Plex behind nginx reverse proxy with get requests to different route - nginx

I am trying to link all the services on my network together with nginx. One of those services is Plex. The nginx server is running inside docker on 192.168.1.150:80. The plex server is running on 192.168.1.149:32400. I also have a homer instance running on 192.168.1.148:80 I have a working config (see below), but I want to change something that I do not know how.
Nginx.conf:
user nginx;
worker_processes 5;
events {
worker_connections 2048;
}
http {
server {
location / {
proxy_pass http://192.168.1.148:80;
}
location /plex {
proxy_pass http://192.168.1.149:32400/web;
}
location /web {
proxy_pass http://192.168.1.149:32400/web;
}
}
}
As you can see, because plex requests resources from subdomain '/web', I have to add the proxy_pass for /web to go to plex as well. This is far from ideal when I want to use the subdomain /web for something else. The plex's index.html requests some script from /web/.... Is there some way to have this request go to /plex/web, so that I can catch it in that subdomain and not in the global one. This way I can use /web for something else.
Thanks in advance

Not sure if you found a solution but came across your post researching Plex configs and had the same question. This is what I came up with and works:
location /plex/ {
proxy_pass http://192.168.68.102:32400/;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
proxy_ssl_verify off;
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 86400;
}
if ($http_referer ~ /plex/) {
rewrite ^/web/(.*) /plex/web/$1? redirect;
}

Using reverse proxy to expose code-server to the internet

I have installed code-server on my Plesk VPS, and i was wondering how to expose it to the outside world using a reverse proxy.
Currently code-server is bound to 127.0.0.1:8080, and if i use wget via SSH i get the expected page.
How do i go about exposing code-server to the internet (using reverse proxy) on Plesk/CentOS
I’ve tried using vhost_nginx.config file but to no luck
location ~ / {
proxy_pass http://localhost:8080;
proxy_read_timeout 90;
}
You can try using my nginx config, change app URL and app port if needed, put it in /etc/nginx/sites-available than use symlink to /etc/nginx/sites-enabled, and don't forget to restart nginx.
server {
listen 80;
server_name example.com; #change app url
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_pass http://127.0.0.1:8080; #change app port
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
# location /overview {
# proxy_pass http://127.0.0.1:8080$request_uri; #change app port
# proxy_redirect off;
# }
}
}

How to rewrite url in nginx after matching the location

I am learning nginx, trying to setup an in-house server. My configuration is:
upstream app{
server app:8000;
}
server {
listen 80;
location /api/app/ {
proxy_pass http://app;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
}
I want to request nginx with localhost/api/app/admin, but my app can only respond to app:8000/admin. Hence, I want only admin/ to be passed to the application. I tried using rewrite, but was not able to get the desired result.

Proxy_pass to url NGINX with a Meteor Server

I have configured a meteor server and setup the nginx configuration. The route works however when configuring dynamic subdomains to point to a specific part of the web app it produces a 404 error on the browser when loading the meteor file.
I am attempting to direct all *.domain.com to http://localhost:3000/booking/
My configuration is:
server {
server_name *.domain.com;
listen 80;
location / {
proxy_pass http://localhost:3000/booking/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade; #for websockets
proxy_set_header Connection $connection_upgrade;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
}
}
The 404 occurs in the Meteor JS file.
If I remove the above nginx subdomain configuration and go to a subdomain it works perfectly, loading the route application. I assume I am missing something to load the application correctly.
The issue only occurs when I proxy_pass to a route within the URL <url>/booking
There are different ways of solving the issue.
1 - In case of 404 try a fallback option without booking in url
server {
server_name *.domain.com;
listen 80;
location / {
proxy_pass http://localhost:3000/booking/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade; #for websockets
proxy_set_header Connection $connection_upgrade;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
error_page 404 = #fallback;
}
location #fallback {
proxy_pass http://localhost:3000/$request_uri;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade; #for websockets
proxy_set_header Connection $connection_upgrade;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
}
}
2 - Have a separate block for js and css
server {
server_name *.domain.com;
listen 80;
location / {
proxy_pass http://localhost:3000/booking/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade; #for websockets
proxy_set_header Connection $connection_upgrade;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
}
location ~ \.(js|css|font)$ {
proxy_pass http://localhost:3000/$request_uri;
proxy_http_version 1.1;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
}
}
I have a similar setup, where I have configured different Meteor applications on several subdomains plus a static website on the domain root, all pointing interlly to different ports.
Here is my setup step by step.
Folder structure, location and proxy pass
First thing to think about is the folder strucutre. Depending on your subdomain's VHost-root directory there is a relative path to your subdomain's application folder.
Imagine the following setup:
/www (dir, usually under /var)
/domain (dir)
/websitexy (dir, a static website is deployed under this dir)
/subdomain (dir)
/books (dir, subdomain app is deployed under this dir)
For such a setup I made my nginx config to point to the app's location within the subdomain:
location /books {
I had a similar issue when first time starting my app. One thing I found out is, that my config worked, when setting proxy_pass on my private ip/port combination:
proxy_pass http://172.x.x.x:3000;
This also involves to remove the route name (/books) adter the port number on this entry. Now your proxy pass involves all routing within your subdomain.
Note on routing
Note, that there can be confusion about routing here. By setting the location property you set the routing on the nginx level (server's directory structure), which is why there is no route within your proxy pass.
Your application may have it's own internal routing defined. It is important, that you app's internal router retrieves all requests based from it's application ur root. This is why it is important to have the proxy pass not to include any path after the port number.
Websocket
I have read some articles on nginx and websocket connections. Basically my initial settings came from this article and looked like from this documentation article:
location /app {
proxy_pass 172.x.x.x;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
}
I also had to add a proxy_read_timeout and proxy_send_timeout because there was an issue with the websocket protocol otherwise:
By default, the connection will be closed if the proxied server does
not transmit any data within 60 seconds. This timeout can be increased
with the proxy_read_timeout directive
So I also set the timeout values:
proxy_read_timeout 36000s;
proxy_send_timeout 36000s;
proxy_set_header Connection "upgrade";
Read more on this here and here.
Summarizing my setup looks like the following (using your app credentials):
location /books {
proxy_pass http://172.x.x.x:3000;
proxy_http_version 1.1;
proxy_read_timeout 36000s;
proxy_send_timeout 36000s;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
}
So to solve your case, you may check on your vhost directory (the one where your app is deployed, see folder structure above) and change your location and proxy_pass setting accordingly.
If this is not working, you may need to add some more output of your errors, e.g. a excerpt of the log when attempt to connect.

proxy pass configuration in nginx

I am a front end developer and tried my hands in nginx configuration last time which is working fine. The below is the configuration:
server {
listen 80;
server_name localhost;
access_log /var/log/nginx/localhost.access.log;
location / {
#By default route to node.js running on localhost:9000 port
proxy_pass http://localhost:9000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
#currently only one server but will have to redirect to n hosts based on a parameter
location /hosts.json {
proxy_pass http://app-host.net:3000;
}
#currently only one server but will have to redirect to n hosts based on a parameter
location /hosts/ {
proxy_pass http://app-host.net:3000;
}
}
Now, I need to redirect to 4 different servers based on a parameter. ie if the city is Bangalore, I need to redirect to bangalore.corp.net:3000 and if the city is NewYork, then I need to redirect to newyork.corp.net:3000 and so on.
Here is somewhat I am expecting:
location /app1/hosts/ {
proxy_pass http://app1-host.net:3000;
}
#But the proxy pass should point to http://app1-host.net:3000/hosts and not http://app1-host.net:3000/app1/hosts
How can we handle such proxy pass in the nginx configuration file. Please let me know.
You have a URL of the form /app1/hosts/foo which should map to http://app1-host.net:3000/hosts/foo. The can be achieved by appending a URI in the proxy_pass directive, which will act like an alias.
location /app1/hosts/ {
proxy_pass http://app1-host.net:3000/hosts/;
}
See this document for details.

Tornado app in multiple nginx locations

I have 2 tornado applications and I am trying to use nginx as a proxy for them, but I need those applications to be served in the same address but different locations (Access app1 with URL http://myserver/app1, and app2 with URL http://myserver/app2).
My nginx configuration file /etc/nginx/conf.d/myserver.conf:
upstream app1 {
server 127.0.0.1:8081;
server 127.0.0.1:8082;
}
upstream app2 {
server 127.0.0.1:9081;
server 127.0.0.1:9082;
}
server {
listen 80;
access_log /var/log/nginx/myserver.access.log;
error_log /var/log/nginx/myserver.error.log;
location app1/static {
root /path/to/app1/;
if ($query_string) {
expires max;
}
}
location app2/static {
root /path/to/app2/;
if ($query_string) {
expires max;
}
}
location /app1/ {
proxy_pass_header Server;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_pass http://app1/;
}
location /app2/ {
proxy_pass_header Server;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_pass http://app2/;
}
}
When I access, for instance, app1 via tornado it works fine:
Via tornado: http://myserver:8081/ redirects to login http://myserver:8081/auth/login. Good.
Via nginx: http://myserver/app1 redirects to http://myserver/auth/login (it should redirect to http://myserver/app1/auth/login).
What is the correct nginx configuration to make it work?
This is controlled by the proxy_redirects setting. You've turned it off, so when the tornado server redirects to /auth/login that gets passed through as-is. You need to either make the tornado server aware of its urls as seen by the outside world (i.e. include /app1/ in all the routes and redirects even internally) or turn on proxy_redirects to have nginx remap them. I recommend the former, since proxy_redirects only works for redirects and you'll usually run into similar issues in other places (urls for static content, for submission, etc).
