sleuth + zipkin实现链路追踪

1.下载启动zipkin服务

https://dl.bintray.com/openzipkin/maven/io/zipkin/java/zipkin-server/

我选择的是最新版本
下载 *-exec.jar文件

2.启动zipkin服务器

数据存内存

java -jar zipkin-server-2.12.9-exec.jar

数据存mysql

java -jar zipkin-server-2.12.9-exec.jar  --STORAGE_TYPE=mysql --MYSQL_HOST=192.168.33.10 --MYSQL_TCP_PORT=3306 --MYSQL_DB=zipkin --MYSQL_USER=root --MYSQL_PASS=root

其中
--STORAGE_TYPE=mysql 数据库类型
--MYSQL_HOST=192.168.33.10 数据库地址
--MYSQL_TCP_PORT=3306 数据库端口
--MYSQL_DB=zipkin 数据库名称
--MYSQL_USER=root
--MYSQL_PASS=root

创建相应表
官方建表脚本地址：https://github.com/openzipkin/zipkin/blob/master/zipkin-storage/mysql-v1/src/main/resources/mysql.sql/

1.执行命令后

2.访问管理界面
访问地址： http://localhost:9411/zipkin/
界面如下

3.创建服务调用项目

需要被追踪的服务器都需要进行以下步骤

引入sleuthjar包

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-sleuth-zipkin</artifactId>
            <version>2.1.0.RELEASE</version>
        </dependency>

配置zipkin服务器

spring:
  zipkin:
    base-url: http://localhost:9411/ # zipkin服务器的地址，默认端口9411
    sender:
      type: web  # 设置使用http的方式传输数据
  # sleuth 配置
  sleuth:
    sampler:
      probability: 1 # 设置抽样采集为100%，默认为0.1，即10%

这里我是创建了两个服务，使用的spring cloud feign+nacos进行服务注册和调用具体就不展示了。启动程序进行调用，Zipkin管理界面查询
