Lighttpd mod_rrdtool: Monitor The Load, Requests Per Seconds and Traffic

Posted on in Categories CentOS, Debian Linux, fedora linux, Hardware, Howto, lighttpd, Linux, Monitoring, RedHat/Fedora Linux, Ubuntu Linux last updated June 18, 2009

The round-robin database tool aims to handle time-series data like network bandwidth, temperatures, CPU load etc. The data gets stored in round-robin database so that system storage footprint remains constant over time. Lighttpd comes with mod_rrdtool to monitor the server load and other details. This is useful for debugging and tuning lighttpd / fastcgi server performance.

Lighttpd Control a Directory Listing With mod_dirlisting

Posted on in Categories Howto, lighttpd, Linux, Security, UNIX last updated March 8, 2008

Lighttpd web server will generate a directory listing if a directory is requested and no index-file was found in that directory. mod_dirlisting is one of the modules that is loaded by default and doesn’t have to be specified on server.modules to work.

Task: Enable Directory Listings Globally

Open lighttpd configuration file:
# vi /etc/lighttpd/lighttpd.conf
Append / modify
server.dir-listing = "enable"
OR
dir-listing.activate = "enable"
Save and close the file. Restart lighttpd:
# /etc/init.d/lighttpd restart
To disable directory listing, use:
dir-listing.activate = "disable"

Enable directory listing only for a directory

You can also enable or disable listing on selected url / directory combination. For example, display directory listing only for /files/:
$HTTP["url"] =~ "^/files($|/)" { server.dir-listing = "enable" }
OR
$HTTP["url"] =~ "^/files($|/)" { dir-listing.activate = "enable" }

Configure lighttpd alias (mod_alias)

Posted on in Categories Howto, lighttpd, Linux, UNIX last updated March 8, 2008

This lighttpd module provides for mapping different parts of the host filesystem in the document tree. You can use it for mapping various directories. For example cgi-bin directory mapped to /var/lib/cgi-bin. The alias module is used to specify a special document-root for a given url-subset.

Configuration

Open your lighttpd configuration file:
vi /etc/lighttpd/lighttpd.conf

Append/add mod_ alias to list of server modules:
server.modules += ( "mod_alias" )

Examples

Add cgi-bin alias for doamin theos.in
alias.url = ( "/cgi-bin/" => "/home/lighttpd/theos.in/cgi-bin/" )

Browse all documents installed at /usr/share/doc/ directory with following alias:
alias.url = ( "/docs/" => "/usr/share/doc/" )
alias.url += ( "/stats/" => "/home/theos.in/http/webalizer/" )

Open a browser and type url http://theos.in/docs/ or http://your-domain.com/docs/
