請google一下apache和虛擬主機，

例如以下內容
配置虛擬主機

1.
在 sites-available/ 目錄下建立新的檔案填寫此虛擬主機的配置指令
2.
使用 a2ensite 命令啟用虛擬主機； 使用 a2dissite 命令停用虛擬主機

例如要建立一個基於埠的虛擬主機，要執行如下的步驟：

S1. 修改 /etc/apache2/ports.conf 檔案新增一個新的監聽埠

Listen 80
Listen 8080

/etc/apache2/ports.conf

S2. 在 sites-available/ 目錄下建立新的檔案 192.168.0.222-8080，新增如下的配置

<VirtualHost 192.168.0.222:8080>
ServerAdmin

[email protected]


<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>


DocumentRoot /home/www/192.168.0.222-8080
<Directory /home/www/192.168.0.222-8080/>

Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny

allow from all
</Directory>

ErrorLog /var/log/apache2/error.log
LogLevel warn

CustomLog /var/log/apache2/access.log combined
ServerSignature On
</VirtualHost>

/etc/apache2/sites-available/192.168.0.222:8080

S3. 建立 /home/www 目錄和 index 檔案

sudo mkdir -p /home/www/192.168.0.222-8080
sudo touch /home/www/192.168.0.222-8080/index.php

S4. 使用 a2ensite 命令啟用虛擬主機

sudo a2ensite 192.168.0.222-8080

S5. 重新啟動 Apache

sudo /etc/init.d/apache2 restart

以下是一個例項

ports.conf 檔案內容 例

# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz

#如果開多個虛擬主機,所有的NameVirtualHost,都應該設定為以下一樣,或不寫
#不然會錯 如 *:3008 has no VirtualHosts
NameVirtualHost *:80

#每增加一個埠,就增加一條 Listen 埠
Listen 3008
Listen 8080

<IfModule mod_ssl.c>
    # If you add NameVirtualHost *:443 here, you will also have to change
    # the VirtualHost statement in /etc/apache2/sites-available/default-ssl
    # to <VirtualHost *:443>
    # Server Name Indication for SSL named virtual hosts is currently not
    # supported by MSIE on Windows XP.
    Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    Listen 443
</IfModule>

在sites-available增加一個檔案,訪問時輸入 http://IP:8080/labelhttp/,這樣,非網頁檔案便可下載

內容如下(內容仿default)

只改動了三個地方

 Alias /labelhttp /home/ftp/users/labelhttp

 DocumentRoot /home/ftp/users/labelhttp

 <Directory /home/ftp/users/labelhttp/>

詳細其他內容如下

        Alias /labelhttp /home/ftp/users/labelhttp

        DocumentRoot /home/ftp/users/labelhttp
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /home/ftp/users/labelhttp/>
                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>
