redis - "Redis is configured to save RDB snapshots"错误，与权限/内存/磁盘空间无关

Question

我收到以下 Redis 错误:

MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk.

不过，这与权限无关，因为它只会在重启后的特定时间开始出现(最近一次出现是在重启后大约一天)。当它发生时，服务器有足够的内存和磁盘空间。有什么建议么？谢谢。

编辑:Redis 日志在正确保存时显示:

错误发生时:

Answer 1

我们遇到了同样的问题，结果证明有人“破解”了我们的服务器并将临时数据库路径更改为“.ssh”并将文件名更改为“authorized_keys”。我们在 redis CLI 中使用了以下命令来更改它们:

CONFIG SET dir /original/tmp/directory
CONFIG SET dbfilename temp.rdb

希望这对您有所帮助!
