部署zipkin服務(wù)，配合sleuth進(jìn)行調(diào)用分析

簡介

zipkin是Twitter的開源的分布式跟蹤系統(tǒng)脸狸，基于Dapper的論文設(shè)計而來最仑。主要功能就是收集系統(tǒng)的調(diào)用數(shù)據(jù)，進(jìn)行分析.論文參考http://bigbully.github.io/Dapper-translation/,其實現(xiàn)框架如下：

開工

1. 各系統(tǒng)添加zipkin依賴

    <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zipkin</artifactId>
   </dependency>

2. application.yml中添加zipkin配置

spring:
  Jackson:
    serialization:
      indent-output: true
  application:
    name: udm-server
  zipkin:
#我本地部署的zipkin服務(wù)用的9411端口
    base-url: http://localhost:9411
  sleuth:
    sampler:
      percentage: 1.0

3. 新建zipkin-dog項目module炊甲，我們將采用mysql作為數(shù)據(jù)存儲（不配置盯仪，默認(rèn)會存儲到內(nèi)存中），本次未集成mq或kafka等異步組件蜜葱，有需要后續(xù)會介紹全景，依賴添加

4. 更新zipkin-dog到application.yml配置文件,我用的本地mysql數(shù)據(jù)庫

server:
  port: 9411
spring:
  datasource:
    driver-class-name:  com.mysql.jdbc.Driver
    url: jdbc:mysql://local.p2.cn:3306/zipkin
    username: root
    password: yeepay.com
zipkin:
  storage:
    type: mysql

5. 附加步，去掉udm-client中的當(dāng)時的自定義負(fù)載均衡配置牵囤，測試發(fā)現(xiàn)配置了自定義的負(fù)載后爸黄，再集成zipkin，feign有偶爾找不到服務(wù)的bug揭鳞，所以去掉

#udm-server:
#  NFLoadBalancerRuleClassName: com.netflix.loadbalancer.RandomRule


---
@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients(basePackages = "open.template.work.udm.client.feign")
@EnableHystrix
public class UdmClientApplication {

    public static void main(String[] args) {
        SpringApplication.run(UdmClientApplication.class, args);
    }

//
//  @Bean
//  public IRule ribbonRoundRobinRule() {
//      return new RandomRule();
//  }


}

6.啟動zipkin-dog炕贵，重啟其他各相應(yīng)服務(wù)，切記所有需要zipkin記錄調(diào)用鏈的服務(wù)都要添加1野崇、2步的配置

7. 驗收

   
   
   zipkin展示

再次重啟zipkin-dog称开，數(shù)據(jù)依然存在，查看數(shù)據(jù)庫已有請求數(shù)據(jù)乓梨，但spanid可能和日志打印不太一樣鳖轰，因為日志打印未16進(jìn)制，數(shù)據(jù)庫存儲為bigint扶镀。

8. 附蕴侣，為了提高性能可以集成mq或kafka等異步組件，本章暫未展示

完工臭觉！
