在Windows系统下搭建Redis集群

2022-10-04 15:50:08

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。

在Windows系统下搭建Redis集群

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。

cluster-enabled yes

cluster-config-file nodes..conf

cluster-node-timeout

配置解释如下：

 port                                  #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

 cluster-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 redis6380

D:/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 redis6381

D:/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 redis6382

D:/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 redis6383

D:/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 redis6384

D:/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 redis6380

D:/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 redis6381

D:/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 redis6382

D:/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 redis6383

D:/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 redis6384

D:/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 redis6380

D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6381

D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6382

D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6383

D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6384

D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6385

执行结果：

在Windows系统下搭建Redis集群

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，

在Windows系统下搭建Redis集群

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

2）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)

D:/Redis-Cluster/Redis-x64-3.2.100/redis-trib.rb create --replicas 1 127.0.0.1:6380 127.0.0.1:6381 127.0.0.1:6382 127.0.0.1:6383 127.0.0.1:6384 127.0.0.1:6385

>>> Check slots coverage...

[OK] All 16384 slots covered.

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

1、create：创建集群

2、check：检查集群

3、info：查看集群信息

4、fix：修复集群

5、reshard：在线迁移slot

6、rebalance：平衡集群节点slot数量

7、add-node：将新节点加入集群

8、del-node：从集群中删除节点

9、set-timeout：设置集群节点间心跳连接的超时时间

10、call：在集群全部节点上执行命令

11、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。
