无法在 ubuntu 18.04 上安装 redis-server

Question

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

然而，它超时并且不会启动 redis 守护程序。 配置文件是 package 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

即使禁用了 IPv6，也可以让 redis-server 运行。

只需从bind配置选项中删除::1 IPv6 环回地址（默认位于/etc/redis/redis.conf ）：

- bind 127.0.0.1 ::1
+ bind 127.0.0.1

现在 redis 不会尝试使用 IPv6 网络。

Answer 2

我找到了罪魁祸首。 不久前我禁用了 ipv6。 我重新打开它，它安装正常并且启动正常。 如果 redis.conf 文件仅支持该模式，您可能会更改它以强制它使用 IPv4，然后也许您可以在没有 IPv6 的情况下运行它。

Answer 3

我也没有安装 redis-server，在尝试了很多方法之后，我能够按照以下步骤使用 Ubuntu 在 Windows 上安装它：

sudo apt-add-repository ppa:redislabs/redis
sudo apt-get update

然后确保你安装了 redis-tools & libglib2.0-0。 如果没有，请安装这些：

sudo apt-get install redis-tools
sudo apt-get install -y libglib2.0-0

下一个：

sudo apt-get install redis-server

然后像这样启动 Redis 服务器：

sudo service redis-server start

Answer 4

好吧，我刚刚从 Ubuntu 16.04 升级到 18.04 时遇到了类似的问题。 上面的解决方案（禁用 ipv6）在这里没有帮助。 很可能是我，但我也不明白为什么这会有所帮助，因为错误的重要部分似乎是

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

显然，创建文件本身并不一定能解决这个问题。 但是，有什么帮助是创建目录并为其授予必要的权限：

mkdir -p /var/run/redis
chown redis:redis /var/run/redis

它不会在重新启动后持续存在。 虽然我仍在尝试为此找到解决方案，但快速而肮脏的解决方法是将上述行放入 rc.local

可能从 systemd 单元中删除 PID /etc/systemd/system/redis-cluster-node@.service 可以提供帮助
