I'm serving a website, generated by a docker container, using nginx, which also lives in a docker container. This setup works quite well.
What I want to do now, is serve multiple websites, from multiple containers.
My (simplified) setup is below.
http {
upstream app_01 {
server container_01:80;
}
upstream app_02 {
server container_02:80;
}
server {
listen 443 ssl;
include common.conf;
include /etc/nginx/ssl.conf;
location / {
proxy_pass http://app_01;
proxy_redirect off;
include common_location.conf;
}
location /alternative {
proxy_pass http://app_02;
proxy_redirect off;
include common_location.conf;
}
}
}
common_location.conf contains:
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Host $server_name;
proxy_set_header X-Forwarded-Port $server_port;
My original website still works fine (container_01), and I can kinda access the second site (container_02); the starting page gets loaded partially. It appears that it keeps the upload/ part in all links.
My question: how do I get this to work?
Since nobody seems to be able to answer, I ended up using an alternative to nginx, which worked within ten minutes.

I'm having some issues hosting blazor WASM standalone (without an asp.net core project as host) behind nginx as a reverse proxy.
Here is my Nginx default config file:
server {
listen 80;
listen [::]:80;
server_name localhost;
location / {
root /var/www/web/BlazorApp/wwwroot;
try_files $uri $uri/ index.html =404;
include /etc/nginx/mime.types;
types {
application/wasm wasm;
}
default_type application/octet-stream;
}
location /service1/ {
proxy_pass http://localhost:5001/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
location /service2/ {
proxy_pass http://localhost:5002/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
location /service3/ {
proxy_pass http://localhost:5003/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
This Configuration works in the sense that I can access my blazor app using
http://{server-ip-address}
and my other services using
http://{server-ip-address}/serviceX
where X would refer to service 1,2 and 3 respectively
First issue: when I navigate in my blazor app for example to http://{server-ip-address}/My-Blazor-Page and I refresh the page I get a 404 not found error.
for it to work back again I need to go back to the base address http://{server-ip-address} and navigate back to My-Blazor-Page.
I cannot refresh a page and go back to the same page.
Second issue: I would like my blazor app to have a different location. I would like to use http://{server-ip-address}/Blazor rather than http://{server-ip-address}/.
I tried everything to get it right but this is the only config that semi-works
Many thanks for your help!
The following nginx.conf file is simplified to show how to configure Nginx to send the index.html file whenever it can't find a corresponding file on disk.
When setting the NGINX burst rate limit with limit_req, Blazor WebAssembly apps may require a large burst parameter value to accommodate the relatively large number of requests made by an app. Initially, set the value to at least 60:
Increase the value if browser developer tools or a network traffic tool indicates that requests are receiving a 503 - Service Unavailable status code.
For more information on production Nginx web server configuration, see Creating NGINX Plus and NGINX Configuration Files.
The above will try the URL, and if no file matches, it'll serve index.html instead. This is the way.
For your second issue, you should set the base attribute value to "Blazor" and put all files in the Blazor directory (the config needs to match this). You can also route differently, but this is the easiest.
I've just deployed a flask application with Gunicorn and Nginx. The application is running under 192.168.25.49 address. Nginx configured as following:
server {
listen 80;
server_name 192.168.25.49;
location / {
include proxy_params;
proxy_redirect off;
proxy_set_header host $host;
proxy_set_header X-real-ip $remote_addr;
proxy_set_header X-forward-for $proxy_add_x_forwarded_for;
proxy_pass http://unix:/home/avin/Saba/saba.sock;
}
}
The problem is: When I enter 192.168.25.49 in the address bar, it automatically changes to http://192.168.25.49,192.168.25.49/login. This problem occurs on login and logout too.
I've searched whole the internet but nothing found for this problem. If anyone with Nginx knowledge help me will appreciate.
I don't know what else or how to ask Google so I come here.
I have this nginx config file (apache.servers.conf is the name):
server {
listen 80;
server_name mysite.com www.mysite.com;
location / {
proxy_pass http://xxx.yyy.zzz.235:8080;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
But no matter what, headers are not showing on the phpinfo();
According to this: https://www.digitalocean.com/community/tutorials/how-to-configure-nginx-as-a-web-server-and-reverse-proxy-for-apache-on-one-ubuntu-16-04-server
The variables HTTPXREAL_IP and HTTPXFORWARDED_FOR were added by Nginx
and should show the public IP address of the computer you're using to
access the URL.
I've already replace mysite and xxx.yyy.zzz.235:8080 with the corresponding values
But is not showing on my phpinfo();
This is for a reserve proxy server. Apache and Nginx themselves are working fine but can't say the same about the headers.
Any help will be appreciated!
Thanks a lot!
I have a main server running NGINX and a second server running Apache/cPanel.
What we are trying to do is keep our micro sites seperate from the main server. The micro sites are mainly Wordpress
The issue that I am running into is that we want them to have the domain format of http://example.com/path.
However it has come to my attention that using the following proxy_pass below it does not work for more then one site.
It also has been recommended to me that the microsites get turned into subdomains on the second server to ease the proxy_pass confusion - path.example.com
I then run into the issue of how do I get http://example.com/path to mirror path.example.com and work like http://example.com/path
Currently it semi works by using the below however /private just loads /blog
Config:
location /blog/ {
include proxy-pass-settings.conf;
proxy_pass http://blogging.example.com/;
}
location /private/ {
include proxy-pass-settings.conf;
proxy_pass http://blogging.example.com/;
Proxy Config:
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forward-Proto http;
proxy_set_header X-Nginx-Proxy true;
proxy_redirect off;
Try this:
location ^~ /blog/ {
include proxy-pass-settings.conf;
proxy_pass http://blogging.example.com;
}
location ^~ /private/ {
include proxy-pass-settings.conf;
proxy_pass http://blogging.example.com;
}
If proxy_pass is specified without a URI, the request URI is passed to the server in the same form as sent by a client when the original request is processed, or the full normalized request URI is passed when processing the changed UR.

I currently have APIs running under http://example.com/api/v3/ and I want to move the APIs to a different server at http://exampleapi.com/v3.
I first thought about creating a location block in nginx to handle the requests such as:
location ~*/api/(v[0-9]+/[a-zA-Z0-9_]+) {
return 301 $scheme://exampleapi.com/$1;
}
However, using a REST client, the requests are being received as GET requests not POST. Same thing using a browser (Firefox).
I have tried the proxy pass but I was not able to make it work. This is what I tried:
location ~*/api/(v[0-9]+/[a-zA-Z0-9_]+) {
proxy_pass http://exampleapi.com/$1;
# proxy_redirect http://exampleapi.com/ /;
proxy_read_timeout 60s;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
I am getting 502 or 500.
What is the best way to achieve moving the APIs?
After debugging locally the same issue, I found out that I cannot proxy pass to a domain, but only to IP address as there is no resolver to resolve this domain.
Hence I created a new server block for exampleapi.com to listen on a port, and proxy passed to that port, such as:
location ~*/api/(v[0-9]+/[a-zA-Z0-9_]+) {
proxy_pass http://127.0.0.1:4545/$1;
proxy_read_timeout 60s;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
