ZooKeeper Windows 集群搭建

ZooKeeper Windows 集群搭建

1 下载

ZooKeeper 下载地址：https://zookeeper.apache.org/releases.html#download

选择 Apache ZooKeeper 3.5.8(asc, sha512) 下载，解压文件到某一目录（目录不要带中文），本次测试解压后的目录是 apache-zookeeper-3.5.8。

2 修改配置文件 zoo.cfg

打开 apache-zookeeper-3.5.8 目录下的 conf 目录，复制 zoo_sample.cfg 文件并重命名为 zoo.cfg，使用 Notepad++ （或其他工具）打开文件 zoo.cfg，修改 dataDir 位置为：

dataDir=C:\\Software\\apache-zookeeper-3.5.8\\data

上面的 data 是数据存储的文件夹，需要自己新建（位置自己决定）。

3 集群搭建

集群搭建需要多个 ZooKeeper，本次使用：

  • 1 个 Leader
  • 2 个 Follower
  • 1 个 Observer

一共 4 个 ZooKeeper。

复制 3 次 apache-zookeeper-3.5.8 目录并重命名为 apache-zookeeper-3.5.8-2、apache-zookeeper-3.5.8-3、apache-zookeeper-3.5.8-4，名字自己决定。

集群的搭建配置有三点需要修改：

  1. 配置文件修改 clientPort
  2. 配置文件添加集群配置
  3. data 文件夹下添加 myid 文件

3.1 配置文件修改 clientPort

依次打开各个 ZooKeeper 的配置文件 zoo.cfg，修改 clientPort，每个端口号都不能重复，可以设置为 2181、2182 、2183、2184。

3.2 配置文件添加集群配置

每个 ZooKeeper 的配置文件下添加如下配置（端口号自己决定）：

server.1=127.0.0.1:2881:3881
server.2=127.0.0.1:2882:3882
server.3=127.0.0.1:2883:3883
server.4=127.0.0.1:2884:3884:observer

3.3 data 文件夹下添加 myid 文件

在每个 ZooKeeper 的 data 目录下新建 myid，注意文件名就叫 myid，没有任何后缀，内容依次为 1、2、3、4。

3.4 全部配置展示

    .\conf 下的 zoo.cfg：

    # The number of milliseconds of each tick

# sending a request and getting an acknowledgement
syncLimit=5

# example sakes.
dataDir=C:\\Software\\apache-zookeeper-3.5.8\\data

4 脚本

集群实例如果依次启动比较麻烦，可以创建脚本快速启动，新建文件 zookeeperstart.bat，文件内容如下：

@echo off
title zookeeper集群启动

cd /d C:\Software\apache-zookeeper-3.5.8\bin
start zkServer.cmd
echo zookeeper集群节点1启动

cd /d C:\Software\apache-zookeeper-3.5.8-2\bin
start zkServer.cmd
echo zookeeper集群节点2启动

cd /d C:\Software\apache-zookeeper-3.5.8-3\bin
start zkServer.cmd
echo zookeeper集群节点3启动

cd /d C:\Software\apache-zookeeper-3.5.8-4\bin
start zkServer.cmd
echo zookeeper集群节点4启动
