• create the file:

  /etc/apache2/mods-available/vhost_hash_alias.conf

• Copy this in the vhost_hash_alias.conf file:

  # mod_vhost_hash_alias have to be enabled for each virtual host (catch-all)
  #
  HashEnable On
  
  #
  # Digest algorithm to use:
  # CRC32, ADLER32, MD5, SHA1, SHA256, or other types
  # supported by the module and libmhash
  #
  
  HashType md5
  
  #
  # The output encoding (rfc3548) of hash result
  # hexa, base16_low, base16_up, base32_low, base32_up, base64_ufs,
  #
  HashEncoding hexa
  
  #
  # Number of characters to use to build the document root
  # The hash string is truncated to this length

  HashAddAliasPrefix www ftp

• load the module on apache2

  a2enmod vhost_hash_alias

then reload apache2

  /etc/init.d/apache2 reload

This is an example of virtualhost for all website insite vhffs

put this in /etc/apache2/site-available/vhffs

<VirtualHost *>
      ServerAdmin webmaster@localhost
      DocumentRoot /data/web
      HashEnable On
      <Directory /data/web/>
              Options -ExecCGI Indexes FollowSymLinks +Includes MultiViews
              IndexIgnore */.quota */.*passw* */.htaccess
              IndexOptions NameWidth=*
              AllowOverride All
              order allow,deny
              allow from all
              RewriteEngine on
      </Directory>
      ErrorLog /var/log/apache2/sites-error.log
      LogFormat "%V %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" vhffs
      CustomLog /data/logs/web/incoming/{SERVER_NAME}/vhffs.log vhffs
      # Possible values include: debug, info, notice, warn, error, crit,
      # alert, emerg.
      LogLevel warn
      ServerSignature On
      Alias /icons/ "/usr/share/apache2/icons/"
      <Directory "/usr/share/apache2/icons">
          Options Indexes MultiViews
          AllowOverride None
          Order allow,deny
          Allow from all
      </Directory>
</VirtualHost>

Now, just run

  a2ensite vhffs

To avoid the URL to be hashed by the vhost hash alias module, you must insert the following code in the config:

 <VirtualHost *:80>
         [...]
         HashEnable Off
         [...]
 </VirtualHost>

Reference: http://www.suphp.org/

The configuration suphp file is

/etc/suphp/suphp.conf

Main modifications are:

docroot=/data/web

allow_file_group_writeable=true

allow_directory_group_writeable=true

check_vhost_docroot=false

min_uid=10000

min_gid=10000

In the virtual host config, insert

<IfModule mod_suphp.c>
      AddHandler x-httpd-php .php .php3 .php4 .php5 .phtml
      suPHP_AddHandler x-httpd-php
      suPHP_Engine on
</IfModule>

Then activate the module suphp:

a2enmod suphp
