I'm new to nginx. I have two projects, and the one is django web app which is running localhost 8000, and another is tornado which used to provide api service and running localhost 8888.
How do I config the nginx that redirects all the url requests(from 80 port) to localhost:8000 but /api requests to localhost:8888(tornado app)?
Edit your nginx config file. Add a server block and use proxy_pass in location blocks to proxy (redirect) the request.
server {
listen 80;
location / {
proxy_pass http://127.0.0.1:8000;
}
location /api {
proxy_pass http://127.0.0.1:8888;
}
}
Save it, and reload nginx.
nginx -s reload

I want to use nginx to route to different application via path. I use the following nginx config (minimal example):
server {
listen 80;
http://example.com;
location /myapp/ {
rewrite ^/myapp/(.*)$ /$1 break;
proxy_pass http://localhost:port;
}
}
The request is working but some application do route back the response to the root. Instead of
http://example.com/myapp/*
I end up again on
http://example.com/*
Is there a way, that nginx does route all request from /myapp/* to http://localhost:port/* (application root) and route back the response to /myapp/*
So far I didn't find a solution.
Thanks
I have a front-end react app, that runs at localhost:3000. And a back-end that runs at localhost:9900.
I can access my back-end with a postman's(or curl) localhost:80/api request.
But I can't access either the site or the server via the web address: my-1stconnection.lan.test.
What's the problem?
NGINX config:
server {
listen 80;
listen [::]:80;
server_name my-1stconnection.lan.test;
location / {
proxy_pass http://localhost:3000/;
}
location /api {
proxy_pass http://localhost:9900/;
}
}
I forgot one important thing in order to activate the local server:
127.0.0.1 my-1stconnection.lan.test into /etc/hosts
After this fix, everything started working.
I have a server running with Nginx reverse proxy.
We have our application running in another server, which is served using this Nginx proxy. Below is the configuration I have used and its working fine.
location / {
rewrite ^/(.*) /$1 break;
proxy_pass http://10.0.0.121:8000;
}
I would need to download a pdf file in the application machine (10.0.0.121) , which is under /home/ubuntu/app/pdf/data-2021-03-25.pdf.
How could I make the file in application machine downloadable from the proxy server, please help.
Thanks in Advance.
I would simply install another nginx instance on 10.0.0.121 and configure it like this. NON-PROD READY!
server {
listen 8080;
server_name ...;
root /home/ubuntu/app/pdf;
location = /data-2021-03-25.pdf {
try_files $uri $uri/ =404;
}
server {
listen 8090;
location / {
proxy_pass http://localhost:8080;
}
}
}
Not tested but this server will handling the request serving the file. Then you could just use proxy_pass on the other server to proxy the request.
But beside from this option you can use a python, perl, php, java, nodejs, assembly or what ever programming language you want to use to open a http port and serve the file on an incoming request. Its really your choice.
just make sure if you're going for the proxy solution you are sanitizing the requests on your proxy. For example. With a small change in the setup above you could cheat and get any other files from your home/app directory by sending an request like curl -v localhost:8090/pdf/../other/file. So make sure you are using the root(/home/ubuntu/app/pdf/) directive and set a location matching the pdf-file on the proxy-server as well.
That worked in my demo app.
My initial NGINX load balancer configuration was pretty simple:
upstream myapp {
server 10.11.12.13:80; #server01
server 10.11.12.14:80; #server02
}
server {
listen 80;
server_name localhost;
location /myapp/ {
proxy_pass http://myapp;
Let's say the localhost has the IP 1.2.3.4.
Result:
The user calls 1.2.3.4/myapp and gets redirected to one of those two servers including the requested filepath.
For example: 1.2.3.4/myapp/results gets redirected to maybe 10.11.12.13/myapp/results.
Now I have ONE special case to include, this is where I struggle. ALL requests should still be handled exactly the same with this one exception:
If 1.2.3.4/specialFilePath is called I want to redirect to a totally different, static URL e.g. externalPage.com.
Can I add this case somehow to my Nginx configuration?
You could add a second location block in which you defile what to do with the specialFilePath like
location /specialFilePath {
proxy_pass http://externalservice.com;
}
Then check the configuration with nginx -t or sudo nginx -t and reload the configuration
I have met an annoying issue for Nginx Load Balancer, please see following configuration:
http {
server {
listen 3333;
server_name localhost;
location / {
proxy_pass http://node;
proxy_redirect off;
}
}
server {
listen 7777;
server_name localhost;
location / {
proxy_pass http://auth;
proxy_redirect off;
}
}
upstream node {
server localhost:3000;
server localhost:3001;
}
upstream auth {
server localhost:8079;
server localhost:8080;
}
}
So what I want is to provide two load balancers, one is to send port 3333 to internal port 3000,3001, and second one is to send request to 7777 to internal 8079 and 8000.
when I test this setting, I noticed all the request to http://localhost:3333 is working great, and URL in the address bar is always this one, but when I visit http://localhsot:7777, I noticed all the requests are redirected to internal urls, http://localhost:8080 or http://localhost:8079.
I don't know why there are two different effects for load balancing, I just want to have all the visitors to see only http://localhost:3333 or http://localhost:7777, they should never see internal port 8080 or 8079.
But why node server for port 3000 and 3001 are working fine, while java server for port 8080 and 8079 is not doing url rewrite, but only doing redirect?
If you see the configuration, they are exactly the same.
Thanks.
