Start or Stop a script on Boot and Shutdown

Run a script when the system starts up or reboots on Ubuntu.

1) Create script, on this example I'm starting the gluu-server service as the root user

$sudo nano /etc/init.d/MyScriptName

Copy/paste the following script, update accordingly:

# /etc/init.d/MyScriptName
#

case "$1" in
  start)
    echo "Attempting to Start Gluu Server..."
    sudo -H -b service gluu-server start
    ;;
  stop)
    echo "Attempting to Stop Gluu Server..."
    sudo -H service gluu-server stop
    ;;
  *)

esac

exit 0

2) Give the script executable permission

$sudo chmod +x /etc/init.d/MyScriptName

3) Tell script to run at startup. This tells the script be the first to shutdown and the last to…

Advanced Drupal Caching using Varnish over HTTPS

There are many sites that offer lots of static content through HTTPS that can definitely be cached using Varnish and in order to do so we need to implement an extra layer before any request goes to our Varnish Server. This layer is going to be handled by a Load Balancer/Proxy Server which will take care of routing the HTTP and the HTTPS requests, by interpreting SSL and converting the…
