部署Canal-Admin

---

1. 拉取Canal-Admin镜像

为了兼容MYSQL8.0+， 我们需要拉取 v1.1.7的镜像

docker pull canal/canal-admin:v1.1.7

2. 创建目录

mkdir -p /data/canal-server/conf/

3. 创建canal_manager数据库

CREATE DATABASE /*!32312 IF NOT EXISTS*/ `canal_manager` /*!40100 DEFAULT CHARACTER SET utf8 COLLATE utf8_bin */;

USE `canal_manager`;

SET NAMES utf8;
SET FOREIGN_KEY_CHECKS = 0;

COMMIT;

SET FOREIGN_KEY_CHECKS = 1;

4. 启动Canal-Admin

如果是服务器部署的话，记得开放对应的端口号 8089:8089

docker run -d --name canal-admin -p 8089:8089 canal/canal-admin:v1.1.7

5. 拷贝配置文件

docker cp canal-admin:/home/admin/canal-admin/conf/application.yml /data/canal-admin/conf/

6. 删除Canal-Admin容器

docker rm -f canal-admin

7. 修改配置文件

（注意修改注释位置的信息） 一共3处修改

server:
  port: 8089
spring:
  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8

spring.datasource:
  address: xxx.xxx.xxx.xxx:3306   	#创建数据库canal_manager的地址及端口号
  database: canal_manager			 
  username: root					#数据库账号
  password: xxxxxx					#数据库密码
  driver-class-name: com.mysql.jdbc.Driver
  url: jdbc:mysql://${spring.datasource.address}/${spring.datasource.database}?useUnicode=true&characterEncoding=UTF-8&useSSL=false
  hikari:
    maximum-pool-size: 30
    minimum-idle: 1

canal:
  adminUser: admin
  adminPasswd: admin

8. 部署Canal-Admin

docker run --name canal-admin -p 8089:8089 \
-v /data/canal-admin/conf/application.yml:/home/admin/canal-admin/conf/application.yml \
-v /data/canal-admin/logs/:/home/admin/canal-admin/logs/ \
-d canal/canal-admin:v1.1.7

9. 访问Canal-Admin

访问 xxx.xxx.xxx.xxx:8089, 前面换成自己的服务器、虚拟机地址

部署Canal-Server

---

0. 前置工作

查看MYSQL是否 开启log_bin日志 和 日志记录格式 是否为Row
一般都是开启的, 可以通过下列命令在 Navicat 或其他数据库工具进行查看

show variables like 'log_bin';
show variables like 'binlog_format';

授权账号权限， 复制下列命令执行即可

CREATE USER canal IDENTIFIED BY 'canal';  
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
FLUSH PRIVILEGES;

1. 拉取Canal-Server镜像

docker pull canal/canal-server:v1.1.7

2. 创建目录

mkdir -p /data/canal-server/conf/

3. 启动Canal-Server

如果是服务器部署的话，记得开放对应的端口号 11111:11111

docker run -d --name canal-server -p 11111:11111 canal/canal-server:v1.1.7

4. 拷贝配置文件

docker cp canal-server:/home/admin/canal-server/conf/canal.properties /data/canal-server/conf/
docker cp canal-server:/home/admin/canal-server/conf/example/instance.properties /data/canal-server/conf/

7. 部署Canal-Server

docker run --name canal-server -p 11111:11111 \
-v /data/canal-server/conf/instance.properties:/home/admin/canal-server/conf/example/instance.properties \
-v /data/canal-server/conf/canal.properties:/home/admin/canal-server/conf/canal.properties \
-v /data/canal-server/logs/:/home/docker/canal-server/logs/ \
-d canal/canal-server:v1.1.7

部署Canal-Adapter

---

由于这个 Canal-Adapter 作者并没有上传对应的镜像
但是他上传了对应的 tar ，所以我们可以制作对应的镜像
Canal-Adapter 的下载链接： Canal-Adapter

1. 创建对应的文件，文件如下

路径尽量跟我的一致 /opt/canal/ ，因为后面的文件都是在这个路径下

2. 对应的文件内容如下

Dockerfile

FROM openjdk:11
COPY canal.adapter-*.tar.gz /tmp/
	
RUN \
    mkdir -p /opt/canal-adapter && \
    tar -zxf /tmp/canal.adapter-*.tar.gz -C /opt/canal-adapter && \
    rm -r /tmp/canal.adapter-*.tar.gz

COPY startup.sh /opt/canal-adapter/bin/startup.sh

WORKDIR /opt/canal-adapter

CMD ["sh", "-c", "sh /opt/canal-adapter/bin/startup.sh && tail -F logs/adapter/adapter.log"]

startup.sh

9. 部署Canal-Adapter

docker run --name canal-adapter -p 8081:8081 \
