Can't hide location's port with nginx - node.js

Question

I'm trying to set up a domain for my node project with nginx (v1.5.11), i have succesfull redirected the domain to the web, but i need to use 3000 port, so now, my web location looks like http://www.myweb.com:3000/ and of course, i want to keep only "www.myweb.com" part like this: http://www.myweb.com/
I have search and try many configurations but no one seems to work for me, i dont know why, this is my local nginx.conf file, i want to change http://localhost:8000/ text to http://myName/ text, remember that the redirect is working, i only want to "hide" the port on the location.
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#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 8000;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
proxy_pass http://localhost:8000/;
proxy_redirect http://localhost:8000/ http://myName/;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
pd. I'm trying to fix it on my local windows 8 machine, but if other OS is required, my remote server works on Ubuntu 12.04 LTS
Thanks you all.

Answer 1

Add this to your server block:
port_in_redirect off;
E.g.
server {
listen 80;
server_name localhost;
port_in_redirect off;
}
Documentation reference.
You should also change server_name to myName. server_name should be your domain name.
You should also be listening on port 80, and then use proxy_pass to redirect to whatever is listening on port 8000.
The finished result should look like this:
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name www.myweb.com;
location / {
proxy_pass http://localhost:8000/;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}

Hiding the port during proxying needs these two lines in server body:
server_name_in_redirect off;
proxy_set_header Host $host:$server_port;
The conf is like:
server
{
listen 80;
server_name example.com;
server_name_in_redirect off;
proxy_set_header Host $host:$server_port;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://localhost:8080;
}
access_log off;
}
