使用pm2将环境变量传递给node.js [英] Passing environment variables to node.js using pm2

问题描述

我试图将一些参数传递给由pm2运行的Express应用程序.他们的文档中没有任何提示，但显然可以将某些EV传递给您的节点应用程序，例如SOME_STUFF=xxx pm2 start app.js.

I am trying to pass some arguments to my Express application which is run by pm2. There wasn't any hint in their documentation to do so, but apparently it's possible to pass some EV to your node application like SOME_STUFF=xxx pm2 start app.js.

推荐答案

实际上是有可能的，我很确定它早在PM2的文档中.

It's actually possible and I'm pretty sure it was in PM2's documentation some time ago.

无论如何，这就是您需要做的:

Anyways, that's what you need to do:

pm2 start app.js -- -some_stuff xxx

基本上，添加--，然后您可以添加自己的应用程序参数.

Basically, add -- and then you can add your own app parameters.

设法找到源，它被很好地隐藏了: http://pm2.keymetrics.io/docs/usage/quick-start/#42-ways-of-starting-processes

Managed to find the source, it was hidden quite well: http://pm2.keymetrics.io/docs/usage/quick-start/#42-ways-of-starting-processes
