Zipkin简介
Zipkin是什么 Zipkin的官方介绍：https://zipkin.io/
Zipkin是一款开源的分布式实时数据追踪系统（Distributed Tracking System），基于 Google Dapper的论文设计而来，由 Twitter 公司开发贡献。其主要功能是聚集来自各个异构系统的实时监控数据。分布式跟踪系统还有其他比较成熟的实现，例如：Naver的Pinpoint、Apache的HTrace、阿里的鹰眼Tracing、京东的Hydra、新浪的Watchman，美团点评的CAT，skywalking等。
为什么用Zipkin 随着业务越来越复杂，系统也随之进行各种拆分，特别是随着微服务架构和容器技术的兴起，看似简单的一个应用，后台可能有几十个甚至几百个服务在支撑；一个前端的请求可能需要多次的服务调用最后才能完成；当请求变慢或者不可用时，我们无法得知是哪个后台服务引起的，这时就需要解决如何快速定位服务故障点，Zipkin分布式跟踪系统就能很好的解决这样的问题。
Zipkin的一些基本概念？
Brave Brave 是用来装备 Java 程序的类库，提供了面向 Standard Servlet、Spring MVC、Http Client、JAX RS、Jersey、Resteasy 和 MySQL 等接口的装备能力，可以通过编写简单的配置和代码，让基于这些框架构建的应用可以向 Zipkin报告数据。同时 Brave 也提供了非常简单且标准化的接口，在以上封装无法满足要求的时候可以方便扩展与定制。
如下图是 Brave 的结构图。Brave 利用 reporter 向 Zipkin的 Collector 发送 trace 信息。
Brave 主要是利用拦截器在请求前和请求后分别埋点。例如 Spingmvc 监控使用 Interceptors，Mysql 监控使用 statementInterceptors。同理 Dubbo 的监控是利用 com.alibaba.dubbo.rpc.Filter 来过滤生产者和消费者的请求。
traceId 一次请求全局只有一个traceId。用来在海量的请求中找到同一链路的几次请求。比如servlet服务器接收到用户请求，调用dubbo服务，然后将结果返回给用户，整条链路只有一个traceId。开始于用户请求，结束于用户收到结果。
spanId 一个链路中每次请求都会有一个spanId。例如一次rpc，一次sql都会有一个单独的spanId从属于traceId。
cs Clent Sent 客户端发起请求的时间，比如 dubbo 调用端开始执行远程调用之前。
cr Client Receive 客户端收到处理完请求的时间。
ss Server Receive 服务端处理完逻辑的时间。
sr Server Receive 服务端收到调用端请求的时间。
sr - cs = 请求在网络上的耗时 ss - sr = 服务端处理请求的耗时 cr - ss = 回应在网络上的耗时 cr - cs = 一次调用的整体耗时
Zipkin的工作过程 当用户发起一次调用时，Zipkin 的客户端会在入口处为整条调用链路生成一个全局唯一的 trace id，并为这条链路中的每一次分布式调用生成一个 span id。span 与 span 之间可以有父子嵌套关系，代表分布式调用中的上下游关系。span 和 span 之间可以是兄弟关系，代表当前调用下的两次子调用。一个 trace 由一组 span 组成，可以看成是由 trace 为根节点，span 为若干个子节点的一棵树。
Zipkin 会将 trace 相关的信息在调用链路上传递，并在每个调用边界结束时异步的把当前调用的耗时信息上报给 Zipkin Server。Zipkin Server 在收到 trace 信息后，将其存储起来。随后 Zipkin 的 Web UI 会通过 API 访问的方式从存储中将 trace 信息提取出来分析并展示。

安装Docker CentOS 7 (使用yum进行安装)
step 1: 安装必要的一些系统工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
Step 2: 添加软件源信息
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo cat /etc/yum.repos.d/centos.repo[centos7] name='centos' baseurl='http://mirror.centos.org/centos/7/os/x86_64/' enabled=1 gpgcheck=0 [centos7-extra] name='centos extra' baseurl='http://mirror.centos.org/centos/7/extras/x86_64/' enabled=1 gpgcheck=0
Step 3: 更新并安装Docker-CE
sudo yum makecache fast sudo yum list docker-ce --showduplicates | sort -r sudo yum -y install pigz container-selinux sudo yum -y install docker-ce
Step 4: 开启Docker服务
sudo systemctl start docker docker run hello-world
docker-compose Compose 是用于定义和运行多容器 Docker 应用程序的工具。通过 Compose，您可以使用 YML 文件来配置应用程序需要的所有服务。然后，使用一个命令，就可以从 YML 文件配置中创建并启动所有服务。
curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s) -$(uname -m) " -o /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-composeln -s /usr/local/bin/docker-compose /usr/bin/docker-composedocker-compose --version

观察Zipkin Web 确认服务个数 再次刷新zipkin，即可看到service name发生变化
