I am new to the nginx config.
I am trying to do a load balancing example with nginx and wcf rest service in windows platform.
Here is what I have in my conf/nginx.conf file:-
upstream servers_customserver {
server 127.0.0.1:62133;
server 127.0.0.1:64897;
server 127.0.0.1:64921;
}
server {
listen 8070;
location /test {
proxy_pass http://servers_customserver/;
}
My motive is whenever, I try to enter a website name which contains "/test" then redirect to one of the urls in the
"servers_customserver".
Nginx is fine in localhost:8070.
But whenever I did localhost:8070/test, I am getting "404 Not Found nginx/1.12.0" in the browser. I am sure that my services are up.
Do, I need to work with my services in IIS or any webservers to make this to work?
Could some one guide me in solving this error.
Thanks.
Luckily,
After adding the following steps to the location block, the load balancing stuff works for me.
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-Host #server_name;
proxy_redirect off;
Thanks.

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 neither familiar with nginx nor asp.net core. but i'm trying with both.
My nginx server is using default configurations, serving several very simple html pages on 80 port. Currently the homepage is: http://leiyang.icu or https://leiyang.icu.
One net5 built in asp.net core blazor sample app is hosted in a different location from nginx document root, and works well: http://leiyang.icu:8080/
The goal is redirecting:
$host/net --> $host:8080
$host/net/counter --> $host:8080/counter
$host/net/anything --> $host:8080/anything
and so on, while keeping the url in browser.
I've tried simple rewrite rule
rewrite /net(.*) http://leiyang.icu:8080/$1 permanent;
but it shows redirected url in browser, which is not expected.
I tried proxy_pass following Host ASP.NET Core on Linux with Nginx. now if user go to http://leiyang.icu/net/, he can see the page, but css is not loaded(screeshot attached).
location /net/ {
proxy_pass http://localhost:8080/;
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;
}
I guess possible reason is my proxy_pass configuration didn't specify different document roots.
But I cannot figure out how to solve. Could anyone give some suggestions?
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'm flummoxed.
I have a server that is primarily running couchdb over ssl (using nginx to proxy the ssl connection) but also has to serve some apache stuff.
Basically I want everything that DOESN'T start /www to be sent to the couchdb backend. If a url DOES start /www then it should be mapped to the local apache server on port 8080.
My config below works with the exception that I'm getting prompted for authentication on the /www paths as well. I'm a bit more used to configuring Apache than nginx, so I suspect I'm mis-understanding something, but if anyone can see what is wrong from my configuration (below) I'd be most grateful.
To clarify my use scenario;
https://my-domain.com/www/script.cgi should be proxied to
http://localhost:8080/script.cgi
https://my-domain.com/anythingelse should be proxied to
http://localhost:5984/anythingelse
ONLY the second should require authentication. It is the authentication issue that is causing problems - as I mentioned, I am being challenged on https://my-domain.com/www/anything as well :-(
Here's the config, thanks for any insight.
server {
listen 443;
ssl on;
# Any url starting /www needs to be mapped to the root
# of the back end application server on 8080
location ^~ /www/ {
proxy_pass http://localhost:8080/;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
# Everything else has to be sent to the couchdb server running on
# port 5984 and for security, this is protected with auth_basic
# authentication.
location / {
auth_basic "Restricted";
auth_basic_user_file /path-to-passwords;
proxy_pass http://localhost:5984;
proxy_redirect off;
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-Ssl on;
}
}
Maxim helpfully answered this for me by mentioning that browsers accessing the favicon would trigger this behaviour and that the config was correct in other respects.
I am trying to use nginx to enforce basic authentication before allowing access to the H2 database web console. This console is running on https://localhost:8084
In my nginx.conf, I have:
location /h2 {
auth_basic "Restricted";
auth_basic_user_file htpasswd;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto https;
proxy_pass https://localhost:8084/;
}
What I want it to do is proxy requests for /h2 to H2's webserver. This configuration works for the first request, however the H2 server immediately sends a HTTP redirect for "/login.jsp" which is getting sent to my browser as "/login.jsp" and not "/h2/login.jsp". This means that when my browser requests the page, the request fails because only urls at location "/h2" get passed to the H2 webserver.
How can I append "/h2" to any redirects returned by the H2 webserver? I tried the following:
proxy_redirect https://localhost:8084/ https://$host/h2;
but it didnt do anything.
This seems to be a nginx config problem. Try location /h2/ (with trailing slash) instead of location /h2 in the nginx.conf. And then connect to http://localhost/h2/. You don't need any reverse-proxy config, as the H2 Console tool doesn't use absolute URLs (it redirects goes to "login.jsp" and not to "/login.jsp"). The problem is that http://localhost:/h2 is a 'file name', whereas http://localhost:/h2/ is a 'directory'.
