I have a Digitalocean VPS and 3 Nodejs (ExpressJs) application. Now I started all of them in same IP and different port like this:
- 95.5.5.8:65001
- 95.5.5.8:65002
- 95.5.5.8:65003
But now I want when anybody writes app1.com, the first app 95.5.5.8:65000 shows to him like this:
app1.com -> load server in port 65001
app2.com -> load server in port 65002
app3.com -> load server in port 65003
All of the applications are in same VPS by the same IP, How can I do this, please?
You can implement this feature by following steps:
In domain setting page, map app1.com, app2.com and app3.com to 95.5.5.8.
In Nginx, configure 3 proxies for app1.com, app2.com and app3.com in directory /etc/nginx/conf.d/. Here is the proxy file /etc/nginx/conf.d/app1.conf for app1.com:
server {
listen 80;
server_name app1.com;
access_log /var/log/nginx/app1_access.log;
charset utf-8;
location / {
proxy_pass http://95.5.5.8:65001;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded_For $proxy_add_x_forwarded_for;
}
}
Restart Nginx.

I am using Nginx as a load balancer. It is able to route the request to the designated host address, but not the port as mentioned in the upstream block. It always sends it to the default port.
I have tried a number of approaches modifing proxy_set_header Host, proxy_set_header X-Forwarded-For, proxy_set_header X-Real-IP, proxy_set_header X-Forwarded-Proto, proxy_set_header Referer etc. But nothing seems to work.
I have the Nginx server installed in Azure and trying to access VM's in the same virtual network.
Expected Behavior:
http://localhost/sites -----> http://zzz:9081/sites (should take IP:Port into acount)
Actual Behavior:
http://localhost/sites -----> http://zzz/sites (takes IP, but the port is 80/ default listen port).
upstream alb {
ip_hash;
server zzz:9081;
server zzz:9080;
}
server {
listen 80;
server_name localhost;
# root /usr/share/nginx/html;
location /sites {
proxy_pass http://alb/sites;
proxy_set_header X-Real-IP $remote_addr;
}
}
Any help will be greatly appreciated.
I have a node.js app and I am running nginx as a reverse proxy server. I want to access the same app through multiple ways.
Let the ip address of machine be 12.16.12.113.
Then I want the same app to be accessible through:
12.16.12.113:3000
test.example.com
I have 2 Configuration files for nginx in sites-available directory:
file1:
server {
listen 80;
server_name test.example.com;
location / {
proxy_pass http://localhost:3000;
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;
}
}
file2:
server {
listen 3000;
server_name default_server;
location / {
proxy_pass http://localhost:3000;
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;
}
}
The problem is that if I link both the files in sites-enabled directory, then only the app is accessible only through 12.16.12.113:3000. If I remove file2, then it is accessible through test.example.com.
But I want both the methods to work.
Edit 1:
Based on suggestion from this answer, I did the following test:
It appears that nginx is not listening to port 80. Why is this happening?
The are few ways to achieve that.
You can make your Node app listen on 12.16.12.113:3000 instead of on localhost:3000 and then you will need nginx only for port 80.
You can make your Node app listen on localhost:3000 (but only on localhost) and then proxy 12.16.12.113:3000 and port 80 by nginx.
You can make your Node app listen on localhost:4000 or 0.0.0.0:4000 on any interface and use nginx to proxy requests to port 80 and 3000.
But you will not be able to make them both listen on the same port and the same interface without problems.
This is the only advice that could be given considering the fact that you didn't include any code example of how your Node app is binding to the ports, which would be the only relevant information here.
i’m new to the javascript world and im trying to publish online a small react app that i‘ve done for tests.
So, first i installed nodejs in my server that already has nginx. Then expressjs, configure it and made a nginx .conf file that uses proxy_reverse to access port 8080 (chosen for nodejs). When i access the server name of that .conf file, without the port, the page it’s shown correctly.
The problem is, if i access another server name configured in my server and add the 8080 port at the end, nginx shows me my nodejs app, even with a server name different from the one configured in proxy_reverse.
Is there any way to limit access to that specific port to one specific server name and return a error everywhere else?
My nginx conf file:
server {
listen 80;
server_name react.mydomain.com;
access_log /var/log/nginx/react.access.log;
error_log /var/log/nginx/react.error.log error;
location / {
proxy_pass https://localhost:8080;
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;
# Enables WS support
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_redirect off;
}
}
Thanks
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 have a few applications that are running localy in defferents ports, how can I configure NGINX server for forwarding request from port 80 to my application depends on income domain name. For example 2 local apps named 'app1' on port 8181 , and if request comes from http://app1.com - nginx forwards to http://localhost:8181
I've looked at nginx docs, I ask for your examples if someone did this.
Thanks
Assuming you want to create a reverse proxy, my method is to first configure the following reverse proxy settings in a new file called /etc/nginx/reverse-proxy.conf:
# Serve / from local http server.
# Just add the following to individual vhost configs:
# proxy_pass http://localhost:3001/;
proxy_pass_header Server;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_connect_timeout 10;
proxy_read_timeout 10;
Then, for each reverse proxy I'm configuring, I add an appropriately-named configuration file in /etc/nginx/sites-enabled with the following:
server {
server_name app1.com;
server_name www.app1.com;
location / {
include /etc/nginx/reverse-proxy.conf;
proxy_pass http://localhost:8181/;
}
}
You can create as many server blocks as you like and point them at different local (or even remote) application servers. You can also add location blocks to serve different URLs within the same domain statically, or from different local application servers.
(You can also just roll all the configuration into /etc/nginx/nginx.conf, but I find it easier to separate configuration out into multiple files.)
I managed to do this easily by following this tutorial.
Create a new file in /etc/nginx/conf.d/ called your-domain.com.conf and put this in it:
server {
listen 80;
server_name your-domain.conf.com;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_pass http://127.0.0.1:2368;
}
}
Then restart nginx
sudo service nginx restart
