DZone Snippets: virtualhosting code

A tool to split log files by hostname

cspurrier (Craig Spurrier) — Tue, 15 Aug 2006 03:58:35 GMT

This script can be used to split a log file by the hostname in the request. It is designed for use with lighttpd virtual hosting, to prepare the log for Webalizer. It should be run with a cron job and CLI PHP.

$serverip = "127.0.0.1"; //Set to your IP address or default hostname, so requests without hostnames can be sorted 

$log = file_get_contents("/var/log/lighttpd/access.log"); //Log location

$fh = fopen("/var/log/lighttpd/access.log", 'w'); //Clear the log file

fclose($fh);

$lines = explode ("\n", $log);

foreach ($lines as $line){

$parts = explode (" ", $line);

$hostname = strtolower($parts[1]);

if (substr($hostname, 0, 4) == 'www.'){$hostname = substr($hostname, 4);} //Treat www. as the same as the www-less version

if ($hostname == '-'){$hostname = $serverip;} //Set a hostname for request without hostnames

$fh = fopen("/var/log/lighttpd/users/$hostname.access.log", 'a'); //Add the entry to the log for that hostname. Make sure this script can write to this location.

fwrite($fh, "$line\n");

fclose($fh);

create lighttpd conf files for vhosting

yo () — Mon, 26 Dec 2005 09:32:26 GMT

Creates lighttpd conf files like suggested on http://blog.lighttpd.net/articles/2005/11/25/simplify-your-configfiles-with-includes
simply add include "incl-domains.conf" to your main lighttpd.conf file



#!/usr/bin/env ruby -w

# light_conf_editor.rb

#

# Created by yo on 25.12.05.

#

#

# Description

# Creates lighttpd conf files

#

# usage: light_conf_editor add || remove domainname username

# example: light_conf_editor add bigcurl.com yo

# example: light_conf_editor remove bigcurl.com yo

Automatic sub-domains with lighttpd mapping to a specific folder

jason (Jason Hoffman) — Wed, 25 May 2005 18:35:22 GMT

Using lighttpd's mod_evhost with



# %% => % sign

# %0 => domain name + tld

# %1 => tld

# %2 => domain name without tld

# %3 => subdomain 1 name

# %4 => subdomain 2 name

#



$HTTP["host"] =~ "jasonhoffman.org" {

evhost.path-pattern        = "/home/jah/public/%3/"

}
