Nginx fastcgi multiplexing?

I'm in process of implementation of a fastcgi application, after reading fastCGI spec I've found a feature called "request multiplexing". It reminded me Adobe RTMP multiplexing back in the days that protocol was proprietary and closed. As far as I understand, multiplexing allows to reduce overhead of creating new connections to FCGI clients effectively interweaving requests chunks, and at the same time enabling "keep-alive" model to connection. Latter allows sending several requests over a sin

Nginx serving a directory as an alias

Proxying Jenkins with nginx

I'd like to proxy Jenkins using nginx. I already have a working version of this using this configuration file in /etc/sites-available/jenkins: server { listen 80; listen [::]:80 default ipv6only=on; location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_pass; } } However, what I'd like to do is host Jenkins at a relative url, like /jenkins/.

Non-www to www domain using Nginx on Ubuntu 12.04 LTS on Ec2 instance

After seeing this post I changed my server from apache2 to nginx. I am no computer geek just, savvy. I followed the steps. After that, the site was perfect, except for one thing: non-www to www thing. I searched all over the net on how to do this. I tried the modrewrite thing they said but just getting worst. For now, it is directed to www because I use wordpress and set it in general settings http://www.pag

Why does this dynamic Nginx proxy configuration not work?

I have a nginx configuration that looks like this: location /textproxy { proxy_pass http://$arg_url; proxy_connect_timeout 1s; proxy_redirect off; proxy_hide_header Content-Type; proxy_hide_header Content-Disposition; add_header Content-Type "text/plain"; proxy_set_header Host $host; } The idea is that this proxies to a remote url, and rewrites the content header to be text/plain. For example I would call: http://nx/textproxy?url=http://foo:50070/a/b/c?arg=abc:123 And it wou

Nginx Relative paths for assets in Play Framework

I'm running two Play 2.3.x applications behind nginx. In nginx, application A is configured to be accessed at "/". Application B is configured to be accessed at "/appB/". I'm having some problems resolving assets for application B when using the built in routes/assets functionality (<script src=""someScriptfile.js")") type="text/javascript"></script>. The problem here is that the URL will be absolute, for example /assets/file.png. This will result in that the prox

Nginx Proxy a rtmp stream

How could I proxy a rtmp stream? I have two raspberry pi streaming live video from raspicams on my LAN. Each raspberry pi sends the video to ffmpeg which wraps in flv and sends to crtmpserver. A third server using nginx, has a static html page with two instances of jwplayer, each pointing to one raspberry pi. The setup is just like this one. The web server uses authentication and I'd like streams not to be public too. I'm thinking of trying nginx-rtmp-module, but I am not sure if it wo

Optimize Ubunto and nginx to handle static files

I am experimenting with nginx (first time) to serve static files (400 kb). I have installed ubuntu 14.4 on linode servers (2gb ram, 2 core 3tb transfer) and nginx. Open files are set to 9000 , gzip is on, processes =2, worker connections 4000 Using jmeter at 50 users and 10 sec ramp up I am achieving 800 ms sample times and cpu and mem obviously are not a factor, 100 users, this increases to 5/6 seconds, the transfer out speed should be 250 mbps which explains that. But is there optimization

conditional rewrite or try_files with NGINX?

I'm having trouble setting up a conditional rewrite, and I've been trying to use the if directive (despite all sources indicating it's "evil") with the -f switch to check for the presence of a file, but it's not working. I believe the issue/case is best explained by example, so here goes: Directory structure workspace/ myapp/ webroot/ index.php assets/ baz.js hello/ foo.js modules/ hello/ assets/ foo.js bar.js

Where is nginx configuration in centos?

Nginx HHVM timing out due to large queue

I have HHVM setup using TCP upstreams and nginx. Currently there is one app doing two Guzzle Curl requests to two other apps on the same server. Eventually HHVM just starts to queue all of the requests and then stops responding. It does not give any errors, and its status is still running. The admin side is also still running. It is not consistent when it will decide to start queuing all of the requests.

Nginx rewrite not working (Kirby CMS Cachebuster)

Nginx shall rewrite /assets/css/main.1448958665.css to /assets/css/main.css. But trying to get that file, it returns a 404.

How can I use nginx rewrite with try_files to get react router working?

I am using the try_files directive with nginx and react to force all paths to go to /index.html and be handled by the react router so that the paths don't need to be prefaced with /#/. This works for that: location / { try_files $uri /index.html; } So a url like /invitation will go to the right place. However, there are still some sources that are generating /#/ urls and I would like to have them rewritten to the equivalent urls without the /#/ (so /#/invitation would go to /invitation)

How to change the nginx process user of the official docker image nginx?

I'm using Docker Hub's official nginx image: The user of nginx (as defined in /etc/nginx/nginx.conf) is nginx. Is there a way to make nginx run as www-data without having to extend the docker image? The reason for this is, I have a shared volume, that is used by multiple containers - php-fpm that I'm running as www-data and nginx. The owner of the files/directories in the shared volume is www-data:www-data and nginx has trouble accessing that - errors similar to

Nginx returns 502 if service not ready on start

It has these components: Node.js on port 3000 FFmpeg / FFserver on port 8090 Nginx in front to proxy these services together over ports 80/443 (HTTP/HTTPS) The problem that I am having is that if FFserver is not fully ready on port 8090 when Nginx starts up it will continually return a 502 for stream.mjpeg, even though the stream is running. It's as if Nginx determines that the host does not exist and then never tries again. Once I restart

The last & break mechanism in nginx rewrite

nginx reverse HTTP proxy - what behavior when all upstreams are unavailable?

In trying to measure and increase our nginx throughput, I noticed that there might be a problem with our configuration, but I'm not sure how to test for it. We use a simple upstream config, somewhat like this: upstream myapp1 { server max_fails=1 fail_timeout=3s; server max_fails=1 fail_timeout=3s; server max_fails=1 fail_timeout=3s; } When our backends become overloaded, the first upstream may enter unavailable state, and the ad

Nginx configuration always takes default block

I'm setting up a nginx for mutiple (3) domains. As i understood, the server should take the correct server block, when the server_name matches. In my case i always end up in the default block.

Here is my config: server { listen *:80 default_server; listen *:443 default_server; server_name _; return 444; } server { root /app/app-cluster/public; index index.php; server_name;

Nginx will not start with host not found in upstream

Stop nginx from decoding URL

I run an nginx server which serves static files. Some filenames contain strings like %3a. /var/www/testfile%3a If I try to request those files, I get a 404 Not Found error. This seems to happen because nginx decodes the URL and replaces %3a with :, and then does not find a file named /var/www/testfile:. I infered this from the following debug output from nginx: 2018/06/21 10:03:21 [debug] 32523#0: *6 http process request line 2018/06/21 10:03:21 [debug] 32523#0: *6 http request line: "GET

Nginx Reverse Proxy WebSocket Timeout

I'm using java-websocket for my websocket needs, inside a wowza application, and using nginx for ssl, proxying the requests to java. The problem is that the connection seems to be cut after exactly 1 hour, server-side. The client-side doesn't even know that it was disconnected for quite some time. I don't want to just adjust the timeout on nginx, I want to understand why the connection is being terminated, as the socket is functioning as usual until it isn't. EDIT: Forgot to post the configura

Nginx How do I preserve the requested port when using proxy pass?

Nginx From inside of a Docker container, how do I connect to the localhost of the machine?

So I have a Nginx running inside a docker container, I have a mysql running on localhost, I want to connect to the MySql from within my Nginx.
