Redis实例安装

安装说明：自动解压缩安装包，按照指定路径编译安装，复制配置文件模板到Redis实例路的数据径下，根据端口号修改配置文件模板

配置文件，当前shell脚本，安装包

参数1：basedir,redis安装包路径

参数2：安装实例路径

参数3：安装包名称

参数4：安装实例的端口号

Redi实例的目录结构

基于Python的Redis自动化集群实现

基于Python的自动化集群实现，初始化节点为node_1~node_6，节点实例需要为集群模式，三主三从，自动化集群，分配slots，加入从节点，3秒钟左右完成

import redis

示例

这样一个Redis的集群，从实例的安装到集群的安装，环境依赖本身没有问题的话，基本上1分钟之内可以完成这个搭建过程。
