(error) MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

大意是：

(错误）misconf redis配置为保存RDB快照，但它当前无法在磁盘上持久。可以修改数据集的命令被禁用，因为此实例被配置为在RDB快照失败时报告写入过程中的错误（在bgsave错误选项上停止写入）。有关RDB错误的详细信息，请查看redis日志。
