前言：
2.x 之后官方不再建议自定义zipkin，官方提供的zipkin.jar包：https://dl.bintray.com/openzipkin/maven/io/zipkin/java/zipkin-server;
当然官方打包好的jar集合了各种场景和配置不一定适合当前项目环境，所以大部分情况下还是需要自己搭建服务，话不多说，直接开干：
环境：
jdk:1.8
spring boot: 2.0.9
mysql: 5.7

- 启动类配置 注意需要注解@EnableZipkinServer 开启zipkin服务
package com.server.cloud.zipkin;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import zipkin2.server.internal.EnableZipkinServer;
@SpringBootApplication
@EnableZipkinServer
public class ZipkinServerApplication {
public static void main(String[] args) {
SpringApplication.run(ZipkinServerApplication.class, args);
}
}

启动服务...此时一个简单的基于MySQL的链路追踪zipkin服务配置完成：
