全链路跟踪ZipKin学习实践_192.168.15.187:8081-优快云博客

本文链接：https://blog.youkuaiyun.com/wlmvp/article/details/85101069

本文介绍了如何安装和配置ZipKin，包括ZipKin服务器、Elasticsearch以及Elasticsearch Head。通过实例展示了SpringBoot应用中如何创建调用链，并解释了在ZipKin UI上查看调用链的效果。此外，还提供了详细的操作步骤和参考资料链接。

zipkin安装

下载zipkin：curl -sSL https://zipkin.io/quickstart.sh | bash -s
或者 wget -O zipkin.jar ‘https://search.maven.org/remote_content?g=io.zipkin.java&a=zipkin-server&v=LATEST&c=exec’

启动： java -jar zipkin.jar 默认使用内存存储模式
或者 java -jar zipkin.jar --STORAGE_TYPE=elasticsearch --DES_HOSTS=http://localhost:9200 指定elasticsearch做为数据存储

elasticsearch安装

参考 https://www.jianshu.com/p/85576c56700e

下载安装的压缩包
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.5.3.tar.gz
解压安装包
tar -xvf elasticsearch-6.5.3.tar.gz

修改conf下面的elasticsearch.yml

cluster.name: elasticsearch
node.name: master
path.data: /usr/local/elasticsearch-6.5.3/data
path.logs: /usr/local/elasticsearch-6.5.3/logs
network.host: 0.0.0.0
http.port: 9200

不能以root用户启动
创建elsearch用户组及elsearch用户

groupadd elsearch
useradd elsearch -g elsearch -p elasticsearch

启动
[elsearch@localhost bin]$ ./elasticsearch

在这里插入图片描述
以上错误参考 http://www.cnblogs.com/sloveling/p/elasticsearch.html

elasticsearch head安装

1.参考 https://www.cnblogs.com/liuqi/p/6483317.html 安装nodejs
2.
下载elasticsearch head代码
[root@localhost ~]# git clone https://github.com/mobz/elasticsearch-head.git
cd elasticsearch-head
执行 npm install

如果报错：npm ERR! Failed at the phantomjs-prebuilt@2.1.16 install script.
执行

[root@localhost elasticsearch-head]# npm install phantomjs-prebuilt@2.1.16 --ignore-scripts

启动

[root@localhost elasticsearch-head]# npm run start
> elasticsearch-head@0.0.0 start /home/zipkin/elasticsearch-head
> grunt server

测试调用程序

提供四个工程，分别对应四个服务分别是：springtest1，springtest2，springtest3，springtest4；springtest1通过httpclient调用springtest2，然后springtest2通过httpclient调用springtest3和springtest4，形成一个调用链；四个服务都是基于spring-boot来实现，对应的端口分别是8081，8082，8083，8084

具体代码见：https://github.com/wlmvp/zipkindemo

运行结果

发送一次调用请求
