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.

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
