There are two solutions for this
1- add the ssl certs to the loadbalance: You need to request a cert with all the supported DNS names (app.mydomain.com and design.customerwebsite.com)/ and you need to manage customerwebsite.com domain with Route53. I think that is not possible in your case.2- Do not use ssl on the load balancer: for this option, we will not terminate ssl on the load balancer, however, it will be passed to nginx to handle. Your loadbalancer configs should look likeyou need to generate a new ssl cert that includes both domainssudo certbot --nginx -n --redirect -d app.mydomain.com -d *.mydomain.com -d design.customerwebsite.com -d *.customerwebsite.comNginx configsserver

Yes, you can use multiple domains (each with its own SSL certificate) in nginx. You will need a separate server block for each domain in the nginx configuration file.

Ok after many days and hours breaking my head I came to this solution:On GoDaddy's DNS I added these records:A: test24.company.io -> A: sub1.test24.company.io -> A: sub2.test24.company.io -> note:All 3 records point to the same elastic IP, there is no need to set an individual elastic IP for each subdomain.The nginx conf file is configured as follows:https://gist.github.com/ahmed-abdelazim/b3536c1780afc4215ef57633bbe77a88Thispost is a very useful guide on setting nginx proxies for different ports on your server.All the rest in the nginx config file is generated by certbot, which also managed the redirect from http to https.note to mods: I cannot seem to format the code of the GitHubGist in this answer for some reason. | I'm trying to configuredefault.confin/etc/nginx/conf.dto show a simple landing page located at/home/ubuntu/project-source/company/entry/index.html.The domains are set up correctly as far as I know to point to the serverA: test24.company.io -> default.conf:server {

I have now found two solutions for the above...I have opted forsolution twoas it requires no code changes but have successfully tested both solutionsSolution OneApologies, I dont have access to the working test code on this machine but it goes something like the below :Create a base controller and override the ControllerBase.RedirectToAction method.Add a base URL setting to your webconfig (or a db setting etc).Create custom redirect result object and append baseurl to URL. Return custom result object from overridden method.protected override RedirectToRouteResult RedirectToAction(string actionName, string controllerName, RouteValueDictionary routeValues)Solution TwoUsing IIS, run the application within a virtual directory(s) or child application to match the location of the proxy. MVC will then automatically correctly control all the routing without having to override any base methods.NB. You will need be careful with any relative paths/links as with any proxy.I am currently using this method in production without any problems. See below example. | I am currently working on a project that requires one of our current ASP.NET MVC5 web applications to sit behind a NGINX reverse proxy that the client will control.I am brand new to NGINX so am lacking in knowledge.The reverse proxy will be placed at a sub path. (example below)http://localhost:9999/foo/bar/This will then proxy to the root of the MVC5 application (port 9998) I have set up NGINX locally to test that the site will work as expected. We use absolute paths to our resources (hosted in an internal CDN) so all these load as expected.My Issue- The reverse proxy is working correctly and displaying the root page of the application. The problems start to arise when hitting any controller methods/page links that have been created using this.RedirectToAction() or @html.ActionLink() etc.The MVC application does not realise it is running behind a reverse proxy and chops that subpath out of its derived URL.So a redirect to a home controller looks likehttp://localhost:9999/homeInstead of :http://localhost:9999/foo/bar/homeDoes anyone have any ideas the counteract this? I can see .NET core has a workaround but cant see anything for MVC5. I can use this.Redirect() and specify the absolute path but the application is large and used in other scenarios without the reverse proxy.Can this be resolved through my NGINX configuration? I have included my config below :#user nobody;

}

I finally found the cause of this problem. Nginx works correctly, however I routed requests to AWS Elastic Beanstalk which uses nginx internally to route requests to inside Docker container.So the misconfiguration was on the side of AWS Elastic Beanstalk. Configuring the AWS fixed the problem. | When I setclient_max_body_size 30m;without ssl everything works (files up to 30MB are accepted).

I think it is similar to Node solution - you should repeat all your routes in nginx config to return 404 status code correctly, the main idea is that you should use "equals" modifier in locations and defineerror_pageto return sameindex.htmlfile but with 404 status code, example:server {
listen 80;
server_name localhost;
root /my/dir/with/app
error_page 404 /index.html;
location = / {
try_files $uri $uri/ /index.html;
}
location = /books {
try_files $uri $uri/ /index.html;
}
# example nested page
location = /books/authors {
try_files $uri $uri/ /index.html;
}
# example dynamic route to access book by id
location ~ /books/\d+$ {
try_files $uri $uri/ /index.html;
}

Like elektronaut indicated, this is probably something that should be handled in your proxy's configuration. That said, ActiveSupport::UrlFor#url_for has some information that might be useful. Take a look athttp://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/routing/url_for.rbWhat I think it boils down to is passing two arguments into your url_for and/or link_to calls. First is the:port => 123argument, the second is:only_path => falseso that it generates the full link including domain, port, etc.So when generating a link, you might do:link_to 'test', root_url(:port => 80, :only_path => false)and when creating a custom url you might do:url_for :controller => 'test', :action => 'index', :port => 80, :only_path => falseFor a redirect:redirect_to root_url(:port => 80, :only_path => false)I hope this helps, and if it doesn't, can you be more specific about how you generating your URLs, what rails is generating for you, and what you would like it to generate.Update:I wasn't aware of this, but it seems you can set defaults for the URL's rails generates with url_for, which is used by everything else that generates links and/or URLs. There is a good write up about it here:http://lucastej.blogspot.com/2008/01/ruby-on-rails-how-to-set-urlfor.htmlOr to sum it up for you:Add this to yourapplication_controler.rbdef default_url_options(options)
{ :only_path => false, :port => 80 }
endand this:helper_method :url_forThe first block sets defaults in the controllers, the second causes the url_for helper to use the one found in the controllers, so the defaults apply to that as well. | I have an Rails application server that is listening on port 9000, and is being called through haproxy.

I can answer my own question (after several hours of looking in completely the wrong place). A good readup onAuthlogic::Session::Configdid the trick.class UserSession < Authlogic::Session::Base
allow_http_basic_auth false
end | I am in the early stages of building an app using Rails 3. User authentication is powered by Authlogic which I have setup pretty much as standard (as per the example docs) and everything is working as expected locally.I have just deployed the app to a clean server install of Centos 5.4 / NginX / Passenger so staff can start to log in and enter content, etc. However, we're a long way from this being ready for public eyes so I have used NginX's basic auth module to keep the entire site behind another level of authentication.Unfortunately Authlogic's authentication and NginX's basic authentication seem to be conflicting with one another. If basic auth is on then it is impossible to log in with Authlogic, yet if I disable basic auth then Authlogic works as expected.I haven't posted any code as I'm really not sure what code would be relevant.

First of all, not all variables need to be specified using environment variables. Keep variables that do not differ per system in a separate yaml file.When you have just one environment per server you can specify the environment variables globally in/etc/environment. (Might be different depending on your Linux flavour)Personally I find that using DotEnv poses more difficulties than solutions when you run multiple environments on the same server. Specifying the variables in a global configuration like/etc/environmentdoesn't work in that case.Specifying the environment variables in nginx isn't a solution either since, as you mentioned, they won't be picked up by cron, supervisor, the console, etc. For me, this was the reason to completely remove DotEnv and work with the good oldparameters.yamlfile again. Nothing will stop you from doing that.Another solution however is to keep using DotEnv in your development environment and to include a separateparameters.yamlin production. You can then define the environment variables as follows:parameters:
env(APP_ENV): prod
env(APP_SECRET): 3d05afda019ed4e3faaf936e3ce393ba
...A way to include this file is to put the following in your services.yaml file:imports:
- { resource: parameters.yaml, ignore_errors: true }This way, the import will be ignored when no parameters.yaml file exists. Another solution is to add a line toconfigureContainer()in your Kernel class:$loader->load($confDir.'/parameters'.self::CONFIG_EXTS, 'glob'); | .env files are very handy with docker, kubernetes, etcBut what if I have simple nginx server without any orchestration and a pack of cron workers and a pack of daemons(systemd/supervisord/etc)?I can write these env variables to nginx server section, but I have to set up hundreds of env variables to each cron worker or daemon.I found a quick solution: using symfony/dotenv component in production.But it seems to me dirty. Who can suggest better solution? | Symfony 4, .env files and production |

Emperor mode is for handling multi-application environments.

This is what worked for me:sudo cp /usr/local/opt/nginx/*.plist /Library/LaunchDaemons
sudo launchctl load -w /Library/LaunchDaemons/homebrew.mxcl.nginx.plistThe trick to this is that Mac OSX won’t let anything other than “root”
or “system” level services use a port number below 1024.Read more here:http://derickbailey.com/2014/12/27/how-to-start-nginx-on-port-80-at-mac-osx-boot-up-log-in/ | I installed NGINX with homebrew then I got info and followed the instructions to load the launchd plist$ brew info nginx

It turns out that the webdav module in-built in nginx is broken and to enable full webdav, we need to add the following external 3rd party module: nginx-dav-ext-module.Link to its github:https://github.com/arut/nginx-dav-ext-module.gitThe configure parameter would now be:./configure --with-http_dav_module --add-module=/path/to/the/above/moduleThe built in one just provides thePUT DELETE MKCOL COPY MOVEdav methods.The nginx-dav-ext-module adds the following additional dav methods:PROPFIND OPTIONSYou will also need to edit the configuration file to add the following line:dav_ext_methods PROPFIND OPTIONS;After doing so check if the syntax of the conf file is intact by issuing:nginx -tand then soft reload (gracefully) nginx:nginx -s reloadAnd Voila! you should now be able to use cadaver or any other dav client program to get into the directories.I cannot believe that I solved this, it drove me nuts for a while! | I have built nginx on a freebsd system with the following configuration parameters:./configure ... –with-http_dav_moduleNow this is my configuration file:user www www;

First, remove the forwarding and you need to change the nameservers of the domain in your domain DNS management if your domain is somewhere other than DigitalOceanAdd below nameservers:ns1.digitalocean.com
ns2.digitalocean.com
ns3.digitalocean.comNow check if they are propagating by using whatsmydns.net (Enter your IP and change click on A and select NS and click Search)Once they are propagating, add the domain to your DigitalOcean account.Go to your DigitalOcean Dashboard and click on Networking.Add a domain and click Save.Then Edit the domain and add the Droplet to the Domain and save.Now click on the domain name and an A record which points to your droplet.Hope this will resolve your issue. | I created a small hello world node app, then i hosted the app on digital ocean droplet, after that i can access my application onhttp://my_public_ip:3000Felt happy 😍Then i bought a domain name calledhelloworld.tkfree domain from freenom.com

Using the following piece of codeconst DIST_FOLDER = join(process.cwd(), 'dist');

Shall I recreate the Nginx container after each update? if so, how?No, You just need to reload nginx service most of the time.
You can use:docker exec nginxcontainername/id nginx -s reloadordocker kill -s HUP nginxcontainername/idAnother optionwould be using a custom image and check nginx config checksum and reload nginx when ever it changes. Example script:nginx "$@"
oldcksum=`cksum /etc/nginx/conf.d/default.conf`
inotifywait -e modify,move,create,delete -mr --timefmt '%d/%m/%y %H:%M' --format '%T' \

The problem in my case was insufficient disk space mounted on root. I have a huge disk mounted on/home, but only had about 4 GB left on/.

client_body_timeout 300s;
client_body_in_file_only clean;

Your process most likely dies before it manages to finish its work. It's because PHP kills it after the response is returned back to the client and connection is closed.Process::start()is used tostart a process asynchronously. You need to eitherwait()for it to finish or check if it has finished yet withisRunning():$process->start();
$process->wait(function ($type, $buffer) {
// do sth while you wait
});Alternatively, useProcess::run()instead ofProcess:start().Use message queues if you want to process something in background. | In a fresh symfony2-project (installation as describedhere), I would like to start a console-process as part of a request. The app runs on a "standard" ubuntu 14.04 box with nginx + php-fpm.Consider this controller-code:get('kernel')->getRootDir();
$env = $this->get('kernel')->getEnvironment();
$commandline = $rootDir . '/console --env=' . $env . ' acme:hello --who jojo'
$process = new Process($commandline);
$process->start();
return new JsonResponse(array('command' => $commandline));
}
}When I issue a request to /command, I get my expected result and the process starts, e.g. I see it with htop and the like.
When I issue this request again, I get my expected result, but the process to be started does not show up anywhere. No errors, no nothing.Restarting the php5-fpm service enables me to start one process through a request again, so basically I need to restart the whole php-service after each request.

The error was due to a conflict in rules in nginx config file.So, the solution was:location ^~ /protected_files { # ^~ needed according to the [nginx docs][1] to avoid nginx to check more locations

}

}Hope this helps many of you. | I am developing a webapp and X-Accel-Redirect header works fine only in files without extension.

try_files $uri =404;
}For some reason, it seems that nginx tests the existence of the file in the file system first and after that it tries the the "internal/aliased" path.Any ideas about how to let nginx to filter all the "/protected_files" coming from X-Accel-Redirect directly to the "internal" instead of trying to find in other paths first?Thanks in advance. | Nginx: X-Accel-Redirect not working in files with know MIME extension |

You can force HTTP headers to influence the browser caching behavior, however this is probably not a good idea in a production environment where you want caching.So simply use something like:expires -1To forceCache-Control no-cacheheaderCheck here for more information:http://wiki.nginx.org/HttpHeadersModuleThat being said, I have gotten myself in the habit of just changing image and static files names as I revise them.

Rather than doing an HTTP proxy, I would use Nginx'sbuilt-in capacityto communicate with uWSGI. (This will still work if you are using separate Docker containers for Nginx and uWSGI since the communication is done over TCP)A typical configuration (mine) looks like this:location / {

The load balancer is secured with ssl, but the connections to the load balancer are forwarded to the ec2's over standard http on port 80. After hitting an ec2 on port 80 they are forwarded to a docker container on port 8000 (if you are unfamiliar with docker just consider it to be a standard vm). Inside the container nginx listens on port 8000, it handles a redirection for the static files in django and for web requests it forwards the request to django running on 127.0.0.1:8001.

It is possible to run the nginx master process with a different user by just running the init script as non root (i.e./etc/init.d/nginx start).If this is really what you want to do, you will need to ensure the log and pid directories (usually/var/log/nginx&/var/run/nginx.pid) are writable for that user, and all yourlistencalls are for ports greater than 1024 (because binding to ports <=1024 requires root privileges).In most situations however, you run the nginx master process as root and specify theuserdirective so that nginx workers processes run as that user. | A/c tohttp://wiki.nginx.org/CoreModule#usermaster process used to run with root user, is it possible to run nginx mater process with different user? | How to run nginx master process with different user |

If I try to use the domain name xxxxx.com as the name, I am told this message:A client error (NoSuchEntity) occurred when calling the GetServerCertificate operation:
The Server Certificate with name xxxxxxxx.com cannot be found.This happens when I use the identifier and the ARN also.My end goal is to have a signed SSL certificate on NGINX to serve the web content of my EC2 instance.A: Is this the right track? (Are these the right preliminary steps?)B: If so, what do I use to reference the certificate? Or do I use a different API? | How to reference AWS ACM Certificate when using AWS API to get certificate [duplicate] |
This can now be configured within GKE, by using a custom resourceBackendConfig.apiVersion: cloud.google.com/v1beta1
kind: BackendConfig
metadata:
name: my-bconfig
spec:
timeoutSec: 60And then configuring yourServiceto use this configuration with an annotation:apiVersion: v1
kind: Service
metadata:
name: my-service
annotations:
beta.cloud.google.com/backend-config: '{"ports": {"80":"my-bconfig"}}'
spec:
ports:
- port: 80
.... other fieldsSeeConfiguring a backend service through Ingress | I'm running Kubernetes on Google Compute Engine (GCE). I have an Ingress set up. Everything works perfectly except when I upload large files, the L7 HTTPS Load Balancer terminates the connection after 30 seconds. I know that I can bump this up manually in the "Backend Service", but I'm wondering if there is a way to do this from the Ingress spec. I worry that my manual tweak will get changed back to 30s later on.The nginx ingress controller has a number of annotations that can be used to configure nginx. Does the GCE L7 Load Balancer have something similar? | Kubernetes on GCE: Ingress Timeout Configuration |
