voldemort 集群环境搭建

伏地魔 下载 0.8 ：
官方的 quickstart ： 

服务器 : 1 - 47,2 - 62,0 - 207  ( 对等，无主从 )

voldemort 安装到 :
1,2,0 - /data/tools/voldemort-0.80.2/


测试 1 ： NWR : 311  ( NWR  是什么 ?
  N - the replication factor (how many copies of each key-value pair we store)
  R - the number of reads required
  W- the number of writes we block fo
)
测试 1 -> 测试结果 :
  1. 正常启动
1,0,2 > /bin/bash /data/tools/voldemort-0.80.2/bin/voldemort-server.sh /data/tools/voldemort-0.80.2/config/test_config1
  # 路由 取值(成功)

1,0,2 > /bin/bash /data/tools/voldemort-0.80.2/bin/voldemort-shell.sh test tcp://localhost:6666
   2. 1 > put "m2test" "liukaiyi"

     # version(服务器ID:数据在此服务器版本号)
     . 0> get "m2test"
            version(1:1): "liukaiyi"
     . 2 > get "m2test"
            version(1:1): "liukaiyi"
  # 强行关闭 47 - 1 服务器
  # N3 （0，2）其他服务器能取到备份值 ， （非1）非原始存储 支持修改能成功。
  # 但 1 服务器从新开启 ， 原来在非原始存储修改数据，不在 使用 在 nrw 311 下
  3. 1 server > 关闭
       . 重新连接 0 > get "m2test" #能取到值 同步 成功
       . 重新连接 2 > get "m2test" #能取到值 同步 成功
       #在 0 中写入
      . 0 > put "m2test" "lky"
      . 2 > get "m2test"
            version(1:1,2:1): "liukaiyi"
      #注意 这里 重新 开启 1 服务器 ：
      0,1,2 > get "m2test"  #  version(1:1): "liukaiyi"

   # 修改  NWR 322
   0 > put "t1" "1"
         version(1:1): "liukaiyi"
   1 >  关闭 服务器 1
   2 > put "t1" "2"
         version(1:1,2:1): "lky"
   0 >  get "t1"
         version(1:1,2:1): "lky"
   1 > 服务器开启 get "t1" 
         version(1:1,2:1): "lky"
