The pattern you use requires the legacy DN, since it assumes the/to separate the RDNs. So (since nginx v1.11.6) the following works:map $ssl_client_s_dn_legacy $ssl_client_s_dn_cn {
default "";

Not specifically a fix for Angular/nginx, but a practice I often use is to append a query string parameter to the resource when you load it. For me, this is typically derived from version number of the .js file / application, e.g. using it as a seed for a RNGSo, instead of:useBonus points- in your Angular application, you can keep track of what version of the assets that you want to include, meaning that you can release new asset files without having clients immediately update to them if they have them in local cache (although note that new clients will get the new version regardless) | I'm using angular with i18n translations in json files like de.json and en.json.

You don't really need aStatefulSet, aDeploymentwill do since nginx is already being fronted by a gcloud TCP load balancer, if for any reason one of your nginx pods is down the gcloud load balancer will not forward traffic to it. Since you already have a gcloud load balancer you will have to use aNodePortServicetype and you will have to point your gcloud load balancer to all the nodes on your K8s cluster on that specific port.Note that yournginx.confwill have to know how to route to all the services internally in your K8s cluster. I recommend you set up annginx ingress controller, which will basically manage thenginx.conffor you through anIngressresource and you can also expose it as aLoadBalancerService type. | I have some services running in Kubernetes. I need an NGINX in front of them, to redirect traffic according to the URLs, handle SSL encryption and load balancing.There is a working nginx.conf for that scenario. What I´m missing is the right way to set up the architecture on gcloud.Is it correct to launch a StatefulSet with nginx and have a Loadbalancing Service expose NGINX? Do I understand it right, that gcloud LB would pass the configured Ports ( f.e. 80 + 443) to my NGINX service, where I can handle the rest and forward the traffic to the backend services? | NGINX loadbalancing on Kubernetes |

First you should comment out this line or remove this line from thesnippets/fastcgi-php.conffiletry_files $fastcgi_script_name =404;then on your virtualhost config puttry_files $uri $uri /index.php;before theinclude snippets/fastcgi-php.conf;on thelocation ~\.php$block.thelocation ~\.php$block should look like this:location ~ \.php$ {

The problem was that my client key was also including signing certificates in key chain.

Don't use django to deliver static content, specially not when it's static content that's as large as this. Nginx is ideal for delivering them. All you need to do is to create a mapping such as this in your nginx configuration file:location /static/ {
try_files $uri =404 ;
root /var/www/myapp/;
gzip on;
gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;}With/var/www/myapp/being the top level folder for your django app. Inside that you will have a folder namedstatic/into which you need to collect all your static files with the django manage.py 's collectstatic command.Of course you are free to rename these folders anyway you like and to use a different file structure all together.

I'm pretty sure you can't do this out-of-the-box with nginx. This feature is really designed for accelerating file downloads, so it's pretty focused on GET requests.That said, youmightbe able to do something fancy with the lua module. After you've compiled a version of nginx that includes the module, something like thismightwork.Ruby code:def proxy_video(path)
self.status = 200
response.headers["X-Accel-Redirect"] = "/proxy/#{path}"
response.headers["X-Accel-Post-Body"] = "var1=val1&var2=val2"
render text: 'ok'
endNginx config:location ~* ^/proxy/(.*?)/(.*) {

';
# Set download request headers
proxy_set_header Host $download_host;
# Do not touch local disks when proxying content to clients
proxy_max_temp_file_size 0;
# Stream the file back send to the browser
proxy_pass $download_url?$args;
} | I'm using rails 4 and I'm proxying a GET request to another server like this:def proxy_video(path)

endIn my nginx config, I have this:location ~* ^/proxy/(.*?)/(.*) {

Turns out that the server should be running on 0.0.0.0 if it needs to be reachable by addressing the IP of the instance.So to solve my problem, I stopped the server running resque on 127.0.0.1:3000 and restarted it to bind to 0.0.0.0:3000.

My bet is that the 5MB file is too large for Apache'smax_request_bodysetting (or whatever its name was), leading to the PHP script not being executed, thus never getting to send those headers, which in turns generates the misleading cross domain error.If this assumption is true, you should be seeing more details in your browser's "Net" tab - the upload script should be returning an error condition of some sort.To debug, you could do a normal form-based file upload, test that, and adjust things until it works. | So the point is I have a subdomain which is API endpoint for uploading files.

A CGI application is simply a standard executable or script - each HTTP request to the web server corresponds to a single execution / instance of that executable or script where environment variables are used to pass information about the request (such as the request URL and request method) and the HTTP request body is passed on the standard input. The script / executable the passes the rawHTTP outputthrough the standard output stream to the web server.For a example of a CGI application see thewikipedia pagefor an example perl script and for more detail have a read through of theCGI specificationFast CGI is an attempt to reduce the overhead of the CGI interface - as starting a new process is a relatively expensive task on many operating systems, Fast CGI attempts to reduce this by allowing a single long-running Fast CGI process to handle many HTTP requests.Although many parts of Fast CGI are similar to CGI (for example the format of the environment variables), with Fast CGIallinformation is passed through the standard input stream.You should try looking at theFast CGI websitefor more information - in particular the Fast CGI specification is on there and explains all of this in detail. | I want to understand how the webserver (for example: nginx) and cgi/fastcgi communicate with each other.

Looks like Nginx doesn’t think it’s talking HTTP/2 as the go client is sending the connection preface message ("PRI * HTTP/2.0") which Nginx thinks is a real message.The likely issue is that Nginx has not stated in the SSL/TLS handshake that it supports HTTP/2 via ALPN (or the older NPN). Which version of OpenSSL (or equivalent) was Nginx built with? Runnginx -Vto see this. Ideally you want 1.0.2 or above to support ALPN.Also check that your SSL/TLS cipher is not usingone of the ciphers forbidden for HTTP/2.

There are a few things here. To start, I don't think you're going to see much gain with running different types of requests in different processes. Your disconnect handlers are probably going to be very light - not doing much besides cleanup. Connect might not do much either and receive will get most of the load.You're betting off using the --threads parameter and starting multiple threads. Your current setup would only run one thread for each type of handler.The way runworker works is that it communicates with Daphne over your channel layer (ex Redis). All of the workers are listening to a queue. When a request comes in one worker will process it. While that worker is processing the request the other workers will wait for subsequent requests and process them. Once they send their response they go back to listening to the queue. If there are no --only-channels specified, each process will be pulling off requests and working on them as fast as it can and none of them will be waiting around.Its up to you to find the best balance of threads/workers by running multiple processes and the --threads parameter. You can also have workers reserved for heavy channels so they don't bring down your site.Having multiple Daphne instances will help. But since all they do is send messages between your server and the workers you might not see the benefit of running 4 of them.Everything stated here is not appliacable to Channels 2. This is for the old version of Django Channels. | I am usingdjango-channelsto addHTTP2&WebSocketsupport for my application. I could not find a lot of documentation as to how to scale channels.

This problem is indeed due to a bug inWerkzeug. As you noticed, this is now corrected since Jun 4, 2013 (cf. therelated commiton Github). You can have a bug free version of Werkzeug by using the version0.9.5instead of the0.9.4.Moreover, to troubleshoot your problem, I addedapp.debug = Truejust after the initialization of your Flask application.

Hence, I advise you to use it as follows:response.headers['WWW-Authenticate'] = 'Basic realm="test"'You can see some examples about this on theFlask documentationof the functionmake_response. | Adding headers with unicode_literals enabled seems to fail with Nginx, uWSGI and a simple Flask app:# -*- coding: utf-8 -*-

301 redirect is exactly what nginx shall do with that rewrite rule: because you put $scheme://$subdub at the replacement part, nginx will do a 301, ignoring that "break" flag.If the replacement string begins with http:// then the client will be redirected, and any further rewrite directives are terminated.Are you trying to "rewrite" or "redirect"? If it's just for rewrite, you can remove that rewrite directive:rewrite ^ $scheme://$subdub break;and it will work because your upstream server could rely on the HOST header to determine the traffic target (virtual hosting).Alsoyour host header sent to the upstream server is wrong. It should beproxy_set_header Host $subdub;$scheme should not be put in the Host header. | I want to achieve the following:Request Host:http://example.com.proxy.myserver.comShould be rewritten tohttp://example.comand passed to a squid server via nginx proxypass.server {

So, you probably won't be able to use Node.js on a typical 'hosted server'. These servers are typically running Apache and only support a limited set of languages.

Now, if someone is using nginx, they're probably using it as a load-balancer or to serve static content.If you don't understand how or why it's configured this way, you definitely need to talk to the project owners.

Will add another step to my pre-commit script to replace all direct links with links to versioned files in the minimized CSS.Seems there is no better way to do it. If you think of any, let me know and I'll consider marking that one as accepted answer.Thanks for your comments! | I am setting far-future expires headers for my CSS/Javascript so that the browsers don't ever ask for the files again once they get cached. I also have a simple versioning mechanism so that if the files change, the clients will know.Basically I have a template tag and I do something likewhich will become.The template tag opens a filejavascript/c/c.js.vwhere it finds the version number and appends it to the query string. The version is generated by a shell script (run manually for now, will probably add pre-commit hook) which checks whether the file has changed (usinggit diff).This is all working fine, EXCEPT:I want to implement the same kind of versioning for images as well. But images can be referenced from CSS - which is a static file (served by nginx) - so no template tag there.What is a better approach for file versioning?Alternatively, I am thinking about replacing the template tag with a middleware which changes all links before returning the response. That is better than the template tag, which can be mistakenly omitted. But still doesn't solve the issue of images referenced from CSS.Also, I'm aware that having the version as part of the query string might cause trouble with certain proxies not caching the file - so I consider making the version part of the filename - for examplejavascript/c/c.123456.js.Note: It looks like there is no way to solve this issue using Django (obviously - since I don't even serve the CSS through Django).

| I have a working web app served by nginx with cherrypy in the backend and ReactJS for the front-end.The app grew so I want to use react-router to provide quick access to pages with URLs.

The problem with your node benchmark is that you store the static file in a variable inside the V8 heap. Due to the way how V8 handles memory it can't directly send data contained in javascript variables to the network, because addresses of allocated objects may change during runtime, therefore V8 has to make a copy of your 1.8MB string on every request, sure that kills performance.What you could do is to use aBuffer:replace:longAssString = fs.readFileSync(pathToABigFile, 'utf8');with:longAssString = fs.readFileSync(pathToABigFile);that way you have your static file in a buffer, buffers are stored outside of V8s heap and require no copy when sent to the network and should therefore be much faster. | Take the same code that sits on nodejs.org home page.

Then you should use the default CloudFlare header that is included with every request that holds the client's IP named "CF-Connecting-IP".

It depends on your default configuration, but fromthis answer on ServerFaultyou must define a default vhost in Nginx, otherwise it will use the first one as a default.Basically, your configuration should look like this in order to allow only requests to "mywebsite.com.br" to pass:server {

# or show another site

The whole problem stems from trying to run nginx as my ordinary user self despite the fact that nginx was installed by my user self with administrative privileges. I was able to resolve both the errors shown here with the following commands executed as a user with administrative privileges:sudo chmod a+w /usr/local/var/log/nginx/*.log
sudo chmod a+w /usr/local/var
sudo chmod a+w /usr/local/var/runNote that the/usr/local/vardirectory appears to have been created by homebrew upon installing nginx and this machine is my laptop so I can’t see any reason not to open it up. You might have greater security concerns in other scenarios.I admit that when I wrote this question I thought it was about moving theerror.logfile to another directory. Now I see that that is not a full solution, so instead the solution I present here is about giving ordinary users write privileges in the necessary directories.The reason I changed my mind is that nginx can (and in this case does) generate errorsbefore(orwhile) reading thenginx.conffiles and needs to be able to report those errors to a log file. Modifying thenginx.conffile was never going to solve my problem.

Consider next setup:nginx -> ring server (jetty)You need to startlein ring server(usinglein-ringplugin) on some port (say 8080). Nginx will listen at 80 port and forward requests to 8080.
Here is a sample nginx config:upstream ring {
server 127.0.0.1:8080 fail_timeout=0;
}
server {
root ;
# Make site accessible from http://localhost/
server_name localhost;
location / {
# First attempt to serve request as file

}

proxy_set_header Host $http_host;
proxy_pass http://ring;
}
location ~ ^/(assets|images|javascripts|stylesheets|swfs|system)/ {
expires max;
add_header Cache-Control public;
}

Nginx defaults to considering underscores in request headers invalid and subsequently removes them, seehttp://wiki.nginx.org/HttpCoreModule#underscores_in_headersfor how to fix this. | I'm running Rails 3.1 with PhusionPassenger and NGINX in the back. I'm sending requests via a simple HttpClient (GrahpicalHttpClient for OS X). My code expects a token and an ID in the header to verify the authenticity of the caller. In developement mode this is no problem, but once I move it into production the header variables go missing. Nothing is displayed.Here is the code:@caller = Person.check_authentication_token(request.headers['person_id'], request.headers['authentication_token'])The method check_authentication_token returns nil if either variable is nil. As I said, this works fine in development but the request.headers['person_id'] and request.headers['authentication_token'] are both nil in production. Has anyone else seen this issue before? | header variables go missing in production |
The default capacity is 100 messages and the default message expiration time is
60 seconds. So if the the channel is never read within these capacity / time
constraints, it will fill up.One reason why a channel might fill up is when the connection is never properly
closed. In this case the channel will remain in the group and eventually fill up.One way to mitigate this is to have enough capacity and a short timeout. You
can alter the configuration in the Django settings in the following way:CHANNEL_LAYERS = {
"default": {
"BACKEND": "channels_redis.core.RedisChannelLayer",
"CONFIG": {
"hosts": REDIS_URL, # or where your redis server lives
"capacity": 1500, # default 100
"expiry": 10, # default 60
}
}

Indeed, when you are enabling Jelastic SSL (means you can't use public IP) shared resolvers processing all requests to your server but between resolver and your server requests are not https.

Typically, you dedicate a container for authentication, with for instance NGiNX.This is described in "Authenticating proxy with nginx", which not only adds the basic authentication, but also ssl (https)That web server will then reverse proxy to your container.You have a more generic solution (based on a reverse-proxy NGiNX) withjwilder/nginx-proxynginx-proxy sets up a container running nginx anddocker-gen.docker-gengenerates reverse proxy configs for nginx and reloads nginx when containers are started and stopped.See the use case with "Automated Nginx Reverse Proxy for Docker". | Consider running a Docker container with a web application exposing a certain port.

Martin,In general, Nginx is better for high-traffic sites due to its event-driven architecture. Rather than handling each request in a distinct thread, it uses non-blocking I/O to service many requests in each thread.The important aspect of this architecture is the reduced use of processes or threads. A thread can consume anywhere from 2MB to over 64MB of RAM. So when Apache serves a 10KB JPEG, it may actually be using a significant amount of RAM. It becomes worse if you have slow clients (e.g. smartphones) where the request may keep a thread busy for several seconds.Many people find that running Nginx as a proxy in front of Apache to be an ideal middle ground. Nginx talks to the slow clients and can do so using a very small amount of RAM. When requests are forwarded to Apache, the request speed is limited by your local connectivity, not that of the remote user. This means that the network bottleneck will not keep the request (and it's memory-hogging thread) alive for any longer than necessary.In short you get the low-resource benefits of Nginx coupled with the wide feature-set of Apache. | Wouldnginxbe a more suitable choice as a web server for high traffic websites?The site we will be building is an e-commerce site, if that makes a difference.I am really interested in the actual 'why' from a technical point of view either way. i.e., why wouldnginxbe a better choice for this type of site from a technical standpoint, or the opposite, why it wouldn't? | Nginx v Apache for high traffic sites |
Fromthe Django docs:DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone through security audits or performance tests. (And that's how it's gonna stay. We're in the business of making Web frameworks, not Web servers, so improving this server to be able to handle a production environment is outside the scope of Django.)So, that answers the latter two questions. As for the former, it depends on how your debug server is set up. If your server is exposed to the public Internet, doesn't have a firewall blocking port 8000, and you intend to userunserverwith something other than the default 127.0.0.1 address, set up a more 'proper' application stack.If you're going to use nginx, why not just use thesuggested FastCGI configurationso that your debug environment will be more similar to the future production environment? | Concerning the built in debugging server started with themanage.py runservercommand, the Django docs state, "DON’T use this server in anything resembling a production environment."If I wanted to develop a Django application over ssh on a remote machine, would using Nginx as a proxy to a running Django debug server be a reasonable thing to do?

Thenginxsetting you are trying to use (/etc/nginx/conf.d/proxy.conf) is forAmazon Linux 1.Since you are usingAmazon Linux 2you should be using different files for setting nginx. For AL2, the nginx settings should be in.platform/nginx/conf.d/, not in.ebextentionsas shown in thedocs.Therefore, you could have the following.platform/nginx/conf.d/myconfig.confwith content:client_max_body_size 20M;The above isan exampleonly of the config file. I can't verify if the setting will actually work, but you are definitely using wrong folders to set nginx options.My recommendation would be to try to make it work manually through ssh as you are attempting now. You may find that you need to overwrite entire nginx setting if nothing works by providing your own.platform/nginx/nginx.conffile. | I have a Node 10 app running on Elastic Beanstalk, and it throws 413 errors when the request payload is larger than ~1MB.

/etc/nginx/nginx.confis not the place to store your server setups. This file should contain information on the user it will run under and other global settings. Typically it will contain stuff like this:user www-data;

I think the best option is to use a suite of Logstash (event collecting) + Elasticsearch (event storage) + Kibana (analytics). All three are really good opensource projects with a lot of documentation and very active communities.And if you need commercial support for any you can request help from:http://www.elasticsearch.org/Logstash its flexible enough to allow you parse many log file formats out of the box. Moreover, storing all your logs on elastic search will allow you to create custom queries, reports and stuff.You can check a kibana demo on:http://demo.kibana.org/Links:http://www.elasticsearch.org/overview/kibana/http://logstash.net/ | I develop and maintain a paywalled publication with 2000+ users. The most common support request relates to log in. Most times these can be solved with a couple of support emails. Every once in a while though, there's that odd user that just can't log in. As a last resort the support person resets the users password, verify that they can log in themselves and send the new credentials of to the user. Every now and then we get at user that still can not log in. At that point I'm out of troubleshooting tools.So I'd like to have a tool that:Logs all HTTP requests in full (except for users passwords).Let's me search the log for a POST request to my login page containing the users name.Let me look at all requests from the IP-address that I found in step 2 within a certain timeframe, and then analyse those requests very closely.And I need to be able to do smart log rotation, like: "Hang on to everything you can fit into 30 GB, then start throwing out the old stuff".Our publication happens to be built with Django and nginx, but I don't think that the tool I'm looking for will be specific to those tools. And I definitely don't want to throw all the request data in the same SQL database as my Django app.So far I've foundLogstash, but I haven't look at it closely enough to know if it's right for me. The important thing to me isn't to get nice graph of all usage, user trends, conversion funnels etc. What I need is better ways to troubleshoot a problem that's affecting a single user. | How to do HTTP request logging as a means of troubleshooting login errors |

The Docker way to do this would be to have two containers for the two services. Docker-compose is a tool that helps manage multi-container applications.The following docker-compose.yml should work for you:version: '3'
services:
app:
build:
context: ./dotnet
dockerfile: Dockerfile
expose:
- "80"
proxy:
build:
context: ./nginx
dockerfile: Dockerfile
ports:
- "80:80"
links:
- appBasically we expose the port for your app so the Nginx container can access it, and then we bind the port on the Nginx container to the one on your host machine.You put your Dockerfile and app in the "dotnet" folder, and your NginX logic in the /nginx/Dockerfile file.EDIT: If you would really like to have both services in a single container you can use the following:FROM microsoft/dotnet:2.1-aspnetcore-runtime

apt install nginx

RUN service nginx restart

EXPOSE 80

You probably still have the default.conf still in the directory that nginx is using to serve up the sites. either that or check in nginx.conf. Somewhere there is a server setup already using 80 that is being served first. | I am using a DigitalOcean VPS hosting a meteor app. I don't have a domain name yet, so just use the plain IP address. When I set below config and usemyipaddress:3000andmyipaddress:8080, both of them worked well; but if I change the 8080 to 80, onlymyipaddress:3000works. Using onlymyipaddressormyipaddress:80will show "Welcome to nginx on Debian!" message. (I use Ubuntu 14.04 on the VPS).server {
listen 8080;
server_name default;
location / {
proxy_pass http://localhost:3000;
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;
}
}Can not figure out why can't use port 80.---- Solved this problem --------I commented out the "listen 80 default_server" in the /etc/nginx/sites-enabled/default" file, then my config at "/etc/nginx/conf.d/mysite.conf" works on port 80. | Nginx proxy_pass doesn't work on port 80 |
You could useGeo module. Your configuration then would look somewhat like this:geo $upstream {
default default_upstream;
10.50.0.0/16 some_upstream;
10.51.0.0/16 another_upstream;
}
upstream default_upstream {
server 192.168.0.1:80;
}
upstream some_upstream {
server 192.168.0.2:80;
}
upstream another_upstream {
server 192.168.0.3:80;
}
server {
...
location ... {
...
proxy_pass http://$upstream;
}
...
} | I've got a case where I need to do a different proxy pass in Nginx depending on which CIDR the client's IP address is part of.So, for example, let's say I have the following CIDRs:10.50.0.0/16

10.52.0.0/16Each of those client addresses needs to have a different proxy_pass in Nginx. How would I go about doing this? I'm very new to Nginx so achieving things like this are still a bit confusing. | Nginx - Different proxy pass based on IP ranges |

You may need to look at the proxy timeout configs in nginx if using nginx as a proxy:http://www.nginxtips.com/504-gateway-time-out-using-nginx/http://wiki.nginx.org/HttpProxyModuleproxy_connect_timeout 60;
proxy_read_timeout 120;Apigee timeout defaults:Connect timeout - 60s -connect.timeout.millisRead timeout - 120s -io.timeout.millisFYI Apigee timeouts are also configurable (in milliseconds) within the TargetEndpoint connection:
5000
5000
http://www.google.com
Depending on how long the server takes to respond can determine your ideal timeout configurations. In this case, a read timeout of 45-60s might be ideal to provide some buffer in case cloudstack slows down more. | I have a nodejs program that connects to cloudstack apis. Creating a Virtual Machine on cloudstack takes almost 20 secs.The program works fine on my local nodejs installation and also on apigee cloud. However when I deploy the same on customer's OPDK, Nginx returns a 502 - Bad gateway.

...

fastcgi_buffer_size 32k;
fastcgi_connect_timeout 300;

If the url does not belong to any paths that you registered viaapp.get(/...(or POST etc.) methods, Express sends the file if the static path is set and the path that you give belongs to some files path under static files directory. File sending is nothing more thanstreams, they do not block the event queue completely, they are just pushed to the queue and as chunks recieved, they are piped to the HTTP connection, so they happen on the background of your code. The reason of suggesting nginx is that it is more fit to that job, serving files and routing, and it is also written in C, and optimized for that job, where the NodeJS is a more general-purpose tool compared to Nginx. | I thought serving static files (html, mov, css, jpg, etc.) with Express was going to require some hacks in nginx.But it seems that static files "just work" with Express. No special thing is required.How does Express static file serving really work?Why do some people advocate using nginx for static files? There must be a good reason for this. (Example:https://gist.github.com/joemccann/644282)Also, while a static file is downloading, does the Node.js event queue get blocked? I suppose not, but why not? | Express.js (Node.js): How does static file serving really work? |
You will need to build your Java service in its own app server -- Tomcat would be a good choice for this. From there, it's a simple matter of configuringnginxto act as a proxy to Tomcat. Yournginxconfiguration will look something like the following:user www-data;
worker_processes 4;
pid /var/run/nginx.pid;
events {
worker_connections 4096;
# multi_accept on;
}
http {
server {
listen 80; #incoming port for nginx
server_name localhost;
location / {
proxy_pass http://127.0.0.1:8080;
}
}
#...and other things, like basic settings, logging, mail, etc.The important piece here is the setting forproxy_pass. That's tellingnginxto accept requests on port 80 and redirect them to port 8080 (Tomcat's standard port). | I am a really beginner on this topic, I need some helpful articles and your guidance.
