Question

I want to automatically run a script when my Amazon server deploys. However, I keep getting the following error in my logs:

/root/start.sh: /usr/bin/bundle: /usr/bin/ruby: bad interpreter: No such file or directory

I’ve tried massaging my start script, but haven’t found a solution yet. I can load the god file manually, but when I start my machine, I get the following error. How do I set it up so that my bundler/ruby is detected when my script runs?

which ruby => /usr/local/rvm/rubies/ruby-1.9.3-p194/bin/ruby

This is my script that is supposed to autorun (start.sh)

cat /dev/null > /root/log
echo "Starting environment for $(whoami) at $(date)" >> /root/log

export RAILS_ENV=production
export RAILS_ROOT=/root/Rails3/www_rails
export QUEUE_NAME=place_matching

export HOME=/root
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function

cd /root/Rails3/www_rails
RAILS_ENV=production bundle exec god -c /root/Rails3/www_rails/god/resque_generic.god >> /root/log 2>&1
echo "Environment running at $(date)" >> /root/log

RVM provides documentation for your problem https://rvm.io/integration/god/

Additionally you could try this script:

cat /dev/null > /root/log
echo "Starting environment for $(whoami) at $(date)" >> /root/log

export RAILS_ENV=production
export RAILS_ROOT=/root/Rails3/www_rails
export QUEUE_NAME=place_matching

export HOME=/root

"$HOME/.rvm/bin/rvm" in $RAILS_ROOT do bundle exec god -c $RAILS_ROOT/god/resque_generic.god >> /root/log 2>&1
echo "Environment running at $(date)" >> /root/log

this is new notation of rvm which basically can be wrote down as:

rvm in /path/to/project do <command> ...

and is equivalent to what you were trying to do.

One more important thing, if you are running this as a different user thant the one owning RVM then your project .rvmrc requires to be trusted for that new user also. Alternatively you could use one of the new project files that do not require trusting:

• .ruby-version => 1.9.3@project
• Gemfile => #ruby=1.9.3@project / ruby="1.9.3"
• .versions.conf => ruby=1.9.3@project

Note that the second form also does bundler validation and does not allow patchlevel nor gemset name.
