Instalar lighttpd 1.5 con soporte async IO

Instalar libreria libaio

apt-get install libaio-dev

Bajamos la última versión de la versión 1.5 de lighttpd (no vale 1.4)

Podemos consultar las versiones en: http://blog.lighttpd.net/articles/tag/1.5.0

wget http://www.lighttpd.net/download/lighttpd-1.5.0-r1992.tar.gz

Instalamos herramientas para descomprimir (si fuera necesario)

apt-get install zip unzip tar

apt-get install libpcre3 libpcre3-dev

Descomprimimos

tar -zxvf lighttpd-1.5.0-r1992.tar.gz

Instalamos libreria glib

apt-get install libglib2.0

Configuramos, activando el soporte para el async I/O

./configure --with-linux-aio

make

make install

Preparamos el fichero de configuración y arranque por defecto al inicio.

sed -e 's/FOO/lighttpd/g' doc/rc.lighttpd > /etc/init.d/lighttpd

chmod a+rx /etc/init.d/lighttpd

update-rc.d lighttpd defaults

Copiamos el fichero de configuración a /etc/lighttpd/lighttpd.conf

Además de todos los parámetros necesarios, es importante activar la directiva de escritura asíncrona.

server.network-backend = "linux-aio-sendfile"

No está de más editar y revisar el fichero /etc/init.d/lighttpd creado, para asegurar que las rutas a los ejecutables/configuraciones son correctas.

Each Goliath request is executed in its own Ruby fiber and all asynchronous I/O operations can transparently suspend and later resume the processing without requiring the developer to write any additional code. Both request processing and response processing can be done in fully asynchronous fashion: streaming uploads, firehose API's, request/response, and so on.

A non-blocking async web-server written in Ruby, with quite good performance numbers.

Looks extra cool, can't wait to play with it on the new FS! API.
