redis出现错误，页面一片空白

这两天遇到了一个问题，网页间接性的出现一片空白的现象，通过查找写入状态发现

Fatal error: Uncaught RedisException: 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. in

通过百度找到解决办法，在redis配置里，搜索

stop-writes-on-bgsave-error

设置成 

stop-writes-on-bgsave-error on
