This is soo odd, I've been receiving:
ActionController::RoutingError (No route matches "/favicon.ico")
but I have the favicon.ico in my public directory... any ideas how to solve this? Nginx doesn't throw an error at all.
Run
rake assets:precompile
then set
config.serve_static_assets = true
in config\environments\production.rb file.
Then restart your server.
But I think rake assets:precompile is not required.
It seems that nginx doesn't handle your static assets (since this request for static file goes to the ActionController). Check public root in nginx config file nginx.conf.
Here is an example with Capistrano deployments:
server {
listen 80;
root /var/www/my_project/current/public;
}
And do you use a favicon_link_tag helper in your head :) ?
If you want to keep config.serve_static_assets = false, which is recommended if you have nginx or apache, you can tell nginx to statically serve the files directly. This is especially important for performance reasons, as you don't want rails serving these assets.
Below is a sample which also correctly has nginx statically serve the assets directory:
server {
listen 80;
root /var/www/my_project/current/public;
location / {
proxy_pass http://mysite;
proxy_redirect off;
proxy_set_header X_FORWARDED_PROTO https;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
}
# static resource routing - both assets folder and favicon.ico
location ~* ^/assets/|favicon.ico {
# Per RFC2616 - 1 year maximum expiry
# http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html
expires 1y;
add_header Cache-Control public;
# Some browsers still send conditional-GET requests if there's a
# Last-Modified header or an ETag header even if they haven't
# reached the expiry date sent in the Expires header.
add_header Last-Modified "";
add_header ETag "";
break;
}
}
Make sure that the favicon.ico file isn't empty (byte size > 0). For some reason I had an empty favicon.ico file which was triggering the same error, even though the file did exist.
delete slash sign before favicon.ico and try to use something like:
<link rel="shortcut icon" type="image/png" href="favicon.ico" />
I was facing the same problem when I first clone code from git repository and run with RAILS_ENV=production. Since there was no assets directory in my git repository, I needed to run rake assets:precompile.
Also I was run with rails s, so config.serve_static_assets = true worked. Thanks #Jiemurat

I have an angularJS web app running in a Nginx server that sends request to a Rails API running in a Puma server. I have integrated Sidekiq 5.2.8 and everything works great but the Sidekiq web interface.
In my Nginx config file, I have a rule to pass request to the API. Please find the whole nginx.conf document:
events {
worker_connections 1024;
}
http {
upstream api.development {
# Path to Puma SOCK file, as defined previously
server unix:/tmp/puma.sock fail_timeout=0;
}
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
# set client body size to 10M #
client_max_body_size 10M;
gzip on;

listen 80 default_server;
listen [::]:80 default_server ipv6only=on;

location ~* \.(?:manifest|appcache|html?|xml|json)$ {
root /Users/Rober/Projects/domain/dev/domain/app;
expires -1;
}
}
include servers/*;
}
In Rails:
routes:
require 'sidekiq/web'
mount Sidekiq::Web => '/sidekiq'
I have included next rule in Nginx config file and now when I request http://localhost/sidekiq I can see the web interface and navigate, but still cannot see the styles.
location /sidekiq {
proxy_pass http://api.development;
}
See screenshot.
The dev tools shows that when I load sideqik is trying to get bootstrap.css and some other css and javascript in http://localhost/sidekiq/stylesheets/bootstrap.css
What am I missing?
UPDATE:
I have found out the root cause of the problem in my nginx.conf. I have next rule that set a cache expiration time for performance purposes. If I comment this code, everything works. But how can I have both things living together?
CSS and Javascript
location ~* \.(?:css|js)$ {
root /Users/Rober/Projects/domain/dev/domain/app;
expires 1w;
add_header Cache-Control "public";
}
UPDATE 2: Just in case the problem comes from another point, I have included my whole nginx conf.
Now, with the provided config, the expiration rules in my web app are still working, but the css in the sidekiq webapp do not.
I have included two headers as debug. One when the server is accessing the location rule and the second when the server is accessing inside the if condition. When I request my home page with localhost and I check the request for my own css, such as app.css, I can see the header X-debug-message: Into the location css if, which is right.
If I request sidekiq with localhost/sidekiq I still get 404 error for css, let´s say http://localhost/sidekiq/stylesheets/bootstrap.css and I can see the header X-debug-message: Into the location css.
Current conclusions:
As soon as I include the location ~* .(?:css|js)$ rule, sidekiq css stops working. Even if the rule is empty, like:
location ~* \.(?:css|js)$ {
}
As soon as I delete or comment the whole rule, the sidekiq css works perfectly, but unfortunately this is not compatible with the expires rules that we need to include for performance purposes.
Try this:
location ~* \.(?:css|js)$ {
if ($uri !~* "^/sidekiq/\w*(.*)+$"){
root /Users/Rober/Projects/domain/dev/yanpy/app;
expires 1w;
add_header Cache-Control "public";
}
}
I wasn't able to find a fix for this, so I hacked it with the following method: I copied sidekiq's assets to the public folder and it started working ( since they're referenced by the UI ).
|- images
|-- favicon.io
|-- logo.png
|-- status.png
|- javascripts
|-- application.js
|-- dashboard.js
|- stylesheets
|-- application.css
|-- application-rtl.css
|-- application-dark.css
|-- application-rtl.min.css
|-- bootstrap.css
Mainly, these files: https://github.com/mperham/sidekiq/tree/master/web/assets
Been having a problem setting up sendfile for nginx+rails lately. We have one kind of file download that's already handled by nginx, and we wanted to add a second rule to deal with another kind of files at another location, but we have no success so far.
Ruby controller :
def download_file
send_file("/srv/www/myapp/shared/tmp/directory/file.zip")
end
Environment configuration file:
Rails.application.configure do
# ..
config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx
# ..
end
Nginx configuration :
upstream myapp {
server 127.0.0.1:9292;
}
server {
listen 80;
server_name myapp.tld;
client_max_body_size 10M;
root /srv/www/myapp/current/public;
# This first block works perfectly
location /__working_file {
internal;
alias /var/lib/myapp;
}
# This second block does not work at all
location /__new_files {
internal;
alias /srv/www/myapp/shared/tmp/directory;
}
location / {
root /srv/www/myapp/current/public;
try_files $uri #app;
}
location #app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $http_host;
proxy_set_header X-Sendfile-Type X-Accel-Redirect;
# This first rule works perfectly
proxy_set_header X-Accel-Mapping /var/lib/myapp/=/__working_file/;
# This second rule doesn't
proxy_set_header X-Accel-Mapping /srv/www/myapp/shared/tmp/directory/=/__new_files/;
proxy_pass_header Server;
proxy_read_timeout 300;
proxy_pass http://myapp;
}
}
Result
When accessing the controller action, the send_file command is triggered, then we get a "File not found" in the browser, nothing gets downloaded, and the rails log shows this:
Sent file /srv/www/myapp/shared/tmp/directory/file.zip (0.4ms)
Completed 200 OK in 169ms (ActiveRecord: 37.5ms)
Started GET "/srv/www/myapp/shared/tmp/directory/file.zip" for 109.190.197.126 at 2018-11-20 11:34:44 +0100
ActionController::RoutingError (No route matches [GET] "/srv/www/myapp/shared/tmp/directory/file.zip"):
The file does exist and is readable but nginx can't seem to access it. Any idea?
The problem comes from the way the two X-Accel-Mapping are set. Rack is indeed able to deal with several mappings since the merge of this PR #1187.
However, as of today, this PR has been merged on master but not released yet (2.0.6 is currently the latest release).
The only thing is, the correct way of setting several mappings is by using one single proxy_set_header rule, and separate each mapping with a comma, like this:
proxy_set_header X-Accel-Mapping, /var/lib/myapp/=/__working_file/,/srv/www/myapp/shared/tmp/directory/=/__new_files/
while routing it is not getting . you have to provide proper route to work.
I have rails application and nginx.
There are parts of the nginx config:
http {
...
proxy_cache_path /var/cache/nginx levels= keys_zone=cache:50m inactive=1d;
...
}
server {
...
location #rails {
proxy_pass http://rails_server;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_read_timeout 300m;
proxy_cache cache;
proxy_cache_valid 1h;
set $proxy_hide_header 'Set-Cookie';
proxy_hide_header $proxy_hide_header;
proxy_ignore_headers "Cache-Control" "Expires";
}
...
}
I have a promblem with caching cross domain requests.
Cache files are created when I open the url my_domain/data.js directly.
Cache files are created when I open the url my_domain/data.js from my_domain/index.html using ajax request.
Cache files are not created when I open the url my_domain/data.js from my_domain2/index.html using ajax request.
Content and http code are ok in all cases.
The problem was in rails (not in nginx).
Rails add "Set-Cookie" header for cross domain requests even if cookie is already set (I don't know why, maybe it's rails bug).
So my solution is:
proxy_ignore_headers "Set-Cookie";
I've a rails app that serves large static files to registered users. I was able to implement it by following the excellent guide here: Protected downloads with nginx, Rails 3.0, and #send_file. The downloads and everything else is working great, but there is just this problem - The Content-Length header isn't being sent.
It's okay for small files, but it gets really frustrating when large files are downloaded, since download managers and browsers don't show any progress. How can I fix this? Do I have to add something to my nginx configuration or do I have to pass along some other option to the send_file method in my rails controller? I have been searching online for quite some time but have been unsuccessful. Please Help! Thanks!
Here's my nginx.conf:
upstream unicorn {
server unix:/tmp/unicorn.awesomeapp.sock fail_timeout=0;
}
server {
listen 80 default_server deferred;
# server_name example.com;
root /home/deploy/apps/awesomeapp/current/public;
location ~ /downloads/(.*) {
internal;
alias /home/deploy/uploads/$1;
}
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #unicorn;
location #unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_set_header X-Sendfile-Type X-Accel-Redirect;
proxy_set_header X-Accel-Mapping /downloads/=/home/deploy/uploads/;
proxy_pass http://unicorn;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 20M;
keepalive_timeout 10;
}
Okay, here's something. I don't know if it's the right way or not but I was able to fix the issue by manually sending the Content-Length Header from my Rails Controller. Here's what I'm doing:
def download
#file = Attachment.find(params[:id])
response.headers['Content-Length'] = #file.size.to_s
send_file(#file.path, x_sendfile: true)
end
nginx should be automatically able to set the header. There must be something that I'm missing; but until I find a 'proper' solution, I guess this will have to do.
P.S: The Header needs to be a string to work properly with some webservers, hence the .to_s
I am trying to use the HTTP_IF_MODIFIED_SINCE header in my app to determine if resources are stale/fresh and render 200/304 in those cases.
In my dev environment everything works fine but I can't for the life of me get it to work in production.
I am using Passenger 3.0.11 and Nginx 1.0.13.
As you see below, I tried proxy_pass_header, proxy_set_header, passenger_pass_header and passenger_set_cgi_param. The last one actually sets a HTTP_IF_MODIFIED_SINCE header but it is empty...
Any help/ideas would be greatly appreciated!
My config:
server {
listen 80 default_server;
root /home/rails/myapp/current/public;
passenger_enabled on;
charset utf-8;
proxy_pass_header If-Modified-Since;
proxy_set_header If-Modified-Since $http_if_modified_since;
passenger_pass_header If-Modified-Since;
passenger_set_cgi_param HTTP_IF_MODIFIED_SINCE $http_if_modified_since;
if (-f $document_root/system/maintenance.html) {
rewrite ^(.*)$ /system/maintenance.html break;
}
location ~ \.(aspx|jsp|cgi)$ {
return 410;
}
location ~ ^/(assets)/ {
# http://guides.rubyonrails.org/asset_pipeline.html#server-configuration
# gzip_static on;
expires 1y;
add_header Cache-Control public;
add_header Last-Modified "";
add_header ETag "";
break;
}
}
to get it working with non-standard headers, containing underscores, do this inside your http or server block in the nginx.conf file:
underscores_in_headers on;
ignore_invalid_headers off;
and in the server block:
proxy_pass_header HTTP_IF_MODIFIED_SINCE
This can be useful if you have legacy HTTP headers which you need to deal with, and which contain underscores.
This was a user error after all. I sent the header to the app in the wrong format (IF_MODIFIED_SINCE instead of If-Modified-Since). After fixing that, it worked without any of the extra directives.
