重启redis后，设置值时报错：(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.
报错截图：
原因是因为强制把redis快照关闭了导致不能持久化！
把stop-writes-on-bgsave-error值设置为no即可：
进入src文件夹：
输入./redis-cli，进入redis
输入：config set stop-writes-on-bgsave-error no


也可以直接修改redis.conf文件。
解决！
