k8s 部署 canal 集群,RocketMQ 模式
前提
MySQL
开启 binlog 的 MySQL 服务器:192.168.59.1:3306
ini
[mysqld]
log-bin=mysql-bin # 开启 binlog
binlog-format=ROW # 选择 ROW 模式
server_id=1 # 配置 MySQL replaction 需要定义,不要和 canal 的 slaveId 重复
具有 slave 权限的账号:用户名 canal,密码:canal
sql
CREATE USER canal IDENTIFIED BY 'canal';
-- GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
GRANT ALL PRIVILEGES ON *.* TO 'canal'@'%' ;
FLUSH PRIVILEGES;
RocketMQ
RocketMQ 地址:192.168.56.1:9876
创建 tipoc:canal_test

制作 canal-admin、canal-server 镜像
由于 canal:v1.1.7 有一个 bug com.alibaba.otter.canal.server.embedded.CanalServerWithEmbedded isn't start , please check · Issue #4930,而官方已经在 Release 1.1.8-alpha 中修复了这个问题,但没有发布官方的 docker 镜像,所以需要自己制作镜像。以下是我制作的镜像,已发布到 dockerhub,可直接使用
zhaobingshuang/canal-admin:v1.1.8-alpha
zhaobingshuang/canal-server:v1.1.8-alpha
部署 zookeeper
zk-configmap.yaml
数据目录配置为 /data
yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: zk-configmap

执行以下命令
shell
kubectl apply -f zk-configmap.yaml
kubectl apply -f zk-pvc.yaml
kubectl apply -f zk-deployment.yaml
kubectl apply -f zk-service.yaml
打开 kubernetes-dashboard,进入 zk pod 验证。
执行 create /cluster_1
创建 znode,为之后 canal-admin 创建集群使用。
部署 canal-admin
执行 manager.sql 初始化数据库。

执行以下命令
shell
kubectl apply -f canal-admin-configmap.yaml
kubectl apply -f canal-admin-deployment.yaml
kubectl apply -f canal-admin-service.yaml
kubectl apply -f canal-admin-ingress.yaml
zhaobingshuang/canal-admin:v1.1.8-alpha 镜像比较大,需要等待一段时间等待,等 pod canal-admin 启动后,浏览器访问 http://canal-admin.com/。
用户名:admin,密码:123456
创建集群,集群名称:cluster_1 ,ZK 地址:zk:2181/cluster_1
点击主配置 -> 载入模板
修改以下配置:
properties
canal.zkServers =zk:2181/cluster_1
canal.serverMode = rocketMQ
canal.instance.global.spring.xml = classpath:spring/default-instance.xml
rocketmq.namesrv.addr = 192.168.56.1:9876
rocketmq.tag =canal
部署 canal-server

测试
载入模板,修改以下配置之后保存:
properties
canal.instance.master.address=192.168.59.1:3306
canal.instance.dbUsername=canal
canal.instance.dbPassword=canal
canal.instance.filter.regex=test\\..*
canal.mq.topic=canal_test
启动实例
执行以下 SQL,创建数据库、创建表、插入数据:
sql
CREATE DATABASE IF NOT EXISTS test;
USE test;
CREATE TABLE `table_1` (
`id` int NOT NULL,
`name` varchar(50) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
INSERT INTO table_1 VALUES(1, 'tom');
INSERT INTO table_1 VALUES(2, 'jack')
