How to integrate Zipkin distributed log tracking in Spring Cloud Alibaba to check log link, increase development efficiency, and track back bugs

1. The installation of kafka

Installation address: kafka.apache.org/quickstart suggest installation kafka_2. 13 – version 2.7.0

CD Installation package directory

Open zooper(kafa depends on ZK, so open ZK first)

bin/zookeeper-server-start.sh config/zookeeper.properties  
Copy the code

Open the kafka

bin/kafka-server-start.sh  config/server.properties      
Copy the code

2. Install zipkin

IO /pages/quick…

Import SQL, create mysql table, make zinKin data persistent

Copy the code

Start ZipKin and connect to the database and Kafka:

Java -dkafka_bootstrap_Servers =127.0.0.1:9092 -jar zipkin.jar --STORAGE_TYPE=mysql --MYSQL_HOST=120.77.213.159 --MYSQL_TCP_PORT=3307 --MYSQL_USER=root --MYSQL_PASS=abc123456 --MYSQL_DB=imooc_e_commerceCopy the code

3. Write configuration files into Spring Cloud Alibaba

Introduced in pom.xml in the microservices you need ZinKin

 
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.kafka</groupId>
    <artifactId>spring-kafka</artifactId>
    <version>2.5.0. RELEASE</version>
</dependency>
 
Copy the code

Introduce the ZipKin configuration in the configuration file

spring:
    kafka:
      bootstrap-servers: 127.0. 01.: 9092
      producer:
        retries: 3
      consumer:
        auto-offset-reset: latest
    sleuth:
      sampler:
        # Sampling strategy
        probability: 1.0   Sample ratio 1.0 means 100%, default is 0.1
        # speed acquisition, Spring sleuth. Sampler. Aim-listed probability attribute value is invalid
        rate: 100 Nice spacing accepts trace amount
Copy the code

The final stage, testing

In your introduction zipkin service, send a few requests Then open the: http://127.0.0.1:9411/zipkin/ can see you

The link data and logs are displayed, and you are done
