Tengine is an www-servers/nginx fork. It supports DSO module loading, meaning it can have external modules without the need to compile them in.

Installation

Shared & Static Modules

If you happen to want all modules installed dynamically, you, still, need to install some static modules. Make sure to add this to your /etc/portage/make.conf file:

   /etc/portage/make.conf - Tengine all-modules build

...
TENGINE_SHARED_MODULES_HTTP="access addition autoindex browser charset_filter empty_gif fastcgi flv footer_filter geoip image_filter limit_conn limit_req lua map memcached mp4 random_index referer reqstat rewrite scgi secure_link slice split_clients sub sysguard tfs trim_filter upstream_ip_hash upstream_least_conn upstream_session_sticky user_agent userid_filter uwsgi xslt"
TENGINE_STATIC_MODULES_HTTP="concat dav degradation geo gunzip gzip gzip_static perl proxy realip spdy ssi ssl stub_status upstream-rbtree upstream_check upstream_consistent_hash upstream_keepalive"
...

External Modules

Passenger is an easy method to serve ruby, python, node.js, and Meteor cms' or web applications.

If you want to run passenger:

   /etc/portage/make.conf - build the passenger module

TENGINE_EXTERNAL_MODULES_HTTP="passenger"

Then merge:

root # emerge tengine

Configuration

Files for configuration are located at /etc/tengine

The major differing point in tengine from nginx is that you have to specifically declare which modules are loaded. Available modules are located at /var/lib/tengine/modules.

   /etc/tengine/tengine.conf - DSO module statements

...
dso {
	load ngx_http_charset_filter_module.so;
	load ngx_http_fastcgi_module.so;
	load ngx_http_rewrite_module.so;
	load ngx_http_access_module.so; ## added because you want most likely use allow & deny on certain positions
}
...

Tengine

/etc/tengine/tengine.conf contains engine specific configurations.

Sites

/etc/tengine/sites-available/localhost has site specific configurations. Generally localhost is copied to domain.tld file formats in the /etc/tengine/sites-available/ directory.

Redirection

These days, it is usual to have anything on https to protect your users regarding login and privacy where it comes handy to automatically redirect requests from http which are often a result of the browsers autocompletion. To achieve that, we need a server listening on http and redirecting to our main server on https like this :

   /etc/tengine/sites-available/redir - redirection from http to https

server {
        server_name domain.tld;
        listen 80;
	return 302  https://www.domain.tld$request_uri;
}

PHP-FPM

Tengine does not natively support php, so we delegate that responsibility to php-fpm

   /etc/tengine/sites-available/localhost - fpm tcp/ip configuration

server {
        ...
	index index.php index.cgi index.htm index.html;
	location ~ \.php$ {
	        fastcgi_pass 127.0.0.1:9000;
		include fastcgi.conf;
        }
        ...
}

Passenger

To serve with passenger, change the root statement below to point to your rails application's public directory:

   /etc/tengine/sites-available/localhost - passenger configuration

passenger_root /usr/libexec/passenger/locations.ini;
passenger_ruby /usr/bin/ruby;

server {
        passenger_enabled on;
	passenger_app_env development;
	root /home/$USER/ror/public;
        ...
}

Passenger's app environments:

1. test
2. development
3. production

   Note

Anything the internet can touch should be in production mode.

Usage

To start the tengine server:

root # rc-update add tengine default
root # rc
