redis是当前比较热门的NOSQL系统之一，它是一个key-value存储系统。和Memcached类似，但很大程度补偿了memcached的不足，它支持存储的value类型相对更多，包括string、list、set、zset和hash。这些数据类型都支持push/pop、add/remove及取交集并集和差集及更丰富的操作。在此基础上，redis支持各种不同方式的排序。Redis数据都是缓存在计算机内存中，并且会周期性的把更新的数据写入磁盘或者把修改操作写入追加的记录文件。

版本:3.0.2

下载地址:http://download.redis.io/releases/redis-3.0.2.tar.gz

下载完以后,放在/home目录下

[root@localhost home]# tar -zxvf redis-3.0.2.tar.gz

附:我把名字默认目录redis-3.0.2 改为redis

[root@localhost home]# cd redis

[root@localhost redis]# make

启动 redis 与之前版本不一样, redis的启动放在src下

[root@localhost src]# ./redis-server ../redis.conf
