 		 分类： redis
准备了3台机器，每台机器上面起7000 和7001端口
http://download.redis.io/releases/redis-3.0.2.tar.gz
解压后到包里面
make
make install 安装就好了
创建集群需要的目录
 mkdir /usr/local/redis/7000 -p
mkdir /usr/local/redis/7001 -p
修改配置文件 redis.conf
cd /usr/local/redis/7000/
    vim redis.conf
port 7000
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
## 修改完 redis.conf 配置文件中的这些配置项之后把这个配置文件分别拷贝到7001 和另外2台机器上
## 注意：拷贝完成之后端口要修改7001
分别启动这 6 个 redis 实例
这样每台机器上面启动2个实例
/usr/local/redis/7000/redis-server /usr/local/redis/7000/redis.conf 
/usr/local/redis/7001/redis-server /usr/local/redis/7001/redis.conf 

##启动之后使用命令查看redis的启动情况ps -ef|grep redis

6：执行redis的创建集群命令创建集群

        from /root/redis-3.0.2/src/redis-trib.rb:24


报错了，提示缺少rubygems组件，使用yum安装

yum -y install rubygems

安装好后还是报错

/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'

提示不能加载redis，是因为缺少redis和ruby的接口，使用gem 安装

# gem install redis

居然只连接5个，奇怪了，后来检查才发现在--replicas 后面要加一个数字才可以

在这里的时候卡了很久没过去，我就结束了想重新再试下

Connecting to node 192.168.7.232:7000: OK

[ERR] Node 192.168.7.232:7000 is not empty. Either the node already knows other nodes (check with CLUSTER NODES) or contains some key in database 0.

提示有数据了，我想是开始初始化的时候有写数据进去了

把7000目录下生成的appendonly.aof    nodes.conf 删除掉重启启动服务，

想起来我是把7.232上面的服务启动后把7000 7001 直接传到237 和246上面去的，为了节省建目录和copy配置文件的操作，这样导致机器加入集群的时候一直在等待，

把3台机器的6个服务的appendonly.aof    nodes.conf都删了 重新启动服务再执行

使用redis-cli命令进入集群环境

redis-cli -c -p 7000
