Redis Enable persistence

The persistence of redis has two species of Rdb and aof.
RDB is a record of the operation over a period of time, a disk configuration is more than a period of time the operation of the persistence of more than a few times.
AOF enables you to persist each operation.
Here we use AOF.

Configuration, open the Redis configuration file. Find AppendOnly. The default is AppendOnly No. Change into appendonly yes.

and find Appendfsync.
The default is: # Appendfsync always #每次收到写命令就立即强制写入磁盘, slowest, but guaranteed to be completely persistent, not recommended for use with Appendfsync everysec #每秒钟强制写入磁盘一次, well done in terms of performance and persistence The compromise, recommended # Appendfsync No #完全依赖os, best performance, no guarantee of permanence
