Question

升级Debian后，它出现问题redis-server.service。在journalctl -xe的输出中，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并在systemctl start redis-server的输出中启动：

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的输出中，我有：

● 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

我的问题如何解决此问题并启动redis-server.service？

Answer 1

找到解决方案解决方案：

我以root身份使用/lib/systemd/system/redis-server.service编辑服务文件，注释掉了尝试查找失败位置的不同字段并重新启动systemd（通过systemctl daemon-reload，systemctl stop redis-server，{ {1}}）

对我来说，问题是redis-server.service文件中的以下行：

systemctl start redis-server

我已经注释掉了，并且允许redis-server成功启动。

所以我当前的ReadOnlyDirectories=/是：

/lib/systemd/system/redis-server.service

Answer 2

我在运行sudo apt -y dist-upgrade后刚遇到此问题，并且在/var/log/syslog中遇到了这个略有不同的错误

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

保存并退出编辑器并完成升级：

sudo apt install -f

cat /etc/os-release

如果您使用的是Ubunut，则

/etc/redis/redis.conf 您应该有：

supervised systemd

Redis无法启动时出现错误：redis-server.service：步骤NAMESPACE生成失败/ usr / bin / redis-server：过时的文件句柄
