I am working on a Ruby on Rails project on an Ubuntu server. Whenever I try and access the app, I am always greeted with:
Welcome to nginx!
If you see this page, the nginx web server is successfully installed and working. Further configuration is required.
Here is my code from the "sites_enabled" directory:
pstream unicorn_site {
server unix:/tmp/unicorn.site.sock fail_timeout=0;
}
server {
listen 80;
client_max_body_size 4G;
keepalive_timeout 10;
error_page 500 502 504 /500.html;
error_page 503 #503;
server_name http://[ip_address];
root /data/site/current/public;
try_files $uri/index.html $uri #unicorn_site;
location #unicorn_site {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn_site;
# limit_req zone=one;
access_log /var/log/nginx/site.access.log;
error_log /var/log/nginx/site.error.log;
}
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
location = /50x.html {
root html;
}
location = /404.html {
root html;
}
location #503 {
error_page 405 = /system/maintenance.html;
if (-f $document_root/system/maintenance.html) {
rewrite ^(.*)$ /system/maintenance.html break;
}
rewrite ^(.*)$ /503.html break;
}
if ($request_method !~ ^(GET|HEAD|PUT|PATCH|POST|DELETE|OPTIONS)){
return 405;
}
if (-f $document_root/system/maintenance.html) {
return 503;
}
}
I am not sure what the problem is as the app seems to have everything it need to be working correctly. I can provide any part of the code anyone needs. Help is much appreciated.
EDIT: I am also always getting this error when I attempt to load the page:
2018/06/15 15:39:10 [warn] 15280#0: server name "http://[ip_address]" has suspicious symbols in /etc/nginx/sites-enabled/site:14

I have configured Nginx with client_max_body_size 100M;
Although still, I am facing an error while uploading a file of 25 MB
The nginx.conf is as follows:
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
The ngnix.conf has an included conf file which is as follows:
client_max_body_size 100M;
upstream third-party{
server cognitiveview-thirdparty;
}
server {
listen 443 ssl;
ssl_certificate <key1>;
ssl_certificate_key <key2>;
server_name <>;

location / {

send_timeout 1500s;
proxy_ssl_server_name on;
client_max_body_size 100M;
}
}
server {
listen 80;
server_name <>;
return 301 https://$host$request_uri;
client_max_body_size 100M;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
client_max_body_size 100M;
}
location /uploads {
client_max_body_size 100M;
}
}
I tried multiple which suggests setting the client_max_body_size in server, location, and HTTP. As per my understanding, I have updated the values, although still I am not successful in uploading the file for a larger size.
The file is being uploaded through a react application which is going to nginx to a backemd
Below is my AWS NGINX config file. I am using rich text with active storage in my new rails app after upload when i am trying to open a file it gives me 404 error in production where in development it works really fine.

Whenever i open Link with file extension it shows me 404 error but if i open the same link without file extension it works Link without file extension. Not sure what i am doing wrong please help
Try disabling the below blocks in your Nginx, this might fix it
location ~ \.(png|jpg|jpeg|gif|ico|html|woff|woff2|ttf|svg|eot|otf|pdf)$ {
gzip_static on;
gzip on;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_vary on;
gzip_proxied any;
expires max;
access_log off;
add_header Cache-Control public;
add_header Access-Control-Allow-Origin *;
}
location ~* \.(?:jpg|jpeg|gif|png|ico|cur|gz|svg|mp4|ogg|ogv|webm|htc|pdf)$ {
access_log off;
add_header Cache-Control "max-age=2592000";
}
I've got a problem with proxying of subdomain's name from nginx to rails server. In my rails app I have links like tenant1.localhost:3000, tenant2.localhost:3000, etc. and it works fine. On production I use Nginx + Puma and nginx doesn't proxy to puma any request if I open link with subdomain.
nginx.conf
upstream puma_muninn {
server app:3000;
}
server {
listen 80;
client_max_body_size 4G;
keepalive_timeout 10;

production.rb
config.action_dispatch.tld_length = 2
But as I said puma doesn't even get requests from nginx.
Any ideas?
A domain in nginx.conf has to be specific instead of localhost.
Using Rails 4.3. I have the following line in production.rb:
# Enable serving of images, stylesheets, and JavaScripts from an asset server.
config.action_controller.asset_host = "https://assets.example.com"
And the following in example.conf nginx:
upstream example {
server unix:/home/deployer/example/shared/tmp/sockets/puma.sock fail_timeout=0;
}
server {
listen 80;
server_name example.com;
client_max_body_size 4G;
keepalive_timeout 10;
error_page 500 502 503 504 /500;
root /home/deployer/example/current/public;
try_files $uri/index.html $uri.html $uri #example;
location #example {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://example;
}
location = /50x.html {
root html;
}
location = /404.html {
root html;
}
location #503 {
error_page 405 = /system/maintenance.html;
if (-f $document_root/system/maintenance.html) {
rewrite ^(.*)$ /system/maintenance.html break;
}
rewrite ^(.*)$ /503.html break;
}
if ($request_method !~ ^(GET|HEAD|PUT|PATCH|POST|DELETE|OPTIONS)$ ){
return 405;
}
if (-f $document_root/system/maintenance.html) {
return 503;
}
}
I notice that my subdomain http://assets.example.com is the mirror of my main domain https://example.com, instead of just serving the assets. For example, https://assets.example.com/blog/1 is the same for https://www.example.com/blog/1.
How do I prevent that? I just want https://assets.example.com to serve static assets.
I think that you should split your nginx server section into two sections, one for the web, the other one for the static assets site.
The server section for the web should remain essentially the same as in your original post, it should perhaps just react on the full hostname:
server_name www.example.com;
The static site server section should be an amended copy of the main site section, with the following principal differences:
the server_name should contain assets.example.com
the section should contain NO proxy_pass directive, static assets are meant to be served statically, i.e. directly by nginx, without having to go through Rails
the root will be the same as in the main site
the asset files will be served directly from the root, relatively, so if there is /assets/ in your URLs (which there probably is), then the assets should be found and served directly from your public/assets physical directory.
Update: sample nginx configuration:
upstream example {
server unix:/home/deployer/example/shared/tmp/sockets/puma.sock fail_timeout=0;
}
# main site config
server {
listen 80;
server_name www.example.com;
client_max_body_size 4G;
keepalive_timeout 10;
error_page 500 502 503 504 /500;
root /home/deployer/example/current/public;
try_files $uri/index.html $uri.html $uri #example;
location #example {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://example;
}
location = /50x.html {
root html;
}
location = /404.html {
root html;
}
location #503 {
error_page 405 = /system/maintenance.html;
if (-f $document_root/system/maintenance.html) {
rewrite ^(.*)$ /system/maintenance.html break;
}
rewrite ^(.*)$ /503.html break;
}
if ($request_method !~ ^(GET|HEAD|PUT|PATCH|POST|DELETE|OPTIONS)$ ){
return 405;
}
if (-f $document_root/system/maintenance.html) {
return 503;
}
}
server {
listen 80;
server_name assets.example.com;
client_max_body_size 4G;
keepalive_timeout 10;
root /home/deployer/example/current/public;
location = /404.html {
root html;
}
if ($request_method !~ ^(GET|HEAD|PUT|PATCH|POST|DELETE|OPTIONS)$ ){
return 405;
}
if (-f $document_root/system/maintenance.html) {
return 503;
}
}
I have a rails app in production on a server using nginx and unicorn to serve files for an iOS app, i need an authentication process in order to send the files to a client, the code i use to do it is:
def download_pdf
if can_purchase
route = #asset_file.asset_zip.url
send_file route, :type=>"application/zip", :x_sendfile=>true
else
render :status=>400, :json=>{:message=>"The user cannot download this issue."}
end
end
The url of the asset file is a location inside the Rails app directory on /downloads/zip/filename.zip.
On the iOS app i have a delegate to listen for the event dispatched when a chunk of downloaded data is written so i can update a progress view. The code is very simple and it goes like this:
- (void)URLSession:(NSURLSession *)session downloadTask:(NSURLSessionDownloadTask *)downloadTask
didWriteData:(int64_t)bytesWritten
totalBytesWritten:(int64_t)totalBytesWritten
totalBytesExpectedToWrite:(int64_t)totalBytesExpectedToWrite {
if (totalBytesExpectedToWrite == NSURLSessionTransferSizeUnknown) {
NSLog(#"Unknown transfer size");
}
else{
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
self.zipDownloadInfo.downloadProgress =
(double)totalBytesWritten / (double)totalBytesExpectedToWrite;
self.progressBarZip.progress = self.zipDownloadInfo.downloadProgress;
}];
}
}
When i was on development stage this worked like a charm, but when i uploaded to my server the download process does not displays the size of the download, but it does downloads the file correctly anyway. Now i am using the X-Accel-Redirect header directive for nginx. My unicorn.conf file is pretty standard and my nginx.conf configuration files is:
user www-data;
worker_processes 4;
pid /var/run/nginx.pid;
events { worker_connections 1024; }
http {
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
server_tokens off;
include /etc/nginx/mime.types;
default_type application/octet-stream;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
gzip on;
gzip_disable "msie6";
gzip_types text/plain text/xml text/css text/comma-separated-values;
upstream app_server { server 127.0.0.1:8080 fail_timeout=0; }
include /etc/nginx/conf.d/*.conf;
server {
listen 80;
root /home/rails/public;
server_name _;
index index.htm index.html;
location / {
try_files $uri/index.html $uri.html $uri #app;
}
location ~* ^.+\.(jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|mp3|flv|mpeg|avi)$ {
try_files $uri #app;
}
location #app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
}
}
}
UPDATE
I found a blog post that points out that i need to set the X-Accel_Mapping header, now i have done it but i get a not found route error, this are the lines i added to nginx.conf
location /downloads/zip/ {
internal;
root /home/rails/;
}
location #app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
proxy_set_header X-Sendfile-Type X-Accel-Redirect;
proxy_set_header X-Accel-Mapping /downloads/zip/=/downloads/zip/;
}
