-------------環境安裝------------
#安裝redis


wget http://download.redis.io/releases/redis-3.2.5.tar.gz
tar xzf redis-3.2.5.tar.gz
cd redis-3.2.5
make


在src目錄存在src/redis-trib.rb   不需要執行gem install redis
#安裝ruby


./configure --prefix=/home/tianchao/ruby/
make
make test 可以檢測下編譯情況
make install






--------------redis cluster 配置和初始化-------------------------
######搭建3個master 3個slave
#cluster 配置檔案內容
#redis.conf檔案簡單配置
port 7000  #node埠
cluster-enabled yes  #
cluster-config-file nodes.conf  #node配置檔案 由redis-server自動生成 可以在在配置檔案中定義各個node的槽點SLOTS   總共有16384個槽點(0-16383)
cluster-node-timeout 5000
appendonly yes


#自動生成的nodes.conf

redis-trib.rb會自動分配16384個槽點
或者需要手動分配
