在安装redis集群之前，要先安装一些环境
(1)安装zlib
确保系统安装zlib,否则gem install会报(no such file to load -- zlib)
zlib-1.2.6.tar
./configure
make
make install
(2)安装ruby
ruby 使用本地yum安装也能使用(推荐)
编译安装：
这里不能使用make & make install
ruby1.9.2
./configure -prefix=/usr/local/ruby
make
make install
sudo cp ruby /usr/local/bin
(3)安装rubygem:version(1.8.16)
# rubygems-1.8.24.tgz
cd /path/gem
sudo ruby setup.rb
(4)安装gem-redis:version(3.0.0)
将网络放开，切换为淘宝源地址：
# gem source -l
# gem source --remove http://rubygems.org/
# gem sources -a https://ruby.taobao.org/
# gem source -l
gem install redis --version 3.0.0
报错信息：
ERROR: RDoc documentation generator not installed: no such file to load -- rdoc/rdoc
解决办法：
yum install ruby-rdoc -y
vi redis.conf
##修改配置文件中的下面选项
port 7000
daemonize yes
cluster-enabled yes
cluster-config-file nodes-对应端口号.conf
cluster-node-timeout 5000
appendonly yes
bind ip地址
以配置文件分别启动这6个redis实例
redis-server redis.conf指定以配置文件启动
--replicas 1代表一个主节点下面有一个副节点
