2、file nodes-7006.conf启动服务打开6个CMD命令行工具,切换到C:redis-64.3.0.503目录下，分别输入Redis-server.exe redis.7001.confRedis-server.exe redis.7002.confRedis-server.exe redis.7003.confRedis-server.exe redis.7004.confRedis-server.exe redis.7005.confRedis-server.exe redis.7006.conf启动成功后界面如下3. Ruby安装下载地址：安装界面如下所示安装完成后，打开命令输

3、入ruby v命令检查是否安装成功4. 安装redis的ruby运行库打开命令行输入gem install redis命令5. 下载redis-trib.rb脚本文件redis-trib.rb文件是运行redis集群的脚本库,文件内容如下,可将下面的文件内容拷贝到记事本中另存为redis-trib.rb文件然后将redis-trib.rb拷贝到C:redis-64.3.0.503目录下#!/usr/bin/env ruby# TODO （temporary here, well move this into the Github issues once# redis-trib initial

4、implementation is completed）.# - Make sure that if the rehashing fails in the middle redis-trib will try# to recover.# - When redis-trib performs a cluster check, if it detects a slot move in# progress it should prompt the user to continue the move from where it# stopped.# - Gracefully handle Ctrl+C

5、 in move_slot to prompt the user if really stop# while rehashing, and performing the best cleanup possible if the user# forces the quit.# - When doing fix set a global Fix to true, and prompt the user to# fix the problem if automatically fixable every time there is something# to fix. For instance:#

6、1） If there is a node that pretend to receive a slot, or to migrate a# slot, but has no entries in that slot, fix it.# 2） If there is a node having keys in slots that are not owned by it# fix this condition moving the entries in the same node.# 3） Perform more possibly slow tests about the state of
