Skywalking-9.6.0系列之本地源码编译并启动

c_zyer2023-08-15 11:17

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：

执行以下命令，来获取这些代码数据：

bash 复制代码 
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 复制代码 
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

  1. 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

  2. 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 复制代码 
        <arguments>install --registry=https://registry.npmjs.org/</arguments>
     <!--修改为淘宝镜像-->
    <arguments>install --registry=https://registry.npm.taobao.org/</arguments>

  3. 【qiang】的问题，以为会变快，其实反作用

  4. 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
xml 复制代码

    superDatasetIndexShardsFactor: ${SW_STORAGE_ES_SUPER_DATASET_INDEX_SHARDS_FACTOR:5} #  This factor provides more shards for the super data set, shards number = indexShardsNumber * superDatasetIndexShardsFactor. Also, this factor effects Zipkin traces.

    advanced: ${SW_STORAGE_ES_ADVANCED:""}
    # Enable shard metrics and records indices into multi-physical indices, one index template per metric/meter aggregation function or record.
    logicSharding: ${SW_STORAGE_ES_LOGIC_SHARDING:false}
    # Custom routing can reduce the impact of searches. Instead of having to fan out a search request to all the shards in an index, the request can be sent to just the shard that matches the specific routing value (or values).
    enableCustomRouting: ${SW_STORAGE_ES_ENABLE_CUSTOM_ROUTING:false}

    asyncBatchPersistentPoolSize: ${SW_STORAGE_ASYNC_BATCH_PERSISTENT_POOL_SIZE:1}
  • 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

以上源码构建，本地部署Skywalking项目就算告一段落啦
