Sample service script for init

This script enables fast daemonization apps as a Linux services with SysVinit init system.

Look at LSB init scripts for more information.

Original script taken from from naholyr's gist Note: You can acheive the same thing that this project tries to acheive by using the MetaInit package in debian: (https://wiki.debian.org/MetaInit)

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

For rpm based distributions such as CentOS or Red Hat, you can use

$ chkconfig $YOUR_SERVICE_NAME --add

If you want to see which runlevel your script will run in

$ chkconfig $YOUR_SERVICE_NAME --list

Enjoy

Uninstall

The service can uninstall itself with service $NAME uninstall. Yes, that's very easy, therefore a bit dangerous. But as it's an auto-generated script, you can bring it back very easily. I use it for tests and often install/uninstall, that's why I've put that here.

Don't want it? Remove lines 56-58 of the service's script.

Logs?

Your service will log its output to /var/log/$NAME.log. Don't forget to setup a logrotate :)

FAQ!

This script should work fine on Debian, CentOS and Slackware.

I'm noob and/or lazy

Yep, I'm lazy too. But still, I've written a script to automate this :)

$ wget 'https://raw.githubusercontent.com/Navneet-Suresh/sysvinit-service-generator/master/new-service.sh' && bash new-service.sh

In this script I will download service.sh into a tempfile, replace some tokens, and then show you commands you should run as superuser.

If you feel confident enough with my script, you can sudo the script directly:

$ wget 'https://raw.githubusercontent.com/Navneet-Suresh/sysvinit-service-generator/master/new-service.sh' && sudo bash new-service.sh

Note: the cool hipsterish curl $URL | bash won't work here, I don't really want to check why.

The script works offline so you can clone this repository then you can upload this script on your server and run it directly:

$ sudo bash new-service.sh

The script also handle parameters as showed below:

$ sudo bash new-service.sh "service_name" "description" "command to execute" "user which executes the command"
