在Redis运行过程中，报错信息如下：
Redis::CommandError (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.)
报错信息直译：
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。
此报错大概出现原因是因为 ：
强制关闭Redis快照导致不能持久化。 Redis 运行过程中RDB快照无法写入磁盘
解决方案如下
1.进入到redis目录
cd /usr/local/redis/bin ./redis-cli
2.进入到redis客户端后分别输入
config set stop-writes-on-bgsave-error no
lpush myColour "red"
问题解决
