問(wèn)題背景
上一篇文章使用了sleuth日志形式的鏈路追蹤决左，但微服務(wù)過(guò)多的時(shí)候，這種模式顯得非常臃腫無(wú)力，因此這個(gè)篇章使用zipkin可視化界面來(lái)查看追蹤鏈路
- 默認(rèn)已安裝JDK
- 可以根據(jù)前幾篇的文章和這篇這篇文章自己創(chuàng)建工程佛猛，也可以直接使用測(cè)試源碼
- zipkin服務(wù)端安裝包下載
- zipkin依賴是包含sleuth依賴的
- zipkin源碼官網(wǎng)文檔
Gateway+Nacos+Sleuth+Zipkin網(wǎng)關(guān)鏈路追蹤（測(cè)試及源碼）惑芭，Gateway+FeignClient+Nacos通過(guò)網(wǎng)關(guān)遠(yuǎn)程調(diào)用微服務(wù)（一）
Gateway+Nacos+Sleuth+Zipkin網(wǎng)關(guān)鏈路追蹤（測(cè)試及源碼），Gateway+Nacos+Sleuth鏈路追蹤（二）
Gateway+Nacos+Sleuth+Zipkin網(wǎng)關(guān)鏈路追蹤（測(cè)試及源碼）继找，Gateway+Nacos+Zipkin安裝部署可視化http方式鏈路追蹤（三）
Gateway+Nacos+Sleuth+Zipkin網(wǎng)關(guān)鏈路追蹤（測(cè)試及源碼）遂跟，Gateway+Nacos+Zipkin持久化mysql存儲(chǔ)rabbitmq消息隊(duì)列鏈路追蹤（四）
zipkin的下載安裝部署
1 前面幾篇文章講了nacos服務(wù)端的安裝，這篇文章講解一下zipkin的安裝码荔，zipkin有官方提供的jar包可以直接時(shí)候漩勤，本文作為測(cè)試工程就直接下載，沒(méi)有自己創(chuàng)建了
2 下載zipkin服務(wù)端缩搅，講一個(gè)通用的方法越败，以后大家也可以以這種方式下載
3 打開(kāi) https://search.maven.org/ 網(wǎng)站
4 在紅框中輸入需要查找的jar包，這里輸入zipkin-server
image
5 選擇紅框44所有版本
6 我選擇的是最新版本硼瓣，2.23.16版究飞，下載exec.jar版本才可以執(zhí)行，官網(wǎng)下載慢堂鲤，也可以下載我上傳的亿傅，在上文注意事項(xiàng)中
7 把java放入linux運(yùn)行，可以在本地運(yùn)行瘟栖，但前提都要有JDK環(huán)境葵擎，我個(gè)人把日志打印出來(lái)了
nohup java -jar zipkin-server-2.23.16-exec.jar >> zipkin.log &
8 默認(rèn)端口為9411，登錄http://127.0.0.1:9411/zipkin半哟，這里使用自己的IP即可
項(xiàng)目搭建
1 根據(jù)上一篇sleuth文章酬滤，更改sleuth的依賴為zipkin，zipkin依賴是包含sleuth依賴的

7 其他不用更改
測(cè)試步驟
1 啟動(dòng)nacos服務(wù)端体捏，zipkin服務(wù)端，gateway糯崎，service1几缭，service2
2 查看注冊(cè)中心http://localhost:8848/nacos，密碼和賬號(hào)都為：nacos
3 使用網(wǎng)關(guān)路由調(diào)用service1微服務(wù)API拇颅，service1微服務(wù)調(diào)用service2
4 查看zipkin奏司，點(diǎn)擊RUN QUERY，顯示調(diào)用鏈路
5 點(diǎn)擊紅框樟插，查看依賴鏈路
6 通過(guò)注冊(cè)中心使用微服務(wù)名顯示鏈路關(guān)系
心得
- 通過(guò)zipkin可視化界面看起來(lái)更清晰
- 這個(gè)篇章講的是http鏈路關(guān)系韵洋，此方式是同步的方式竿刁，微服務(wù)過(guò)多會(huì)產(chǎn)生一定延時(shí)，下個(gè)篇章介紹使用rabbitMQ的方式
作為程序員第 20 篇文章搪缨，每次寫(xiě)一句歌詞記錄一下食拜，看看人生有幾首歌的時(shí)間，wahahaha ...
