nginx-guess-mime

Introduction

This module inserts a body filter into the nginx chain that will guess the MIME type of a file if the default file-extension guessing fails.

The code is commented, so it may be used as an example of a simple nginx module, too.

Dependencies

nginx-guess-mime uses libmagic to guess the MIME type. Please install libmagic-dev or similar to compile.

Installation

nginx

This module is not bundled with nginx. You will have to manually compile nginx for this module to function:

1. Clone this repository
2. Download nginx source
3. Configure nginx to use this module (e.g. ./configure --add-module=/path/to/nginx-guess-mime)
4. Build nginx as usual (likely make)
5. Install nginx to the correct place (likely sudo make install)

tengine

This module is not bundled with tengine. You will have to manually compile the module for this module to function. Luckily, tengine has a tool to make it rather easy.

After cloning, just run the dso_tool to install the module to the right place.

/path/to/dso_tool --add-module=/path/to/nginx-guess-mime

On my system, tengine is installed in /opt/tengine/sbin, so I would run /opt/tengine/sbin/dso_tool.

See here for more information.

Usage

This module registers a single directive, guess_mime, that can be turned on or off. To enable it globally, write guess_mime on; in the http block. To enable or disable per-location write the appropriate directive and argument.

An example configuration where the same files are served, but on port 9006, guess_mime is enabled, but on port 9005, guess_mime is not, can be seen below:

http {
    guess_mime on;

    server {
        listen 9005;
        root /var/www;
        guess_mime off;
    }

    server {
        listen 9006;
        root /var/www;
    }
}
