利用MultiCore应用服务计划(Windows)实现Azure应用服务中的NodeJs

Question

我创建了一个nodeJs应用程序，并使用Azure (VSTS)将其部署到Azure AppService。

我必须指定运行Node应用程序的Web.config (其他明智的是，Azure AppService应用程序没有响应)。

下面可以看到Web.config文件。

问题是，我不知道配置是在multiCore机器上运行单个进程还是多个进程？

至少我还没有在微软网站的文档中看到这一点。

如何指示Azure AppService使用所有核心？

我知道pm2 npm模块，它可以使用，事实上我正在本地机器上使用它。

但我该怎么告诉Azure用它呢？

如何告诉Web.config使用pm2

有一个关于AppService的最佳实践的文档，但是它指示只在基于Linux的应用程序服务计划而不是Windows中使用pm2。

      You can control how Node is hosted within IIS using the following options:
        * watchedFiles: semi-colon separated list of files that will be watched for changes to restart the server
        * node_env: will be propagated to node as NODE_ENV environment variable
        * debuggingEnabled - controls whether the built-in debugger is enabled

查看您的web.config文件：

<!--

<!--<iisnode watchedFiles="web.config;*.js"/>-->

如果按照此处提供的链接进行操作，您将看到可以设置以下内容：

• nodeProcessCountPerApplication - IIS将在每个应用程序中启动的node.exe进程数；将此值设置为0将导致在机器上每个处理器创建一个node.exe进程。

所以：

<iisnode nodeProcessCountPerApplication="0"/>
