Zookeeper 注册中心安装

本文演示windows10环境zookeeper伪集群模式安装，linux安装参考：https://dubbo.apache.org/zh/docs/v2.7/admin/install/zookeeper/

1、zookeeper下载地址：

http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.6.2/apache-zookeeper-3.6.2-bin.tar.gz

2、下载之后解压，复制三份

D:softzookeeper-clusterapache-zookeeper-3.6.2-12181

D:softzookeeper-clusterapache-zookeeper-3.6.2-12182

D:softzookeeper-clusterapache-zookeeper-3.6.2-12183

3、拷贝D:softzookeeper-clusterapache-zookeeper-3.6.2-12181confzoo_sample.cfg到当前目录，命名为拷贝D:softzookeeper-clusterapache-zookeeper-3.6.2-12181confzoo.cfg

修改zoo.cfg配置，节点1配置

tickTime=2000
initLimit=5
syncLimit=2
dataDir=D:\soft\zookeeper-cluster\apache-zookeeper-3.6.2-12181\data
dataLogDir=D:\soft\zookeeper-cluster\apache-zookeeper-3.6.2-12181\logs
clientPort=2181

server.1=127.0.0.1:2182:3800
server.2=127.0.0.1:2183:3801
server.3=127.0.0.1:2184:3802

节点2配置

tickTime=2000
initLimit=5
syncLimit=2
dataDir=D:\soft\zookeeper-cluster\apache-zookeeper-3.6.2-12182\data
dataLogDir=D:\soft\zookeeper-cluster\apache-zookeeper-3.6.2-12182\logs
clientPort=2182

server.1=127.0.0.1:2182:3800
server.2=127.0.0.1:2183:3801
server.3=127.0.0.1:2184:3802

节点3配置

tickTime=2000
initLimit=5
syncLimit=2
dataDir=D:\soft\zookeeper-cluster\apache-zookeeper-3.6.2-12183\data
dataLogDir=D:\soft\zookeeper-cluster\apache-zookeeper-3.6.2-12183\logs
clientPort=2183

server.1=127.0.0.1:2182:3800
server.2=127.0.0.1:2183:3801
server.3=127.0.0.1:2184:3802

4、创建myid文件

在D:softzookeeper-clusterapache-zookeeper-3.6.2-12181data目录下创建myid文件，文件内容1

在D:softzookeeper-clusterapache-zookeeper-3.6.2-12182data目录下创建myid文件，文件内容2

在D:softzookeeper-clusterapache-zookeeper-3.6.2-12183data目录下创建myid文件，文件内容3

以节点1为例，如下图：

5、启动zookeeper集群

依次启动三个节点

D:softzookeeper-clusterapache-zookeeper-3.6.2-12181inzkServer.sh start;

D:softzookeeper-clusterapache-zookeeper-3.6.2-12182inzkServer.sh start;

D:softzookeeper-clusterapache-zookeeper-3.6.2-12183inzkServer.sh start;

6、验证

telnet localhost 2181

telnet localhost 2182

telnet localhost 2183

7、zkui安装

下载地址：git clone https://github.com/DeemOpen/zkui.git

8、zkui编译

mvn clean install

9、zkui启动

编译后，将zkui-2.0-SNAPSHOT-jar-with-dependencies.jar和config.cfg文件拷贝到D:softzookeeper-clusterzkui目录

执行启动命令：java -jar zkui-2.0-SNAPSHOT-jar-with-dependencies.jar

10、ziui预览

打开浏览器，输入：http://localhost:9090/login，默认用户名密码：admin/manager，账号配置在config.cfg文件下。

登录后
