Nginx configuration file does not work as expected

  • 772

I have a docker running Nginx on port 80 and I port forwarded to 8080, so I can see it locally in localhost:8080

Using ngrok I created a url. Using the newly created url I can see the Welcome Page of Nginx locally. Lets say my url is http://myurl.ngrok.io/

All I want now is Nginx to listen to requests and if I ask http://myurl.ngrok.io/mylocation it will return 200 and print YES!!!.

This is how I configured nginx.conf:

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;

    server {
       listen 8080 default_server;
       server_name _;
       add_header X-debug-message "A static file was served" always;
       return 200;

       location \mylocation {
           return 200 'YES!!!';
       }
    }
}

After I configured nginx.conf file I hit:

root@ec24***f108:/etc/nginx# nginx -s reload
2021/02/21 13:47:55 [notice] 1048#1048: signal process started

Then going to http://myurl.ngrok.io/mylocation I get 404!

What am I doing wrong?

  1. You have a return 200; in the server block, which will be processed before the location statements. Only put return statements in the server block if that is the only thing the server block needs to do, otherwise, it need to be inside another block.

    The location statement literally matches the URI /*. If you want a location that matches any URI, use location /. See this document for details.

  2. include /etc/nginx/conf.d/*.conf;

    This line means that *.conf (any .conf file) will get higher priority than nginx.conf (the file I showed in my question).

    Inside /etc/nginx/conf.d/default.conf there is a server { } section that gets loaded anytime I asked for the site, and the server { } I wrote in nginx.conf was not considered.

    All I had to do is to mark out the include line from nginx.conf, and then reload the Nginx with

    nginx -s reload

    Now every time the page is loaded, the nginx.conf is considered.
