Docker安装Zookeeper集群

一、 安装Docker

（略）

二、 安装Docker Compose

（略）

三、 编写docker-compose.yml文件

3.1 新建配置文件

touch cluster.yml

vim cluster.yml

cluster.yml配置如下

version: '3.7'

services:
  zoo1:
    image: zookeeper:3.5.5
    restart: always
    hostname: zoo1
    container_name: zookeeper_1
    volumes:
      - /usr/local/use_data/zookeeper/cluster/zoo_1/data:/data
      - /usr/local/use_data/zookeeper/cluster/zoo_1/log:/datalog
    ports:
      - 2181:2181
    environment:
      ZOO_MY_ID: 1
      ZOO_SERVERS: server.1=0.0.0.0:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181

  zoo2:
    image: zookeeper:3.5.5
    restart: always
    hostname: zoo2
    container_name: zookeeper_2
    volumes:
      - /usr/local/use_data/zookeeper/cluster/zoo_2/data:/data
      - /usr/local/use_data/zookeeper/cluster/zoo_2/log:/datalog
    ports:
      - 2182:2181
    environment:
      ZOO_MY_ID: 2
      ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=0.0.0.0:2888:3888;2181 server.3=zoo3:2888:3888;2181

  zoo3:
    image: zookeeper:3.5.5
    restart: always
    hostname: zoo3
    container_name: zookeeper_3
    volumes:
      - /usr/local/use_data/zookeeper/cluster/zoo_3/data:/data
      - /usr/local/use_data/zookeeper/cluster/zoo_3/log:/datalog
    ports:
      - 2183:2181
    environment:
      ZOO_MY_ID: 3
      ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=0.0.0.0:2888:3888;2181

3.2 启动容器

$ docker-compose -f ./cluster.yml up -d

3.3 查看容器状态

$ docker-compose -f ./cluster.yml ps

3.4 查看容器日志

$ docker-compose -f ./cluster.yml logs zoo1

四、 使用图形化界面

4.1 下载ZooInspector工具

下载地址

4.2 运行jar

1. 打开.\ZooInspector\build
2. 打开cmd
3. 执行java -jar zookeeper-dev-ZooInspector.jar

4.3 连接到zookeeper

4.4 新增节点
