Sample /etc/init.d script
Raw
service.md

Sample service script for debianoids

Look at LSB init scripts for more information.

Usage

Copy to /etc/init.d:

# replace "$YOUR_SERVICE_NAME" with your service's name (whenever it's not enough obvious)
cp "service.sh" "/etc/init.d/$YOUR_SERVICE_NAME"
chmod +x /etc/init.d/$YOUR_SERVICE_NAME

Edit the script and replace following tokens:

  • <NAME> = $YOUR_SERVICE_NAME
  • <DESCRIPTION> = Describe your service here (be concise)
  • Feel free to modify the LSB header, I've made default choices you may not agree with
  • <COMMAND> = Command to start your server (for example /home/myuser/.dropbox-dist/dropboxd)
  • <USER> = Login of the system user the script should be run as (for example myuser)

Start and test your service:

service $YOUR_SERVICE_NAME start
service $YOUR_SERVICE_NAME stop

Install service to be run at boot-time:

update-rc.d $YOUR_SERVICE_NAME defaults

Enjoy

I'm noob and/or lazy

Yep, I'm lazy too.

I may edit the gist and provide an automated way to install new services.
