版本信息：
ubuntu 16.04
gcc version 5.4.0
版本问题真的很重要，很有可能在别人的电脑里面可以正常操作，换一台就…呵呵，你懂得！
好，废话不多说，来代码！！
1.安装redis:
1）下载解压：
/usr/local$ sudo wget http://download.redis.io/releases/redis-3.0.2.tar.gz
/usr/local$ sudo tar -xvzf redis-3.0.2.tar.gz
/usr/local$ cd redis-3.0.2/
2)编译安装(/usr/local/redis-3.0.2/)
sudo make
sudo make install
提示编译成功：
Hint: It's a good idea to run 'make test' ;)
make[1]: Leaving directory '/usr/local/redis-3.0.2/src'
2.配置文件修改：
1）创建文件夹：
/usr/local$ sudo mkdir redis-service
2）在reddis-service下创建6个文件夹：
sudo mkdir redis-7000 redis-7001 redis-7002 redis-7003 redis-7004 redis-7005
注：要让集群正常工作至少需要3个主节点,在这里我们要创建6个redis节点, 其中三个为主节点(master),三个为从节点(slave),对应的redis节点的ip和端口对应关系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
3）复制redis3.0.2下的redis.conf 到上一级目录的redis-service
4）修改文件名：
sudo mv redis.conf redis-cluster.conf
dss@dss:/usr/local/redis-service$ ls
redis-7000 redis-7002 redis-7004 redis-cluster.conf
redis-7001 redis-7003 redis-7005
5）复制redis-cluster.conf 分别到这六个文件夹内：
6）分别修改每个文件夹内的配置文件：
修改命令：
/usr/local/redis-service/redis-7000$ sudo vim redis-cluster.conf
修改内容例如：redis-7000:
port 7000
daemonize yes
pidfile redis-7000.pid
cluster-enabled yes
cluster-config-file nodes-7000.conf
cluster-node-timeout 15000 #看情况而定,尽量保持每台机子的原数据
appendonly yes
7）复制 redis-server 到/usr/local/redis-service/：
/usr/local/redis-3.0.2/src$ sudo cp redis-server /usr/local/redis-service/
8）执行redis：
/usr/local/redis-service$ sudo ./redis-server redis-7000/redis-cluster.conf &
/usr/local/redis-service$ sudo ./redis-server redis-7001/redis-cluster.conf &
/usr/local/redis-service$ sudo ./redis-server redis-7002/redis-cluster.conf &
/usr/local/redis-service$ sudo ./redis-server redis-7003/redis-cluster.conf &
/usr/local/redis-service$ sudo ./redis-server redis-7004/redis-cluster.conf &
/usr/local/redis-service$ sudo ./redis-server redis-7005/redis-cluster.conf &
注：&符号是为了在执行时不占用本窗口！如果不加，你可以试试（手动滑稽
这样就成功启动了redis
3.安装集群工具：
1）安装ruby及交互环境：
/usr/local$ sudo apt-get install ruby
/usr/local$ sudo apt-get install irb
/usr/local$ sudo apt-get install ri
2）安装rubygems(必须安装,否则无法启动集群命令)
RubyGems 旨在方便地管理 gem 安装的工具,以及用于分发 gem 的服务器。这类似于Ubunt u 下的apt -get , Cent os 的 yum,Pyt hon 的 pip！！
sudo apt-get install rubygems
出现下面的情况的话：就只能手动编译安装了！
注意，选中 'ruby' 而非 'rubygems'
ruby 已经是最新版 (1:2.3.0+1)。
官网下载rubygems安装包:https://rubygems.org/pages/download
cd /usr/local/src
sudo mkdir rubygems
移动到/usr/local/scr/rubygems/路径下！
解压安装包：
sudo unzip rubygems-2.7.7.zip
cd rubygems-2.7.7
执行命令：
sudo ruby setup.rb
安装成功提示：
RubyGems installed the following executables:
/usr/bin/gem2.3
/usr/bin/bundle2.3
通过gem安装redis：
sudo gem install redis
Fetching: redis-4.0.1.gem (100%)
Successfully installed redis-4.0.1
Parsing documentation for redis-4.0.1
Installing ri documentation for redis-4.0.1
Done installing documentation for redis after 1 seconds
1 gem installed
安装成功！！
进入/usr/local/redis-3.0.2/src,查找redis-trib.rb，并复制到redis-service
/usr/local/redis-3.0.2/src$ sudo cp redis-trib.rb /usr/local/redis-service/
启动集群命令：
sudo ./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
