Force requests to application server by default with Nginx

Question

Noobie question here.

I've setted up Parse-Server in my Ubuntu droplet and i'm currently dealing with an issue here. My ssl is from letsencrypt

In this file

/etc/nginx/sites-enabled/default

I have the following

# HTTP - redirect all requests to HTTPS server { listen 80; listen [::]:80 default_server ipv6only=on; server_name example.com; return 301 https://$host$request_uri; } # HTTPS - serve HTML from /usr/share/nginx/html, proxy requests to /parse/ # through to Parse Server server { listen 443; server_name example.com; root /usr/share/nginx/html; index index.html index.htm; ssl on; # Use certificate and key provided by Let's Encrypt: ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; ssl_session_timeout 5m; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH'; # Pass requests for /parse/ to Parse Server instance at localhost:1337 location /parse/ { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://localhost:1337/; proxy_ssl_session_reuse off; proxy_set_header Host $http_host; proxy_redirect off; } location /test/ { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://localhost:1337/test/; proxy_ssl_session_reuse off; proxy_set_header Host $http_host; proxy_redirect off; } location /dashboard/ { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://localhost:4040/dashboard/; proxy_ssl_session_reuse off; proxy_set_header Host $http_host; proxy_redirect off; } location / { try_files $uri $uri/ =404; } } 

So the followin links are working fine

• https://example.com/parse/
• https://example.com/dashboard/
• https://example.com/test/

but they are working cause of the default file has the code to work fine. I can't do that for all the directories that parse has for example

• https://example.com/parse/serverInfo/

is getting a 404 error.

Is there any way to make all the pages available without having to configure them in the default file?

Update

So when I put this inside my default file

 location /parse/ { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://localhost:1337/parse/; proxy_ssl_session_reuse off; proxy_set_header Host $http_host; proxy_redirect off; } 

I get no 404 error. This is because of the proxy_pass http://localhost:1337/parse/ that is different from the first file that I've posted here.

But how can i do that for ALL the requests no matter /parse/ or /something/ etc? I cannot right down here ALL the folders and possible links that i will create inside server. Because at this domain I will also setup a website which will have /assets/ etc and it will need each single one. Isn't there any code to include ALL the possible links that it will be created?

If you want most requests go to the proxy, but only serve some content directly from nginx, you can use this structure:

location /path/to/nginx/content { try_files $uri $uri/ =404; } location /dashboard { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://localhost:4040/dashboard/; proxy_set_header Host $http_host; proxy_redirect off; } location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://localhost:1337; proxy_set_header Host $http_host; proxy_redirect off; } 

So, first we specify the exceptions to the default procedure, and then the default case.

Note that there is no ending / in the proxy_pass directive in the default case. It means that nginx will append the URI to the request sent to the proxy server, that is, https://example.com/some/path will be proxied to http://localhost:1337/some/path.

I removed the proxy_ssl_session_reuse directive, since it means nothing when the connections to proxy are made with http.

If the proxy connections are made with https, even then it is not useful to disable session resuse, since that degrades performance due to new SSL session negotiation on every request to the proxy.

Then you need to make sure that the root directive specifies a correct directory where nginx can find the static resources. For the root option in your configuration, https://example.com/path/to/nginx/content/example.gif needs to be at /usr/share/nginx/html/path/to/nginx/content/example.gif on the filesystem.
