Here is what I need,
when its localhost:80 I need Nginx welcome page to be served, but when its localhost:80/pass, my application(react app) to be served, here is my Nginx.conf looks like,
server {
listen 80;
server_name localhost;
location /pass {
root build;

Sorry, the page you are looking for is currently unavailable.
Please try again later.If you are the system administrator of this resource then you should check the error log for details.Faithfully yours, nginx.
here is my error.log

I can set up nginx as a reverse proxy with no major issues, but if I do a simple static page test like this, the server doesn't serve pages:
server {
server_name localhost;
listen 12345;
location / {
root /Volumes/E/static/;
index index.html index.htm;
}
}
error.log says:
2023/02/09 22:39:10 [crit] 53512#0: *18710 open() "/Volumes/E/static/index.html" failed (1: Operation not permitted), client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost:12345"
...and I get a "500 Internal Server Error" in the browser when entering http://localhost:12345/.
I've tried chmod -R 755 /Volumes/E/static, no effect.
Why is that?
I have the following nginx configuration which returns 502
server {
listen 2052;
listen 2082;
server_name good.abc.com;
location / {
proxy_pass http://goodServer:$server_port;
}
}
Testing:
proxy_pass http://goodServer:2052; When the fixed port is 2052
curl good.abc.com:2052 It can be accessed normally.
Question:
The port I want to forward user requests to
For example.
curl good.abc.com:2052 ---> goodServer:2052
curl good.abc.com:2082 ---> goodServer:2082
So the port must be a variable, just like $server_port
Log:
2021/04/04 14:10:11 [error] 24#24: *19 good could not be resolved (3: Host not found), client: 162.158.91.119, server: good.abc.com, request: "GET / HTTP/1.1", host: "good.abc.com:2052"
I have two domains, let's say ex.io and example.com. I own both and have access to both servers. Both run NGINX.
Goal: I'd like to have any request from ex.io forward to a specific path under example.com, e.g. http://ex.io passes to https://example.com/foo/bar. This has to be done without a redirect (more in Context)
Context: The goal is to host a shell script at https://example.com/foo/bar so that curl ex.io | sh will run the shell script. I'd like no redirects to happen so no additional flags are needed for curl.
My current .conf setup for both servers follows:
server {
listen 80;
listen [::]:80;
server_name example.com
return 308 https://$host$request_uri;
}
server {
listen 80;
listen [::]:80;
server_name ex.io;
return 308 https://example.com/foo/bar;
}
# ...
This works, but requires the extra flag -L to run properly under curl. How can I proxy ex.io to go directly to https://example.io/foo/bar?
EDIT: I'm forwarding http://ex.io/ to https://example.com/foo/bar which may be tricky going from http to https. Bananenkönig's response fails with a 502 Bad Gateway error and the following logs:
2020/10/26 23:28:45 [error] 223#223: *281 SSL_do_handshake() failed (SSL: error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure:SSL alert number 40) while SSL handshaking to upstream, client: XXX.XXX.XXX.XXX, server: ex.io, request: "GET / HTTP/1.1", upstream: "https://XXX.XXX.XXX.XXX:443/foo/bar/", host: "ex.io"

I would try it like this:
server {
listen 80;
listen [::]:80;
server_name ex.io;
location /some/location/on/ex.io/ {
proxy_pass https://example.com/some/location/on/example.com/;
}
}
when you want ex.io/ (on location /) to be forwarded to example.com/... write "location / { "
what is happening:
Im using following nginx.conf file for load balancing. web application is up and running on nginx 8080 port and able to access the landing page. however, when moving from landing page to "signup" page, it is throwing error.
what is expected:
nginx load balancer should redirect the load to the page as mentioned in the Location directive. but that is not happening.
nginx file :
events {
}

as per log, it is expecting signup html file. however, i am instructing it to use the add-user.html file. not sure why this is not happening.
please suggest
You want to point the URI /signup to the file located at /etc/nginx/html/add-user.html
There are a number of ways to achieve that using Nginx, including the rewrite and try_files directives.
For example:
location /signup {
try_files /add-user.html =404;
}
The root directive does not need to be repeated within this location block, as it will inherit the same value from the surrounding block.
The =404 does nothing as add-user.html always exists, but try_files requires two parameters. See this document for details.
The above location will process any request that begins with /signup (e.g. /signup/ or /signups).
To restrict it to the single URI /signup use the = modifier. See this document for details.
For example:
location = /signup {
try_files /add-user.html =404;
}
In an attempt to implement the upload progress module, the following server configuration is resulting in too many open files error

The following is the relevant part of the server bloc which is generating the conflict
passenger_enabled on;
rails_env development;
root /home/user/app/current/public;
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location / {
# proxy to upstream server
proxy_pass http://127.0.0.1;
proxy_redirect default;
# track uploads in the 'proxied' zone
# remember connections for 30s after they finished
track_uploads proxied 30s;
}
location ^~ /progress {
# report uploads tracked in the 'proxied' zone
report_uploads proxied;
}
Being a relative n00b to nginx, I do not comprehend where this is generating the too many files error. I assumed that the error pages are only for 500-504 server errors...
First check and increase open files limit in the root shell (system-wide, it is 1024 usually):
# ulimit -n
# ulimit -n 16384
Then you can increase nginx's open files limit (main context, top of nginx.conf):
worker_rlimit_nofile 16384
Then restart nginx )
