Nginx Configuration

  • You need to insert the following code into your nginx config file.
  • The config assumes that ownCloud is installed in /var/www/owncloud and that it is accessed via http(s)://cloud.example.com.
  • Adjust server_name, root, ssl_certificate and ssl_certificate_key to suit your needs.
  • Make sure your SSL certificates are readable by the server (see Nginx HTTP SSL Module documentation).
  • add_header statements are only taken from the current level and are not cascaded from or to a different level. All necessary add_header statements must be defined in each level needed. For better readability it is possible to move common add header statements into a separate file and include that file wherever necessary. However, each add_header statement must be written in a single line to prevent connection problems with sync clients.

Note

The following example assumes that your ownCloud is installed in your webroot. If you’re using a subfolder you need to adjust the configuration accordingly.

upstream php-handler {
  server 127.0.0.1:9000;
  #server unix:/var/run/php5-fpm.sock;
}

server {
  listen 80;
  server_name cloud.example.com;
  # enforce https
  return 301 https://$server_name$request_uri;
}

server {
  listen 443 ssl;
  server_name cloud.example.com;

  ssl_certificate /etc/ssl/nginx/cloud.example.com.crt;
  ssl_certificate_key /etc/ssl/nginx/cloud.example.com.key;

  # Path to the root of your installation
  root /var/www/owncloud/;
  # set max upload size
  client_max_body_size 10G;
  fastcgi_buffers 64 4K;

  # Disable gzip to avoid the removal of the ETag header
  gzip off;

  # Uncomment if your server is build with the ngx_pagespeed module
  # This module is currently not supported.
  #pagespeed off;

}

Note

You can use ownCloud over plain http, but we strongly encourage you to use SSL/TLS to encrypt all of your server traffic, and to protect user’s logins and data in transit.

  • Remove the server block containing the redirect
  • Change listen 443 ssl to listen 80;
  • Remove ssl_certificate and ssl_certificate_key.
  • Remove fastcgi_params HTTPS on;

Note

If you want to effectively increase maximum upload size you will also have to modify your php-fpm configuration (usually at /etc/php5/fpm/php.ini) and increase upload_max_filesize and post_max_size values. You’ll need to restart php5-fpm and nginx services in order these changes to be applied.

Note

ownCloud comes with its own owncloud/.htaccess file. If PHP-FPM is used, it can’t read .htaccess PHP settings unless the htscanner PECL extension is installed. If PHP-FPM is used without this PECL extension installed, settings and permissions must be set in the owncloud/.user.ini file.

Note

If you are using php-fpm please read php-fpm Configuration Notes

Suppressing Log Messages

If you’re seeing meaningless messages in your logfile, for example client denied by server configuration: /var/www/data/htaccesstest.txt, add this section to your Nginx configuration to suppress them:

location = /data/htaccesstest.txt {
  allow all;
  log_not_found off;
  access_log off;
}

JavaScript (.js) or CSS (.css) files not served properly

A common issue with custom nginx configs is that JavaScript (.js) or CSS (.css) files are not served properly leading to a 404 (File not found) error on those files and a broken webinterface.

This could be caused by the:

location ~* \.(?:css|js)$ {

block shown above not located below the:

location ~ \.php(?:$|/) {

block. Other custom configurations like caching JavaScript (.js) or CSS (.css) files via gzip could also cause such issues.
