep 80
tcp 0 0 0.0.0.0:587 0.0.0.0:* LISTEN 1980/master
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1484/nginx: master
tcp 0 0 0.0.0.0:8083 0.0.0.0:* LISTEN 473/python

tcp6 0 0 :::25 :::* LISTEN 1980/master
tcp6 0 0 :::9980 :::* LISTEN 483/loolwsd

Mouarf …

et si tu fais un ps -ef --forest | grep -B5 nginx ?

admin@cbft:~$ ps -ef --forest | grep -B5 nginx

Pour info j’ai réussi à redemarrer nginx après de nombreux essai de restart mais j’aimerai bien comprendre pour les prochaines fois.

Ah ben si le probleme a de nouveau ete resolu ca sert a rien d’investiguer en l’etat …

Mais comme dit, ce que tes logs initiaux montrent, c’est qu’il y avait un autre programme qui ecoutait deja sur le port 80 … Il y peux y avoir plein de raison derriere ca…
