I'd look into something likeSupervisor.Very useful tutorial can be found herehttps://www.codingforentrepreneurs.com/blog/hello-linux-setup-gunicorn-and-supervisor/ | I want to make a Flask+Nginx+Gunicorn deployment. I have Nginx setup and running and I run gunicorn as described in the docs:gunicorn app:appBut when I logout of the server the gunicorn process exits? What is the correct way to make sure it stay running for Nginx to connect to, and restarts if it crashes? | What is the correct way to leave gunicorn running? |
Why is something like that useful? At first look I wasn't sure if it could be done. But it presented an interesting question.You might try putting a redirect statement in your config file and restarting your server. Two possibilities might happen:The server will issue the redirect - what you seem to want.The server will first do the https exchange, and THEN issue the redirect, in which case, what's the point?Will add more if I come up with something more concrete.UPDATE:(couple of hours later)You could try this. You need to put this in yournginx.conffile -server {
listen 443;
server_name _ *;
rewrite ^(.*) http://$host$1 permanent;
}Sends a permanent redirect to the client. I am assuming you are using port 443 (default) for https.server {
listen 80;
server_name _ *;
...
}Add this so that your normal http requests on port 80 are undisturbed.UPDATE:18th Dec 2016-server_name _should be used instead ofserver_name _ *in nginx versions > 0.6.25 (thanks to @Luca Steeb) | Is there a way to redirect HTTPS requests to HTTP by adding a rule in the domain's vhost file? | How do I redirect HTTPS to HTTP on NGINX? |
This behaviour is documented athttps://docs.docker.com/compose/extends/#adding-and-overriding-configurationFor the multi-value optionsports,expose,external_links,dns,dns_search, andtmpfs, Compose concatenates both sets of valuesSince theportswill be the concatenation of the ports in all your compose files, I would suggest creating a newdocker-compose.dev.ymlfile which contains your development port mappings, removing them from the basedocker-compose.ymlfile.AsNikson says, you can name thisdocker-compose.override.ymlto apply your development configuration automatically without chaining the docker-compose files.docker-compose.override.ymlwill not be applied if you manually specify another override file (e.g.docker-compose -f docker-compose.yml -f docker-compose.prod.yml) | My docker compose configs look like this:docker-compose.ymlversion: '3.5'

- 8080:8080docker-compose.prod.ymlversion: '3.5'

ports:
- 80:80Now, when I run command:docker-compose -f docker-compose.yml -f docker-compose.prod.yml upthe nginx exposes on host machine two ports:8000and80, because it merges ports properties:version: '3.5'

Uploading files is actually possible with AJAX these days. Yes, AJAX, not some crappy AJAX wannabes like swf or java.This example might help you out:https://webblocks.nl/tests/ajax/file-drag-drop.html(It also includes the drag/drop interface but that's easily ignored.)Basically what it comes down to is this:
(demo:http://jsfiddle.net/rudiedirkx/jzxmro8r/)So basically what it comes down to is this =)xhr.send(file);Wherefileis typeofBlob:http://www.w3.org/TR/FileAPI/Another (better IMO) way is to useFormData. This allows you to 1) name a file, like in a form and 2) send other stuff (files too), like in a form.var fd = new FormData;
fd.append('photo1', file);
fd.append('photo2', file2);
fd.append('other_data', 'foo bar');
xhr.send(fd);FormDatamakes the server code cleaner and more backward compatible (since the request now has the exact same format as normal forms).All of it is not experimental, but very modern. Chrome 8+ and Firefox 4+ know what to do, but I don't know about any others.This is how I handled the request (1 image per request) in PHP:if ( isset($_FILES['file']) ) {
$filename = basename($_FILES['file']['name']);
$error = true;
// Only upload if on my home win dev machine
if ( isset($_SERVER['WINDIR']) ) {
$path = 'uploads/'.$filename;
$error = !move_uploaded_file($_FILES['file']['tmp_name'], $path);
}
$rsp = array(
'error' => $error, // Used in JS
'filename' => $filename,
'filepath' => '/tests/uploads/' . $filename, // Web accessible
);
echo json_encode($rsp);
exit;
} | It seems like I have not clearly communicated my problem. I need to send a file (using AJAX) and I need to get the upload progress of the file using theNginx HttpUploadProgressModule. I need a good solution to this problem. I have tried with the jquery.uploadprogress plugin, but I am finding myself having to rewrite much of it to get it to work in all browsers and to send the file using AJAX.All I need is the code to do this and it needs to work in all major browsers (Chrome, Safari, FireFox, and IE).

To answer your question:in php-fpm.d/www.conf file:set the access.log entry:access.log = /var/log/$pool.access.logrestart php-fpm service.try to access your pagecat /var/log/www.access.log, you will see access logs like:- - 10/Nov/2016:19:02:11 +0000 "GET /app.php" 404

The documentation says:The default_server parameter, if present, will cause the server to become the default server for the specified address:port pair.It's also obvious, there can be only onedefaultserver.And it is also says:A listen directive can have several additional parameters specific to socket-related system calls.

According tonginxdocumentationthere is no syntax for NOT matching a regular expression. Instead, match the target regular expression and assign an empty block, then use location / to match anything elseSo you could define something likelocation ~ (dir1|file2\.php) {
# empty
}
location / {
rewrite ^/(.*) http://example.com/$1 permanent;
} | How do I set alocationcondition in Nginx that responds to anything that isn't equal to the listed locations?I tried:location !~/(dir1|file2\.php) {

Not quite enough info to say definitively, but based on the config you've provided, it looks like you have loop. You're proxying the requests to localhost:80, but NGINX is most likely listening on port 80. So, NGINX is connecting to itself over and over, hence the errors about too many open files.Also, Kibana doesn't have any server-side code, so proxy_pass isn't appropriate here. Something like the following should be enough:root /var/www/
location /kibana-3.1.2 {
try_files $uri $uri/ =404;
}With that being said, if you intend for this to be accessible from the public internet, you should protect it with a password and you should use proxy_pass in front of elasticsearch to control what requests can be made to it.

I think you may be confused, Flask is not aweb server, it is a framework and needs some sort of web server, such as Gunicorn, Nginx or Apache, to accept HTTP requests which it will then operate on. The reason why people run Nginx and Gunicorn together is that in addition to being a web server, Nginx can also proxy connections to Gunicorn which brings certain performance benefits, here is a pretty good answer that elaborates on those benefits:https://serverfault.com/questions/220046/why-is-setting-nginx-as-a-reverse-proxy-a-good-ideaEDIT:Added link containing information about performance benefits of running Nginx as a proxy. | This question already has answers here:Are a WSGI server and HTTP server required to serve a Flask app?(3 answers)Closed5 years ago.I see people are running setups like Nginx + Gunicorn + Flask.Can someone explain what is the benefit of having Gunicorn in front of Flask?

I had this same problem before. Because Nginx can't do complex conditions or nested if statements, you need to evaluate over 2 different expressions.set a variable to some binary value then enable if either condition is true in 2 different if statements:set $my_var 0;
if ($host = 'domain.example') {
set $my_var 1;
}
if ($host = 'domain2.example') {
set $my_var 1;
}
if ($my_var = 1) {
rewrite ^/(.*)$ http://www.domain.example/$1 permanent;
} | I want to redirect requests on two conditions using Nginx.This doesn't work:if ($host = 'domain.example' || $host = 'domain2.example'){

For nginx/mod_wsgi, ensure you read:http://blog.dscpl.com.au/2009/05/blocking-requests-and-nginx-version-of.htmlBecause of how nginx is an event driven system underneath, it has behavioural characteristics which are detrimental to blocking applications such as is the case with WSGI based applications. Worse case scenario is that with multiprocess nginx configuration, you can see user requests be blocked even though some nginx worker processes may be idle. Apache/mod_wsgi doesn't have this issue as Apache processes will only accept requests when it has the resources to actually handle the request. Apache/mod_wsgi will thus give more predictable and reliable behaviour. | What to use for a medium to large python WSGI application, Apache + mod_wsgi or Nginx + mod_wsgi?Which combination will need more memory and CPU time?Which one is faster?Which is known for being more stable than the other?I am also thinking to use CherryPy's WSGI server but I hear it's not very suitable for a very high-load application, what do you know about this?Note: I didn't use any Python Web Framework, I just wrote the whole thing from scratch.Note': Other suggestions are also welcome. | In production, Apache + mod_wsgi or Nginx + mod_wsgi? |
Reloading nginx is safer than restarting because before old process will be terminated, new configuration file is parsed and whole process is aborted if there are any problems with it.On the other hand when you restart nginx you might encounter situation in which nginx will stop, and won't start back again, because of syntax error.Reloading terminates the old process, so any memory leaks should be cleared anyway. | When is it necessary to restart nginx and reload will not suffice?Does it make a difference if an extension likepassengeris used?Should the service be restarted if it consumes too much memory.

I'd personally use Amazon's own repo.The version provided by the Amazon repo is relatively old (1.12.2at the time of writing). To see what versions the Amazon repo has access to runamazon-linux-extras list | grep nginxIf you'd like a later version, consider EPEL.In regards to the config, your best bet is to explicitly supply the configuration you require to the server.Using the off-the-peg ones are fine to get you up and running. However you run the risk of things changing when Nginx updates. Explicitly supplying your own configuration gives you greater control over what is running.Probably the simplest approach would be to upload the configuration generated bynginxconfig.ioto S3.Then add a script via user data when creating the EC2 instance to download your configuration.https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/user-data.htmlSomething like this...#!/bin/bash

You're not forwarding any information about whether this request was an HTTPS-terminated request or not. Normally, in a server, the "ssl on;" directive will set these headers, but you're using a combined block.Rack (and force_ssl) determines SSL by:If the request came in on port 443 (this is likely not being passed back to Unicorn from nginx)If ENV['HTTPS'] == "on"If the X-Forwarded-Proto header == "HTTPS"Seethe force_ssl sourcefor the full story.Since you're using a combined block, you want to use the third form. Try:proxy_set_header X-Forwarded-Proto $scheme;in your server or location blockper the nginx documentation.This will set the header to "http" when you come in on a port 80 request, and set it to "https" when you come in on a 443 request. | I want to have my API controller use SSL, so I added another listen directive to my nginx.confupstream unicorn {

Nginx uses theReactorpattern. Basically, it's single-threaded (but can fork several processes to utilize multiple cores). The main event loop waits for the OS to signal a readiness event - e.g. that data is available to read from a socket, at which point it is read into a buffer and processed. The single thread can very efficiently serve tens of thousands of simultaneous connections (the thread-per-connection model would fail at this because of the huge context-switching overhead, as well as the large memory consumption, as each thread needs its own stack). | I understand thread driven that Apache uses: every connection opens up a thread and when the response is sent, the thread is closed, releasing the resources for other threads).But I don't get the event driven design that Nginx uses. I've read some basics about event driven design .. but I don't understand how this is used by nginx to handle web requests.Where can i read and understand how Nginx is handling the connections in an event driven way so I get why it's better, rather than just accepting that event-based design is better than thread-driven design. | How does Nginx handle HTTP requests? |

I've recently stumbled upon this need myself and have found that in order to use variables in a proxy_pass destination you need to set a resolver as your error.log would most probably contain something likeno resolver defined to resolve ...The solution in my case was to setup the following using a local DNS for DNS resolution:location ~ /proxy/(.*) {
resolver 127.0.0.1 [::1];
proxy_pass http://$1;
}In your case this should work:location /proxy {
resolver 127.0.0.1 [::1];
set $target http://proxytarget.example.com;
proxy_pass $target;
}For resolver 127.0.0.1 to work, you need to install bind9 locally.

Nginx has some web server functionality (e.g., serving static pages; SSL handling) that gunicorn does not, whereas gunicorn implements WSGI (which nginx does not).... Wait, why do we need two servers? Think of Gunicorn as the
application web server that will be running behind nginx – the front-
facing web server. Gunicorn is WSGI-compatible. It can talk to other
applications that support WSGI, like Flask or Django.Source:https://realpython.com/blog/python/kickstarting-flask-on-ubuntu-setup-and-deployment/ | This question already has answers here:Are a WSGI server and HTTP server required to serve a Flask app?(3 answers)Closed5 years ago.I want to use gunicorn for a REST API application with Flask/Python.

error_pagehandles errors that are generated by nginx. By default, nginx will return whatever the proxy server returns regardless of http status code.What you're looking for isproxy_intercept_errorsThis directive decides if nginx will intercept responses with HTTP
status codes of 400 and higher.By default all responses will be sent as-is from the proxied server.If you set this to on then nginx will intercept status codes that are
explicitly handled by an error_page directive. Responses with status
codes that do not match an error_page directive will be sent as-is
from the proxied server. | I have a Sinatra application hosted with Unicorn, and nginx in front of it. When the Sinatra application errors out (returns 500), I'd like to serve a static page, rather than the default "Internal Server Error". I have the following nginx configuration:server {

After spending a lot of time on this, I finally figured it out. There are many references to Nginx and connection reset by peer. Most of them seemed to be related to PHP. I couldn't find an answer that was specific to Nginx and uwsgi.I finally found a reference to fastcgi and a 502 bad gateway error (https://support.plesk.com/hc/en-us/articles/213903705). That lead me to look for a buffer size limit in the uwsgi configuration which exists asbuffer-size. The default value is 4096. From the documentation, it says:If you plan to receive big requests with lots of headers you can increase this value up to 64k (65535).There are many ways to configure uwsgi, I happen to use a .ini file. So in my .ini file I tried:buffer-size=65535This fixed the problem. You can adjust that to taste. Maybe start with the max and work back until you have an acceptable value, or just leave it at the max.This was frustrating to track down because there was no error on the uwsgi side of things. | Environment is Nginx + uwsgi.Getting a 502 bad gateway error from Nginx on certain GET requests.

They aren't used in parallel. NGINX is areverse proxy. It's first in line. It accepts incoming connections and decides where they should go next. It also (usually) serves static media such as CSS, JS and images. It can also do other things such as encryption via SSL, caching etc.Gunicorn is the next layer and is anapplication server. NGINX sees that the incoming connection is forwww.domain.comand knows (via configuration files) that it should pass that connection onto Gunicorn. Gunicorn is aWSGIserver which is basically a:simple and universal interface between web servers and web applications or frameworksGunicorn's job is to manage and run the Django instance(s) (similar to usingdjango-admin runserverduring development)The contrast to this setup is to use Apache with themod_wsgimodule.

}

The problem is if you open a database connection when initializing your application, you then have multiple processes sharing the same connection, which causes the error above.The solution is to set thelazyconfiguration option for uwsgi, which forces a complete loading of the application in each process:lazySet lazy mode (load apps in workers instead of master).This option may have memory usage implications as Copy-on-Write semantics can not be used. When lazy is enabled, only workers will be reloaded by uWSGI’s reload signals; the master will remain alive. As such, uWSGI configuration changes are not picked up on reload by the master.There's also alazy-appsoption:lazy-appsLoad apps in each worker instead of the master.This option may have memory usage implications as Copy-on-Write semantics can not be used. Unlike lazy, this only affects the way applications are loaded, not master’s behavior on reload.This uwsgi configuration ended up working for me:[uwsgi]

Edit:As Alexey Ten didn't add a new answer, I'll edit mine to give his better answer in this case.if ($http_user_agent ~ "MSIE [67]\.")Original answer:Nginx doesn't allow multiple or nested if statements however you can do this :set $test 0;
if ($http_user_agent ~ "MSIE 6\.0") {
set $test 1;
}
if ($http_user_agent ~ "MSIE 7\.0") {
set $test 1;
}
if ($test = 1) {
rewrite ^ ${ROOT_ROOT}ancient/ last;
}It is not shorter but it allows you to do the check and put the rewrite rule only once.Alternative answer:In some cases, you can also use | (pipe)if ($http_user_agent ~ "(MSIE 6\.0)|(MSIE 7\.0)") {
rewrite ^ ${ROOT_ROOT}ancient/ last;
} | For example, I want to do this:if ($http_user_agent ~ "MSIE 6.0" || $http_user_agent ~ "MSIE 7.0" (etc, etc)) {

}instead of this:if ($http_user_agent ~ "MSIE 6.0") {
rewrite ^ ${ROOT_ROOT}ancient/ last;
break;
}
if ($http_user_agent ~ "MSIE 7.0") {
rewrite ^ ${ROOT_ROOT}ancient/ last;
break;

I think when you first set up nginx it comes with adefaultvirtual host. Did you try removing that? Did you try deleting the symlink?
A third option would be to add adeny all;on the location/of the default virtual host.I am not exactly sure if that will work and I cannot test it right now.

There is no way to (at least as of now). Full request will be always buffered before nginx will start sending it to an upstream.

It should be used with care though, see docs. | I configured nginx as reverse proxy to my node.js application for file uploads with proxy_pass directive.

I think the greatest benefit is that you're then able to use the same port (80) for multiple applications. Otherwise, you'd need a new IP address for each nodejs application you have. Depending on how you set things up, you can also configure different folders and subdomains to different nodejs apps running on different ports. If you're building something big or complex, this is pretty great. Imagine being able to run your APIs on one node application, your website from another, and the logged-in website (member's area, dashboard, etc.) in another app. Your load balancer can determine who needs to go where (example.com/api* -> api.js, example.com/dashboard* -> dashboard.js, example.com -> app.js). This is not only useful for scaling, but also when things break, not everything breaks at once.To the maturity thing, meh. Nodejs +forever+node-http-proxy= Amazing. Run 1 proxy server for all of your apps with a minimal config/complexity (lower chance of failure). Then have fun with everything else. Don't forget to firewall off your internal ports, though;).Some people make note of load balancing, which true, is a benefit. However, load balancing isn't something that most people will benefit from, since a single threaded, non-blocking nodejs thread can handle quite impressively large loads. I truly wouldn't even consider this as a difference if I were you. Load balancing is easy enough to implement when you need it, but otherwise utterly useless until you do.Also note, if you do go with a non-node proxy solution (nginx, tornado, etc.), just be sure NOT to use one that blocks.Apache blocks.Nginx doesn't. You don't want to throw away one of the greatest benefits of using nodejs in the first place on a crummy server. | What are the advantages of having nginx or another web-server running as a reverse-proxy in front of the Node.JS?

In most cases you don't need a custom module, you can simply set a
header with a combination of embedded variables of http_core_module
which is (most probably) unique. Example:location / {
proxy_pass http://upstream;
proxy_set_header X-Request-Id $pid-$msec-$remote_addr-$request_length;
}This would yield a request id like "31725-1406109429.299-127.0.0.1-1227"
and should be "unique enough" to serve as a trace id. | I'm using nginx as a load balancer in front of several upstream app servers and I want to set a trace id to use to correlate requests with the app server logs. What's the best way to do that in Nginx, is there a good 3rd party module for this?Otherwise a pretty simple way would be to base it off of timestamp (possibly plus a random number if that's not precise enough) and set it as an extra header on the request, but the only set_header command I see in the docs is for setting a response header. | Setting a trace id in nginx load balancer |
