1. 集群规划

点击查看【processon】

• 网络创建

  sudo docker network create --driver bridge --subnet=172.18.0.0/16 --gateway=172.18.0.1 zknet
  sudo docker network ls
  sudo docker network inspect zknet

  2. 获取镜像

  # 查看可用的稳定版本
  sudo docker search zookeeper
  sudo docker pull zookeeper:3.4.10
  sudo docker image ls |grep -E 'zookeeper'

  3. 准备工作

  # 存储卷目录创建
  mkdir -p /usr/local/zkCluster/node1
  mkdir -p /usr/local/zkCluster/node2
  mkdir -p /usr/local/zkCluster/node3
  

  4. 启动容器

• 创建容器 ```bash sudo docker run -d -p 2181:2181 —name zookeeper_node1 —privileged —restart always \ —network zknet —ip 172.18.0.101 \ -v /usr/local/zkCluster/node1/volumes/data:/data \ -v /usr/local/zkCluster/node1/volumes/datalog:/datalog \ -v /usr/local/zkCluster/node1/volumes/logs:/logs \ -e ZOO_MY_ID=1 \ -e “ZOO_SERVERS=server.1=172.18.0.101:2888:3888 server.2=172.18.0.102:2888:3888 server.3=172.18.0.103:2888:3888” \ zookeeper:3.4.10

sudo docker run -d -p 2182:2181 —name zookeeper_node2 —privileged —restart always \ —network zknet —ip 172.18.0.102 \ -v /usr/local/zkCluster/node2/volumes/data:/data \ -v /usr/local/zkCluster/node2/volumes/datalog:/datalog \ -v /usr/local/zkCluster/node2/volumes/logs:/logs \ -e ZOO_MY_ID=2 \ -e “ZOO_SERVERS=server.1=172.18.0.101:2888:3888 server.2=172.18.0.102:2888:3888 server.3=172.18.0.103:2888:3888” \ zookeeper:3.4.10

sudo docker run -d -p 2183:2181 —name zookeeper_node3 —privileged —restart always \ —network zknet —ip 172.18.0.103 \ -v /usr/local/zkCluster/node3/volumes/data:/data \ -v /usr/local/zkCluster/node3/volumes/datalog:/datalog \ -v /usr/local/zkCluster/node3/volumes/logs:/logs \ -e ZOO_MY_ID=3 \ -e “ZOO_SERVERS=server.1=172.18.0.101:2888:3888 server.2=172.18.0.102:2888:3888 server.3=172.18.0.103:2888:3888” \ zookeeper:3.4.10

查看容器

sudo docker ps -a |grep -E ‘zookeeper*’

- **启动容器**
```bash
for node in `seq 1 3`; do \
  sudo docker start zookeeper_node${node}; \
done

• 重启容器

  for node in `seq 1 3`; do \
  sudo docker restart zookeeper_node${node}; \
  done
  

• 停止容器

  for node in `seq 1 3`; do \
  sudo docker stop zookeeper_node${node}; \
  done
  

• 删除容器

  for node in `seq 1 3`; do \
  sudo docker rm zookeeper_node${node}; \
  done
  

• 清理数据

  rm -rf /usr/local/zkCluster/node*/*
  rm -rf /usr/local/zkCluster/node2/*
  rm -rf /usr/local/zkCluster/node3/*
  

  5. 验证

  ```bash

  进入容器

  sudo docker exec -it zookeeper_node1 bin/zkCli.sh

查看zk节点状态

sudo docker exec -it zookeeper_node1 bin/zkServer.sh status

查看zk集群状态

for node in seq 1 3; do \ sudo docker exec -it zookeeper_node${node} bin/zkServer.sh status; \ done

查看日志

sudo docker logs zookeeper_node1 sudo docker logs -f -t —tail=50 zookeeper_node1 ```
