强制 PM2 从应用程序内重新启动 - 如何从正在运行的应用程序与 PM2 交互？

Question

I'm using PM2 to run a NodeJS app. Sometimes it's desirable to restart the app. Is there a way to do this from within the app, to avoid having to log into the server each time?

Would the simplest solution be to set PM2 to restart on changes in the app directory, then have the app touch a file? Or is there a way to interact with PM2 from within the app?

Answer 1

PM2 starts a process that ended, this means that if the process exits due to exception or natural exit, it will restart it.

So, just run this when ever need

process.exit(0)
