Lighttpd’s default document root is /var/www, and the configuration file is /etc/lighttpd/lighttpd.conf. Additional configurations are stored in files in the /etc/lighttpd/conf-available directory. These configurations can be enabled with the lighttpd-enable-mod command which creates a symlink from the /etc/lighttpd/conf-enabled directory to the appropriate configuration file in /etc/lighttpd/conf-available. You can disable configurations with the lighttpd-disable-mod command.

1. Installation

sudo apt-get install lighttpd
# cat /etc/lighttpd/lighttpd.conf
# dir /etc/lighttpd/conf-available
Security Warning

Your data directory and files are probably accessible from the internet because
the .htaccess file does not work. For information how to properly configure your
server, please see the documentation.

2. Disable Lighttpd

sudo service lighttpd stop
sudo update-rc.d lighttpd disable

3. Enable Lighttpd

sudo update-rc.d lighttpd enable
sudo service lighttpd start
