这里创建6个redis节点，其中三个为主节点，三个为从节点。
redis和端口对应关系：
127.0.0.1:7000
127.0.0.1:7001
127.0.0.1:7002
从：
127.0.0.1:7003127.0.0.1:7004127.0.0.1:7005步骤：1,下载redis。官网下载3.0.0版本，之前几的版本不支持集群模式
下载地址：
2：上传服务器，解压，编译tar -zxvf redis-3.0.0-rc2.tar.gzmv redis-3.0.0-rc2.tar.gz redis3.0cd /usr/local/redis3.0make & make install3：创建集群需要的目录并拷贝redismkdir -p /usr/local/clustermkdir -p /usr/local/cluster/7000mkdir -p /usr/local/cluster/7001mkdir -p /usr/local/cluster/7002mkdir -p /usr/local/cluster/7003mkdir -p /usr/local/cluster/7004mkdir -p /usr/local/cluster/7005cp -rf /usr/local/redis3.0/* /usr/local/cluster/7000/cp -rf /usr/local/redis3.0/* /usr/local/cluster/7001/cp -rf /usr/local/redis3.0/* /usr/local/cluster/7002/cp -rf /usr/local/redis3.0/* /usr/local/cluster/7003/cp -rf /usr/local/redis3.0/* /usr/local/cluster/7004/cp -rf /usr/local/redis3.0/* /usr/local/cluster/7005/4：修改配置文件redis.confvi /usr/local/cluster/7000/redis.conf##修改配置文件中的下面选项port 7000daemonize yescluster-enabled yescluster-config-file nodes.confcluster-node-timeout 5000appendonly yes#同样再对其它配置文件进行修改vi /usr/local/cluster/7001/redis.confvi /usr/local/cluster/7002/redis.confvi /usr/local/cluster/7003/redis.confvi /usr/local/cluster/7004/redis.confvi /usr/local/cluster/7005/redis.conf##注意：不同的目录配置不同的redis.conf中的port5：启动6个rediscd /usr/local/cluster/7000/srcredis-server ../redis.confcd /usr/local/cluster/7001/srcredis-server ../redis.confcd /usr/local/cluster/7002/srcredis-server ../redis.confcd /usr/local/cluster/7003/srcredis-server ../redis.confcd /usr/local/cluster/7004/srcredis-server ../redis.confcd /usr/local/cluster/7005/srcredis-server ../redis.conf##启动之后使用命令查看redis的启动情况ps -ef|grep redis6,创建redis集群cd /usr/local/redis3.0/src./redis-trib.rb create –replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:70056.1执行上面的命令的时候会报错，因为是执行的的脚本，需要错误内容：/usr/bin/env: ruby: No such file or directory所以需要安装ruby的环境，这里推荐使用yum install rubyyum install ruby6.2然后再执行第步的创建集群命令，还会报错，提示缺少rubygems组件错误内容：./redis-trib.rb:24:in `require’: no such file to load — rubygems (LoadError)from ./redis-trib.rb:24yum install rubygems6.3再次执行第步的命令，还会报错，提示不能加载redis，是因为缺少redis的接口错误内容：/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require’: no such file to load — redis (LoadError)from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require’from ./redis-trib.rb:25gem install redis这里可能无法安装,因为无法连接gem服务器：[@zw_22_90 src]# gem install redis –version 3.0.0 ERROR: Could not find a valid gem ‘redis’ (= 3.0.0) in any repositoryERROR: While executing gem … (Gem::RemoteFetcher::FetchError)需要手工下载并安装：wget https://rubygems.global.ssl.fastly.net/gems/redis-3.2.1.gemgem install -l ./redis-3.2.1.gem6.4 再次执行第步的命令，正常执行输入yes，然后配置完成。[@zw_22_90 src]# ./redis-trib.rb create –replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005>>> Creating clusterConnecting to node 127.0.0.1:7000: OKConnecting to node 127.0.0.1:7001: OKConnecting to node 127.0.0.1:7002: OKConnecting to node 127.0.0.1:7003: OKConnecting to node 127.0.0.1:7004: OKConnecting to node 127.0.0.1:7005: OK>>> Performing hash slots allocation on 6 nodes…Using 3 masters:127.0.0.1:7000127.0.0.1:7001127.0.0.1:7002Adding replica 127.0.0.1:7003 to 127.0.0.1:7000Adding replica 127.0.0.1:7004 to 127.0.0.1:7001Adding replica 127.0.0.1:7005 to 127.0.0.1:7002M: 2022f24d581b4a7c3342e3245c32927cbd5ec16d 127.0.0.1:7000 slots:0-5460 (5461 slots) masterM: 37b7008f80f8c21a698da8cb1f1b32db8c0c415c 127.0.0.1:7001 slots:5461-10922 (5462 slots) masterM: ac6dc5fa96e856b34c1ba4c3814394e4ebb698dd 127.0.0.1:7002 slots:10923-16383 (5461 slots) masterS: b5b76d70bbb0dbf3e7df8a38f1259e95e2054721 127.0.0.1:7003 replicates 2022f24d581b4a7c3342e3245c32927cbd5ec16dS: 6881f8fef9c25da486f320ebf2ead39c1502db4c 127.0.0.1:7004 replicates 37b7008f80f8c21a698da8cb1f1b32db8c0c415cS: f090526d32cced97731eef2a2e1722a7bac7d9ea 127.0.0.1:7005 replicates ac6dc5fa96e856b34c1ba4c3814394e4ebb698ddCan I set the above configuration?
