# 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).
- `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`.

Thanks to @josh4trunks for providing / creating these configuration examples.

## 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`

    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;
        server_name cloud.example.com;

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

## 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:

    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.
