(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.
127.0.0.1:6379> config set stop-writes-on-bgsave-error no


翻译出来:

(错误)错误的Redis配置为保存RDB快照,但当前无法在磁盘上持久化。禁用可能修改数据集的命令,因为此实例配置为在RDB快照失败时报告写入期间的错误(在bgsave error选项上停止写入)。有关RDB错误的详细信息,请查看Redis日志。

解决:redis命令行中运行

config set stop-writes-on-bgsave-error no
