===================
Nginx configuration
===================

This page covers example Nginx configurations to use with running an Nextcloud
server. This page is community-maintained. (Thank you, contributors!)

-  You need to insert the following code into **your Nginx configuration file.**
-  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>`_).
-  ``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.
-  Be careful about line breaks if you copy the examples, as long lines may be
   broken for page formatting.
-  Some environments might need a ``cgi.fix_pathinfo`` set to ``1`` in their
   ``php.ini``.

Nextcloud in the webroot of nginx
---------------------------------

The following configuration should be used when Nextcloud is placed in the
webroot of your nginx installation. In this example it is
``/var/www/nextcloud`` and it is accessed via ``http(s)://cloud.example.com``

.. code-block:: nginx

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

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

  server {
      listen 443 ssl http2;
      listen [::]:443 ssl http2;

Tips and tricks
---------------

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:

.. code-block:: nginx

        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:

.. code-block:: nginx

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

block shown above not located **below** the:

.. code-block:: nginx

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

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