What is the difference between pm2 restart and pm2 reload

I have a nodejs app running on server.

When should I use pm2 restart,and when should pm2 reload be used?

Referred to the pm2 documention here,but couldn't figure out the difference in use case of the two.

Solution

  • The difference is documented here:

    As opposed to restart, which kills and restarts the process, reload achieves a 0-second-downtime reload.

    The latter means (found here):

    With reload, pm2 restarts all processes one by one, always keeping at least one process running.

    It also states that:

    If the reload system hasn’t managed to reload your application, a timeout will fallback to a classic restart.
