用于Docker Compose部署ZooKeeper集群的yaml文件：
version: '3'networks: zookeeper-networks: driver: bridgeservices: zookeeper1: image: zookeeper container_name: zookeeper1 restart: always ports: - 9001:2181 volumes: - "/usr/local/docker-compose/zookeeper/zookeeper1/data:/data" - "/usr/local/docker-compose/zookeeper/zookeeper1/datalog:/datalog" - "/usr/local/docker-compose/zookeeper/zookeeper1/logs:/logs" - "/usr/local/docker-compose/zookeeper/zookeeper1/conf:/conf" environment: ZOO_MY_ID: 1 ZOO_SERVERS: server.1=zookeeper1:2888:3888 server.2=zookeeper2:2888:3888 server.3=zookeeper3:2888:3888 networks: - zookeeper-networks zookeeper2: image: zookeeper container_name: zookeeper2 restart: always ports: - 9002:2181 volumes: - "/usr/local/docker-compose/zookeeper/zookeeper2/data:/data" - "/usr/local/docker-compose/zookeeper/zookeeper2/datalog:/datalog" - "/usr/local/docker-compose/zookeeper/zookeeper2/logs:/logs" - "/usr/local/docker-compose/zookeeper/zookeeper2/conf:/conf" environment: ZOO_MY_ID: 2 ZOO_SERVERS: server.1=zookeeper1:2888:3888 server.2=zookeeper2:2888:3888 server.3=zookeeper3:2888:3888 networks: - zookeeper-networks zookeeper3: image: zookeeper container_name: zookeeper3 restart: always ports: - 9003:2181 volumes: - "/usr/local/docker-compose/zookeeper/zookeeper3/data:/data" - "/usr/local/docker-compose/zookeeper/zookeeper3/datalog:/datalog" - "/usr/local/docker-compose/zookeeper/zookeeper3/logs:/logs" - "/usr/local/docker-compose/zookeeper/zookeeper3/conf:/conf" environment: ZOO_MY_ID: 3 ZOO_SERVERS: server.1=zookeeper1:2888:3888 server.2=zookeeper2:2888:3888 server.3=zookeeper3:2888:3888 networks: - zookeeper-networks
创建用于存放配置文件的目录：
mkdir -p /usr/local/docker-compose/zookeeper/zookeeper1/conf /usr/local/docker-compose/zookeeper/zookeeper2/conf /usr/local/docker-compose/zookeeper/zookeeper3/con
创建配置文件：
vim /usr/local/docker-compose/zookeeper/zookeeper1/conf/zoo.cfg
配置文件的内容如下所示：
tickTime=2000initLimit=10syncLimit=5dataDir=/datadataLogDir=/datalogclientPort=2181# 扩展类型启用，设置为true才能创建TTL类型的节点extendedTypesEnabled=true# 集群配置server.1=zookeeper1:2888:3888server.2=zookeeper2:2888:3888server.3=zookeeper3:2888:3888
tickTime：ZooKeeper中最小的时间单位长度 （默认2000ms）。initLimit：follower节点启动后与leader节点完成数据同步的时间（指定为tickTime的倍数，默认10倍，即20s）。syncLimit：leader节点和follower节点进行心跳检测的最大延迟时间（指定为tickTime的倍数，默认5倍，即10s）。dataDir：表示ZooKeeper存储快照文件的目录（默认为/tmp/zookeeper）。dataLogDir：表示ZooKeeper事务日志的存储路径，默认指定在dataDir目录下 。clientPort：表示ZooKeeper客户端和ZooKeeper服务端建立连接的端口号（默认 2181）。
将配置文件复制到其他ZooKeeper节点挂载的配置文件目录：
cp /usr/local/docker-compose/zookeeper/zookeeper1/conf/zoo.cfg /usr/local/docker-compose/zookeeper/zookeeper2/conf/cp /usr/local/docker-compose/zookeeper/zookeeper1/conf/zoo.cfg /usr/local/docker-compose/zookeeper/zookeeper3/conf/
开始部署ZooKeeper集群：
docker compose -f /root/composefile/zookeeper/zookeeper.yaml up -d
-f指定yaml文件位置，-d表示后台运行。
docker ps和docker compose ls命令都可以查询服务是否启动成功：
Docker部署在192.168.1.9上。
使用另外一台有ZooKeeper文件的虚拟机进行测试。
./zkCli.sh -timeout 5000 -server 192.168.1.9:9001
测试创建TTL类型的节点。
