前言：
集群是指通过添加服务器的数量，提供相同的服务，从而让如武器达到一个稳定、高效的状态。为什么要使用redis集群呢？redis集群可以强化的redis的读写能力。
下面我们就来正式学习下redis集群。
准备工作：
需要4个部件：redis、ruby语言运行环境、redis的ruby驱动redis-xxxx.gem、创建redis集群的工具redis-trib.rb。使用redis-trib.rb工具来创建redis集群，由于该文件是用ruby语言写的，所以需要安装ruby开发环境，以及驱动redis-xxxx.gem。
1）下载redis安装文件：https://github.com/msopentech/redis/releases/，redis提供msi和zip格式的下载文件，这里下载zip格式redis-x64-3.2.100版本。
2）下载ruby安装文件：http://dl.bintray.com/oneclick/rubyinstaller/rubyinstaller-2.2.4-x64.exe
3）下载ruby环境下redis的驱动：https://rubygems.org/gems/redis/versions/3.2.2，考虑到兼容性，这里下载的是3.2.2版本
注意：下载在页面右下角相关连接一项中
4）下载redis官方提供的创建redis集群的ruby脚本文件redis-trib.rb，路径如下：https://raw.githubusercontent.com/msopentech/redis/3.0/src/redis-trib.rb
安装redis
将下载到的redis-x64-3.2.100.zip解压即可，为了方便使用，建议放在盘符根目录下，如：d:\redis-cluster\redis-x64-3.2.100。 
安装redis，并运行3个实例(redis集群需要至少3个以上节点，低于3个无法创建)；
通过配置文件来启动6个不同的redis实例，由于redis默认端口为6379，所以这里使用了6380、6381、6382、6383、6384、6385来运行6个redis实例。
注意：
（1）为了避免不必要的错误，配置文件尽量保存为utf8格式，并且不要包含注释；
（2）配置文件中以下两种保存日志的方式(保存在文件中、保存到system log中)请根据需求选择其中一种即可：
loglevel notice #日志的记录级别，notice是适合生产环境的logfile "d:/redis-cluster/redis-x64-3.2.100/logs/redis6380_log.txt" #指定log的保持路径,默认是创建在redis安装目录下，如果有子目录需要手动创建，如此处的logs目录syslog-enabled yes #是否使用系统日志 syslog-ident redis6380 #在系统日志的标识名
这里使用了保存在文件中的方式，所以先在redis目录d:\redis-cluster\redis-x64-3.2.100下新建logs文件夹。
在redis安装根目录下，创建编码格式为utf-8的配置文件：redis.6380.conf、redis.6381.conf、redis.6382.conf、redis.6383.conf、redis.6384.conf、redis.6385.conf。
redis.6380.conf、
port 6380 loglevel notice logfile "d:/redis-cluster/redis-x64-3.2.100/logs/redis6380_log.txt" appendonly yesappendfilename "appendonly.6380.aof" cluster-enabled yes cluster-config-file nodes.6380.confcluster-node-timeout 15000cluster-slave-validity-factor 10cluster-migration-barrier 1cluster-require-full-coverage yes

redis.6383.conf、

redis.6384.conf、
port 6384 loglevel notice logfile "d:/redis-cluster/redis-x64-3.2.100/logs/redis6384_log.txt" appendonly yesappendfilename "appendonly.6384.aof" cluster-enabled yes cluster-config-file nodes.6384.confcluster-node-timeout 15000cluster-slave-validity-factor 10cluster-migration-barrier 1cluster-require-full-coverage yes

配置解释如下：
port 6380 #端口号loglevel notice #日志的记录级别，notice是适合生产环境的logfile "logs/redis6380_log.txt" #指定log的保持路径,默认是创建在redis安装目录下，如果有子目录需要手动创建，如此处的logs目录syslog-enabled yes #是否使用系统日志syslog-ident redis6380 #在系统日志的标识名appendonly yes #数据的保存为aof格式appendfilename "appendonly.6380.aof" #数据保存文件cluster-enabled yes #是否开启集群cluster-config-file nodes.6380.confcluster-node-timeout 15000cluster-slave-validity-factor 10cluster-migration-barrier 1cluster-require-full-coverage yes
将上述配置文件保存到redis目录下，并使用这些配置文件安装6个redis服务，命令如下：
d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-install d:/redis-cluster/redis-x64-3.2.100/redis.6380.conf --service-name redis6380d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-install d:/redis-cluster/redis-x64-3.2.100/redis.6381.conf --service-name redis6381d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-install d:/redis-cluster/redis-x64-3.2.100/redis.6382.conf --service-name redis6382d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-install d:/redis-cluster/redis-x64-3.2.100/redis.6383.conf --service-name redis6383d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-install d:/redis-cluster/redis-x64-3.2.100/redis.6384.conf --service-name redis6384d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-install d:/redis-cluster/redis-x64-3.2.100/redis.6385.conf --service-name redis6385
注意：
1）redis.6380.conf等配置文件最好使用完整路径，避免重启redis集群出现问题
2）卸载命令为：
d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-uninstall d:/redis-cluster/redis-x64-3.2.100/redis.6380.conf --service-name redis6380d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-uninstall d:/redis-cluster/redis-x64-3.2.100/redis.6381.conf --service-name redis6381d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-uninstall d:/redis-cluster/redis-x64-3.2.100/redis.6382.conf --service-name redis6382d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-uninstall d:/redis-cluster/redis-x64-3.2.100/redis.6383.conf --service-name redis6383d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-uninstall d:/redis-cluster/redis-x64-3.2.100/redis.6384.conf --service-name redis6384d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-uninstall d:/redis-cluster/redis-x64-3.2.100/redis.6385.conf --service-name redis6385
启动这6个服务，命令如下：
d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6380d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6381d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6382d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6383d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6384d:/redis-cluster/redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6385
执行结果：
安装ruby
（1）ruby环境安装。
双击下载的“rubyinstaller-2.2.4-x64.exe”安装即可，同样，为了操作方便，也是建议安装在盘符根目录下，如： c:\ruby22-x64 ，安装时这里选中后两个选项，
意思是将ruby添加到系统的环境变量中，在cmd命令中能直接使用ruby的命令
（1）安装ruby环境下redis的驱动
将下载的"ruby环境下redis的驱动文件(redis-3.2.2.gem)"拷贝到ruby安装根目录（c:\ruby22-x64）下。
然后执行安装命令如下：
gem install --local path_to_gem/filename.gem
创建redis集群
将下载的“创建redis集群的ruby脚本文件redis-trib.rb”文件拷贝到redis安装根目录(d:\redis-cluster\redis-x64-3.2.100)下。
（1）使用redis-trib.rb来创建redis集群
md下切换到redis目录(d:\redis-cluster\redis-x64-3.2.100)

备注：
（1）--replicas #指定集群中每个主节点配备几个从节点，这里设置为1。
（2）redis-trib.rb工具的使用
、create：创建集群、check：检查集群、info：查看集群信息、fix：修复集群、reshard：在线迁移slot、rebalance：平衡集群节点slot数量、add-node：将新节点加入集群、del-node：从集群中删除节点、set-timeout：设置集群节点间心跳连接的超时时间、call：在集群全部节点上执行命令、import：将外部redis数据导入集群
（2）检验是否真的创建成功
输入以下命令：
redis-trib.rb check 127.0.0.1:6380
如果现实信息如下，则说明创建的redis集群是没问题。
d:\redis-cluster\redis-x64-3.2.100>redis-trib.rb check 127.0.0.1:6380connecting to node 127.0.0.1:6380: okconnecting to node 127.0.0.1:6383: okconnecting to node 127.0.0.1:6382: okconnecting to node 127.0.0.1:6384: okconnecting to node 127.0.0.1:6385: okconnecting to node 127.0.0.1:6381: ok>>> performing cluster check (using node 127.0.0.1:6380)m: bb6ef615bb0ae13275943caec0db9d30b9f35c5e 127.0.0.1:6380 slots:0-5460 (5461 slots) master 1 additional replica(s)s: 5d154137180284d926ef51a91fc75f9438249ef8 127.0.0.1:6383 slots: (0 slots) slave replicates bb6ef615bb0ae13275943caec0db9d30b9f35c5em: 837779b3965e2c9d4dd4385750aaaaf9a9039fb0 127.0.0.1:6382 slots:10923-16383 (5461 slots) master 1 additional replica(s)s: ad151680a3e36cf2083ef822be0bdb075a7d36de 127.0.0.1:6384 slots: (0 slots) slave replicates b4d120f2983ad683f7b68992e1ba414722238db7s: 9a2260a5a6a2add84b622a453a6a7b86a29d180d 127.0.0.1:6385 slots: (0 slots) slave replicates 837779b3965e2c9d4dd4385750aaaaf9a9039fb0m: b4d120f2983ad683f7b68992e1ba414722238db7 127.0.0.1:6381 slots:5461-10922 (5462 slots) master 1 additional replica(s)[ok] all nodes agree about slots configuration.>>> check for open slots...>>> check slots coverage...[ok] all 16384 slots covered.d:\redis-cluster\redis-x64-3.2.100>
（3）信息查询
使用redis客户端redis-cli.exe来查看数据记录数，以及集群相关信息
