Run script at boot/startup in Ubuntu 12.04 x64 Server

Question

I am trying to start the RoR application named fedena.

What I generally do is SSH login as rootand hit these commands

root@cloud:~# cd fedena
root@cloud:~/fedena# script/server
=> Booting WEBrick
=> Rails 2.3.5 application starting on http://0.0.0.0:7800
and so on...meaning the app server is running

Then when I close the SSH session, the application ends.

Now,what I figured out was for keeping it alive was to run this shell script through webmin interface and it survived. But, I wanted to autorun this script on every boot/restart. I tried to add

./fedena/script/server

before the exit 0 line in the

/etc/rc.local

Alas ! It didn't work. Why I don't understand.

Answer 1

Given your script is bash and the path is /root/fedina/server/script you could have:

##!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

bash /root/fedina/server/script

exit 0

Note: Don't forget about the execution bits (eg. chmod a+x /etc/rc.local)
