准备工作：
首先必须安装redis，安装完后，安装例如以下内容：
</pre><pre name="code" class="html"> sudo yum install ruby sudo yum install rubygem yum install -y ruby-devel ruby-docs ruby-ri ruby-rdoc yum install -y rubygems gem install redis
创建集群须要的文件夹
mkdir -p /usr.local/cluster cd /usr.local/cluster mkdir 7000 mkdir 7001 mkdir 7002 mkdir 7003 mkdir 7004 mkdir 7005
cp /home/sq/redis.conf /usr.local/cluster改动配置文件redis.conf
vi redis.conf ##改动配置文件里的以下选项 port 7000 daemonize yes cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 appendonly yes ##改动完redis.conf配置文件里的这些配置项之后把这个配置文件分别复制到7000/7001/7002/7003/7004/7005文件夹以下 cp /usr/local/cluster/redis.conf /usr/local/cluster/7000 cp /usr/local/cluster/redis.conf /usr/local/cluster/7001 cp /usr/local/cluster/redis.conf /usr/local/cluster/7002 cp /usr/local/cluster/redis.conf /usr/local/cluster/7003 cp /usr/local/cluster/redis.conf /usr/local/cluster/7004 cp /usr/local/cluster/redis.conf /usr/local/cluster/7005 ##注意：拷贝完毕之后要改动7001/7002/7003/7004/7005文件夹以下redis.conf文件里的port參数，分别改为相应的文件夹的名称
cd /usr/local/cluster/7000分别启动这6个redis实例
redis-server redis.conf cd /usr/local/cluster/7001 redis-server redis.conf cd /usr/local/cluster/7002 redis-server redis.conf cd /usr/local/cluster/7003 redis-server redis.conf cd /usr/local/cluster/7004 redis-server redis.conf cd /usr/local/cluster/7005 redis-server redis.conf
创建集群
./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
报错，例如以下所看到的
Connecting to node 127.0.0.1:7001: [ERR] Sorry, can't connect to node 127.0.0.1:7001
下载最新的配置文件。反复上面集群命令。成功。
