1、安裝需要的依賴包
[[email protected] ~]# yum install gcc gcc-c++ kernel-devel automake autoconf libtool make wget tcl vim ruby rubygems unzip git -y  
2. 下載redis並安裝
[[email protected] src]# cd /usr/local/  
[[email protected] local]# wget http://download.redis.io/releases/redis-4.0.1.tar.gz  
[[email protected] local]# tar xzf redis-4.0.1.tar.gz  
[[email protected] local]# cd redis-4.0.1  
[[email protected] redis-4.0.1]# make  
3. 建立叢集需要的目錄
mkdir -p /usr/local/cluster  
cd /usr/local/cluster  
mkdir –p /usr/local/cluster/7000  
mkdir –p /usr/local/cluster/7001 
mkdir –p /usr/local/cluster/7002
mkdir –p /usr/local/cluster/7003
mkdir –p /usr/local/cluster/7004
mkdir –p /usr/local/cluster/7005
4. 修改配置檔案redis.conf
port 7000（7002,7003,7004,7005）  
daemonize yes  
cluster-enabled yes  
cluster-config-file nodes_700X.conf  
cluster-node-timeout 5000  
appendonly yes 
appendfilename "appendonly_700X.aof"
pidfile /var/run/redis_700X.pid
這個配置檔案分別拷貝到7000/7001/7002/7003/7004/7005節點目錄。
5.分別啟動這6個redis例項
/usr/local/redis-4.0.1/src/redis-server  ./7000/redis.conf
/usr/local/redis-4.0.1/src/redis-server  ./7001/redis.conf
/usr/local/redis-4.0.1/src/redis-server  ./7002/redis.conf
/usr/local/redis-4.0.1/src/redis-server  ./7003/redis.conf
/usr/local/redis-4.0.1/src/redis-server  ./7004/redis.conf
/usr/local/redis-4.0.1/src/redis-server  ./7005/redis.conf
並檢視是否成功：ps -ef|grep redis
6. 執行redis的建立叢集命令建立叢集
[[email protected] cluster]# cd /usr/local/redis-4.0.1/src  
[[email protected] src]# ./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  
到這一步因為前面第1步裝了依賴包，未提示ruby和rubygems的錯誤，但還是會報錯，提示不能載入redis，是因為缺少redis和ruby的介面，使用gem 安裝
錯誤內容：
/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'
        from ./redis-trib.rb:25
解決：gem install redis
還可能會提示ruby版本太低，需要安裝高版本。
wget https://cache.ruby-china.org/pub/ruby/ruby-2.3.1.tar.gz
tar xzvf ruby-2.3.1.tar.gz  
cd ruby-2.3.1  
./configure –prefix=/usr/local/ruby  
make && make install  
7.重新執行建立叢集的命令
。。。。。。。
[OK] All nodes agree about slots configuration.  
>>> Check for open slots...  
>>> Check slots coverage...  
[OK] All 16384 slots covered.  
8. 測試叢集
[[email protected] src]# ./redis-cli -c -p 7000
127.0.0.1:7000> set username xjs
-> Redirected to slot [14315] located at 127.0.0.1:7002
OK


[[email protected] ~]# /usr/local/redis-4.0.1/src/redis-cli -c -p 7005
127.0.0.1:7005> get username
-> Redirected to slot [14315] located at 127.0.0.1:7002
"xjs"
