docker pull zookeeperzookeeper 集群的搭建
创建名为docker-compose.yml的文件
输入以下内容
version: '2' services: zk1: image: zookeeper restart: always container_name: zk1 ports: - "2181:2181" environment: ZOO_MY_ID: 1 ZOO_SERVERS: server.1=zk1:2888:3888 server.2=zk2:2888:3888 server.3=zk3:2888:3888 zk2: image: zookeeper restart: always container_name: zk2 ports: - "2182:2181" environment: ZOO_MY_ID: 2 ZOO_SERVERS: server.1=zk1:2888:3888 server.2=zk2:2888:3888 server.3=zk3:2888:3888 zk3: image: zookeeper restart: always container_name: zk3 ports: - "2183:2181" environment: ZOO_MY_ID: 3 ZOO_SERVERS: server.1=zk1:2888:3888 server.2=zk2:2888:3888 server.3=zk3:2888:3888
这个配置文件会告诉 Docker 分别运行三个 zookeeper 镜像, 并分别将本地的 2181, 2182, 2183 端口绑定到对应的容器的2181端口上.
ZOO_MY_ID 和 ZOO_SERVERS 是搭建 ZK 集群需要设置的两个环境变量, 其中 ZOO_MY_ID 表示 ZK 服务的 id, 它是1-255 之间的整数, 必须在集群中唯一. ZOO_SERVERS 是ZK 集群的主机列表.
运行zookeeper集群
当前目录下输入命令 COMPOSE_PROJECT_NAME=zk_cluster docker-compose up -d
大功告成！
