On a EC2 with ubuntu 14.04 with nginx/passenger/rails came with this log on nginx:
App 31063 stderr: * ERROR *: Cannot execute /usr/local/lib/ruby: Permission denied (13)
App 31065 stderr: /etc/profile.d/rbenv.sh: line 3: rbenv: command not found
nginx conf is:
worker_processes 1; error_log logs/error.log; events { worker_connections 1024; } http { passenger_root /usr/local/lib/ruby/gems/2.2.0/gems/passenger-5.0.18; passenger_ruby /usr/local/lib/ruby; include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; server_name teste.com; root /home/ubuntu/teste/current/public; passenger_enabled on; rails_env production; access_log logs/access.log; location ~ ^/(assets)/ { gzip_static on; expires max; add_header Cache-Control public; } error_page 500 502 503 504 /500.html; client_max_body_size 4G; keepalive_timeout 10; } }  someone cloud give some light? thank's
