问题如下：
redis写入数据时报错：
(error) 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.
解决方法如下：
1、打开redis配置文件
$ sudo vi /etc/redis/redis.conf # 注意vi后面有空格在下图此行中将yes改为no，保存退出
2、指定配置加载文件
$ sudo redis-server /etc/redis/redis.conf$ redis-cli
以上就是解决redis无法写入数据的问题
