SpringCloud(Nacos)-整合docker+zookeeper+kafka+canal(单机)-宝塔linux
SpringCloud(Nacos)-整合docker+zookeeper+kafka+canal(单机)-宝塔linux
①拉取镜像
docker pull canal/canal-server:v1.1.4
docker pull zookeeper
docker pull wurstmeister/kafka
一、zookeeper
①启动zookeeper(端口2181)
docker run -d --name zookeeper -p 2181:2181 --restart always zookeeper
二、kafka
①启动kafka(端口9092)
docker run -d --name kafka -p 9092:9092 -e KAFKA_BROKER_ID=0 -e KAFKA_ZOOKEEPER_CONNECT=[zkIP:端口] -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://[对外暴露的IP:端口] -e KAFKA_LISTENERS=PLAINTEXT://[建立链接的IP:端口] -t wurstmeister/kafka
- [zkIP:端口]:我的IP:2181
- [对外暴露的IP:端口]:我的IP:9092
- [建立链接的IP:端口]:0.0.0.0:9092
②初始化kafka(进入opt/kafka/bin)
cd opt/kafka/bin
1、创建主题
kafka-topics.sh --create --zookeeper [zkIP]:[zk端口] --replication-factor 1 --partitions 1 --topic [主题名称]
2、创建生产者(订阅主题)
kafka-console-producer.sh --broker-list [kafkaIP]:9092 --topic [主题名称]
3、创建消费者(完成全部配置,依次启动zk、kafka、canal后就可以消费信息、这里提前记录、等下面配置完canal再创建消费者。)
kafka-console-consumer.sh --bootstrap-server [kafkaIP]:9092 --topic [主题名称]
③zookeeper可视化工具ZooInspector
在build目录下cmd输入启动命令java -jar zookeeper-dev-ZooInspector.jar
初始化kafka后可以看到主题(topic)等信息
三、canal(安装步骤)
配置canal.properties
# tcp, kafka, RocketMQ
canal.serverMode = kafka
canal.mq.servers = [kafkaIP]:[kafka端口]
配置instance.properties
# 数据库地址
canal.instance.master.address=[mysqlIP]:3306
# binlog日志名称
canal.instance.master.journal.name=[binlog名称]
# mysql主库链接时起始的binlog偏移量
canal.instance.master.position=[起始偏移量]
# 在MySQL服务器授权的账号密码
canal.instance.dbUsername=[username]
canal.instance.dbPassword=[password]
# mq config
canal.mq.topic=[主题名]
# dynamic topic route by schema or table regex
#canal.mq.dynamicTopic=mytest1.user,mytest2\\..*,.*\\..*
canal.mq.partition=0
# hash partition config
#canal.mq.partitionsNum=3
#canal.mq.partitionHash=test.table:id^name,.*\\..*
#################################################
①启动canal(端口11111)
docker run --name canal -p 11111:11111 -d -v /home/canal/instance.properties:/home/admin/canal-server/conf/example/instance.properties -v /home/canal/canal.properties:/home/admin/canal-server/conf/canal.properties canal/canal-server:v1.1.4
- -v 映射配置文件
四、测试
①创建消费者(完成全部配置,依次启动zk、kafka、canal后就可以消费信息)
kafka-console-consumer.sh --bootstrap-server [kafkaIP]:9092 --topic [主题名称]
成功消费信息!
五、SpringCloud集成
注意依赖版本,以下是我的版本(踩坑了,搞了半天最后是版本不兼容)
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.5.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-stream-kafka</artifactId>
<version>3.0.8.RELEASE</version>
</dependency>
配置application.yml
spring:
cloud:
nacos:
discovery:
server-addr: [nacosIP]:8848
stream:
kafka:
binder:
brokers:
- [kafkaIP]:9092
auto-add-partitions: true
auto-create-topics: true
zk-nodes:
- [zkIP]:2182
bindings:
#配置自己定义的通道与哪个中间件交互
#ShopChannel里Input和Output的值
shop_input:
destination: [topicName] #目标主题
shop_output:
destination: [topicName]
default-binder: kafka #默认的binder是kafka
定义接口(spring-cloud-stream已经给我们定义了最基本的输入与输出接口,他们分别是 Source,Sink, Processor)
public interface Sink {
String INPUT = "input";
@Input("input")
SubscribableChannel input();
}
public interface Source {
String OUTPUT = "output";
@Output("output")
MessageChannel output();
}
public interface Processor extends Source, Sink {
}
public interface ShopChannel {
/**
* 发消息的通道名称
*/
String SHOP_OUTPUT = "shop_output"; //application.yml
/**
* 消息的订阅通道名称
*/
String SHOP_INPUT = "shop_input"; //application.yml
/**
* 发消息的通道
* @return
*/
@Output(SHOP_OUTPUT)
MessageChannel sendShopMessage();
/**
* 收消息的通道
* @return
*/
@Input(SHOP_INPUT)
SubscribableChannel receiveShopMessage();
}
创建服务(canal消费者)
@Component
@Slf4j
public class KafkaReceiver {
@StreamListener(value = ShopChannel.SHOP_INPUT)
public void receive(Message<String> message) {
System.out.println(message.getPayload());
}
}
启动类(添加注解@EnableBinding(ShopChannel.class))
@SpringBootApplication
@EnableDiscoveryClient
@EnableBinding(ShopChannel.class)
@Slf4j
public class ZqyCanalApplication {
public static void main(String[] args) {
ConfigurableApplicationContext application = SpringApplication.run(ZqyCanalApplication.class, args);
Environment env = application.getEnvironment(); //环境
String port = env.getProperty("server.port");
log.info("\n----------------------------------------------------------\n\t" +
"Service of Canal is running!" +
"\n----------------------------------------------------------");
}
}
启动测试
成功消费信息!

用canal解析MySQLBinlog日志发送到Kafka
Canal——canal server 读取 binlog 到 kafka 然后在使用 canal-adapter
感谢大佬!
