As you'll notice, I'm a bit of a noob on Rails. Here's the thing

I have a EC2 Bitnami RubyStack AMI running. I'm trying to deploy the sample project to be sure I'm doing the right thing, but I'm not getting anywhere at all. I just get a 503 error

I'm following bitnami's docs on thin + apache

Here are my files:

the httpd.conf I include in the main httpd.conf

Alias /sample "/home/bitnami/stack/projects/sample/public"
<Directory "/home/bitnami/stack/projects/sample/public">
  AllowOverride None
  Order allow,deny
  Allow from all
</Directory>

ProxyPass /sample balancer://appcluster
ProxyPassReverse /sample balancer://appcluster
<Proxy balancer://appcluster>
   BalancerMember http://127.0.0.1:3001/sample
   BalancerMember http://127.0.0.1:3002/sample
   BalancerMember http://127.0.0.1:3003/sample
   BalancerMember http://127.0.0.1:3004/sample
</Proxy>

the thin.yml file

chdir: /opt/bitnami/projects/sample
environment: production
address: 127.0.0.1
port: 3000
timeout: 30
log: log/thin.log
pid: tmp/pids/thin.pid
max_conns: 1024
max_persistent_conns: 512
require: []
wait: 30
servers: 5
prefix: /sample
daemonize: true

I'm able to start and stop apache, but thin does not stop correctly though. When I try to stop thin, I get this output

/opt/bitnami/projects/sample$ sudo thin -C config/thin.yml stop
Stopping server on 127.0.0.1:3000 ... 
Can't stop process, no PID found in tmp/pids/thin.3000.pid

Stopping server on 127.0.0.1:3004 ...

I've tried to use nginx as well, without any luck unfortunately.

Thank you for your time and help!
