连接redis报错:
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)
redis快照被强制关闭了导致不能持久化的问题，可通过stop-writes-on-bgsave-error值设置为no即可避免这种问题
解决方法:
命令行修改:
127.0.0.1:6379> config set stop-writes-on-bgsave-error no
重启redis-server
