Create Init.d Script

Sample service script for debian/ubuntu

Look at LSB init scripts for more information.

Usage

Copy service.sh to /etc/init.d:

# replace "$YOUR_SERVICE_NAME" with your service's name
cp "service.sh" "/etc/init.d/$YOUR_SERVICE_NAME"
chmod +x /etc/init.d/$YOUR_SERVICE_NAME
chown root /etc/init.d/$YOUR_SERVICE_NAME
chgrp root /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)

Test the service

service $YOUR_SERVICE_NAME start
service $YOUR_SERVICE_NAME stop

Run at boot-time

update-rc.d $YOUR_SERVICE_NAME defaults

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 :)

Problems

unable to execute /etc/init.d/$YOUR_SERVICE_NAME: No such file or directory.

Maybe it has been modified by a Windows's editor and the line endings could be not corrected. This can be verified with the command cat -v service.sh and verifying that there are some strange characters as ^M.

To fix that:

sed -i 's/\r//g' service.sh

Failed to start xxx.service: Unit xxx.service not found.

to fix that:

sudo systemctl enable xxx

auto create new service

Using new_service.sh to auto create new service.
