ubuntu 18.04にredis-serverをインストールできません

17.10。からubuntu 18.04にアップグレードしました。 redis-serverパッケージを完全にインストールすることはできません。/var/log/syslogを見たところ、

ただし、タイムアウトになり、Redisデーモンは開始されません。構成ファイルは、パッケージに付属しているものです。

Pidファイルを手動で作成し、多くのアクセス許可を与えてみました。しかし、それはうまくいかないようです。

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

犯人を見つけました。しばらく前にipv6を無効にしていました。電源を入れ直すと、問題なくインストールされ、問題なく起動しました。おそらくredis.confファイルを変更して、IPv4がそのモードのみをサポートしている場合、強制的にIPv4を使用することができます。その後、IPv6なしで実行できます。

IPv6が無効になっている場合でも、redis-serverを実行することができます。

単に::1bind configオプションからのIPv6ループバックアドレス：

- bind 127.0.0.1 ::1
+ bind 127.0.0.1

これで、redisはIPv6ネットワークの使用を試行しなくなります。
