Redis3.0集群安装手册鲁强概述要让集群正常工作至少需要3个主节点，在这里我们要创建6个redis节点，其中三个为主节点，三个为从节点，对应的redis节点的ip和端口对应关系如下127.0.0.1:7000127.0.0.1:7001127.0.0.1:7002127.0.0.1:7003127.0.0.1:7004127.0.0.1:7005准备环境安装ruby集群环境需要ruby，所以需要安装下yum install ruby?yum install ruby-rdocruby setup.rb安装完毕后启动依然报错需要安装redis库gem install redis问题解决下载必威体育精装版redis版本3.06 并进行构建创建用户useradd redispasswd redis切换用户su – redis上传redis包到home目录tar?-zxvf?redis-3.0.6.tar.gz?mv?redis-3.0.6?redis3.0cd?redis3.0make本环境为伪集群环境，所以在一台机器，多机情况相同mkdir? /home/redis/ cluster-testcd?/home/redis/ cluster-testmkdir?7000mkdir?7001mkdir?7002mkdir?7003mkdir?7004mkdir?7005修改配置将配置文件CP到各个集群节点目录下并修改端口号将redis-server cp到各个集群几点目录下详见配置文件范例启动环境运行startAll.sh文件即可启动集群Client 连接集群任意一个节点即可添加新主节点使用命令./redis-trib.rb add-node 10.4.89.16:7006 10.4.89.16:7000第一个为新节点IP端口第二个参数为任意节点IP添加后日志信息 Adding node 10.4.89.16:7006 to cluster 10.4.89.16:7000 Performing Cluster Check (using node 10.4.89.16:7000)M: 7e81d801c3ce503868c67dd6b47b82b8e04458ce 10.4.89.16:7000 slots:0-5460 (5461 slots) master 1 additional replica(s)M: c744b599c7cf31c05ed5a95f831461de8d5dfb95 10.4.89.16:7002 slots:10923-16383 (5461 slots) master 1 additional replica(s)M: d5297c5cee8a142123775224f39cce499fd7c435 10.4.89.16:7001 slots:5461-10922 (5462 slots) master 1 additional replica(s)S: d2c5ca33820cda4f8f1e98fbfcd72cf91bc7b676 10.4.89.16:7004 slots: (0 slots) slave replicates d5297c5cee8a142123775224f39cce499fd7c435S: b501af87c221ba53f7edd76bf1b5a77352d963be 10.4.89.16:7003 slots: (0 slots) slave replicates 7e81d801c3ce503868c67dd6b47b82b8e04458ceS: 77472bc34b72345b939b585157f4fc70fea81327 10.4.89.16:7005 slots: (0 slots) slave replicates c744b599c7cf31c05ed5a95f831461de8d5dfb95[OK] All nodes agree about slots configuration.

Send CLUSTER MEET to node 10.4.89.16:7006 to make it join the cluster.脚本先检查了集群状态，后添加了节点，添加后节点是空节点./redis-cli -c -p 7000 cluster nodes查看后发现2e9bdb7ea488a3d5ee5b92f32d65a176bf7b41bd 10.4.89.16:7006
