How to restart server in production mode

Hi,

I started running vue-storefront in production mode.
I executed yarn start after yarn dev in vue-storefront directory
It all works fine.

And now I am going to change some part of my project.
how can I restart vsf?
how to stop running and restart it?

If you’re using yarn start - the pm2 is in use; so please use yarn pm2 reload all

Thank you very much.
It works well.
