canal-admin 集群搭建

• 参考地址：https://blog.csdn.net/qq_24950043/article/details/127187547

• 使用场景：为了解决公司多业务缓存一致性问题采用的一种方案

一 通过docker-compose 快速搭建

安装 canal-admin

• zoo.cfg 配置文件

dataDir=/data
dataLogDir=/datalog
tickTime=2000
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
standaloneEnabled=true
admin.enableServer=true
server.1=zk1:2888:3888;2181

• docker-compose.yml配置文件

version: "3.1"
services:
  canal-admin:
    image: "canal/canal-admin:v1.1.5"
    privileged: true
    restart: always
    container_name: canal-admin
    environment:
      - TZ=Asia/Shanghai
      - server.port=8089
      - canal.adminUser=admin
      - canal.adminPasswd=123456
    ports:
      - "8089:8089"

安装 zookeeper

• docker-compose.yml 配置文件

version: '3'
services:
  zk1:
    image: zookeeper:3.6
    restart: always
    container_name: zk1
    hostname: zk1
    # 给docker容器给超级权限，访问宿主机目录
    privileged: true
    ports:
      - 2181:2181
      - 2888:2888
      - 3888:3888
    environment:
      # 当前zk实例的id
      ZOO_MY_ID: 1
      # 整个zk集群的机器端口列表（2181：对client端提供服务的端口，3888：选举leader使用，2888：集群内机器通讯使用（Leader监听此端口））
    volumes:
      - '/docker/zookeeper/data:/data'
      - '/docker/zookeeper/datalog:/datalog'
      - '/docker/zookeeper/conf:/conf'

canal-server-1 部署

docker-composer.yml

version: "3.1"
services:
  canal:
    image: "canal/canal-server:v1.1.5"
    privileged: true
    restart: always
    container_name: canal
    environment:
      - TZ=Asia/Shanghai
      - canal.register.ip=192.168.2.150
      - canal.admin.manager=192.168.2.150:8089
      - canal.admin.port=11110
      - canal.admin.user=admin
      # 密码 canal-admin 配置的密码 SELECT PASSWORD({canal.adminPasswd}) 获取
      - canal.admin.passwd=6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9
      - canal.admin.register.name=node1
      - canal.admin.register.auto=true
      - canal.admin.register.cluster=zoo
    volumes:
      - '/docker/canal/logs:/home/admin/canal-server/logs'
    ports:
      - "11111:11111"
      - "11110:11110"
      - "11112:11112"
      - "9100:9100"
