dokcer搭建zookeeper集群

**dockerhub 资料地址：[https://hub.docker.com/\_/zookeeper][https_hub.docker.com_zookeeper]**

**官方地址：[https://zookeeper.apache.org/doc/current/zookeeperStarted.html][https_zookeeper.apache.org_doc_current_zookeeperStarted.html]**

**1. 拉取镜像**

docker pull zookeeper

**2. 启动镜像(此镜像包括`EXPOSE 2181 2888 3888 8080`（zookeeper客户端端口，跟随端口，选择端口，AdminServer端口），因此标准容器链接将使其自动可用于链接的容器。由于Zookeeper“快速失败”，最好始终重启它****)**

docker run --name some-zookeeper --restart always -d zookeeper

**3. 从Zookeeper命令行客户端连接到Zookeeper**

docker run -it --rm --link some-zookeeper:zookeeper zookeeper zkCli.sh -server zookeeper

**3.1 查看根路径**

ls /

**3.2 查看zookeeper节点**

ls /zookeeper

**3.3 创建节点testnode，并关联字符串"zookeeper-test-node"**

create /zookeeper/testnode "zookeeper-test-node"

**3.4 查看节点数据**

get /zookeeper/testnode

**3.5 设置节点内容后再查看**

set /zookeeper/testnode "zookeeper-node"

**3.6 删除节点**

delete /zookeeper/testnode

**3.7 退出客户端**

quit

**4. 创建docker-compose.yml文件**

touch /var/local/docker-compose.yml

**5. 编写docker-compose.yml文件**

vi /var/local/docker-compose.yml

**添加如下内容**

version: '3.1'
    
    services:
      zoo1:
        image: zookeeper
        restart: always
        hostname: zoo1
        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
        restart: always
        hostname: zoo2
        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
        restart: always
        hostname: zoo3
        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

**6. 运行Zookeeper( 3.5将以[复制模式][https_zookeeper.apache.org_doc_current_zookeeperStarted.html]启动Zookeeper，注意：Zookeeper 3.4的`ZOO_SERVERS`格式略有不同****)，并等待它完全初始化。端口`2181-2183`将被暴露**

docker-compose -f /var/local/docker-compose.yml up
    或
    docker stack deploy -c /var/local/docker-compose.yml zookeeper

**7. 查看启动的容器**

docker ps

**8. 连接集群**

nc -vz host-ip 2181

**到此集群配置完成**
