在Windows环境下搭建Redis集群

安装Redis

下载Windows版本Redis

下载地址: https://github.com/MicrosoftArchive/redis/releases

我下载了当前最新版本：Redis-x64-3.0.504.zip

下载后，将文件解压到D:\Program_Files\redis\redis-cluster目录（目录可以自定义，路径上不要有空格）

创建Redis集群节点

Redis集群至少需要6个节点，3主3从。主节点崩溃，从节点可以替补。

配置节点

将redis.windows.conf文件拷贝6份（也可以拷贝redis.windows-server.conf），修改以下配置：

port 6380
cluster-enabled yes
cluster-config-file nodes-6380.conf
cluster-node-timeout 15000
appendonly yes
cluster-enabled yes
appendfilename "appendonly.6380.aof"
cluster-slave-validity-factor 10
cluster-migration-barrier 1
cluster-require-full-coverage yes

将节点安装成服务

执行以下命令：

redis-server --service-install conf/redis.windows.6380.conf --service-name redis6380 --loglevel verbose
redis-server --service-install conf/redis.windows.6381.conf --service-name redis6381 --loglevel verbose
redis-server --service-install conf/redis.windows.6382.conf --service-name redis6382 --loglevel verbose
redis-server --service-install conf/redis.windows.6383.conf --service-name redis6383 --loglevel verbose
redis-server --service-install conf/redis.windows.6384.conf --service-name redis6384 --loglevel verbose
redis-server --service-install conf/redis.windows.6385.conf --service-name redis6385 --loglevel verbose

服务停启命令：

redis-server --service-start --service-name redis6379
redis-server --service-stop --service-name redis6379

已完成服务注册：

安装Ruby环境

下载Ruby

下载地址：https://rubyinstaller.org/downloads/

双击文件，安装向导安装。

下载Ruby环境下Redis驱动

执行命令安装

gem install redis

手动下载后安装

下载链接：https://rubygems.org/gems/redis/versions

下载后执行以下命令

gem install --local path\to\redis-5.0.6.gem

两种方式，任选一种。

创建集群环境

下载redis-trib.rb脚本

下载地址：https://github.com/beebol/redis-trib.rb

将redis-trib.rb文件拷贝到redis目录。

在redis目录下执行命令：

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

--replicas 1表示每个master有一个slave节点。

创建集群前，不能设置redis密码

设置redis密码

停止全部redis节点，修改全部配置文件

requirepass 12345678
masterauth  12345678

完成后启动全部节点。
