基于docker多机器zk集群搭建

基于docker多机器zk集群搭建

在3台机器上创建zk目录

sudo mkdir -p /usr/local/zookeeper/conf sudo mkdir -p /usr/local/zookeeper/data sudo mkdir -p /usr/local/zookeeper/logs

在conf下每台机器 下创建 zoo.cfg

vim /usr/local/zookeeper/conf/zoo.cfg nitLimit=5 syncLimit=2 dataDir=/data dataLogDir=/datalog clientPort=2181 maxClientCnxns=60 server.1=0.0.0.0:2888:3888 server.2=xxx.xxx.xxx.xxx:2888:3888 server.3=xxx.xxx.xxx.xxx:2888:3888

每台机器配置区别是 假设当前机器是server.1 那么当前机器的ip填0.0.0.0

以此类推。

在docker swarm Leader机器下创建 网关

sudo docker network create -d overlay \ --subnet=10.10.0.0/16 \ --gateway=10.10.0.254 \ --attachable=true \ Overlay

在portainer 上创建任务执行下面的命令

version: '3.3' services: zoo1: image: zookeeper restart: always hostname: zoo1 volumes: - /usr/local/zookeeper/data:/data - /usr/local/zookeeper/logs:/logs networks: - overlay 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 volumes: - /usr/local/zookeeper/data:/data - /usr/local/zookeeper/logs:/logs networks: - overlay 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 volumes: - /usr/local/zookeeper/data:/data - /usr/local/zookeeper/logs:/logs networks: - overlay 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 networks: overlay: external: true

命令执行完后效果
