Actually I think it is much easier to change the nginx re-write rules than to write middleware for django to do this. After reading up on how nginx processes it's location matching (most exact -> least exact) I created locations for /media and /download as well as a catch all location for / I then moved the rewrite rule to under the / location and simplified it - as I'm no longer worried about checking for files because this entire location is passed to django - the rule becomes :set $subdomain "";
set $subdomain_root "";
if ($host ~* "^(.+)\.domain\.com$") {
set $subdomain $1;
set $subdomain_root "/profile/$subdomain";
rewrite ^(.*)$ $subdomain_root$1;
break;
}and would probably be even simpler if my nginx\regex scripting was better :) | I currently have the following (hacky) re-write rule in my nginx.conf to allow dynamic sub-domains to be re-directed to one Django instance.set $subdomain "";

TLDR: This scary error message proves the conversion/s are actually being received by Twitter, so thankfully there's not much to worry about.I'm getting the same console error when implemented as perTwitter's Google Tag Manager instructions.

Twitter's servers however providecontent-type:text/html;charset=utf-8as a response header.The latest version of Chrome obviously doesn't like loadingtext/htmlinto instances ofImage, but could probably be logging a nicer error message, especially since the response also includes aContent-Length: 0header indicating there's nothing to see. | I'm trying to loadTwitter's tracking pixelon my Meteor/NodeJS website.The code they provide is:!(function(e, t, n, s, u, a) {

I've deployed a couple of simple applications on Linode and found their documentation to be excellent. In particular they have step-by-step tutorials tailored to specific environments. For example, in my case (like you) I wanted to use nginx, and I was using Ubuntu 10.04, so I followed this guide:http://library.linode.com/frameworks/ruby-on-rails-nginx/ubuntu-10.04-lucidIf it's your first time setting up on a VPS there will be some hurdles certainly, but I found the experience to be very rewarding.Regarding hosting your code, you have a number of options, but keep in mind that this is really a separate issue from deploying your app. You deploy your app on linode, but you don't have to host your code there, although you certainly can.In general terms, if you're okay with making your code open, then certainly github is a good choice. If you want to keep the code private but still have access online (rather than just on one computer), you can take advantage of your linode machine and host your code there.If you will have a number of other people contributing to the codebase, you might consider setting upgitosisorgitolite, which make it easy to do this. Alternatively if you will be the main user contributing to the codebase, you can setup a simpler configuration through HTTP, explained here:http://dev.bazingaweb.fr/2011/02/23/how-to-set-up-git-over-http.htmlLinode also has documentation on setting up a remote git repository:https://library.linode.com/linux-tools/version-control/gitIf you're choosing between gitosis and gitolite, I'd go with gitolite since gitosis appears to have been abandoned and is no longer being actively maintained.Other references on deploying on linode:http://infinite-sushi.com/2011/01/deploying-a-rails-app-to-a-linode-box/http://blog.chris-spencer.co.uk/from-zero-to-git-deployment-on-linode | I'm planning to host a Rails application on Linode, but I'm still unsure about the requirements and process of deploying.

If you don't know why you need Nginx or Apache on top of Node.js, then you don't need it.Nginx does a few things faster (and in some cases easier to configure) than Node.js: proxying, url rewriting, http caching, redirection, static file serving, and load balancing.If you experience that your Node.js code for any of these roles are growing complex, or turn out to be performance bottlenecks, it's worth investigating.

I think it is not possible to use a symlinked public directory. The only workaround I can imagine is to symlink any file and directory inside of the public dir.# public folder: /data/public
# app folder: /webapp/
mkdir -p /webapp/public && ln -sf /data/public/* /webapp/public/For every new file or directory in /data/public you have to run this command again. | I'm putting together a rails deployment where the public directory is a
symlink to another directory on the system. This is with passenger 3 on
nginx .8. It does't seem to like that setup. Nginx always follows symlinks by default, so AFAIK it's not a matter of doing the equivalent of Apache's +FollowSymLinks.updateLooks like this is covered here:http://www.modrails.com/documentation/Users%20guide%20Nginx.html#application_detectionNote that Phusion Passenger for Nginx
does not resolve any symlinks in the
root path. So for example, suppose
that your root points to
/home/www/example.com, which in turn
is a symlink to
/webapps/example.com/public. Phusion
Passenger for Nginx will check for
/home/www/config/environment.rb, not
/webapps/example.com/config/environment.rb.
This file of course doesn’t exist, and
as a result Phusion Passenger will not
activate itself for this virtual host,
and you’ll most likely see some output
generated by the Nginx default
directory handler such as a Forbidden
error message.Detection of Rack applications happens
through the same mechanism, exception
that Phusion Passenger will look for
config.ru instead of
config/environment.rb.So I wonder if some proper symlinking of config.ru might do the trick. | Can my /public directory be a symlink with rails 3 + passenger 3 + nginx 0.8? |

The instructions you are referring to are for compiled installation.Assuming you want to add the moduleto your existingNGINX install, below are the generic steps that will get things running.Fetch exactly matching version of NGINX as the one you have installed, from nginx.org onto your system and extract it to, say,/usr/local/src/nginxgit cloneNGINX module's source code onto your system, to e.g./usr/local/src/nginx-module-foocd /usr/local/src/nginx. This is where you will find theconfigurescript. You will basically configure NGINX with the location of theconfigof specific module in question, thus next step:./configure --add-dynamic-module=../nginx-module-foo --with-compatmakeAs a resulf of the compilation you will have module's.sofile somewhere inobjsdirectory of your NGINX sources. You will then copy it over to e.g./usr/lib64/nginx/modules/directory.To make your existing NGINX load the module, addload_module modules/foo.so;at the very top of/etc/nginx/nginx.conf.You can decipher the many downsides to the whole compiled approach: one is having compilation software (gcc) on a production system, other is having to re-do all those steps any time you upgrade NGINX or the module.For the reasons mentioned, you might want to search for a packaged install of third-party modules.For CentOS/RHEL systems, you might want to look at GetPageSpeed repos (subscription-ware, and I'm biased to mention it, because I'm the maintainer. But this is free for CentOS/RHEL 8 at the time of this writing. Installing the module you want,goes downto a couple of commands:yum -y install https://extras.getpagespeed.com/release-latest.rpm

Can Lambda do it? Yes. Should Lambda do it? No.Why? Cost.First, let's say you do handle20k Requests / Second, every second for an entire day. That will then equate to1.728 Billionrequests in that day. In the free tier, you do get 1 Million requests free, so that drops the billable requests down to 1.727 Billion. Lambda charges$0.20 / Million Requests, so:1.728 Billion requests * $0.20 / Million requests = $345.40I'm pretty sure your cost for EC2 is lower than thatper day. Taking them4.16xlargeinstance, withon-demandpricing, we get:$3.20 / Hour * 24 Hours = $76.80See the difference? But, Lambda also charges for compute time!Let's say you include thec++executable in your Lambda function (called fromPythonorNode, so we won't take into account the performance hit going fromc++to an interpreted language. Since Lambda charges in100 Millisecondblocks, rounded up, for this estimate we will assume that all the requests finish within100 Milliseconds.Say you use the smallest memory size,128 MB. That will give you3.2 Million Secondswithin the free tier, or32 Million Requestsgiven that they are all under100 Milliseconds, free. But that still leaves you with1.696 Billion Requestsbillable. The cost for the128 MBsize is$0.000000208 / 100 Milliseconds. Given that each request finishes under100 Milliseconds, the cost for the execution time will be:$0.000000208 / 100 Milliseconds * 1.696 Billion 100 Millisecond Units = $352.77Adding that cost to the cost of the requests, you get:$345.40 + $352.77 = $707.17EC2:$76.80Lambda:$707.17Note, this is just using the 20k Requests / Second number that you gave and is for asingle day. If the actual number of requests differs, the requests take longer than 100 Milliseconds, or you need more memory than 128 MB, the cost estimate will go up or down accordingly.Lambda has its place, but EC2 does also. Just because you can put it on Lambda doesn't mean you should. | On a project I’m working on, there are a number of web services implemented on AWS. The services that are relatively simple (DynamoDB insert or lookup) and will be used relatively infrequently have been implemented as Lambdas, which were perfect for the task. There is also a more complex web service which does a lot of string processing and regex matching which needs to be highly performant, that has been implemented in C++ (roughly 5K LOC) as a Nginx module and can handle in the region of 20K requests/s running on an EC2 instance (the service just takes in a small JSON payload, does a lot of string processing and regex matching against some reference data that sits in static data files on S3, and returns a JSON response under 1KB in size)There is a push from management to unify our use of AWS services and have all the web services implemented as Lambdas.My question is: can a high performance web service such as the C/C++ nginx compiled module running on EC2 that’s expected to run continuously and handle 20K to 100K req/s actually be converted to AWS Lambda (in Python) and expected to have the same performance or is this better left as is on EC2?

Yes, it's buffering issue. If you are using few workers - each worker has own buffer.Ways to improve:disable bufferingdecrease buffer size (1)addflushoptions, if
flush to disk still rarecreate own log collector with sorting
(nginx can syslog protocol, for example)But usually you don't need to care about order of log records. Log analytic systems will sort it by self.(1) For linux systems buffer size must not exceed the size of an atomic write to a disk file. In modern linux - it's 64k. Well, I'm not 100% sure about this size because information very discrepant. But if you will find broke lines in log - decrease this size. | Records in my nginx log file are out of order. (Edit: by "out of order" I mean chronologically. e.g. Log lines for 2017-02-21 09:13:26 will often bebeforelines for 2017-02-21 09:13:45) Perhaps a certain amount of out of order records are to be expected because they are logged after a request is completed, not when received. But this is a way higher number of requests that are being logged out of order, including known short (fast) requests for small static files.Is this a known side effect of using buffered logging or can this be improved?For getting a more complete picture, here are some other config params:Innginx.conf:log_format main '$remote_addr - $remote_user [$time_local] "$request" 'In the config file for the virtual host:server {

Did you take a look atServer Sent Eventsas you are initiating your request via ajax so you aren't performing bidirectional communication; you only want server to push you updates when it has ones | Closed. This question isopinion-based. It is not currently accepting answers.Want to improve this question?Update the question so it can be answered with facts and citations byediting this post.Closed9 years ago.Improve this questionScenarioI am developing some sort of web based cloud storage service.One feature is that the user can initiate transcoding of video files (so that they can be streamed on different devices).This takes some time and I want to display a progress bar to the user.My plan is to submit the job using ajax where it is written into a database. The ajax call returns the ID of the job in the database, and this id will be used as the channel for notifications.So when the job has been submitted, the client subscribes to the channel "job-databaseID" on some self hosted websocket server.Transcoding workers then periodically select pending jobs from the database table and process them. While processing they push their progress to the websocket server to the same channel where the client is listening.The front-end application should be a website with javascript and jquery.
The back end should be programmed in PHP and MySQL and an apache or nginx webserver.QuestionIs this a proper way of using websockets?
Usually I see websockets employed in aon-to-manynotification scenario. Here it is aone-to-onenotification scenario.
Are there maby better alterantives for this kind one way information flow?Also I often see channels for Websocket scenarios to be more or lesslong-lived. Here it is veryshort-lived. Would it maby make more sense to make one channel per user?What would be a good websocket server for that kind of use? Ideally the channels would be auto-removed once no client is connected to it any more and auto-created the same way, so I don't need to take care of that. | Are websockets the right technology to be used to update progress bars for the client and how to implement it?

No, error log writes aren't buffered. | We're looking to watch nginx error logs for modifications but having some difficultly accounting for edge cases such as file truncations, etc.It would be helpful to know if nginx writes its error log files on the fly or if it buffers writes to error logs.

Pipelines are quite different in logstash and fluentd.

format /^(?[^ ]*) (?[^ ]*) \[(?[^\]]*)\] (?[^ ]*) (?[^ ]*) \[(?[^\]]*)\] "(?\S+[^\"])(?: +(?[^\"]*?)(?: +\S*)?)?" (?[^ ]*) (?[^ ]*)(?: "(?[^\"]*)" "(?[^\"]*)")? (?[^ ]*) (?[^ ]*) (?:\[(?[^\]]*)\] )?(?[^ ]*) (?[^ ]*) (?[^ ]*) (?[^ ]*)$/

key_name log
types server_port:integer,code:integer,size:integer,request_length:integer,request_time:float,upstream_response_length:integer,upstream_response_time:float,upstream_status:integer
reserve_data yes
Long answer with lots of examples is here:https://github.com/kayrus/elk-kubernetes/ | I'd like to parse ingress nginx logs using fluentd in Kubernetes. That was quite easy in Logstash, but I'm confused regarding fluentd syntax.Right now I have the following rules:

I get the same file when I CURL localhost while ssh'd into the vm.EDITIt actually does the same thing when I edit the file via SSHI can reload the vm via vagrant (which re-syncs the folders) and it works fine until the next remote change.Restarting nginx and gunicorn doesn't help.Does vagrant lock the files so that nginx has to rely on a cache? What might be going on here?Thanks! | NGINX not picking up changes in Vagrant Synced folder |
Gotya! Chef 11 feature. Issue with it exist in chef-solo solely :)To make a quick resume, difference is:chef.add_recipe() - loads entire cookbook context (all the files, e.g. recipes, definitions, attributes...)include_recipe "" - files(attributes, definitions etc.) that are not in the expended run list are not loaded.There are at least 4 ways to solve the issue(put files in the run list):include_attribute - include desired attribute file explicitly.metadata.rb->dependency - if your cookbook is using recipe from another cookbook, put that cookbook in metadata.rb's dependency section, and all it's files will be loaded.chef.add_recipe() - Load recipe via Vagrantfile. (Mentioned here just for reference)Berkshelf - you may use this cookbook manager to solve the issue as well. Here's theStackoverflow thread about this exact problemandsome DocsFor those who are interested in further reading, Chef 11 introduced dependency-based cookbook loading for non-recipe files. The new loading logic means that files belonging to cookbooks which exist in the cookbook_path but are not in the expanded run_list or dependencies of the cookbooks in the expanded run_list will no longer be loaded.

If you don't need HTTP access to your subversion repository, all you need to do is just install subversion and create a repository like this:svnadmin create /path/to/repositoryThen you can check out local copies directly:svn co /path/to/repository /path/to/my/checkoutOr over ssh:svn co svn+ssh://server/path/to/repositoryIf your packaging system is trying to install Apache with subversion, that is a packaging issue.

I was asking the same question myself so I did some digging around and here is what I found out:Certbot mainly uses 80 or 443 ports for challenges (http-01andtls-sni-01) to verify domain ownership as it is described incertbot docs:Under the hood, plugins use one of several ACME protocol challenges to
prove you control a domain. The options are http-01 (which uses port
80), tls-sni-01 (port 443) and dns-01 (requiring configuration of a
DNS server on port 53, though that’s often not the same machine as
your webserver). A few plugins support more than one challenge type,
in which case you can choose one with --preferred-challenges.Looking atcertbot_nginxplugin implementationofhttp-01challenge we can see that plugin edits nginx configuration to include additional server block that is used to perform the challenge:def _make_server_block(self, achall):

}Basically, I would like Nginx to try upstream A, and if A returns a 404, then try upstream B instead, and failing that, return a 404 to the client.try_filesdoes this for filesystem locations, then can fall back to a named location, but it doesn't work for multiple named locations. Is there something thatwillwork?Background:I have a Django web application (upstream A) and an Apache/Wordpress instance (upstream B) that I would like to coexist in the same URL namespace for simpler Wordpress URLs:mysite.com/hello-world/instead ofmysite.com/blog/hello-world/.Icouldduplicate my Django URLs in the Nginx locations and use wordpress as a catch-all:location /something-django-handles/ {
proxy_pass http://A/;
}
location /something-else-django-handles/ {
proxy_pass http://A/;
}
location / {
proxy_pass http://B/;
}But this violates the DRY principle, so I'd like to avoid it if possible. :) Is there a solution? | How to configure Nginx to try two upstreams before 404ing? |
...BYTES_TO_CIPHER_LIST:inappropriate fallback) while SSL handshaking, client: 10.0.2.2, server: 0.0.0.0:443This looks like someone checking if the server supports TLS_FALLBACK_SCSV, which it does in your case. Nothing to worry about. On the contrary this means that your server supports a useful security feature. For more information about TLS_FALLBACK_SCSV and how one can detect SSL downgrade attacks likePOODLEthis way you might have a look athttp://www.exploresecurity.com/poodle-and-the-tls_fallback_scsv-remedy/.TLS_FALLBACK_SCSV is a fairly new option intended to detect SSL downgrade attacks. It needs support on client and server. Older nginx/OpenSSL and older browsers simply did not have this option so this problem could not have been detected and thus not logged in earlier versions. This message is critical because it could indicate an actual SSL downgrade attack attempt against the client which was defeated by this option. In practice it is probably some tool probing for support of the option, likeSSLLabs.For reference the relevant code from ssl/ssl_lib.c function ssl_bytes_to_cipher_list:/* Check for TLS_FALLBACK_SCSV */

It should be checked, but as I understood lifetime of the zone items relates to the active connections.Sozone=one:1mcan hold up to16 K unique IPsamong currently (simultaneously)active connections(total number of the active connections at the moment can exceed 16 K, because a few connections can be opened from the same IP).So zone size in mb should be >= number of simultaneous connections from the unique IPs / 16K.Notethat if users share single IP over the NAT that is rather often for USSR providers then you willlimit request frequency for the bunch of usersthat can be very inconvenient for them, so to handle this case you should setrate = simult_users_with_same_ipr/s | According to nginx documentation onlimit_req_zoneOne megabyte zone can keep about 16 thousand 64-byte states. If the zone storage is exhausted, the server will return the 503 (Service Temporarily Unavailable) error to all further requests.I wonder in what way these zones get cleared? For example if we have smth likelimit_req_zone $binary_remote_addr zone=one:1m rate=1r/s;and the number of unique users per a day exceeds 16000 - does it mean that the zone will get overflown and other users will start getting 503 error for the set up location? Or is there a time frame of user's inactivity after which the-user-related-zone-memory will be cleaned?My main concern here is to set an optimal zone size without a risk of getting it exhausted

I eventually went back to the first approach, because it's not convenient to add a query parameter to a url for this. It makes the client logic unnecessary complex.I found the solution to my first approach. The regex in the location statement was wrong. You need to capture the regex in variable names by using ? like this:location ~ ^/fwd/(?\w+)/(?.*)$Then $fwd_alias will contain the alias like foo or bar. $fwd_path with contain the whole path after that.To pass on the full path including optional query parameters you specify the proxy_pass as:proxy_pass http://$repo_url$fwd_path$is_args$args;That's it!So now, including the mapping in the first example, and adding the resolver, it comes down to:location ~ ^/fwd/(?\w+)/(?.*)$ {
resolver 8.8.8.8;
add_header Access-Control-Allow-Origin "*";
proxy_pass http://$repo_url$fwd_path$is_args$args;
proxy_redirect off;
access_log on;
}And a request with the following path:http://localhost:8080/fwd/foo/something/else?with=querymaps to:http://foo.domain.nl/something/else?with=query | I'm trying to get the following pattern to work. I need to specify a dynamic path in my client side code to be able to switch to a few predefined hosts. I map these hosts by appending their alias to a /fwd/ url. The alias is mapped to the real server in nginx like this:map $uri $repoUrl {
default invalid;
~^/fwd/foo/.* http://foo.domain.nl/;
~^/fwd/bar/.* http://bar.domain.nl/;
}Then in the server config part I catch any url starting with fwd and apply the mapped alias value. The remaining part of the url, after the alias should be appended to the url as well.location /fwd/(\w+)/(.*)$ {
add_header X-FwdHost "$repoUrl$2";
add_header Access-Control-Allow-Origin "*";
proxy_pass "$repoUrl$2";
proxy_redirect off;
access_log on;
}If I test this with:curl -i http://localhost:8080/fwd/foo/something/elseI get:X-FwdHost: http://foo.domain.nl/But when test the results from the regexp I get:$1: foo
$2: something/elseSo overall it seems to be working. The regex appears to be ok, but I can't get it to concatenate into one string? Any ideas or is there an easier/better way to accomplish the same?[EDIT]I found a possibly much easier way to do this, by using a query parameter named forward. First map the query parameter to a the right host:map $arg_forward $repo_forward {
default http://invalid_repo_forward/;
foo http://foo.domain.nl/;
bar http://bar.domain.nl/;}Then use the parameter in the path to be forwarded:location /fwd/ {
add_header X-FwdHost $repo_forward;
add_header Access-Control-Allow-Origin "*";
proxy_pass $repo_forward;
proxy_redirect off;
access_log on;
}I would expect and url like:http://localhost:8080/fwd/?forward=fooTo result in:http://foo.domain.nl/...but still this doesn't work. I get a 404 returned. What am I missing? | Dynamic proxy_pass with map and regexp |
In general, I don't believe this is possible. But, you might be able to hack something together based onthis article.Quoting relevant parts:2ed version is here:How to reference OS Environment Variables in nginx.confPosted at Nginx Forum:http://forum.nginx.org/read.php?2,215269,215278#msg-215278and furtherYou can read system environment variables with ngx_lua enabled in your
