docker安装canal-server(v.1.1.8)【mysql-＞rabbitMQ】

查看版本

https://hub.docker.com/r/canal/canal-server/tags

拉取镜像

docker pull canal/canal-server:v1.1.8

准备 MySql

准备mysql的同步账号（canal/Canal@123）

-- 创建账号（用户名：canal，密码：Canal@123456，根据实际修改）
CREATE USER 'canal'@'%' IDENTIFIED BY 'Canal@123';
-- 授权（允许读取所有库的 binlog）
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
-- 刷新权限
FLUSH PRIVILEGES;

查看mysql是否开启binlog

show variables like 'log_bin'; -- 结果为 ON 表示开启
show variables like 'binlog_format'; -- 结果为 ROW 表示正确
show master status; -- 查看当前 binlog 位点（后续 Canal 配置可能用到）

准备 RabbitMQ

地址 rabbitmq.4.1.4:5672 （注：docker网络下直接用容器名称代替ip,端口为宿主机内的端口）

账号/密码 admin/Admin@123

直连交换机 to.canal.exchange

docker-compose

启动容器生成配置文件

docker run -p 11111:11111 --name canal-server.1.1.8 -d canal/canal-server:v1.1.8

复制宿主机文件

docker cp canal:/home/admin/canal-server/conf ./

结果如下

停止并删除容器（目的以docker-compose 启动）

docker stop canal-server.1.1.8

docker rm canal-server.1.1.8

创建docker-compose.yml文件

docker-compose.yml

内容

services:
  canal-server:
    image: canal/canal-server:v1.1.8
    container_name: canal-server.1.1.8
    restart: unless-stopped
    ports:
      - "11111:11111"    # Canal服务端口
      - "11112:11112"    # 监控指标端口
    volumes:
      - ./logs/:/home/admin/canal-server/logs #日志信息
      - ./conf/:/home/admin/canal-server/conf #配置文件
    networks:
      - universal-network

networks:
  universal-network:
    external: true
    name: universal-network

结果如下

在canal 配置mysql，并将数据输出到rabbmq中（注意：已经提前在docker 同网络(universal-network)下安装了mysql与rabbitmq）
