【zookeeper】

window下安装zookeeper三结点集群：

1：解压缩zookeeper压缩包：复制三分并且命名成：Server_A   Server_B  Server_C

2：拷贝conf目录下的文件zoo_sample.cfg 并重命名为zoo.cfg

3：编辑zoo.cfg

为了降低更新的延迟，需要为事物日志的存放专门指定存储路径，该配置项为：dataLogDir

# zA.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=C:/javaSoft/zookeeper/data/Server_A/data
dataLogDir=C:/javaSoft/zookeeper/data/Server_A/log
clientPort=2181
server.1=127.0.0.1:2881:3881
server.2=127.0.0.1:2882:3882
server.3=127.0.0.1:2883:3883

# zoo2.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir=C:/javaSoft/zookeeper/data/Server_B/data
dataLogDir=C:/javaSoft/zookeeper/data/Server_B/log
clientPort=2182

server.1=127.0.0.1:2881:3881
server.2=127.0.0.1:2882:3882
server.3=127.0.0.1:2883:3883

# zoo3.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir=C:/javaSoft/zookeeper/data/Server_C/data
dataLogDir=C:/javaSoft/zookeeper/data/Server_C/log
clientPort=2183

server.1=127.0.0.1:2881:3881
server.2=127.0.0.1:2882:3882
server.3=127.0.0.1:2883:3883

 4:需要在配置项dataDir所指示目录下创建文件myid文件，其内容为该1中server.x中的x，表示该zookeeper服务器的编号

5：同理配置三台zookeeper。一次启动即可：

C:\javaSoft\zookeeper\Server_A\bin\zkServer.cmd

C:\javaSoft\zookeeper\Server_B\bin\zkServer.cmd

C:\javaSoft\zookeeper\Server_C\bin\zkServer.cmd
