nginx doesn't redirect backend - node.js

I've nginx config that route frontend app to specific port, and backend to specific route
here's my configs
server {
listen 80;
server_name test.com www.test.com;
location / {
proxy_pass http://127.0.0.1:8080;
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;
proxy_redirect off;
}
location /api {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://127.0.0.1:3000;
proxy_set_header X-Real-IP $remote_addr;
}
}
when trying to access test.com directly it works, but when trying to access test.com/api , it doesn't work, then if return to main path test.com it also doesn't work, it seems like nginx stopped working after accessing the /api

removed "return 302 https://$host$request_uri;" from http block because it causes a ERR_TOO_MANY_REDIRECTS error
May I know what the issue is here? thank you.
Running a javascript application with node server
server {
listen 80;
# catch all server names here
server_name _;
return 301 https://$host$request_uri;
}
server {

server_name tite.rdc.nie.edu.sg;
location / {
proxy_pass http://localhost:8080/;

proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
Assumptions:
URL tite.rdc.nie.edu.sg running application branch A on server A
URL staging.tite.rdc.nie.edu.sg running application branch B on server A
Means that you can not run two different applications on same server behind same port. During application start-up you should get error message, something like:
Bind address already in use
Also check /etc/nginx/config folder if it does not contain another (defaults) *.conf files

Nginx not listening to ports

I am trying to set up a Nginx as a reverse proxy to access multiple NodeJS apps running on the same server.
I have my nodeJS apps running with PM2 and it all seems fine:
My nodeJS app is the simple nodeJS app generated with express-generator, so it is supposed to be running on port 3000.
I have also set up my Nginx with the following config
server {
listen 1004;
server_name pumadashboard.com;
location / {
proxy_pass http://127.0.0.1:3000;
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;
}
}
However when I curl 127.0.0.1:1004 I get a badGateway error from Nginx. I am also not able to access pumadashboard.com from anywhere on my local network, it just loads until timeout.
What do you get if you do:
curl http://locahost:3000
This should give back a response and like that you will understand if the application started properly.
This nginx configuration works for me
upstream pumadashboard.com {
server 127.0.0.1:3010;
}
server {
listen 80;
server_name pumadashboard.com;
root <path to your node application>;
access_log /var/log/nginx/your-access.access.log;
error_log /var/log/nginx/your-error.error.log;
add_header X-Frame-Options DENY;
add_header X-Content-Type-Options nosniff;
location / {
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_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_max_temp_file_size 0;
proxy_pass http://pumadashboard.com/;
proxy_redirect off;
proxy_read_timeout 240s;
}
}
Try adding
proxy_set_header X-Forwarded-Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Port 80;
to your location / block

Multiple websites in one VPS instance with NGINX

I still struggling with configuration of nginx for multiple websites in one virtual machine.
So If I do:
server {
listen 80;
server_name example1.com;
location / {
proxy_pass http://localhost:8181;
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;
}
}
after hit example1.com my nodejs page is loaded properly. But If I try to add second server block:
server {
listen 80;
server_name example2.com;
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;
}
}
Nothing is working, also example1. So I wanna to load through example2.com default nginx location... Something like that:
server {
listen 80;
server_name example1.com;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
}
server {
listen 80;
server_name example2.com;
location / {
proxy_pass http://localhost:8181;
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;
}
}
But it is always redirected to nginx root location.
How can I do that? Thanks for any help!
Node.JS?
You can refer my configuration:
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-Forwarded-Proto $scheme;
proxy_pass http://127.0.0.1:2368;
}
or another one
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_pass http://127.0.0.1:2387;
}
The first configuration direct to https redirect cycle.
And you said the default site, you can config something like that:
listen 80 default;
server_name xxxxx.com;

Subdomain alias in nginx and nodejs/express

I am trying to add a subdomain of my site. I have http://www.myweb.com/app/ and I just want http://app.myweb.com/ witch is the same of /app.
The content of /app is served by express in nodejs.
server {
listen 80;
server_name .myweb.com;
access_log /var/log/nginx/myweb.log;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://127.0.0.1:8888;
proxy_redirect off;
proxy_http_version 1.1;
}
}
And in nodejs I have:
http.use('/app', express.static(__dirname + '/static/app'));
But not sure if the statics should be served by nginx or nodejs/express
Searching in the web how use subdomain.
upstream your_app_name {
server localhost:3000;
keepalive 8;
}
server {
listen 80;
server_name ~^(?<sub>.+)\.domain\.com$;
location ~* \.html {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://your_app_name/$sub;
proxy_redirect off;
}
}
Sorry; my english its very bad

Nginx setup for local webapp and websocket

following is my nginx configuration,
server { //PART-1
listen 80;
server_name _;
location / {
proxy_pass http://127.0.0.1:8090;
proxy_redirect off;
proxy_pass_request_headers on;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection Upgrade;
}
}
server { //PART-2
listen 80;
server_name service;
root /usr/local/tomcat7/webapps/service-snapshot;
location / {
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8080/ServiceUI/;
}
}
first part of config works fine for websockets, which I am already using.
Second part of config is for webapp running on Apache tomcat 7.0.56, which is not working.
Is there something wrong with config? assuming server_name in both parts might be causing issue!
Any suggestions!
While having multiple services on one IP and port is working perfectly fine, the server_name directive is using the HOST header submitted by the client/browser. In this case, you're not supplying the header but instead asking for a specific location on the same server (you're not asking for http://_ or http://service but for http://yourserver/services from what I see in the comments).
To make it work, you have to specify the different services via locations like this:
server {
listen 80;
server_name THIS_IS_WHERE_YOUR_DOMAIN_OR_MAYBE_LOCALHOST_GOES;
location / {
proxy_pass http://127.0.0.1:8090;
proxy_redirect off;
proxy_pass_request_headers on;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection Upgrade;
}
location /Service {
root /usr/local/tomcat7/webapps/service-snapshot;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8080/ServiceUI/;
}
}
