Redis 是完全开源免费的，遵守BSD协议，是一个高性能的key-value数据库。
Redis 与其他 key - value 缓存产品有以下三个特点：
Redis支持数据的持久化，可以将内存中的数据保存在磁盘中，重启的时候可以再次加载进行使用。
Redis不仅仅支持简单的key-value类型的数据，同时还提供list，set，zset，hash等数据结构的存储。
Redis支持数据的备份，即master-slave模式的数据备份。
一、yum install redis 安装
[root@localhost ~]# yum install redis

二、 redis-server -v 检查安装版本
[root@localhost ~]# redis-server -v
Redis server v=3.2.12 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=3dc3425a3049d2ef
三、service redis start 启动redis
[root@localhost ~]# service redis start
Redirecting to /bin/systemctl start redis.service
四、chkconfig redis on 设置开机自启动
[root@localhost ~]# chkconfig redis on
Note: Forwarding request to 'systemctl enable redis.service'.
Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /usr/lib/systemd/system/redis.service.
五、验证是否加入开机自启动列表
[root@localhost ~]# systemctl list-unit-files
...
...
redis.service enabled
...
六、高级设置
自行google一波
七、安装php-redis扩展
- 查看支持插件支持
[root@localhost ~]# yum list php71w-pecl-redis*
