History: InstallVirtualHosting

I just modifed the source for virtual hosting enabled for all the tikis I need. Here is how I proceeded (waiting for more writing efforts for a decent documentation).

let's host 3 domains
feu.org is a community website
localis.org is a developpers website
cynt.org is a personnal website
tikiwiki.org is a free software development community

I setup 4 databases, dumping content from db/tiki.sql and db/tiki_1.6-1.7.sql
call them tiki_feu, ))tiki_localis((, tiki_cynt and tiki_org

now here is my virtualhost settings (I striped rewrite rules stuff that you can find elsewhere). where :

IP is your server IP or * if you use the ))NameVirtualHost(( directive
DOMAIN is your domain name (feu.org for example)
DOCROOT is where you have put your tikiwiki source tree (/usr/local/tikiwiki for example)

<Directory DOCROOT>
Order allow,deny
Allow from all
</Directory>

# put one block like that per domain to host
<VirtualHost IP>
  ServerName DOMAIN
  ServerAlias www.DOMAIN
  DocumentRoot DOCROOT
  ErrorLog /var/log/apache/DOMAIN-error_log
  Customlog /var/log/apache/DOMAIN-access_log combined
  php_flag magic_quotes_gpc Off
  php_value "include_path" ".:lib:lib/pear:/usr/share/pear"
  <FilesMatch "\.(bak|inc|lib|sh|sql|tpl)$">
    order deny,allow
    deny from all
  </FilesMatch>
  <FilesMatch "^\.#">
    order deny,allow
    deny from all
  </FilesMatch>
</VirtualHost>

then I create some more cache directories:
(that operation can be conducted by running
setup_virtual.sh, just think to edit that file to
hardcode domain names)

mkdir templates_c/feu
mkdir templates_c/localis
mkdir templates_c/cynt
mkdir templates_c/tiki
mkdir modules/cache/feu
mkdir modules/cache/localis
mkdir modules/cache/cynt
mkdir modules/cache/tiki
chown -R www-data:mose template_c modules/cache

Now setup the conf for tikiwikis:
edit file /usr/local/tikiwiki/db/local.php
(there are some commented tips in file db/tiki-db.php)
and put something like that (adapt it to your context):

<?php
  $host_tiki   = 'localhost';
  $user_tiki   = 'tiki';
  $pass_tiki   = 'tiki';

  if (($_SERVER["SERVER_NAME"] == "localis.org") or ($_SERVER["SERVER_NAME"] == "www.localis.org")) {
    $dbs_tiki    = 'tiki_localis';
    $tikidomain  = 'localis';
  } elseif .... {
 
    ....

  } else {
    # do you have a default setting
    $dbs_tiki    = 'tiki_feu';
    $tikidomain  = 'feu';

  }
?>

Here is done. for my own convenience I also setup a directory local/ with one subdir for each domain for disk storage of contents (set in admin panels).
Templates are common, one theme per site is maybe the right solution.

Here is it. any suggestion is welcome, and bugfixes are enjoyed !
