A problem with Chromium kiosk

I have run a dietpi 2 years headless as a file server on an intel nuc. Recently I want to make more use of the machine and installed a chromium through dietpi-software.But the problem is:
I still run the machine headless most of time so I need to run the chromium manually just as other desktop environment.
obviously [startx] won’t work.I searched the Internet and tried [chromium-kiosk] which still didn’t work.
Is there any command can start the chromium manually just like the [startx]?
Thanks for any suggestion.

you could set Chromium to autostart and reboot your system. Or if you don’t want to reboot, execute the following:


This should start Chromium
