(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 fordetails about the RDB error.
解决方案：运行config set stop-writes-on-bgsave-error no 命令后，关闭配置项stop-writes-on-bgsave-error解决该问题。
bash
127.0.0.1:6379> config set stop-writes-on-bgsave-error no
OK
127.0.0.1:6379> set foo tar
OK
127.0.0.1:6379> get foo
"tar"
