由于本地环境的使用,所以搭建一个本地的 Redis 集群,本篇讲解 Redis 主从复制集群的搭建,使用的平台是 Windows。为了使得集群在一部分节点下线或者无法与集群的大多数节点进行通讯的情况下, 仍然可以正常运作, Redis 集群对节点使用了主从复制功能: 集群中的每个节点都有 1 个至 N 个复制品(replica), 其中一个复制品为主节点(master), 而其余的 N-1 个复制品为从节点(slave)。

Why Redis beats Memcached for caching 有更新!

These renowned cache engines share a number of similarities, but they also have important differences. Redis, the newer and more versatile of the two, is almost always the superior choice.
