一、安装zk和kafka
请参照：https://blog.csdn.net/h_sn9999/article/details/102622751
二、安装 elasticsearch
1、下载elasticsearch-5.5.0.zip
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.5.0.zip
2、解压
unzip elasticsearch-5.5.0.zip
3、移动到固定的目录
mv /elasticsearch-5.5.0 /usr/software/el
4、el属于开箱即用，进入目录
cd elasticsearch-5.5.0/bin ./elasticsearch
三、系统数据的处理流程
Zipkin 是一款开源的分布式实时数据追踪系统，其主要功能是聚集来自各个异构系统的实时监控数据，用来追踪微服务架构下的系统延时问题。Zipkin 的用户界面可以呈现一幅关联图表，以显示有多少被追踪的请求通过了每一层应用。在微服务架构中，一次用户请求可能会由后台若干个服务负责处理，那么每个处理请求的服务就可以理解为一个 Span，因此 Span 是一个树形结构，以体现服务之间的调用关系。Zipkin 的用户界面除了可以查看 Span 的依赖关系之外，还以瀑布图的形式显示了每个 Span 的耗时情况，可以一目了然的看到各个服务的性能状况。打开每个 Span，还有更详细的数据以键值对的形式呈现。
下图借用前辈画的
四、Zipkin Server
https://github.com/openzipkin/zipkin/releases
Running via Java:
curl -sSL https://zipkin.io/quickstart.sh | bash -s io.zipkin:zipkin-server:LATEST:slim zipkin.jar
java -jar zipkin.jarRunning via Docker:
docker run -d -p 9411:9411 openzipkin/zipkin-slimdownload jar： https://mvnrepository.com/artifact/io.zipkin.java/zipkin-server
java -DKAFKA_BOOTSTRAP_SERVERS=kafka001:9092 -DSTORAGE_TYPE=elasticsearch -DES_HOSTS=http://localhost:9300 -jar zipkin.jar
