一、环境
ubuntu 14.04 LTS、 redis 3.0.2
二、redis cluster 搭建 （单机测试）
1、redis的安装
wget http://download.redis.io/releases/redis-3.0.2.tar.gz tar zxvf redis-3.0.2.tar.gz cd redis-3.0.2/ make make install
2、安装ruby
sudo apt-get install ruby sudo gem install redis #ruby的redis驱动
3、在单机测试的话，我们用redis-server分别启动多个文件就可以了，我这里采用的是6个端口，在redis cluster 里是三主、三从…. 当时也可以按照自己的情况设立主从…. 需要注意的是redis.conf要开发cluster的选项。 我简单写了一个批量修改redis.conf的脚本.
for i in `seq -w 0 5`;do
cp redis.conf 700$i.conf
sed -i "s/6379/700$i/g" 700$i.conf
sed -i ‘s/daemonize no/daemonize yes/g‘ 700$i.conf
sed -i ‘s/# cluster-enabled yes/cluster-enabled yes/g‘ 700$i.conf
sed -i ‘s/# cluster-node-timeout 15000/cluster-node-timeout 15000/g‘ 700$i.conf
sed -i "s/# cluster-config-file nodes-700*/cluster-config-file nodes-700$i.conf/g" 700$i.conf
redis-server 700$i.conf
done
4、检测进程
[email protected]:/etc/redis$ ps aux | grep redis root 8913 0.1 1.0 38508 10948 ? Ssl 10:27 0:02 redis-server *:7000 [cluster] root 8923 0.1 1.0 38508 10972 ? Ssl 10:27 0:02 redis-server *:7001 [cluster] root 8933 0.1 1.0 38508 11016 ? Ssl 10:27 0:02 redis-server *:7002 [cluster] root 8943 0.1 0.8 38508 8868 ? Ssl 10:27 0:02 redis-server *:7003 [cluster] root 8953 0.1 0.9 38508 9196 ? Ssl 10:27 0:02 redis-server *:7004 [cluster] root 8963 0.1 0.8 38508 8972 ? Ssl 10:27 0:02 redis-server *:7005 [cluster]
5、用redis-trib.rb来创建redis cluster集群，下面是成功的提示。

6、开启集群模式
[email protected]:/tmp/soft/redis-3.0.2/src# redis-cli -c -p 7001 -h 127.0.0.1
