今天执行redis命令：move key22 2 时，报如下错误：
(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.
中文解释：
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。
原因：强制关闭Redis快照导致不能持久化。
解决方案：
将stop-writes-on-bgsave-error设置为no
命令如下：
127.0.0.1:6379> config set stop-writes-on-bgsave-error no
OK
