dubbo + zookeeper 环境搭建

一、zookeeper windows部署

1、下载安装

到官网下载解压版后解压至F:\server\zookeeper-3.4.8，剩下为文件配置工作；

2、本地伪集群

1) 在F:\server\zookeeper-3.4.8\conf 创建 zoo1.cfg，内容如下：

# The number of milliseconds of each tick  心跳间隔 毫秒每次

tickTime=2000

# The number of ticks that the initial

# synchronization phase can take

initLimit=10

# The number of ticks that can pass between

# sending a request and getting anacknowledgement

syncLimit=5

# the directory where the snapshot isstored.  //镜像数据位置

dataDir=F:\\server\\zookeeper-3.4.8\\data\\1

#日志位置

dataLogDir=F:\\server\\zookeeper-3.4.8\\log\\1

# the port at which the clients willconnect  客户端连接的端口

clientPort=2181

# server.id=host:port:port 
#  在服务器的 data (dataDir 参数所指定的目录)目录下创建一个文件名为 myid 的文件，
#  这个文件中仅含有一行的内容，指定的是自身的 id 值。
#  比如，服务器"1"应该在 myid 文件中写入"1"。这个 id 值必须是 ensemble 中唯一的，且大小在 1 到 255 之间。
#  这一行配置中，第一个端口（ port ）是从（ follower ）机器连接到主（ leader ）机器的端口，
#  第二个端口是用来进行 leader 选举的端口。
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889

2) 创建目录：F:\server\zookeeper-3.4.8\data\1 ，并在该目录下创建"myid"文件，内容为"1"；
3) 创建目录：F:\server\zookeeper-3.4.8\log\1 ；

4) 创建文件 F:\server\zookeeper-3.4.8\bin\zkServer-1.cmd  ，内容如下：

@echo off

setlocal
call "%~dp0zkEnv.cmd"

set ZOOMAIN=org.apache.zookeeper.server.quorum.QuorumPeerMain
set ZOOCFG=..\conf\zoo1.cfg
echo on
call %JAVA% "-Dzookeeper.log.dir=%ZOO_LOG_DIR%" "-Dzookeeper.root.logger=%ZOO_LOG4J_PROP%" -cp "%CLASSPATH%" %ZOOMAIN% "%ZOOCFG%" %*

endlocal

5) 重复上述步骤依次创建 zoo2.cfg， zoo3.cfg 及相应的目录、文件；

6) 依次运行 zkServer-1.cmd 、 zkServer-2.cmd 、zkServer-3.cmd 即可，前面启动的端口报错问题可以忽略，全部启动完毕后自动恢复正常。
