autostart express– location je //etc/systemd/system
vytvorim novy subor “sudo nano expres.service”
whereis node – zistim cestu k node
do ExecStart napisem cestu – napr: “node homeuser/flowserver/index.js” mozno treba aj sudo
spravime ho spustitelnym s “sudo chmod +x expres.service”
aby sa sam spustal dam “sudo systemctl enable expres”
ked uz je nahodou enablenuty treba ho reloadnut s “sudo systemctl daemon-reload”
ked nejde, treba dat pod ExecStart “WorkingDirectory = cesta/na/flowserver”

“sudo reboot” alebo “sudo systemctl reboot”
