ubuntu中drupal localhost到域名

我已经在本地机器上安装了drupal Buntu 12.04。当我点击http//localhost/drupal时，它成功运行。我想将localhost更改为我的网站。我曾尝试过谷歌it，但解决方案直到现在都不起作用。我的/etc/apache2/sites enabled/drupal如下所述

<VirtualHost 127.0.0.1:80>
ServerAdmin webmaster@localhost

DocumentRoot /var/www
<Directory />
    Options FollowSymLinks
    AllowOverride None
</Directory>
<Directory /var/www/>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride None
    Order allow,deny
    allow from all
</Directory>

ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
    AllowOverride None
    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    Order allow,deny
    Allow from all
</Directory>

ErrorLog ${APACHE_LOG_DIR}/error.log

# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn

CustomLog ${APACHE_LOG_DIR}/access.log combined

Alias /doc/ "/usr/share/doc/"
<Directory "/usr/share/doc/">
    Options Indexes MultiViews FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all
    Allow from 127.0.0.0/255.0.0.0 ::1/128
</Directory>

</VirtualHost>

作为Drupal用户，我强烈推荐Acquidev桌面作为运行Drupal的一种方式。它有许多功能，包括命名您的域名

我可以用德鲁什吗？我已经安装了drupal，在上面安装drush可以吗？
