I am an amateur of NGINX, I want to setup NGINX as a Reverse Proxy for my web server.
I would like to know that the NGINX these things as listed below:
When a browser send request with URL: http://nginxproxy.com/client/1.2.3.4/, this request should be passed to the client with IP 1.2.3.4 http://1.2.3.4/, the browser should still show the URL nginxproxy/client/1.2.3.4/
And the same for:
nginxproxy.com/client/2.3.4.5 --> //2.3.4.5
nginxproxy.com/client/2.3.4.6 --> //2.3.4.6
All the others requests that doesn't mach the pattern should come to my default server myserver.
Can I do this by using NGINX?
After researching, I tried with the below configuration:
But unlucky, It doesn't work. The address was changed to http:/1.2.3.4 on browser's address bar, instead of http:/nginxproxy.com/client/1.2.3.4 as expected.
server {
listen 80;
location ~ ^/client {
rewrite ^/client/?(.*) /$2 break;
proxy_pass $scheme://$1;
}
location / {
proxy_pass http://myserver.com;
}
}
Any help is much appreciated.
Doing some more research and based on #Cole input, here is my answer:
location ~ ^/client/(?<site>[^/]+)/? {
rewrite ^.*\/client\/(?<site>[^\/]+)\/?(.*) /$2 break; #passing all the remaining request URIs after <site> group to client server
proxy_pass $scheme://$site;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host/client/$site; #this help to keep the address as it is on the browser's address bar
proxy_set_header X-Forwarded-Proto $scheme;
}
location / {
proxy_pass $scheme://myserver.com
}
server {
listen 80;
location /client/ {
rewrite ^/client/(?<site>[^/]+)/? $scheme://$site;
}
location / {
proxy_pass $scheme://myserver.com;
}
}

I have two react app running on localhost:3000(frontend) and localhost:3001(backend). I want to serve both backend and front end from same server_name.. For example, if a user hits example.com the Nginx should route the traffic to frontend running on (localhost:3000) and if a user hits example.com/admin/login traffic should get routed to the backend (localhost:3001).
'''
server {
listen 80;
server_name example.com;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
location / {
proxy_pass http://localhost:3001;
}
location /admin-login {
proxy_pass http://localhost:3000;
}
}
'''
Using above configuration. I have frontend running on example.com. However, when I call example.com/admin/login I am getting redirected to app running on frontend (localhost:3000) instead of backend running on (localhost:3001).
Updating as per the answer given below. I have below configuration. it still have the same behavior.
server {
listen 80;
server_name example.com;
location /admin-login {
proxy_pass http://127.0.0.1:3000/admin-login;
}
location / {
proxy_pass http://127.0.0.1:3001;
}
location /home {
proxy_pass http://127.0.0.1:3001/home;
}
location /login {
proxy_pass http://127.0.0.1:3001/login;
}
location /signup {
proxy_pass http://127.0.0.1:3001/signup;
}
location /article {
proxy_pass http://127.0.0.1:3001/article;
}
}
I think the problem here is that
location / {
proxy_pass http://localhost:300
}
matches all queries so will also redirect anything to /admin-login
You could either rearrange your blocks to have the admin-login block above the / block in the config file, or make the adjustment below:
location = / {
proxy_pass http://localhost:300
}
This adjusted block should only redirect queries to / rather than /*

I want to proxy request to current network interface hostnames with Nginx such as:
url /catalog/categories/... proxy to hostname catalog:8080 with url /categories/...
url /vitrine/products/... proxy to hostname vitrine:8080 with url /products/...
Is any idea?
The configuration should look like this:
http {
...
server {
listen 80;
server_name yourdomain;
set $mycatalog catalog:8080;
set $myvitrine vitrine:8080;
}
location ~ ^/catalog/categories/(.*)$ {
proxy_set_header Host $host:$server_port;
proxy_pass http://$mycatalog/categories/$1$is_args$args;
}
location ~ ^/vitrine/products/(.*)$ {
proxy_set_header Host $host:$server_port;
proxy_pass http://$myvitrine/products/$1$is_args$args;
}
}
I have multiple backend servers and I want to proxy all servers using a single nginx server instance. I don't want to change nginx.conf whenever I add a new backend server.
For example: Server 1 : 192.168.10.1:8080, Server2: 192.168.10.2:8080, etc
Nginx is running on example.com. I want to access Server1 by using example.com?ip=192.168.10.1, example.com?ip=192.168.10.2 etc
I tried this configuration, but it is giving 500 error page.
location / {
proxy_pass http://$arg_ip:8080;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
Is there something I am missing? Is there any other way of achieving this?
server {
server_name dynamic_host;
listern 8080;
#resolver 8.8.8.8;
#seems you don't need resolver because you use ip address
location / {
if ( $arg_address != "" ) {
proxy_pass $arg_address;
#proxy_pass $arg_address$uri
#proxy_pass $arg_address$request_uri
}
}
}
the difference between the three proxy_pass
$proxy_address
example.com?address=http://192.168.10.2:8080/ goes to
http://192.168.10.2:8080/
$proxy_address$uri
example.com/test/path?address=http://192.168.10.2:8080/ goes to
http://192.168.10.2:8080/test/path
$proxy_address$request_uri
example.com/test/path?address=http://192.168.10.2:8080/¶m=value goes to
http://192.168.10.2:8080/test/path?address=http://192.168.10.2:8080/¶m=value
you can change the param address to ip, in this case, don't forget to change $arg_address to $arg_ip.

Below is a static config of what I'm trying to do.
server {
listen 80;
server_name browser.shows.this.server.com;
location / {
proxy_set_header Host backend.server.com;
proxy_redirect http://backend.server.com/ http://browser.shows.this.server.com/;
}
}
How can I make backend.server.com dynamic for each request? I'd like to pass the domain somehow in the request. Maybe in a header?
You should use proxy_pass instead of proxy redirect. Hope this helps
alternatively can write a config like this
resolver your-server-ip;
set $upstream_endpoint http://your-url;
location / {
rewrite ^/(.*) /$1 break;
proxy_pass $upstream_endpoint;
}

Using my Nginx install I was forwarding my requests to www.example.com:8080/twinkle/index.jsp
location / {
proxy_set_header Host www.example.com;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://localhost:8080/twinkle/;
}
I am deploying another application that is going to primarily be used to download and running on port 81
www.example.com:81/blacksheep/mary/mary.wav
www.example.com:81/blacksheep/tom/tom.wav
location /blacksheep/(.*) {
proxy_pass http://localhost:81/media/(.*) ;
}
However this takes me back to www.example.com/twinkle/blacksheep/xxxxx
Not sure what I am missing.. (I am an amateur in this space, filling up temporarily )
thanks.
I tried the following after Anatoly's comment & it worked.
location /blacksheep {
rewrite ^(/blacksheep)(.*)$ /blacksheep$2 break;
proxy_pass http://localhost:81;
}
