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 an octoprint server running at http://192.168.1.205. I also have an nginx server hosting myDomain. I want to be able to use the nginx server to pass on a request for http://myDomain/octo to http://192.168.1.205 using a reverse proxy. Here is my nginx code...
server {
server_name myDomain;
location /octo/ {
rewrite ^/octo/(.*) /$1 break; #strip /octo from url
proxy_pass http://192.168.1.205;
}
}
The first http://myDomain/octo request is passed on to http://192.168.1.205 correctly. But after the first response the code in the client makes another request to http://myDomain/moreUri. Since this uri doesn't have /octo nginx doesn't know to send it to http://192.168.1.205/moreUri. Is there a way to have nginx change something in the first response so that the client then makes following requests to http://myDomain/octo/moreUri?
I was able to accomplish this for a case where the octoprint server responded with a redirect. I used ...
proxy_redirect http://192.168.1.205/ http://myDomain/octo/;
and it worked. But that only works on redirects and the following requests were wrong again.

I am not aware that this is possible.
What about to adjust the nginx configuration accordingly ? using location / to process all requests within that block and add an additional redirect directive to address the "Since this uri doesn't have /octo nginx doesn't know to send it to http://192.168.1.205/moreUri" should do the trick.
server {
server_name myDomain;
location / {
rewrite ^/octo/(.*) /$1 break; #strip /octo from url
rewrite ^/(.*)/(.*) /octo/$2 break; #rewrite /moreURI to /octo/moreURI
proxy_pass http://192.168.1.205;
}
}
No matter if the above nginx reconfiguration fixes your issue, i assume the root cause why you need to configure the nginx as reverse proxy in this way might be a misconfigured (or not optimally configured) application. Check the config file if it is possible to configure the applications base path. If so, set it to /octo/ (so the application itself prepends /octo/ to all the links it presents to the user and all requests to the backend automatically) and adjust the rewrite rules accordingly.
Currently i'm using nginx server and using nodejs server as reverse proxy.
I want to make the nginx server proxy_pass different server by location.
So, lets say my domain is subdomain.domain.com.
When loading subdomain.domain.com/, this should serve static files.
When loading subdomain.domain.com/example1/req1/req2, this should route to 127.0.0.1:3000/req1/req2.
When loading subdomain.domain.com/example2/req1/req2, this should route to 127.0.0.1:8080/req1/req2.
But my configuration routes subdomain.domain.com/example1/req1/req2 to 127.0.0.1:3000/example1/req1/req2 resulting error. (nodejs returns Cannot GET /example1)
How should I write this nginx conf file properly?
Try use rewrite directive in location block.
Something like:
location /example1/ {
rewrite ^/example1/(.*)$ /$1 break;
proxy_pass http://xxxxxx;
}
You can check documents related to rewrite module at http://nginx.org/en/docs/http/ngx_http_rewrite_module.html
You need to add below code snippet to your nginx.conf.
server subdomain.domain.com;
location / {
rewrite ^/example1/(.*)$ /$1 break;
proxy_pass http://127.0.0.1:3000;
}
}
I'd like to reverse proxy my application under server.com/myapp/homem where server.com/myapp is the proxied address and /home is an URL handled by my app.
What is the best / recommended solution to do that so that the app will generate proper paths<img src="/myapp/static/...">
Which of the two following approaches I should take:
1. X-Forwarded-Path: I proxy GET Path=/home and add an X-Forwarded-Path: /myapp
2. Base_url set in config: I proxy GET Path=/myapp/home and set base_url = server.com/myapp
The nginx rewrite directive can handle what you are looking for
You server block should look similar to the following snippet
server {
listen 80;
rewrite ^/myapp/(.*)$ /$1 last;
location /home {
proxy_set_header X-Forwarded-Path myapp;
proxy_pass http://1.2.3.4;
}
}
Take a look at either of the following for more information

http://nginx.org/en/docs/http/ngx_http_rewrite_module.html
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'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
