How to install an init.d script in Ubuntu?

Reference link:

For example, to create a new script “vncserver”

sudo editor /etc/init.d/vncserver

Then enter the shell script (e.g., define start, stop, status, etc. check out one example inside that folder…).

Afterwards, make sure that you make the script executable after creation.

sudo chmod +x /etc/init.d/vncserver

Now insert the service into the start-up system so that it runs at boot

sudo insserv vncserver

Now, test to see if it works

sudo service vncserver start

To stop it

sudo service vncserver stop
