docker 安装canal

今天的接口写完了吗？2024-04-11 9:39

一、新建文件夹

新建文件夹logs, 新建文件canal.properties instance.properties docker.compose.yml

canal.propertie 修改如下：

修改instance.properties内容如下

1.1 canal.properties

1.3 docker.compose.yml

复制代码 
version: '3'
services:
  canal:
    container_name: canal_latest
    image: canal/canal-server:v1.1.5
    restart: always
    ports:
      - 11111:11111
    volumes:                                
      - ./canal.properties:/home/admin/canal-server/conf/canal.properties
      - ./instance.properties:/home/admin/canal-server/conf/example/instance.properties
      - ./logs:/home/admin/canal-server/logs

二、启动容器 ：先进入canal 目录

复制代码 
docker-compose up -d

三、 手动创建一个交换机 ，名字和配置文件保持一致

然后绑定一个消息队列，修改自己配置的mysql 数据

观察消息队列
