Redis 指令备忘清单（超级详细！）
本备忘单旨在快速理解 redis 所涉及的重要概念，提供了最常用的SQL语句，供参考。入门
介绍
Redis 是一个 key-value 存储体系类似 Memcached
[*]它支持存储的 value 类型相对更多，包括string(字符串)、list(链表)、set(集合)、zset(sorted set 有序集合)和hash(哈希类型)
[*]数据类型都支持 push/pop、add/remove 及取交集并集和差集及更丰富的操纵
启动 Redis
$ redis-server &
使用 CLI 登陆 redis
$ redis-cli
使用 Telnet 的登陆 redis
$ telnet 127.0.0.1 6379
小试
Ping 测试
redis> PING
