Nodejs app doesn't run with pm2

Posted on September 7, 2019
Ubuntu 16.04 Node.js
Asked by Wanjohi

Hey, My Pm2 works fine but my web app won’t run. Then when I check the pm2 report, I get errored on status for both PM2 list and daemon logs. I am using pm2 version 3.2.2 and node version 8.0.0.

the code I run is pm2 start src/index.js and it is a react web app

How can I solve this?

Hello,

What are the exact errors that you get?

Also if you have not already checked the pm2 logs, I would recommend checking your pm2 logs with this command:

pm2 logs

If you are unsure, you could share the logs here so I could advise you further.

If there are no errors, then the problem might be with your application.

Also, as a side note here is also a quick video on how to deploy Node.js with PM2, Nginx as a reverse proxy, and Cloudflare for SSL termination:

In my situation, I also met pm2 errored:

internal/modules/cjs/loader.js:1068
  throw err;
  ^

Error: Cannot find module './config'

    '/usr/my/express/js/bin/www'
  ]
}
[nodemon] app crashed - waiting for file changes before starting...

As you can see above, I lost my ./config file, because I added it into .gitignore and when I cloned it on local machine, it lost.

Just retrieve the file back, and the problem solved!
