Nginx [engine x] is an HTTP and reverse proxy server, as well as a mail proxy server, written by Igor Sysoev. The nginx project started with a strong focus on high concurrency, high performance and low memory usage. It is licensed under the 2-clause BSD-like license and it runs on Linux, BSD variants, Mac OS X, Solaris, AIX, HP-UX, as well as on other *nix flavors. It also has a proof of concept port for Microsoft Windows.

The following is community-contributed documentation on Nginx configuration. Amendmends and additions are welcome.

Nginx configuration

PHP-FPM

Nginx is usually configured to interface with PHP via php-fpm. This is both fast and robust.

php.ini

Typically the php-fpm daemon with have it's own php.ini e.g. in debian it is /etc/php5/fpm/php.ini. The following setting is required,

php.ini

cgi.fix_pathinfo=0

Nginx

fcig_params

The standard fastcgi_params file included in Nginx is not compatible with moodle; save a new fastcgi_params file with the following parameters,

fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;

fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;

fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;

server configuration

Add the following 'slash arguments' compatible (see Using slash arguments) 'location' block to your vhosts 'server' configuration in your nginx configuration.

nginx.conf location:

location ~ [^/]\.php(/|$) {
    # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
    fastcgi_split_path_info  ^(.+\.php)(/.+)$;
    include                  fastcgi_params;
    fastcgi_index            index.php;
    fastcgi_pass             127.0.0.1:9000;
}
