#最大可用内存  

maxmemory 10g  

#内存耗尽时采用的淘汰策略:  

# volatile-lru -> remove the key with an expire set using an LRU algorithm  

# allkeys-lru -> remove any key accordingly to the LRU algorithm  

# volatile-random -> remove a random key with an expire set  

# allkeys-random -> remove a random key, any key  

# volatile-ttl -> remove the key with the nearest expire time (minor TTL)  

# noeviction -> don't expire at all, just return an error on write operations

#部署在同一机器的redis实例，把auto-aof-rewrite搓开，因为cluster环境下内存占用基本一致.  

#防止同一机器下瞬间fork所有redis进程做aof rewrite,占用大量内存(ps:cluster必须开启aof)
