X-Accel-Redirect + php not working - php

Question

Alright guys, I recently started messing with nginx and I need some help. I spent an entire day trying to figure this and I am simply done with it.
After I set the header in php for x-accel-redirect to work, I get an empty response. I am trying to serve image files from an external location to the website's root folder but in the same computer.
Can somebody point out what I'm doing wrong?
The funny/weird part is that I do not get any errors or warnings from nginx. I also do not get anything on the access/error logs, even with debug error logs turned on.
here is my nginx.conf
user Omi Admin;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log debug;
#error_log /usr/local/var/log/nginx/error.log debug;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
server {
listen 80;
server_name localhost;
#charset koi8-r;
location /unprocessed {
internal;
alias /usr/local/MyMateApp/ean_images/unprocessed;
}
root /Users/Omi/Desktop/CustomerServiceWebsite/www;
index index.html index.htm index.php;
error_page 404 /404.html;
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
try_files $uri = 404;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
include servers/*;
}
And here is where I set the header in php
header('X-Accel-Redirect: /unprocessed/' . $fileName);
I get a response back but it's simply empty.
