How to configure multiple virtual hosted nodejs apps on same machine with different port to nginx conf? I tried location tag with different proxy_pass but it throws no css js error on one location and on another it’s get method error..
Please help me out. thanks!!
You can do it simple like this for instance:
server {
listen 80;
server_name yourdomain.com;
location / {
proxy_pass http://localhost:3000;
}
}
server {
listen 80;
server_name yourotherdomain.com;
location / {
proxy_pass http://localhost:3001;
}
}

I am trying to run a react app with Node.js backend on the Nginx server.
Here's my server block in the nginx.conf file:
include /etc/nginx/conf.d/*.conf;
server {
listen 80;
listen [::]:80;
server_name _;
root /usr/share/nginx/folder-name/frontend/build;
index index.html index.htm;
location / {
proxy_pass http://localhost:5000;
}
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
The build folder contains the compiled react js code(using npm run build)
Node.js backend is running on port 5000 using pm2/forever.
After restarting the Nginx Server, the react UI appears on the server IP but the UI is distorted.
Also, I am not able to access my backend APIs on MyIP/api/endpoint.
What am i doing wrong.? This nginx configuration was built from SO and other online resources so there's a huge probabilty that it could be wrong. Please help!
Thanks in advance!
The issue is you are setting the API proxy for the root (/). The correct one should look like this:
server {
listen 80;
listen [::]:80;
server_name _;
root /usr/share/nginx/folder-name/frontend/build;
index index.html index.htm;
location /api {
proxy_pass http://localhost:5000;
}
location / {
try_files $uri $uri/ =404;
}
}
If you don't have /api path in your Node.js, you will need a rewrite rule for it like this:
location /api {
rewrite ^/api/?(.*) /$1 break;
proxy_pass http://localhost:5000;
proxy_redirect off;
proxy_set_header Host $host;
}
I had experience that.Please check my image file
This configuration is running successfully on aws.
Your mistakes is proxy area. Please change like that.
location /api/ {
proxy_pass http://127.0.0.1:5000/api/
}
If you want, I can HELP you.
Yes, you can host both API and static files (build files of your front-end) on the same domain or host. Below, you can find a server block for a sample API hosted on port 3000 and static HTML files at a root location being served on port 80.
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
error_page 404 index.html;
}
location /api/ {
proxy_pass http://localhost:3000/;
}
}
You can access the front-end at http://localhost/<blah...> and the API at http://localhost/api/<blah...> (please note how /api is handled in the URL here and the server block above). Replace localhost with your domain name.
What am i doing wrong.?
One issue is with your proxy_pass directive. You are missing trailing slash /
...
location / {
proxy_pass http://localhost:5000/;
}
...
First, try this and share your result.
I have a VPS which runs under CentOS 7.
The idea is: to have under maindomain.com node.js front-end app deployed while under api.maindomain.com to have php back-end deployed. Is it possible? Say, add server blocks to Nginx: reverse proxy localhost:4000 for node.js app and the other block for localhost:80 for php back-end.
Maybe there exists the other solution, I don't know, I would appreciate any ideas! The main goal: to have both app at the same server.
Solution 1 with www.maindomain.com + api.maindomain.com
Frontend
server {
listen 80;
server_name www.maindomain.com;
location / {
root /path/to/your/files;
try_files /index.html;
}
}
Backend php API
server {
listen 80;
server_name api.maindomain.com;
location / {
proxy_pass http://localhost:4000;
}
}
Solution 2 everything on same domain, www.maindomain.com
server {
listen 80;
server_name www.maindomain.com;
location /api {
proxy_pass http://localhost:4000/api;
}
location / { # always at the end, like wildcard
root /path/to/your/files;
try_files /index.html;
}
}
Have two Sub Domains, app.example.com and admin.example.com, using nginx v 1.14.1, express js.
Bugs:
The ports are running in both subdomains eg: 8080 runs in app.example.com and admin.example.com how can I prevent this?
It's not redirecting to 80 after entering subdomains with port number 8080 and 8081. or I should prevent entering this port number from URL.
virtual.conf
server {
listen admin.example.com:80;
server_name admin.example.com;
location / {
proxy_pass http://127.0.0.1:8080;
}
}
server {
listen app.example.com:80;
server_name app.example.com;
location / {
proxy_pass http://127.0.0.1:8081;
}
}
Solved :
Changed server.js line app.listen('8080') to app.listen('8080', '127.0.0.1')
Restarted the nginx then got nginx welcome page for all my subdomains and private IP.
Removed subdomain name from virtual.conf at the line of listen.
Restared nginx again.
virtual.conf
server {
listen 80;
server_name admin.example.com;
location / {
proxy_pass http://127.0.0.1:8080;
}
}
server {
listen 80;
server_name app.example.com;
location / {
proxy_pass http://127.0.0.1:8081;
}
}
Node js part:
app.listen(4000,"localhost");
Nginx default:
server{
server_name "mydomain";
location /{
proxy_pass http://localhost:4000;
}
}
When i set it with localhost it's working.
When i run the node script on another server and set nginx configuration like this:
server{
server_name "mydomain";
location /{
proxy_pass http://192.168.1.30:4000;
}
}
This is not working. I'm getting 502 Bad Gateway error when i try to connect "mydomain".
I've solved the problem with changing the node script.
app.listen(4000,"localhost"); to app.listen(4000);
I’m trying to configure nginx. I have 2 node.js servers in my project. First is working. And here’s nginx configuration file for it:
server {
listen 80;
server_name www.myhоst.com
location / {
root /home/my-project/server1/app;
index index.html index.htm;
proxy_pass http://server1_ip:8080/;
}
location /server_2 {
root /home/my-project/server2/app;
index index.html index.htm;
proxy_pass http://server2_ip:5050/;
}
}
The first server is running correctly when I’m opening www.myhоst.com/ , but the second one when I’m passing www.myhost.com/server2 link is not. How I can fix it?
