I have a node.js server running on port 5000 behind nginx and after reading several posts, I'm still getting a 502 from nginx. When accessing mydomain.com:5000 in a browser, everything works just fine. Can someone spot what I may be doing wrong here?
upstream backend {
server localhost:5000 max_fails=1 fail_timeout=3s;
keepalive 8;
}
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name mydomain.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl;

500 internal server error
when checked the nginx container logs this is the error that was showing.
rewrite or internal redirection cycle while internally redirecting to "/index.html", client: x.x.x.x, server: *.domain.com, request: "GET / HTTP/1.1", host: "master.domain.com
In location /auth when mentioned localhost keycloak cannot be reached when localhost is replaced with ip in nginx config it works fine.
Below is the nginx config file

I have a server where a node.js app is running
Now I want to run another app on the same server
I don't know what changes I should make to my nginx file
Please guide me
this is my nginx file
server {
listen 80;
server_name beranggrup.com , www.beranggrup.com;
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://localhost:3445;
proxy_redirect off;
proxy_buffering off;
}
location /images/ {
alias /opt/public/images/;
}
}
server {
listen 443 http2 ssl;
listen [::]:443 http2 ssl;
server_name beranggrup.com;
}
I am having a problem.
I have a node application running on :3000 on a subdomain inside of Plesk.
I have the subdomain https://xxx.flamingocams.co.uk ;
when I navigate to the subdomain it displays the default plesk page and this is the problem;
I have tried to change the port of the node application to 80 and 443 however this conflicts with plesk.
I have no issues when accessing the node application on https://xxx.flamingocams.co.uk:3000.
Now the only other thing I've seen other people attempt is a reverse proxy;
I found this example;
server {
listen 0.0.0.0:80;
server_name xxx.flamingocams.co.uk;
access_log "/var/log/nginx/xxxflam.log";
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_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_cache_bypass $http_upgrade;
}
}
I am running Plesk Obsidian v18.0.34_build1800210325.10 os_Ubuntu 16.04 so my question is, Where would I place this config to get the subdomain to point only to the nodejs application?
And is this config correct for what I'm trying to achieve?
I have little to no knowledge on nginx configuration my apologies
I have checked out this post and the answer says I need to add a config /etc/nginx/sites-available/yourdomain.com however I do not have the directory sites-available
response to comments // xxx.flamingocams.co.uk.conf
server {
listen 0.0.0.0:80;
server_name xxx.flamingocams.co.uk;

In your config, the server is running only on port 80
listen 0.0.0.0:80;
With this config, the page : http://xxx.flamingocams.co.uk will display your application (the request come to the NginX proxy then is forwarded to NodeJS application on port 3000). Because there aren't any server block listen on port 443, the default Plesk screen is displayed.
In order to have your app running on https, you need to listen on port 443 on NginX, you also need to configure the SSL certificate
The config would be :
server {
listen 0.0.0.0:443;
server_name xxx.flamingocams.co.uk;
ssl_certificate path_to_your_ssl_certificate;
ssl_certificate_key path_to_your_ssl_key;
# The rest of your config is ok :)
}
I am installing a site under my machine. I have a NodeJS server that listens on port 4000.
I am using an NGINX reverse proxy, so that it is accessible from port 80. Here is the following configuration in / sites-availabes
upstream site {
server 127.0.0.1:4000;
}
server {
listen 80;
server_name site.infra.monsite.blog;
location / {
proxy_pass http://site;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
But I can't access my site from site.infra.monsite.blog; which points to port 80 of the machine.
Are there any ports to open like on Windows, or an NGINX configuration that I missed?
Yet when I do "curl -X GET http://localhost/": It works on the machine.
Thanks for your help.
Try this:
upstream site {
server 127.0.0.1:4000;
keepalive 64;
}
server {
listen 80;
server_name www.example.com;
return 301 https://www.example.com$request_uri;
}
location / {
proxy_pass http://site;
proxy_http_version 1.1;
proxy_redirect off;
proxy_pass_header Set-Cookie;
proxy_set_header Connection 'upgrade';
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_pass_header X-XSRF-TOKEN;
proxy_read_timeout 240s;
}
I am setting up nginx so that I can access my API built using express through a url like - example.com/api
Here is my nginx config
upstream appfrontend {
server localhost:9008 fail_timeout=0;
}
upstream api {
server localhost:3001;
}
server {
listen 80;
listen [::]:80;
server_name hospoline.com www.hospoline.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl;
listen [::]:443;
server_name example.com; # replace this with your domain
root /var/www/html/example-certbot-webroot;
# The public and private parts of the certificate are linked here
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
location /.well-known {
root /var/www/html/example;
}
location / {
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Port $server_port;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://appfrontend;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 900s;
}
location /api {
proxy_pass http://api;
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;
}
}
When I visit my site example.com the front end loads perfectly.
When I visit example.com/api/fetch_doctors, I get a 502 bad gateway error.
My API is working fine in localhost. When I send a request to localhost:3001 on my local computer, I get the list of doctors.
Both my front end server and backend server are run using forever.
I am really lost and breaking my head about this for one full day. I have no idea where I'm going wrong. Any help in the right direction would be great! Thank you all!
