Nginx servers configuration - node.js

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?

ReactJS Router Dom not navigating to dashboard after logging in

Please help. I have my ReactJS NodeJS deployed on Linux NGINX and I can login on my development machine, on my phone, and on Linux OS running on my computer Oracle VM; i can accessed the application on these devices and it worked fine even when I changed IP address but immediately another device e.g somebody else computer or phone tries to login, it would always not redirect to dashboard but my three devices(laptop, phone, and Linux OS running on my computer Oracle VM) can redirect successfully to dashboard after logging in.
I have tried everything on this page below that people provided as solution but to no success :
https://stackoverflow.com/questions/43951720/react-router-and-nginx
Infact, i don't even see their login attempt in the NodeJS API running. My ReactJS build file contents are in /etc/nginx/sites-available/mydomain/ and this is my nginx.config below:
user www www; ## Default: nobody
server { # simple reverse-proxy
listen 80;
server_name mydomain;
# serve static files
#location ~ ^/(images|javascript|js|css|flash|media|static)/ {
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
root /etc/nginx/sites-available/mydomain;
index index.html;
try_files $uri /index.html;
}
location /api {
proxy_pass https://localhost:8084;
root /etc/nginx/sites-available/mydomain;
index index.html;
}
}
server {
listen 443 ssl;
server_name mydomain;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
root /etc/nginx/sites-available/mydomain;
index index.html;
try_files $uri /index.html;
}
location /api {
proxy_pass https://localhost:8084;
root /etc/nginx/sites-available/mydomain;
index index.html;
}
ssl_certificate /etc/letsencrypt/live/mydomain/fullchain.pem; # managed by Certbot;
ssl_certificate_key /etc/letsencrypt/live/mydomain/privkey.pem; # managed by Certbot
#...
}
Please fams, what difference does it make as I have my NGINX configuration in nginx.conf and not default?
As I configured my nginx.conf do I still need to go do the same in /etc/nginx/sites-available/default and what extension is this default config file?

How do I Run React App on Nginx with a node.js backend on AWS EC2?

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.

Node.js app and Apache php back-end at the same server

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;
}
}

Refreshing page always resolves to top level

I am deploying my app on an ec2 machine. There is a node app which corresponds to myapp.com/api. This is working fine. The Client app is built on React and users visit it on myapp.com.
The client app is getting rendered and i am able to navigate to different paths. However when I refresh a page, eg. myapp.com/profile it always resolves to myapp.com.
server {
listen 80;
server_name myapp.com;
root /home/ec2-user/projects/synaid/client/build;
passenger_enabled on;
index index.html;
location / {
root /home/ec2-user/projects/synaid/client/build;
try_files $uri /index.html;
}
location /api {
root /home/ec2-user/projects/synaid/server/build;
rewrite ^/api/(.*) /$1 break;
passenger_enabled on;
passenger_app_type node;
passenger_app_root /home/ec2-user/projects/synaid/server/build;
passenger_startup_file index.js;
passenger_env_var APP_ENV staging;
}
}
What I thing is happening is that when nginx server gets a request it is slicing the url from base path and rendering the index.html to browser. It should also be passing the url forward to the app, which it doesnt seem to be doing.
A possible solution could be to forward url to the app from inside the configuration.

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;
}
}
