Serving static files via nginx instead of express - node.js

I know there are quite a few threads on this topic, but unfortunately none of them helped me so far. I had an express application and served my static files like this:
app.use(express.static(path.join(__dirname, 'public'), { maxAge: 86400000 }));
Now I'm using nginx aswell and wanted to serve my static content only via nginx, so I commented the line above and added the following to my sites-enabled/default nginx config:
server {
listen 443 ssl;
// certificate, server_Name
location ~^/(images/|img/|javascript/|js/|css/|stylesheets/|flash/|media/|static/|robots.txt|humans.txt|favicon.ico) {
root /path/to/my/project/public/;
access_log off;
expires 24h;
}
}
location / {
proxy_redirect off;
proxy_pass https://127.0.0.1:8443;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_set_header X-NginX-Proxy true;
proxy_set_header Connection "";
proxy_cache_bypass $http_upgrade;
proxy_cache one;
proxy_cache_key sfs$request_uri$scheme;
}
From what I've read so far the first location block should handle the serving of static files (all my static files are located under public). But when I start my application like this I get ERR_TOO_MANY_REDIRECTS. Only once I add the express config from above my site works.
How can I serve static content via nginx correctly?
Does anyone have some guidance on what exactly I'm doing wrong?

nginx throws 404 on redirecting through proxy_pass to nodejs app

I'm serving multiple nodejs apps on a single server through pm2 and using nginx to manage reverse proxies. Right now if I use the server's ip and app port to reach the apps directly it all works fine. But if I try to navigate to my apps through the location paths set in the nginx config then I get 404 errors.
Below is my nginx default config:
upstream frontend {
server localhost:3000;
}
upstream backend {
server localhost:8000;
}
server {
listen 443 ssl;
server_name <redacted>;
ssl_certificate <redacted>.cer;
ssl_certificate_key <redacted>.key;
error page 497 301 =307 https://$host:$server_port$request_uri;
location /app/frontend {
proxy_pass http://frontend;
proxy_redirect off;
proxy_set_header Host $host:$server_port;
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;
}
location /api {
proxy pass http://backend;
proxy_redirect off;
proxy_set_header Host $host:$server_port;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Ssl on;
}
}
server {
listen 80;
server_name <redacted>;
return 301 https://$server_name$request_uri;
}
Now when I try to go to https://<server ip>:3000, the frontend loads just fine but if I go to https://<server ip>/app/frontend, I get the following 404 error:
Although the index.html loads up, it tries to find the static assets on https://<server ip>/ but rather should try to find them on https://<server ip>:3000. This is the exact behaviour that I'm trying to achieve.
What I have tried so far:
Using rewrites
Adding trailing slashes to both location path and proxy_pass
I know this can be solved by changing the app's base url or the build directory but that is not what I'm looking for.
Any help would be highly appreciated.

Nginx cache some location(static files) from another reverse proxy location

I have backend web-application working on 8081 port. It is Java spring boot application like uber-jar. So, static files placed into jar file. I have nginx as frontend. And I want to setting up cache static files on frontend. I thought what it is something like this:
proxy_cache_path /tmp levels=1:2 keys_zone=my_cache:10m max_size=10g
inactive=60m use_temp_path=off;
server {
listen 80;
server_name site.ru;
location /my_app {
proxy_pass http://127.0.0.1:8081;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location ~ /my_app/.+\.css {
proxy_pass http://127.0.0.1:8081;
proxy_cache my_cache;
proxy_cache_valid 200 1d;
}
}
... but it is not working. I believe what I on right way, though a little bit wrong

Node Application structure for subdomains

I am looking at building a website using node however my idea would be best with the use of subdomains. What i wanted to know is do i need to run each subdomain as a separate app and point to them with nginx?
Current Structure
- client
-- assets
--- js
--- css
--- img
- server
-- app
--- home
--- subapp1
--- subapp2
-- node_modules
-- server.js
-- config.js
The above structure is the thought that each app will run ny itself however they have common views that should be shared. Server.js will run them all. I just need to know if this is correct structure and if there is any cleaner or better alternative. Thanks
I'd suggest setting up Nginx to reverse proxy to 2 NodeJS apps. Run 1 app on port 8081 for example (service1) and the other on 8082 (service2) like this:
upstream service1 {
ip_hash;
server localhost:8081;
}
upstream service2 {
ip_hash;
server localhost:8082;
}
server {
listen 0.0.0.0:80;
server_name service1.mydomain.com;
location / {
index index.html index.htm;
proxy_pass http://service1;
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;
}
}
server {
listen 0.0.0.0:80;
server_name service2.mydomain.com;
location / {
index index.html index.htm;
proxy_pass http://service2;
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;
}
}

Multiple meteor applications using the same domain in digitalocean using nginx?

I'm trying to host 2 applications in the same droplet in digitalocean by using nginx
But so far I've only been able to get the root application running (the one without example.com/secondapp)
I want to be able to not use a subdomain and just use example.com/secondmeteorapp to be able to access it.
My sites-enabled/default looks like this:
server {
listen 80;
#listen 443 ssl;
server_name example.com/;
#ssl_certificate /etc/nginx/ssl/ssl-bundle-myApp-domain-com.crt;
#ssl_certificate_key /etc/nginx/ssl/myApp_domain_com.key;
location /dragonfire {
proxy_pass http://localhost:4000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forward-Proto http;
proxy_set_header X-Nginx-Proxy true;
proxy_redirect off;
}
location /images {
alias /home/dragonfire-build/bundle/programs/web.browser/assets/images;
access_log off;
expires max;
}
location /fonts {
alias /home/dragonfire-build/bundle/programs/web.browser/assets/images;
access_log off;
expires max;
}
location "^/[a-z0-9]{40}\.(css|js)$" {
root /home/dragonfire-build/bundle/programs/web.browser;
access_log off;
expires max;
}
}
however, when I access http://serverIpAddress/dragonfire it can't find the css or javascript giving me this error:
GET http://myipaddress/1f3848edee9e199050b9b1965b9e697aa714b9f3.css?meteor_css_resource=true
GET http://myipaddress/6e48198c6b584ff79c86e0c624a65b4853faaf50.js?meteor_js_resource=true 404 (Not Found)
I can access the app if I go directly through the IP address and port but not via the nginx way
QUESTION
How can I access a second app using the same domain but with a /mysecondapp (in this case /dragonfire at the end?

How do you serve static files from an nginx server acting as a reverse proxy for a nodejs server?

My current nginx config is this:
upstream nodejs {
server 127.0.0.1:3000;
}
server {
listen 8080;
server_name localhost;
root ~/workspace/test/app;
index index.html;
location / {
proxy_pass http://nodejs;
proxy_set_header Host $host ;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
I'm very very new to nginx, but at the very least I know that nginx is better than node/express at serving static files. How can I configure the server so that nginx serves the static files?
I solved it using this new configuration:
upstream nodejs {
server localhost:3000;
}
server {
listen 8080;
server_name localhost;
root ~/workspace/test/app;
location / {
try_files $uri #nodejs;
}
location #nodejs {
proxy_redirect off;
proxy_http_version 1.1;
proxy_pass http://nodejs;
proxy_set_header Host $host ;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
Thanks to the following Stack Overflow post:
How to serve all existing static files directly with NGINX, but proxy the rest to a backend server.
You'll probably want another location block within your server for the static files.
location /static {
alias /path/to/static/files;
}
This uses the alias directive.
Then you can hit files at localhost:8080/static/some_file.css
P.S. You don't need the root or index that you have set currently.
(root is similar to alias with a slight difference in usage)
