### 本地数据库的目录

save 900 1
save 300 10
save 60 10000

执行shutdown默认保存了一次

vi /opt/redis_cluster/redis_6379/conf/redis_6379.conf
#是否打开aof日志功能
appendonly yes
# 每一个都立即同步到aof
appendfsync always
#每秒写一次
appendfsync everysec
#写入工作交给操作系统，由操作系统判断缓冲区大小，统一写入到aof
appendfsync no
appendfilename "appendonly.aof"

两个文件都存在，aof起作用
