Where do log files locate in pm2 in sudo mode

Question

I'm new to PM2 and ubuntu-related issues.

I'm running an app using sudo with the syntax sudo pm2 start app.js --time.

However, when I tried to check the files in $HOME/.pm2/logs/app-error.log, I couldn't find any logs related to what I logged in the code. I believe sudo pm2 start is different from pm2 start, and the log files are only for the pm2 start.

My question is, how can I check the logs in sudo pm2?

Have you checked `/root/.pm2/logs/`? Which makes sense, seeing that `sudo` executes a command as the root user. — snwflk, Aug 14 '22 at 11:09
I've accessed it and the only folder in root was the snap folder. — Lucas.Pheliny, Aug 14 '22 at 11:15
How did you check? Did you happen to simply `ls`? You need the `-a` to show entries starting with a dot. I.e. `ls -a` to show all dir entries. — snwflk, Aug 14 '22 at 11:19
Hi, I forgot to check all the hidden files. I can see all the logs in pm2 folder now :D — Lucas.Pheliny, Aug 14 '22 at 11:26

If you execute pm2 as the root user, the logs will be stored in /root/.pm2/logs/.

sudo executes commands as the root user, and that also entails that the home directory (referred to as $HOME or ~) that the command sees is the root user's home directory, which usually is /root.

So, if a program writes logs to the user's home directory, the location of the log files will depend on what user is executing that program.

By default, pm2 will store log files in ~/.pm2/logs.

Yes, I know about it. But the data stored by `sudo pm2` and `pm2` are two different data. And I don't know where to find those data from `sudo pm2` – Lucas.Pheliny Aug 14 '22 at 11:07

You can change the logs location like this:

Generate an ecosystem file:

pm2 ecosystem simple

Then edit the ecosystem file and add lines for changing the default location:

module.exports = {
  apps : [{
    name   : "My Application",
    script : "./myapp.js",
    error_file : "/var/log/pm2/myapp/err.log",
    out_file : "/var/log/pm2/myapp/out.log"
  }]
}

Alternatively, you can also use the command line:

pm2 start -n "My application" -o /var/log/pm2/myapp/out.log -e /var/log/pm2/myapp/err.log /path/to/my/application

I believe it's in /root/.pm2/logs/. Probably you haven't check them all using ls -a
