zookeeper集群部署

服务器：centos7，已安装docker，docker-compose

第一步：服务器上创建三个文件夹

 

 第二步：创建一个命名为docker-compose.yml的文件，复制下面内容

version: '3.1'

services:
zoo1:
image: zookeeper
restart: always
privileged: true
hostname: zoo1
ports:
- 2181:2181
volumes: # 挂载数据
- /usr/local/zookeeper-cluster/node4/data:/data
- /usr/local/zookeeper-cluster/node4/datalog:/datalog
environment:
ZOO_MY_ID: 4
ZOO_SERVERS: server.4=0.0.0.0:2888:3888;2181 server.5=zoo2:2888:3888;2181 server.6=zoo3:2888:3888;2181
networks:
default:
ipv4_address: 172.18.0.14

zoo2:
image: zookeeper
restart: always
privileged: true
hostname: zoo2
ports:
- 2182:2181
volumes: # 挂载数据
- /usr/local/zookeeper-cluster/node5/data:/data
- /usr/local/zookeeper-cluster/node5/datalog:/datalog
environment:
ZOO_MY_ID: 5
ZOO_SERVERS: server.4=zoo1:2888:3888;2181 server.5=0.0.0.0:2888:3888;2181 server.6=zoo3:2888:3888;2181
networks:
default:
ipv4_address: 172.18.0.15

zoo3:
image: zookeeper
restart: always
privileged: true
hostname: zoo3
ports:
- 2183:2181
volumes: # 挂载数据
- /usr/local/zookeeper-cluster/node6/data:/data
- /usr/local/zookeeper-cluster/node6/datalog:/datalog
environment:
ZOO_MY_ID: 6
ZOO_SERVERS: server.4=zoo1:2888:3888;2181 server.5=zoo2:2888:3888;2181 server.6=0.0.0.0:2888:3888;2181
networks:
default:
ipv4_address: 172.18.0.16

networks: # 自定义网络
default:
external:
name: zoonet

第三步：进入该文件所在位置，执行命令

docker-compose -f docker-compose.yml up -d

执行成功结果

 

 安装zookeeper集群成功

备注：记得要开放端口2181，2182，2183

查看那个zookeeper是leader
