Nginx is corrupting files on download - php

Question

i'm having a problem with my application made with php and the Laravel Framework.
The issue is with file uploads/downloads.
When i submit files to the server it stores them good, but when i try to download an uploaded file larger than 100KB it just downloads part of it making it corrupt.
Tried a lot of options by adjusting php.ini settings, nginx settings and still can't solve it.
Here is my current configuration for nginx:
nginx.conf
user developer;
worker_processes 4;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}
http {
##
# Basic Settings
##
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
# server_tokens off;
server_names_hash_bucket_size 64;
# server_name_in_redirect off;
include /etc/nginx/mime.types;
default_type application/octet-stream;
##
# SSL Settings
##
ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;
##
# Logging Settings
##
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
##
# Gzip Settings
##
gzip on;
gzip_disable "msie6";
# gzip_vary on;
# gzip_proxied any;
# gzip_comp_level 6;
# gzip_buffers 16 8k;
# gzip_http_version 1.1;
# gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
##
# Virtual Host Configs
##
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}
Now here is my nginx site config:
server {
listen 8002 default_server;
server_name localhost 172.20.74.229 cadeco.dev;
root /var/www/current/cadeco/public;
index index.php index.html index.htm;
access_log /var/log/nginx/cadeco.dev-access.log;
error_log /var/log/nginx/cadeco.dev-error.log error;
charset utf-8;
include h5bp/basic.conf;
location = /favicon.ico { log_not_found off; access_log off; }
location = /robots.txt { log_not_found off; access_log off; }
location ~ /\. {
deny all;
access_log off;
log_not_found off;
}
location / {
try_files $uri $uri/ /index.php$is_args$args;
}
sendfile off;
client_max_body_size 100m;
location ~ ^/index\.php(/|$) {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
}
Then here are the related settings of php.ini from (/etc/php5/fpm/php.ini):
max_execution_time = 30
max_input_time = 60
memory_limit = 512M
upload_max_filesize = 50M
max_file_uploads = 20
And finally here is my php script that does the file download:
public function downloadFile($file)
{
$filePath = storage_path('app/uploads/').$file;
if (Storage::exists($file))
{
return response()->download($filePath);
}
Flash::error('File does not exists!');
return redirect()->back();
}
Thanks for any help in advance! :D

Answer 1

i figured it out!.
I checked the error log for this nginx site and found this error:
*10 open() "/var/lib/nginx/fastcgi/4/00/0000000004" failed (13: Permission denied) while reading upstream, client: 172.20.73.101, server: localhost, request: XXXXX
This error ocurred because some time ago we changed the user to www-data to start services like the php-fpm, but i forgot to change it for nginx.
Changed the user to www-data and now everything works as it should!
Thanks!
