Linux----redis群集

                                                                 （实验准备redis软件包和redis-gem包）

• set：存放数据，基本格式：set key value
• get：获取数据，基本格式：get key
• 

*共计最少6台虚拟机登录数据库，使用redis-cli命令
   #redis-cli
   #redis-benchmark -h 192.168.1.1 -p 6379 -c 100 -n 100000
   #redis-benchmark -h 192.168.1.1 -p 6379 -q -d 100
  # redis-benchmark -t set,lpush -n 100000 -q

redis数据库常用命令
   set   存放数据
   get  获取数据
   rename    重命名
   del          删除
   select      多数据库切换如：127.0.0.1：6379[10]>切换到序号10的数据库
   move      移动 将10数据库的1移动到2中

在6台centos中安装redis，修改配置文件，启用群集功能
(1)复制redis包到所有主机的/usr/src下
(2)通过脚本安装并配置群集redis
