impossible d'installer redis-server sur ubuntu 18.04

Je suis passé à ubuntu 18.04 à partir de 17.10. Le package redis-server ne peut pas être entièrement installé. J'ai regardé/var/log/syslog et ça dit

Cependant, il expire et ne démarre pas le démon redis. Le fichier de configuration est celui fourni avec le package.

J'ai essayé de créer le fichier pid à la main et de lui donner beaucoup d'autorisations. Mais cela ne semble pas fonctionner.

Sudo touch /var/run/redis/redis-server.pid
# Sudo chown redis:redis /var/run/redis/redis-server.pid
# Sudo chmod 777 /var/run/redis/redis-server.pid
# Sudo ls -alh /var/run/redis/

J'ai trouvé le coupable. J'avais désactivé ipv6 il y a quelque temps. Je l'ai rallumé et il s'est bien installé et a bien démarré. Vous pouvez probablement modifier le fichier redis.conf pour le forcer à utiliser IPv4 s'il ne prend en charge que ce mode et peut-être pourriez-vous l'exécuter sans IPv6.

Il est possible de faire fonctionner redis-server même lorsque IPv6 est désactivé.

Retirez simplement le ::1 Adresse de bouclage IPv6 depuis l'option de configuration bind:

- bind 127.0.0.1 ::1
+ bind 127.0.0.1

Maintenant, redis n'essaiera pas d'utiliser le réseau IPv6.
