What distro are you using? Is this for Apache2?
Here is a template which you can use.
On my SuSE system I simple save the file in /etc/apache2/vhosts.d with the .conf extension to make sure it is included when Apache2 loads.
You could build in these directives into /etc/apache2/httpd.conf
<VirtualHost *:80>
ServerAdmin
webmaster@dummy-host.example.com
ServerName dummy-host.example.com
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
DocumentRoot /srv/www/vhosts/dummy-host.example.com
# if not specified, the global error log is used
ErrorLog /var/log/apache2/dummy-host.example.com-error_log
CustomLog /var/log/apache2/dummy-host.example.com-access_log combined
# don't loose time with IP address lookups
HostnameLookups Off
# needed for named virtual hosts
UseCanonicalName Off
# configures the footer on server-generated documents
ServerSignature On
# Optionally, include *.conf files from /etc/apache2/conf.d/
#
# For example, to allow execution of PHP scripts:
#
# Include /etc/apache2/conf.d/php5.conf
#
# or, to include all configuration snippets added by packages:
# Include /etc/apache2/conf.d/*.conf
# ScriptAlias: This controls which directories contain server scripts.
# ScriptAliases are essentially the same as Aliases, except that
# documents in the realname directory are treated as applications and
# run by the server when requested rather than as documents sent to the client.
# The same rules about trailing "/" apply to ScriptAlias directives as to
# Alias.
#
ScriptAlias /cgi-bin/ "/srv/www/vhosts/dummy-host.example.com/cgi-bin/"
# "/srv/www/cgi-bin" should be changed to whatever your ScriptAliased
# CGI directory exists, if you have one, and where ScriptAlias points to.
#
<Directory "/srv/www/vhosts/dummy-host.example.com/cgi-bin">
AllowOverride None
Options +ExecCGI -Includes
Order allow,deny
Allow from all
</Directory>
# UserDir: The name of the directory that is appended onto a user's home
# directory if a ~user request is received.
#
# To disable it, simply remove userdir from the list of modules in APACHE_MODULES
# in /etc/sysconfig/apache2.
#
<IfModule mod_userdir.c>
# Note that the name of the user directory ("public_html") cannot simply be
# changed here, since it is a compile time setting. The apache package
# would have to be rebuilt. You could work around by deleting
# /usr/sbin/suexec, but then all scripts from the directories would be
# executed with the UID of the webserver.
UserDir public_html
# The actual configuration of the directory is in
# /etc/apache2/mod_userdir.conf.
Include /etc/apache2/mod_userdir.conf
# You can, however, change the ~ if you find it awkward, by mapping e.g.
#
http://www.example.com/users/karl-heinz/ --> /home/karl-heinz/public_html/
#AliasMatch ^/users/([a-zA-Z0-9-_.]*)/?(.*) /home/$1/public_html/$2
</IfModule>
#
# This should be changed to whatever you set DocumentRoot to.
#
<Directory "/srv/www/vhosts/dummy-host.example.com">
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
#
# The Options directive is both complicated and important. Please see
#
http://httpd.apache.org/docs-2.2/mod/core.html#options
# for more information.
#
Options Indexes FollowSymLinks
#
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
#
AllowOverride None
#
# Controls who can get stuff from this server.
#
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
Apache2 n00b.
