===================
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 <http://wiki.nginx.org/HttpSslModule>`_).

.. 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.

.. 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 are using php-fpm please read :ref:`using_php-fpm`

Suppressing Log Messages
------------------------

If you're seeing meaningless messages in your logfile, for example `client 
denied by server configuration: /var/www/data/htaccesstest.txt 
<https://forum.owncloud.org/viewtopic.php?f=17&t=20217>`_, 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.
