在Windows系统下搭建Redis集群

比眉伴天荒 2022-12-22 12:27 195阅读 0赞

## 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。

![1b31f1bd07d77cedbb8bddf5a755000a.png][]

1）下载Redis安装文件：[https://github.com/MSOpenTech/redis/releases/][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][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][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

![2b65e013155e33343082d76257546283.png][]

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][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、

redis.6381.conf、

redis.6382.conf、

redis.6383.conf、

redis.6384.conf、

redis.6385.conf

![8f900a89c6347c561fdf2122f13be562.png][]

**配置解释如下：**

![复制代码][48304ba5e6f9fe08f3fa1abda7d326ab.png]

1 port 6380                                 #端口号
     2 loglevel notice                           #日志的记录级别，notice是适合生产环境的
     3 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
     4 syslog-enabled yes                        #是否使用系统日志
     5 syslog-ident redis6380                    #在系统日志的标识名
     6 appendonly yes                            #数据的保存为aof格式
     7 appendfilename "appendonly.6380.aof"      #数据保存文件
     8 cluster-enabled yes                       #是否开启集群
     9 cluster-config-file nodes.6380.conf
    10 cluster-node-timeout 15000
    11 cluster-slave-validity-factor 10
    12 cluster-migration-barrier 1
    13 cluster-require-full-coverage yes

![复制代码][48304ba5e6f9fe08f3fa1abda7d326ab.png]

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：

![复制代码][48304ba5e6f9fe08f3fa1abda7d326ab.png]

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.6385.conf --service-name redis6385

![复制代码][48304ba5e6f9fe08f3fa1abda7d326ab.png]

**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：

![复制代码][48304ba5e6f9fe08f3fa1abda7d326ab.png]

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.6385.conf --service-name redis6385

![复制代码][48304ba5e6f9fe08f3fa1abda7d326ab.png]

启动这6个服务，命令如下：

![复制代码][48304ba5e6f9fe08f3fa1abda7d326ab.png]

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

![复制代码][48304ba5e6f9fe08f3fa1abda7d326ab.png]

执行结果：

![aefeb406361836ffa03f00867223d99e.png][]

## 安装ruby ##

1）Ruby环境安装。

双击下载的“[rubyinstaller-2.2.4-x64.exe][http_dl.bintray.com_oneclick_rubyinstaller_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，

![9f38ae9994a6c71f8b55fc7908716e2a.png][]

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

![dc57d0d19cb6e64ec975bec6209a4ba7.png][]

## 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

![复制代码][48304ba5e6f9fe08f3fa1abda7d326ab.png]

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

![复制代码][48304ba5e6f9fe08f3fa1abda7d326ab.png]

### 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。
