MISCONF Redis is configured to save RDB snapshots

redis 不能写了，查看日志报错信息如下：

MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. 
Commands that may modify the data set are disabled.
Please check Redis logs for details about the error.
Redis被配置为保存数据库快照，但它目前不能持久化到硬盘。用来修改集合数据的命令不能用。请查看Redis日志的详细错误信息

看了解决方案：

连接redis  然后执行 config set stop-writes-on-bgsave-error no

但是看到这位大佬的，感觉错误没那么简单：只是一种暂时的解决方案
