I have created my website in node. where I am using different port for different modules.
like
http://localhost:5555/ this is for admin,
http://localhost:5050/ this is for client access.'
I am using Digitalocean Ubuntu server and I have bought domains from Godaddy.
I want to set different domain on different port.
like
http://localhost:5555/ should be "http://admin.example.com".
http://localhost:5050/ should be "http://example.com".
I have tried with nginx in Ubuntu but doesn't get any useful.
Please help me . Thanks in advance.
You need two server configs in your nginx config file, one for the admin subdomain and one for example.com itself. It should look something like this:
server {
listen 80 default;
server_name example.com .example.com ;
location / {
proxy_pass http://localhost:5050;
proxy_pass_header Server;
proxy_redirect off;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $remote_addr;
}
and
server {
listen 80;
server_name admin.example.com;
location / {
proxy_pass http://localhost:5555;
proxy_pass_header Server;
proxy_redirect off;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $remote_addr;
}
}

I'm serving multiple nodejs apps on a single server through pm2 and using nginx to manage reverse proxies. Right now if I use the server's ip and app port to reach the apps directly it all works fine. But if I try to navigate to my apps through the location paths set in the nginx config then I get 404 errors.
Below is my nginx default config:
upstream frontend {
server localhost:3000;
}
upstream backend {
server localhost:8000;
}
server {
listen 443 ssl;
server_name <redacted>;
ssl_certificate <redacted>.cer;
ssl_certificate_key <redacted>.key;
error page 497 301 =307 https://$host:$server_port$request_uri;
location /app/frontend {
proxy_pass http://frontend;
proxy_redirect off;
proxy_set_header Host $host:$server_port;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Ssl on;
}
location /api {
proxy pass http://backend;
proxy_redirect off;
proxy_set_header Host $host:$server_port;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Ssl on;
}
}
server {
listen 80;
server_name <redacted>;
return 301 https://$server_name$request_uri;
}
Now when I try to go to https://<server ip>:3000, the frontend loads just fine but if I go to https://<server ip>/app/frontend, I get the following 404 error:
Although the index.html loads up, it tries to find the static assets on https://<server ip>/ but rather should try to find them on https://<server ip>:3000. This is the exact behaviour that I'm trying to achieve.
What I have tried so far:
Using rewrites
Adding trailing slashes to both location path and proxy_pass
I know this can be solved by changing the app's base url or the build directory but that is not what I'm looking for.
Any help would be highly appreciated.
I have a digital ocean droplet running Ubuntu 18.04 and inside is is an lxc container. I have two applications in that container.
The first application (a client) lives at /var/www/html and the second one is the NodeJS application that lives at /var/www/my-site/. The Node application inside the container is managed by pm2 and everything seems to be working fine thus far because when I type in curl http://localhost:3000 at the container terminal, I get back the desired output.
Inside the main droplet (not the container) under /etc/nginx/sites-available, I have the following two server blocks - default and my-site.
The first app works fine when I try to access it through the browser via my domain but the NodeJS application returns a 502 Bad Gateway when I try to access it through sub.mydomain.com. pm2 start inside the container tells me that the node application status is online.
Here is my default server block file. This works. When I visit mydomain.com, my site shows up fine.
# HTTP — redirect all traffic to HTTPS
server {
listen 80;
listen [::]:80 default_server ipv6only=on;
return 301 https://$host$request_uri;
}
server {
# Enable HTTP/2
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name mydomain.com;
# Use the Let’s Encrypt certificates
ssl_certificate /etc/letsencrypt/live/mydomain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/mydomain.com/privkey.pem;
# Include the SSL configuration from cipherli.st
include snippets/ssl-params.conf;
root /var/www/html;
index index.html index.htm index.nginx-debian.html;
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://container_ip_address /;
}
}
Now here is the other server block - my-site.
# Upstream config
upstream site_upstream {
server 127.0.0.1:3000;
keepalive 64;
}
server {
# Enable HTTP/2
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name sub.mydomain.com www.sub.mydomain.com;
root /var/www/my-site;
# Use the Let’s Encrypt certificates
ssl_certificate /etc/letsencrypt/live/mydomain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/mydomain.com/privkey.pem;
# Include the SSL configuration from cipherli.st
include snippets/ssl-params.conf;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://site_upstream;
proxy_ssl_session_reuse off;
proxy_set_header Host $http_host;
proxy_cache_bypass $http_upgrade;
proxy_redirect off;
}
}
I have set the A Record for my subdomain on my domain's DNS settings, to my droplet's IP address and I have also created a symbolic link to /etc/nginx/sites-enabled for the my-site server block.
I have scoured the internet for a solution to this problem but nothing seems to be working. What am I missing?
Your help would be greatly appreciated. Thanks.
The problem here was that requests to the sub domain were not being directed to the lxc container.
I solved this by adding the following inside the my-site server block.
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://container_ip/;
}
After that I added an asterisk to the next location block.
location /* {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://site_upstream;
proxy_ssl_session_reuse off;
proxy_set_header Host $http_host;
proxy_cache_bypass $http_upgrade;
proxy_redirect off;
}
Another way of getting around this issue was by including the sub-domain in the server_name directive for the default server block. This worked but the only problem was that nginx would complain that it had to ignore the server I had set up in the my-site server block when you ran nginx -t, otherwise, it worked just fine.
I have a node.js app running on my AWS instance and I'm using NginX to serve it up.
I am trying to redirect the www.websitename.com traffic to websitename.com. I have tried setting up a redirect in the etc/nginx/sites-available/websitename file and it looks like this:
upstream app_websitename {
server 127.0.0.1:8000;
keepalaive 8;
}
server {
listen 0.0.0.0:80;
server_name www.websitename.com;
return 301 http://websitename.com$request_uri;
}
server {
listen 0.0.0.0:80;
server_name websitename.com;
access_log /var/log/nginx/websitename.log;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://app_websitename/;
proxy_redirect off;
}
}
Any ideas are appreciated. I have been trying stuff all over the place ;)
replace this listen 0.0.0.0:80; With
listen 80 ;
listen [::]:80;
Did you also add websitename.com to your host file ?
It ended up being a problem with the way the company I bought the domain name from not saving my A-record properly. I spent a whole day wondering what I did wrong lol.
I am running Glassfish 3.1.2 on Linux 6 server to deploy Oracle Apex.
I want to to hide port 8383 from url (current url say : https://sd1.domain.com:8383/apex)
80 and 443 port are already assigned for another service.
So, how can I hide port 8383 from URL.
A TCP connection is between two ip:port pairs. In case the server's port is a common one like 80/443, most browsers don't display it.
You can use a reverse proxy on port 80, that classifies incoming HTTP traffic.
It could check the subdomain in the HTTP header and then forward traffic to one of the two web servers (which both listen on dedicated ports).
With nginx the config file could look like this:
server {
server_name sd1.domain.com;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://localhost:8383;
}
}
server {
server_name www.domain.com;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://localhost:8080;
}
}
Have a Nginx box on the DMZ that is to proxy trough to a IIS box on the LAN.
I can get to the home page OK via the Nginx box however after navigating further it seems to re-direct rather than proxy.
Is there additional config needed either on the IIS or Nginx side?
server {
listen 80;
listen 443;
server_name internal.lan.com;
location / {
proxy_pass http://internal.lan.com;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_redirect off;
}
}
