voldemort 集群环境搭建

时间：2010-05-28 来源：liukaiyi

伏地魔下载 0.8 ： http://github.com/voldemort/voldemort/downloads
官方的 quickstart ： http://project-voldemort.com/quickstart.php

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)
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"
