Skywalking相信有很多人使用过,通过容器或者下载安装包进行安装的,今天从源代码角度,拉取、构建、启动。
官方文档步骤简洁明了,我这边会结合自己遇到的一些问题做出总结。
当前构建资源版本:
- MAC 10.15.7
- IDEA 2021.2
- node v16.14.0 (据代码要求安装了一个新版本)
- npm 8.3.1
- Skywalking 9.6.0-SNAPSHOT
- JDK 11 (最新的代码要看最新的要求,注意不能使用JDK8,用错的话构建时也会有提示)
- Maven 3.6.0
官方指南(必看):https://github.com/apache/skywalking/blob/master/docs/en/guides/How-to-build.md
快速阅览
流程1:源码获取
方法一:fork代码后,在自己的仓库下 git clone源代码
方法二:下载源码包后解压
【下载失败,网络问题,只能自行解决】
流程2:submodule模块初始化
.gitsubmodules文件
[submodule "apm-protocol/apm-network/src/main/proto"]
path = apm-protocol/apm-network/src/main/proto
url = https://github.com/apache/skywalking-data-collect-protocol.git
[submodule "oap-server/server-query-plugin/query-graphql-plugin/src/main/resources/query-protocol"]
path = oap-server/server-query-plugin/query-graphql-plugin/src/main/resources/query-protocol
url = https://github.com/apache/skywalking-query-protocol.git
[submodule "test/e2e-v2/java-test-service/e2e-protocol/src/main/proto"]
path = test/e2e-v2/java-test-service/e2e-protocol/src/main/proto
url = https://github.com/apache/skywalking-data-collect-protocol.git
[submodule "skywalking-ui"]
path = skywalking-ui
url = https://github.com/apache/skywalking-booster-ui.git
以上可以看出关联的仓库数据主要有:
- https://github.com/apache/skywalking-data-collect-protocol.git
- https://github.com/apache/skywalking-query-protocol.git
- https://github.com/apache/skywalking-data-collect-protocol.git
- https://github.com/apache/skywalking-booster-ui.git
执行以下命令,来获取这些代码数据:
bash
git submodule init //初始化仓库目录位置
git submodule update //**这步骤至关重要**
这个环节由于涉及四个仓库的代码拉取,此时如果网络状况不佳,很有可能存在【空文件夹】的情况,所以可以这样解决:
方法一 :保障网络稳定,删除拉取的空文件夹,再重新git submodule init
AND git submodule update
,重复尝试直至拉取成功
关注这些项目文件夹:
- apm-protocol/apm-network/src/main/proto
- oap-server/server-query-plugin/query-graphql-plugin/src/main/resources/query-protocol
- test/e2e-v2/java-test-service/e2e-protocol/src/main/proto
- skywalking-ui
方法二: 去除.gitsubmodules文件中的内容,按照需求取拉取对应的代码,参照【gitsubmodules】文件目录要求放到指定的文件夹内
以上,可能存在的问题主要就是网络方面,如果以上项目目录未拉全就去执行下一步构建,会产生很多报错,这步必须确认好
或者流程1&2:二合一
bash
git clone --recurse-submodules https://github.com/apache/skywalking.git
也就是clone代码,并且把submodules一起拉下来
流程3:构建项目
前提确认一下JDK 11+ & Maven 3.6+ 的环境,最好提前安装node要求的版本
项目根目录下执行./mvnw clean package -Dmaven.test.skip
,构建项目较多,可能需要几分钟时间
这个步骤遇到比较多的问题,基本都是卡在node版本的下载和npm依赖包的拉取上,最终skywalking-ui的项目始终build不成功
-
node版本的下载,本地有8和18的版本,当前构建需要16的版本,下载网速出了问题
当前用到的v16.14.0,还可以确认一下node和npm的版本映射关系(https://nodejs.org/zh-cn/download/releases),我当前在npm8.3.1,是可以兼容
-
npm install拉取依赖包也存在网速问题,可以替换镜像源
skywalking/apm-webapp/pom.xml 中,找到
xml<arguments>install --registry=https://registry.npmjs.org/</arguments> <!--修改为淘宝镜像--> <arguments>install --registry=https://registry.npm.taobao.org/</arguments>
-
【qiang】的问题,以为会变快,其实反作用
-
整体流程构建如果最终都是卡在skywalking-ui前端项目的构建上,可以单独使用对应的node版本去这个项目下单独
npm install
&npm run build
确认下,避免要重头再来,时间比较长
最终:

流程4:构建产生的源代码数据加入项目索引
IDEA中,可以找到对应的目录,右键 "Mark Dictory as" -> "Generated Sources Root",将构建产生的数据加入编辑器的索引中
- apm-protocol/apm-network/target/generated-sources/protobuf
- oap-server/server-core/target/generated-sources/protobuf
- oap-server/server-receiver-plugin/receiver-proto/target/generated-sources/fbs
- oap-server/server-receiver-plugin/receiver-proto/target/generated-sources/protobuf
- oap-server/exporter/target/generated-sources/protobuf
- oap-server/server-configuration/grpc-configuration-sync/target/generated-sources/protobuf
- oap-server/server-alarm-plugin/target/generated-sources/protobuf
- oap-server/oal-grammar/target/generated-sources
流程5:启动前后端代码
1.启动OAP核心服务,接收数据上报与数据查询
- /skywalking/oap-server/server-starter/src/main/java/org/apache/skywalking/oap/server/starter/OAPServerStartUp.java
- 后端项目启动,存储的数据默认是H2,也可以自己根据标准版本部署对应的elastcisearch版本进行配置
- 由于整体是插件化的架构风格,在组件的选择上使用
selector
即可快速锁定选择的组件。默认存储是h2,修改为es的只要selector: ${SW_STORAGE:elasticsearch}
并修改下方elasticsearch对应的配置即可

- 启动后端服务跑在 127.0.0.1:11800
2.启动web页面项目,供页面操作
- /skywalking/apm-webapp/src/main/java/org/apache/skywalking/oap/server/webapp/ApplicationStartUp.java
- 启动服务跑在 127.0.0.1:8080
- 浏览器中访问,可以展示菜单页
3.选择一个springBoot项目
- 可以选择下载skywalking-agent.jar,或者也走源码构建的流程
- 下载地址:https://skywalking.apache.org/downloads/#JavaAgent
- 页面选择Java Agent,可以选择源码包构建,或者打包好的distribution的包
- 这边直接下载打包好的包:https://www.apache.org/dyn/closer.cgi/skywalking/java-agent/8.16.0/apache-skywalking-java-agent-8.16.0.tgz
- 在springboot启动参数中添加skywalking追踪:-javaagent:~/Downloads/skywalking-agent/skywalking-agent.jar -Dskywalking.agent.service_name=demo -Dskywalking.collector.backend_service=127.0.0.1:11800
- 应用启动后能够查看到DB\REDIS相关的链接请求,访问后端服务接口,几秒后页面能够刷新报表。关注service,instance,endpoint相关指标
以上源码构建,本地部署Skywalking项目就算告一段落啦
