redis集群中至少應該有三個節點。要保證集群的高可用，需要每個節點有乙個備份機。
redis集群至少需要6臺伺服器。
搭建偽分布式。可以使用一台虛擬機器執行6個redis例項。需要修改redis的埠號7001-7006
集群搭建環境
1、使用ruby指令碼搭建集群。需要ruby的執行環境。
安裝ruby
yum install ruby
yum install rubygems
安裝ruby指令碼執行使用的包。
[root@localhost ~]# gem install redis-3.0.0.gem
successfully installed redis-3.0.0
1 gem installed
installing ri documentation for redis-3.0.0...
installing rdoc documentation for redis-3.0.0...
[root@localhost ~]#
[root@localhost ~]# cd redis-3.0.0/src
[root@localhost src]# ll *.rb
-rwxrwxr-x. 1 root root 48141 apr 1 2015 redis-trib.rb
需要6臺redis伺服器。搭建偽分布式。
需要6個redis例項。
需要執行在不同的埠7001-7006
第一步：建立6個redis例項，每個例項執行在不同的埠。需要修改redis.conf配置檔案。配置檔案中還需要把cluster-enabled yes前的注釋去掉。
第二步：啟動每個redis例項。
第三步：使用ruby指令碼搭建集群。
