Write your scrip and save

sudo x11vnc -ncache 10 -nap -forever -loop -repeat -rfbauth /home/user/.vnc/passwd -rfbport 5900 -noncache display :0 -noxdamage

Now everytime the OS boots it will run all scripts in the init.d

To test you can do the following

cd /etc/init.d
sudo ./x11vncscript.sh

ss -antp | grep vnc
/usr/share/novnc/utils/novnc_proxy --listen 8081 --vnc localhost:5900

You can access it now through your browser at http://10.10.10.102:8081/vnc.html?host=hostname&port=8081
