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。
下载
- 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。
- 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」
- 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”)
- 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
- 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;
- 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 yes appendfilename "appendonly.6380.aof" cluster-enabled yes cluster-config-file nodes.6380.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6381.conf
port 6381 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6381_log.txt" appendonly yes appendfilename "appendonly.6381.aof" cluster-enabled yes cluster-config-file nodes.6381.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6382.conf
port 6382 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6382_log.txt" appendonly yes appendfilename "appendonly.6382.aof" cluster-enabled yes cluster-config-file nodes.6382.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6383.conf
port 6383 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6383_log.txt" appendonly yes appendfilename "appendonly.6383.aof" cluster-enabled yes cluster-config-file nodes.6383.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6384.conf
port 6384 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6384_log.txt" appendonly yes appendfilename "appendonly.6384.aof" cluster-enabled yes cluster-config-file nodes.6384.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6385.conf
port 6385 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6385_log.txt" appendonly yes appendfilename "appendonly.6385.aof" cluster-enabled yes cluster-config-file nodes.6385.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
配置相关解释
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.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
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
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
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

备注
- –replicas #指定集群中每个主节点配备几个从节点,这里设置为1。
- 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。
