我已经通过这种方法设置了Apache 2虚拟主机。

下 /etc/apache2/sites-available 我创造了一个 dummy_site_1.conf

dummy_site_1.conf

<VirtualHost local.dummy_site_1:80>
    ServerName local.dummy_site_1
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/dummy_site_1
    ErrorLog /var/log/apache2/dummy_site_1__error.log
    TransferLog /var/log/apache2/dummy_site_1__access.log
    <Directory /var/www/dummy_site_1>
        AllowOverride Options Limit None
        Options -Indexes FollowSymLinks
    Order deny,allow
    Allow from all
    </Directory>
    DirectoryIndex index.php
    #DISABLE HTTP TRACE
    #RewriteEngine On
    #RewriteCond %{REQUEST_METHOD} ^TRACE
    #RewriteRule .* - [F]
</VirtualHost>

我也添加了这一行 httpd.conf：

ServerName local.dummy_site_1

现在所有人都在使用这个设置，我打字 local.dummy_site_1 在URL中，我可以看到我的网站。

问题是当我尝试添加另一个站点配置时 dummy_site_2.conf 并创建大约相同的设置

dummy_site_2.conf

<VirtualHost local.dummy_site_2:80>
    ServerName local.dummy_site_2
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/dummy_site_2
    ErrorLog /var/log/apache2/dummy_site_2__error.log
    TransferLog /var/log/apache2/dummy_site_2__access.log
    <Directory /var/www/dummy_site_2>
        AllowOverride Options Limit None
        Options -Indexes FollowSymLinks
    Order deny,allow
    Allow from all
    </Directory>
    DirectoryIndex index.php
    #DISABLE HTTP TRACE
    #RewriteEngine On
    #RewriteCond %{REQUEST_METHOD} ^TRACE
    #RewriteRule .* - [F]
</VirtualHost>

我也添加了这一行 httpd.conf：

ServerName local.dummy_site_2

我收到此错误：

user@host:/etc/apache2$ sudo /etc/init.d/apache2 restart
 * Restarting web server apache2                                                                                                                                                                     [Wed Sep 15 14:00:43 2010] [error] (EAI 5)No address associated with hostname: Could not resolve host name local.dummy_site_2 -- ignoring!
 ... waiting [Wed Sep 15 14:00:44 2010] [error] (EAI 5)No address associated with hostname: Could not resolve host name local.dummy_site_2 -- ignoring!

为什么？我配置错了吗？

你不需要' ServerName local.dummy_site_2 '在httpd.conf中，所以拿出来，但添加这个：

NameVirtualHost ip-address-of-server:80

例如：NameVirtualHost 192.168.1.10:80

完成更改后，您需要重新启动Apache。

如果事情仍然没有按预期工作，请在服务器名称行下面的每个虚拟主机配置文件中添加一行，如下所示：

ServerName local.dummy_site_1
ServerAlias *.local.dummy_site_1 local.dummy_site_1

和

ServerName local.dummy_site_2
ServerAlias *.local.dummy_site_2 local.dummy_site_2

再次，重新启动Apache以检查更改。

编辑：愚蠢的我 - 刚刚发现问题的另一部分 - 所有的VirtualHost声明应该使用虚拟服务器的IP地址 - 例如：

<VirtualHost 192.168.1.10:80>

实际上，您可以完全删除IP地址和/或站点名称。

例：

NameVirtualHost *:80
NameVirtualHost *:443

<VirtualHost *:80>
ServerAdmin emailaddress@domain.tld
DocumentRoot "/path/to/vhost/documents"
ServerName servername.domain.tld
ServerAlias serveralias.domain.tld
ErrorLog "/path/to/logfiles/servername.domain.tld-error.log"
CustomLog "/path/to/logfiles/servername.domain.tld-access.log" common
<Directory "/path/to/vhost/documents">
allow from all
Option +Indexes
</Directory>
</VirtualHost>

<VirtualHost *:443>
ServerAdmin emailaddress@domain.tld
DocumentRoot "/path/to/vhost/documents"
ServerName servername.domain.tld
ServerAlias serveralias.domain.tld
SSLEngine On
SSLCertificateFile /path/to/certificate/file.cert
SSLCertificateKeyFile /path/to/certificate/file.key
ErrorLog "/path/to/logfiles/servername.domain.tld-error.log"
CustomLog "/path/to/logfiles/servername.domain.tld-access.log" common
<Directory "/path/to/vhost/documents">
allow from all
Option +Indexes
</Directory>
</VirtualHost>

（现在，让我们举一个vhost结合mod_proxy的例子; ip = numeric-octet，下面）

<VirtualHost *:80>
ProxyPreserveHost Off
ProxyPass / http://ip.ip.ip.ip/
ProxyPassReverse / http://ip.ip.ip.ip/
ServerName servername.domain.tld
</VirtualHost>

基本上，只要您的DNS信息与您配置的虚拟主机匹配，那么它应该都可以正常工作。
