# ownCloud 8.2 Server Administration Manual

# 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 is is possible to move common add header statements into a separate file and include that file wherever necessary.

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;

    }

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 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.
