运行 apache-zookeeper-3.7.0-bin/bin/zkServer.cmd

默认客户端端口 0.0.0.0/0.0.0.0:2181

Linux (CenterOS 7)

下载压缩包

wget https://dlcdn.apache.org/zookeeper/zookeeper-3.7.0/apache-zookeeper-3.7.0-bin.tar.gz

解压可以自己指定路径

tar -zxvf zookeeper-3.7.0.tar.gz
cd apache-zookeeper-3.7.0-bin/
ls
# bin  conf  docs  lib  LICENSE.txt  NOTICE.txt  README.md  README_packaging.md
cd conf
#复制配置
cp zoo_sample.cfg zoo.cfg

修改配置zoo.cfg

vim zoo.cfg

dataDir=/root/zookeeper-data

运行服务

./zkServer.sh start

停止服务

./zkServer.sh stop

集群配置

配置参数

参数	描述
tickTime =2000	通信心跳数，Zookeeper服务器与客户端心跳时间，单位毫秒
initLimit =10	LF初始通信时限
syncLimit =5	LF同步通信时限
dataDir	数据文件目录+数据持久化路径
clientPort =2181	客户端连接端口

复制三份ZooKeeper 模拟集群
各添加配置

server.1=localhost:2888:3888
server.2=localhost:2889:3889
server.3=localhost:2887:3887

修改客户端端口分别如下

clientPort=2181
clientPort=2182
clientPort=2183

配置完成分别启动，Window和Linux区别在于操作不同、Windows执行命令为.cmd,Linux 为.sh
