摘要：AOF将所有的命令写入文件中，相关于MYSQL的BINLOG文件运行原理:从主进程中fork一个子进程，这个子进程来将执行过的命令写入一个文件中可以通过压缩算法来减少存储文件的大小 打开AOF功能:vim /etc/redis326/6379.confvim 6379.conf  596 appendonlyyes 597  598 # The nameof the append only file (default: "appendonly.aof") 599 &

摘要：缺点：每次保存都要fork一个子进程，如果数据量大小，会有延时恢复数据的时间短 优点：备份方便 打开RDB功能:vim /etc/redis326/6379.confvim 6379.conf#以下三条是或的关系 204 save 900 1             #在900秒内有1个key发生变化，就做一次快照 205 save 300 10    &
