# zipkin安装 #

下载zipkin：curl -sSL [https://zipkin.io/quickstart.sh][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][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][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][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][20181219190858867.png]  
以上错误 参考 [http://www.cnblogs.com/sloveling/p/elasticsearch.html][http_www.cnblogs.com_sloveling_p_elasticsearch.html]

## elasticsearch head安装 ##

1.参考 [https://www.cnblogs.com/liuqi/p/6483317.html][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][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

      run `npm audit fix` to fix them, or `npm audit` for details

启动

[root@localhost elasticsearch-head]# npm run start
    > elasticsearch-head@0.0.0 start /home/zipkin/elasticsearch-head
    > grunt server
    
    >> Local Npm module "grunt-contrib-jasmine" not found. Is it installed?

    Waiting forever...
    Started connect web server on http://localhost:9100

## 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][https_github.com_wlmvp_zipkindemo]

## 运行结果 ##

### 发送一次调用请求 ###

### 在zipkin ui上的展示效果 ###
