Hi there,

It sounds like that your nodejs user does not have access to the /root directory.

I’ve just tested running the project with the root user directly and it works well:

pm2 start app.js
[PM2] Applying action restartProcessId on app [app](ids: 0)
[PM2] [app](0) ✓
[PM2] Process successfully started

What you could do is:

  • Run pm2 as the root user
  • Alternatively, switch to the nodejs user, and git clone the project into the nodejs user’s home directory, that way the nmodejs user will be the owner of the files and would not have that permissions problem

Let me know how it goes!

Best,

Bobby

Hi @henriavo,

This sounds like a permissions/ownership issue. See if your have set some weird permissions most of all. Usually, and I believe the express app has the same permissions, they need to be 755 for folders nad 644 for files. You can do that for a faster outcome:

  1. find /path/to/express/app -f -exec chmod 644 {} \;

  2. find /path/to/express/app -d -exec chmod 755 {} \;

Where /path/to/express/app should be the real path.
