nginx server routing issue (404) - nginx

Question

I'm using nginx to host multiple node applications. I am working on linking localhost:80 to the forever applications I have running.
I have multiple applications that initially work like below where I just go to each port:
____________ ___________
| | | my |
| localhost | -->| running |
| | | app(s) |
| (port #) | | |
|___________| |___________|
But since we have about 4 apps on different ports we want it to work like this:
____________ ___________ ____________
| | | | | my |
| nginx | -->| proxy |-->| running |
|localhost80| | pass | | app(s) |
|___________| |___________| |____________|
nginx should be routing to a page however I get "404 Not Found" which means the nginx is working but it has no idea what it's looking for.
Here is my code for one sample server application that I am trying to run:
Its a forever application (.js file) that is listening to a certain port.
#Server proxy for haiyan_dashboard
server {
listen 80; #
server_name localhost/haiyan;
location / {
proxy_pass http://localhost:8080/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
Also, here is my entire config file:
user nobody;
worker_processes 5;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

#access_log logs/access.log main;

}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#

location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80

proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
#Proxy for Haiti_Baseline

proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;

}
}
#ServerProxy for RFL Border
server {
listen 80; #is this also 3002???
server_name rfl_border;
location / {
proxy_pass http://localhost:3002/secure/; #Change the URL!!!
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
#ServerProxy for Basic Borders
server {
listen 80;
server_name basic_border;
location / {
proxy_pass http://localhost:9001/secure/; #This URL is Different
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 80;
# 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;
# }
#}
}
Am I using proxy pass properly? If not, how does it work in lamest terms. Additionally, ALL 4 pieces of server code sits in the nginx.conf file. Is this also a good practice.
(Note: I have already read the documentation on the nginx website)
If you need me to provide more clarification, I'll be happy to add it.
