Question

我已从17.10升级到ubuntu 18.04。无法完全安装redis-server软件包。我查看了/ var / log / syslog，它说

然而它超时并没有启动redis deamon。配置文件是包附带的配置文件。

我尝试手动创建pid文件并赋予它很多权限。但这似乎不起作用。

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/

Answer 1

我找到了罪魁祸首。我暂时禁用了ipv6。我把它重新打开并且安装得很好并且启动正常。您可以更改redis.conf文件以强制它使用IPv4，如果它仅支持该模式，那么也许您可以在没有IPv6的情况下运行它。

Answer 2

即使禁用了IPv6，也可以使redis服务器运行。

只需从::1配置选项中删除bind IPv6回送地址：

- bind 127.0.0.1 ::1
+ bind 127.0.0.1

现在redis将不再尝试使用IPv6网络。

Answer 3

嗯，从Ubuntu 16.04升级到18.04只是一个类似的问题。上面的解决方案（禁用ipv6）在这里没有帮助。可能是我，但是我也不明白为什么这样做会有所帮助，因为错误的重要部分似乎是

# First we create an empty Byte-Pair Encoding model (i.e. not trained model)
tokenizer = Tokenizer(BPE())
tokenizer.normalizer = Sequence([
    NFKC(),
    Lowercase()
])

显然，创建文件本身并不一定能解决该问题。但是，有帮助的是创建目录并授予其必要的权限：

Jun  3 13:05:40 qaz-mko systemd[1]: redis-server.service: Can't open PID file /var/run/redis/redis-server.pid (yet?) after start: No such file or directory

它不会在重启后持续存在。尽管我仍在努力寻找解决方案，但快速而肮脏的解决方法是将上述代码行放入rc.local
