Redis八：Windows环境下的Redis集群搭建

• 数据库


一、准备工作

本次Redis 集群搭建使用官方提供的Redis Cluster的管理工具：redis-trib.rb；

一共需要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。

Redis八：Windows环境下的Redis集群搭建

下载

  1. 下载Redis安装文件：https://github.com/microsoftarchive/redis/releases/tag/win-3.2.100 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 无法下载的话这理由阿里云盘地址：「rubyinstaller-2.7.5-1-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（点击页面右下角“相关链接”里的“下载”）Redis八：Windows环境下的Redis集群搭建
  4. 下载Redis官方提供的创建Redis集群的ruby脚本文件redis-trib.rb https://raw.githubusercontent.com/MSOpenTech/redis/3.0/src/redis-trib.rb 如法下载的话这理有阿里云盘下载地址：https://www.aliyundrive.com/s/bGgYqmZ3hYn

二、安装Redis

将下载的 Redis-x64-3.2.100.zip 解压到 D盘下的 Redis-Cluster 文件夹里：D:/Redis-Cluster/Redis-x64-3.2.100

配置 Redis 实例

需要运行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，将创建一个三主三从的集群；

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。

安装Redis服务

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

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

服务卸载命令

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Redis服务

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

Redis八：Windows环境下的Redis集群搭建

三、安装Ruby

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 D:/Ruby27-x64

Redis八：Windows环境下的Redis集群搭建

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

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（D:/Ruby27-x64）下。

然后执行安装命令如下：

gem install --local D:/Ruby27-x64/redis-3.2.2.gem

四、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。

使用redis-trib.rb来创建Redis集群

CMD 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 for open slots...
>>> 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

检验是否创建成功

输入一下命令

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。
