Why I'm getting frequent 504 Time out error? - nginx

my nginx configuration is as:
upstream app_server {
server unix:/run/DigitalOceanOneClick/unicorn.sock fail_timeout=0;
}
server {
listen 80;
root /home/rails/rails_project/public;
server_name example.com www.example.com;
index index.htm index.html;
location / {
try_files $uri/index.html $uri.html $uri #app;
}
location ~* ^.+\.(jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|mp3|flv|mpeg|avi)$ {
try_files $uri #app;
}
location #app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
proxy_read_timeout 180;
proxy_http_version 1.1;
proxy_set_header Connection "";
}
}
And unicorn configuration file is as:
listen "unix:/run/DigitalOceanOneClick/unicorn.sock"
worker_processes 4
user "rails"
working_directory "/home/rails/rails_project"
pid "/run/DigitalOceanOneClick/unicorn.pid"
stderr_path "/var/log/unicorn/unicorn.log"
stdout_path "/var/log/unicorn/unicorn.log"
I'm getting "504 Gateway Time-out" error frequently. I'm not getting any idea about the problem. Server OS is Ubuntu 14.04 with rails5.1.3, nginx and unicorn. Thank you.

Nginx reverse proxy returns 404 on static files

Basically I have two local application hosted on 2 different local port.
I'm trying to access http://localhost/admin which is serve via reverse_proxy but I got http://localhost/admin/main.css net::ERR_ABORTED 404 (Not Found).
Ive also tried below (without slash) but I still got the same error.
location /admin{
proxy_pass http://127.0.0.1:8090

server{

It would be great if someone can explain to me what I'd miss? Thanks much.

Nginx - location block misconfigured?

I have a location block inside of my sites-enabled example.conf that should be routing /testing to a 503 error html page but instead for some reason its hitting my app instead of nginx
[2020-06-30T20:36:13.821768 #6059] FATAL -- : [fc9cb972-f314-4a87-89d9-8334521767b3] ActionController::RoutingError (No route matches [GET] "/testing"):
that is a log line from my actual rails app - why is it even getting this far vs nginx routing to where I thought I told it to???
my nginx .conf

Nginx SPA Serving Static Files, Proxying API Calls, and Rewriting to /index.html

So, I'd like to have an nginx.conf that...
Serves all /static requests directly
Proxies all /api requests to another local server (port 8200)
Serves /index.html for all other requests (so, /contact/123 would really serve /index.html)
Here is my current config...
server {
listen 80;
server_name www.xyz.io;
root /opt/xyz/www;
location / {
try_files $uri $uri/ #backend;
}
location #backend {
proxy_pass http://127.0.0.1:8200;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
}
}
I'm really not clear how to have all other requests serve /index.html though. Ideas?
Try this:
server {
listen 80;
server_name www.xyz.io;
root /opt/xyz/www;
# index
index index.html;
# $uri, index.html
location / {
try_files $uri $uri/ /index.html;
}
location /api {
proxy_pass http://127.0.0.1:8200;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
}
}

nginx proxy_pass static assets

I have the following nginx configuration
rewrite_log on;
server {
server_name greymarmita.no-ip.org;
listen 80;
rewrite ^(.*) https://$host$1 permanent;
}
server {
server_name greymarmita.no-ip.org;
listen 443 ssl;
error_log /var/log/nginx/main.error;
access_log /var/log/nginx/main.access;
ssl on;
ssl_certificate /etc/ssl/localcerts/autosigned.crt;
ssl_certificate_key /etc/ssl/localcerts/autosigned.key;
root /srv/www;
index index.html /index.html;
location /rasp/ {
proxy_pass http://192.168.2.6:81/;
}
location /cam/ {
proxy_pass http://192.168.2.4:8081;
}
location ^~ /router/ {
proxy_pass http://192.168.2.1/;
}
location /nas/ {
proxy_pass http://192.168.2.13/;
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;
}
}
However when I try to access http://192.168.2.6/nas although the html files are served correctly, files under /web/ are not
GET https://greymarmita.no-ip.org/web/images/login.png 404 (Not Found)
The correct path for these assets should be https://greymarmita.no-ip.org/nas/web/images/login.png
You don't have a location to match that file, try adding this
location / {
try_files $uri $uri/;
}

nginx try_files from proxy'd app, then nginx

I'm attempting to have nginx reverse proxy static files from an application if the application is serving them, else serve them itself. Currently, I have this configuration:
upstream app_server {
server unix:/tmp/gunicorn.sock fail_timeout=0;
}
server {
listen 8080;
server_name example.com;
access_log /var/log/nginx.access.log;
error_log /var/log/nginx.error.log;
keepalive_timeout 5;
location /static {
try_files $uri #proxy_to_app;
alias /path/to/__static;
sendfile off;
}
location / {
try_files $uri #proxy_to_app;
}
location #proxy_to_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
}
}
This works if the files don't exist in /path/to/__static; it sends the request to the application server. However, if the files also exist in /path/to/__static, nginx serves the files itself.
Reversing the try_files line (try_files #proxy_to_app $uri) fails in both cases. If the client requests /static/css/test.css, the application receives a request for /css/test.css, and it never seems to try /path/to/__static even though the application returns a 404.
Updated to include full configuration.
location /static/ {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
proxy_intercept_errors on;
error_page 404 =200 /local$uri;
}
location /local/static/ {
internal;
alias /path/to/__static/;
}
