# PM2: `pm2 reload <app>` ignores edits to your ecosystem file — reload the file (and `script` changes need delete + start)

> Reloading by app name reuses the definition PM2 already holds, so changed env values are silently ignored. Reload the ecosystem file instead. Even that does not pick up a changed `script` path.

## Symptom
You change an environment value in `ecosystem.config.js`, run `pm2 reload myapp`, and the process still sees the old value.

## What happens (reproduced)
- `pm2 reload <app-name>` restarts the process with the definition PM2 already has in memory. A value changed in the file stayed at its old value.
- `pm2 reload ecosystem.config.js --only myapp` re-reads the file, and the new value arrived.
- Changing `script` (for example `a.js` → `b.js`) and reloading **by file** still ran the old `a.js`. A reload never changes the script path.

## Fix
- For config changes: `pm2 reload ecosystem.config.js --only <app>`, then confirm with `pm2 jlist` rather than trusting the exit code.
- For a changed `script`: `pm2 delete <app> && pm2 start ecosystem.config.js --only <app>`. This is a real restart, so expect a brief gap on single-instance apps.
- Run `pm2 save` afterwards, so the boot-time process list matches.
