升级 Debian 后，启动时出现问题redis-server.service。在我的输出中，journalctl -xe我看到以下内容：

redis-server.service: Failed at step NAMESPACE spawning /usr/bin/redis-server: Stale file handle.

我无法启动 redis-server.service 并且在systemctl start redis-server我的输出中：

Job for redis-server.service failed because the control process exited with error code.
See "systemctl status redis-server.service" and "journalctl -xe" for details.

在systemctl status redis-server我的输出中：

● redis-server.service - Advanced key-value store
   Loaded: loaded (/lib/systemd/system/redis-server.service; disabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Mon 2018-01-29 10:29:08 MSK; 58s ago

我的问题是如何解决这个问题并启动 redis-server.service？

找到了解决方法：

我/lib/systemd/system/redis-server.service以 root 身份使用编辑服务文件，注释掉不同的字段，试图找出故障发生的位置并重新启动 systemd（通过systemctl daemon-reload, systemctl stop redis-server, systemctl start redis-server）

对我来说，问题是 redis-server.service 文件中的以下行：

ReadOnlyDirectories=/

我已将其注释掉并允许 redis-server 成功启动。

所以我现在/lib/systemd/system/redis-server.service是：

我刚刚在运行后遇到了这个问题，sudo apt -y dist-upgrade并得到了这个略有不同的错误/var/log/syslog

redis-server.service: Failed at step NAMESPACE spawning /usr/bin/redis-server: Invalid argument

解决方案 Launchpad Bug 1638410是：

sudo systemctl edit redis-server

[Service]
ProtectHome=no

保存退出编辑器，完成升级：

sudo apt install -f

cat /etc/os-release

如果您使用的是 Ubuntu，请在

/etc/redis/redis.conf 你应该有 ：

supervised systemd
