what have you tried exactly? you can add start scripts in the rcX.d dirs.

Hi Pan64,

I tried to add that script in rcX.d but it dont works. I wanted to run that command script on specific directory (i.e. /home/rails/www.abc.com/" with user RAILS.

Hi Pan64,

Please find the command script as below:

Quote:

#!/bin/sh

bundle exec unicorn -l 3030 -E production -D

I have named this script as start.sh and i am running this script in my Documentroot os the site lets say in "/var/www/www.abc.com" directory by switching with the user RAILS.

where did you put that start.sh? how did you set the permissions?

mahi_nix · 06-19-2014, 02:59 AM

I have kept that scirpt in "/var/www/www.abc.com" directory, and the permission on script is 775.

I am starting this script by following below steps:

1) su - rails
2) cd /var/www/www.abc.com
3) ./start.sh

This way i am manually starting this script.

now i wanted to start this automatically at the boot time.

. How did you try it?

I added that script in /etc/init.d/ and then created symlink in rcX.d (i.e S20rubustart) and then reboot server to test it.

probably S99 would be better.
you need to combine all the steps in #7 into one single script I think.
that will look like:

Code:

cd /var/www/www.abc.com
/usr/bin/sudo -u rails /full/path/to/bundle exec unicorn -l 3030 -E production -D

Hi,

I tried solution suggested by you but it didnt worked. Please find the error as below.

Code:

root@localhost:~# ./start.sh
Gemfile syntax error:
/var/www/www.abc.com/Gemfile:36: syntax error, unexpected ':', expecting $end
gem 'xcases', git: 'ssh://user1@git.gitserv.com/var/lib/git/xcases.git'

I executed this script using root user login.

Please suggest.

I can only execute the start.sh script in "/var/www/www.abc.com" directory with rails user. script does not work with any other user and on any other location on server.

You can use /etc/rc.local, by adding the sequence of the commands above as follows:

Code:

su - rails -c "/var/www/www.abc.com/start.sh"

What exactly is not working? The command or the startup method (/etc/rc.local)?
