Apache Multiple VirtualDocumentRoot
提问by Ben
Using Apache2 on a Linux system is there a way to have multiple VirtualDocumentRoot using mod_vhost_alias?
在 Linux 系统上使用 Apache2 有没有办法使用mod_vhost_alias拥有多个 VirtualDocumentRoot ？
This is naming convention I am currently using and would like to continue to use:
这是我目前正在使用并希望继续使用的命名约定：
host directory
127.0.0.1 domain domain.com
127.0.0.1 sub.domain domain.com_sub
Then in my vhosts section of the httpd.conf I have:
然后在 httpd.conf 的 vhosts 部分中，我有：
NameVirtualHost 127.0.0.1
<VirtualHost 127.0.0.1>
VirtualDocumentRoot /var/www/%0.0.com
</VirtualHost>
<VirtualHost 127.0.0.1>
VirtualDocumentRoot /var/www/%2.0.com_%1
</VirtualHost>
The problem with this is when I visit sub.domain the Apache error log shows that it is looking for /var/www/sub.domain.com rather than /var/www/domain.com_test which leads me to believe it only reads the first rule and then fails, but what I would like it to do is use any document root that satisfies either of the two VirtualDocumentRoot rules.
问题是当我访问 sub.domain 时，Apache 错误日志显示它正在寻找 /var/www/sub.domain.com 而不是 /var/www/domain.com_test 这让我相信它只读取第一条规则然后失败，但我希望它做的是使用满足两个 VirtualDocumentRoot 规则之一的任何文档根。

Apache typically will pick the first virtual host whose ServerNameor ServerAliasmatches the host name provided in the HostHTTP header. In your case, since you have no ServerNamedirectives, Apache supposedly uses a reverse DNS lookup on the IP address to fake a server name, and presuming that the reverse DNS leads to domain.com, which doesn't match, Apache then defaults to the first virtual host. Sounds complicated, I know... the bottom line is, you should use ServerNameand ServerAliasto make the configuration explicit. Try something more like this:
Apache 通常会选择第一个虚拟主机，其ServerName或ServerAlias匹配HostHTTP 标头中提供的主机名。在您的情况下，由于您没有ServerName指令，Apache 应该在 IP 地址上使用反向 DNS 查找来伪造服务器名称，并假设反向 DNS 指向不匹配的 domain.com，然后 Apache 默认为第一个虚拟主机。听起来很复杂，我知道……底线是，您应该使用ServerName和ServerAlias使配置明确。尝试更像这样的事情：
NameVirtualHost 127.0.0.1
<VirtualHost 127.0.0.1>
ServerName domain.com
ServerAlias www.domain.com
VirtualDocumentRoot /var/www/%0
</VirtualHost>
<VirtualHost 127.0.0.1>
ServerName sub.domain.com
ServerAlias *.domain.com
VirtualDocumentRoot /var/www/%2.%3_%1
</VirtualHost>
That should use /var/www/domain.comfor http://domain.comand /var/www/www.domain.comfor http://www.domain.com, both of which are served by the first vhost, and /var/www/sub.domain.comfor http://sub.domain.com, /var/www/blah.domain.comfor http://blah.domain.com, and so on.
这应该使用/var/www/domain.com的http://domain.com和/var/www/www.domain.com对http://www.domain.com，这两者都是由第一虚拟主机服务，并/var/www/sub.domain.com为http://sub.domain.com，/var/www/blah.domain.com对于HTTP：// blah.domain.com等等。

You have to qualify the backreferences when you want to put a '.' in the file path. So you need to have it like this:
当您想放置一个 '.' 时，您必须限定反向引用。在文件路径中。所以你需要像这样：
VirtualDocumentRoot /var/www/%2.0.%3_%1

Regarding the OP and the issue with "/var/www/html" being set:
关于 OP 和设置“/var/www/html”的问题：
The problem I had to this was using %1 instead of %2. Here's my working example:
我遇到的问题是使用 %1 而不是 %2。这是我的工作示例：
ServerAlias www.*.org.au
UseCanonicalName Off
VirtualDocumentRoot /path/to/sites/%2/pub
Hope that helps someone!

I read the docs on "Directory Name Interpolation" in mod_vhost_alias docs.
我在mod_vhost_alias docs 中阅读了有关“目录名称插值”的文档。

I finally found a configuration that allows flexible subdomain creation.
我终于找到了一个允许灵活创建子域的配置。
See apache docs on mod_vhost_alias
请参阅mod_vhost_alias 上的apache 文档
If your root dev domain has 3 parts like dev.example.com you can use %-4+as a placeholder for everything before the root domain. If it has 4 parts, use %-5+.
如果您的根开发域有 3 个部分，例如 dev.example.com，您可以将其%-4+用作根域之前所有内容的占位符。如果它有 4 个部分，请使用%-5+.
<VirtualHost *:80>
VirtualDocumentRoot "/var/www/%-4+/webroot"
ServerName www.dev.example.com
ServerAlias *.dev.example.com
php_admin_value auto_prepend_file /var/www/setdocroot.php
</VirtualHost>
This way you can create a directory named /var/www/sub.domain/webrootand access it with the url sub.domain.dev.example.com.
通过这种方式，您可以创建一个名为/var/www/sub.domain/webrooturl的目录并访问它sub.domain.dev.example.com。
The line php_admin_value auto_prepend_file /var/www/setdocroot.phpfixes the docroot on some systems like OSX 10.9+
该行php_admin_value auto_prepend_file /var/www/setdocroot.php修复了某些系统上的 docroot，如 OSX 10.9+
Here is the content of setdocroot.php:
以下是内容setdocroot.php：
<?php
$_SERVER['DOCUMENT_ROOT'] = str_replace($_SERVER['SCRIPT_NAME'], '', $_SERVER['SCRIPT_FILENAME']);
?>
回答by Svetoslav Marinov
What I am noticing with this configuration is that $_SERVER['DOCUMENT_ROOT'] is pointing to /var/www/html and not to the vhost's doc root. weird.
我注意到这个配置是 $_SERVER['DOCUMENT_ROOT'] 指向 /var/www/html 而不是 vhost 的文档根。奇怪的。
