# Nginx configuration

This page covers example Nginx configurations to use with running a Nextcloud server. These configurations examples were originally provided by @josh4trunks and are 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`.

## 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/php/php7.2-fpm.sock;
    }

    server {
        listen 80;
        listen [::]:80;
        server_name cloud.example.com;
        # enforce https
        return 301 https://$server_name:443$request_uri;
    }

    server {
        listen 443 ssl http2;
        listen [::]:443 ssl http2;
        server_name cloud.example.com;

        # Use Mozilla's guidelines for SSL/TLS settings
        # https://mozilla.github.io/server-side-tls/ssl-config-generator/

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

Another cause of this issue could be not properly including mimetypes in the http block, as shown here.

### Login loop without any clue in access.log, error.log, nor nextcloud.log

If you after fresh installation (Centos 7 with nginx) have problem with first login, you should as first check these files:

    tail /var/www/nextcloud/data/nextcloud.log
    tail /var/log/nginx/access.log
    tail /var/log/nginx/error.log

If you just see some correct requests in access log, but no login happens, you check access rights for php session and wsdlcache directory. Try to check permissions and execute change if needed:

    chown nginx:nginx /var/lib/php/session/
    chown root:nginx /var/lib/php/wsdlcache/
    chown root:nginx /var/lib/php/opcache/
