Where do log files locate in pm2 in sudo mode

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?

Solution

  • 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.
