原因
是因为强制把redis快照关闭了导致不能持久化的问题，在网上查了一些相关解决方案，通过stop-writes-on-bgsave-error值设置为no即可避免这种问题。 有两种修改方法，一种是通过redis命令行修改，另一种是直接修改redis.conf配置文件1. 命令行方式
命令行修改方式示例：127.0.0.1:6379> config set stop-writes-on-bgsave-error no
2. 修改配置文件
修改redis.conf文件：vi打开redis-server配置的redis.conf文件，然后使用快捷匹配模式：/stop-writes-on-bgsave-error定位到stop-writes-on-bgsave-error字符串所在位置，接着把后面的yes设置为no即可。正文到此结束
