Error during Capistrano deploy
When I run cap production deploy:start, Capistrano throws an error while starting the Unicorn server, however if I SSH into the server and run ./home/deployer/apps/<APPNAME>/current/config/unicorn_init.sh start, the server starts as it should (however, there is no output to say that the server has started in the terminal).
The error I get is the following:
INFO[fc27be26] Running /usr/bin/env /home/deployer/apps/explorelocal/current/config/unicorn_init.sh start on explore.jackhughesweb.com
DEBUG[fc27be26] Command: /home/deployer/apps/explorelocal/current/config/unicorn_init.sh start

I fixed my issue by adding the following to the top of my .bashrc:
export PATH="$PATH:$HOME/.rvm/bin"
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

Capistrano runs the non-login shell that has quite different environment from what a user has when he logs in via ssh. You can read more about it on this link from capistranorb.com.
When capistrano runs bundle something - it prepends every command with full path and all the necessary environment variables.
Here's the example command (it uses RBENV, but it's the same thing for rvm):
cd /var/www/webresume_qa/current &&
( RBENV_ROOT=~/.rbenv RBENV_VERSION=1.9.3-p429
~/.rbenv/bin/rbenv exec bundle exec
unicorn -D -c /var/www/webresume_qa/shared/config/unicorn.rb -E qa )
Unfortunately, since your unicorn_init.sh script doesn't have all this environment prepended before bundle exec unicorn it fails.
I've made a plugin capistrano-unicorn-nginx that tries to solve this problem. If you can't run the whole plugin, you might want to check just the specific solutions for unicorn_init.sh:
I know this is complicated, but I hope it helps.
