前言

       Zipkin Server預設儲存追蹤資料至記憶體中，這種方式並不適合生產環境，一旦server關閉重啟或者服務崩潰，就會導致歷史資料消失。Zipkin支援修改儲存策略使用其他儲存元件，支援MySQL，Elasticsearch等。

1、資料庫指令碼

（將鏈路追蹤資料儲存到MySQL中，實現同步處理）
 
開啟MySQL資料庫，建立zipkin庫，執行一下SQL指令碼。

把以上程式碼轉存成sql檔案
 

3、部署Zipkin服務端

新增啟動引數，重新部署服務端

官網地址：https://github.com/openzipkin/zipkin/blob/master/zipkin-server/src/main/resources/zipkin-server-shared.yml

java -jar zipkin-server-2.20.1-exec.jar --STORAGE_TYPE=mysql --MYSQL_HOST=localhost --MYSQL_TCP_PORT=3306 --MYSQL_USER=root --MYSQL_PASS=root --MYSQL_DB=zipkin
 

4、測試

訪問：http://localhost:9000/order-service/order/1 檢視資料庫結果如下：
