一、安装docker

yum install -y docker

二、启动docker镜像

sudo service docker start

三、查找zookeeper镜像

sudo docker search zookeeper

四、下载zookeeper镜像

sudo  docker pull docker.io/zookeeper

 五、下载完后可检查镜像

sudo docker images 

六、创建 /usr/local/docker/zookeeper/docker.compose.yml,并给文件添加如下内容：

version: '2'
services:
    zoo1:
        image: zookeeper
        restart: always
        container_name: zoo1
        ports:
            - "2181:2181"
        environment:
            ZOO_MY_ID: 1
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
 
    zoo2:
        image: zookeeper
        restart: always
        container_name: zoo2
        ports:
            - "2182:2181"
        environment:
            ZOO_MY_ID: 2
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
 
    zoo3:
        image: zookeeper
        restart: always
        container_name: zoo3
        ports:
            - "2183:2181"
        environment:
            ZOO_MY_ID: 3
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

 七、启动docker

sudo systemctl start docker

八、启动服务器集群

docker-compose up -d

 九、查看docker ps
