Apache动态通配符主机用动态子域重写

Question

I'm currently in the process of converting an old apache vhost, where one is currently created for each new release, to a dynamic host that can handle all the subdomains so we don't have to create a new one all the time. I need some help! We're using apache v2.2.

目标

动态所有事物。拥有一个处理一组特定子域的所有重定向的虚拟主机。网址如下，请注意 sub1 和 branch 是动态并且可以是任何内容。

sub1.branch.sandbox.domain.com

其目录结构如下:

/var/www/vhosts/branch/sub1.branch.sandbox.domain.com

正如您在上面所看到的，目录结构将 branch 作为子目录，完整的 url 是另一个子目录的名称。

此外，网址中的 /images/ 需要转发到每个域的 shared-httpdocs/images。

我目前拥有的虚拟主机

<VirtualHost *:80>
        ServerName branch.sandbox.domain.com
        ServerAlias *.branch.sandbox.domain.com

        VirtualDocumentRoot /var/www/vhosts/branch/%0

        Options Indexes FollowSymLinks

        # Rewrite Engine Stuff Here
        RewriteEngine On

        DirectoryIndex index.php

        # Assets needs to be forwarded - currently not working
        RewriteCond %{REQUEST_URI} ^/(css|js|images)/.*
        RewriteRule .*$ /var/www/vhosts/%0/shared-httpdocs/%1$ [L]

        # The HTTP dispatcher - currently not working
        RewriteCond %{HTTP_HOST} ^(.*)\.branch\.sandbox\.domain\.com [NC]
        RewriteRule ^(.*)$ /var/www/vhosts/%1/applications/portal/dispatchers/http.php [L,QSA,NS,NE,NC]
</VirtualHost>

我正在尝试复制的旧主机

这是我尝试转换的旧虚拟主机。这太可怕了、太困惑了，我们的操作人员每次都必须创建一个新的 DNS 条目。真是笑话!我需要解决这个问题...

<VirtualHost *:80>
    # Notice how the stupid convention below will require a new DNS entry each time?
    ServerName sandbox.branch.domain.com
    ServerAlias sandbox.api.branch.domain.com

    DocumentRoot /var/www/vhosts/sandbox.branch.domain.com/applications/portal/httpdocs

    <Directory "/var/www/vhosts/sandbox.branch.domain.com/applications/portal/httpdocs">
            allow from all
            order allow,deny
            # Enables .htaccess files for this site
            #AllowOverride All

            RewriteEngine On

            # Rewrite all non-static requests to go through the webapp
            RewriteCond %{REQUEST_URI} ^/(css|js|images)/.*
            RewriteRule .* - [L]

            # Rewrite everything else to go through the webapp
            RewriteRule ^(.*)$ /dispatchers/http.php [QSA,L]

    </Directory>

    <Directory  "/var/www/vhosts/sandbox.branch.domain.com/applications/portal/dispatchers">
        allow from all
    </Directory>

    # Allow us to rewrite to the webapp without it being in the webroot
    Alias /dispatchers /var/www/vhosts/sandbox.branch.domain.com/applications/portal/dispatchers

    # Get shared/ to point to the shared static resources
    Alias /shared /var/www/vhosts/sandbox.branch.domain.com/shared-httpdocs

</VirtualHost>

每次我们有一个新分支时都需要一个新的 DNS 条目，因此我尝试通过提供动态子域虚拟主机(请参阅我迄今为止拥有的虚拟主机)来缓解这一问题。我已经从无法匹配 url 中的 /images/ 变成了永久重定向循环。

我怎样才能实现我的目标？我知道这有点复杂。如果我做不到，我只需要编写一个脚本，每次都会生成一个新的虚拟主机，但一个“正常工作”的动态脚本将是非常棒的。到目前为止我已经花了两天时间，我不是系统管理员。我们将非常感谢您的帮助。

我一直在使用的资源:

• mod_rewrite official docs - 使用 REWRITE_COND
显示诸如条件等基础知识
• Sub domain rewriting - 关于子域名重写的问题
• Asset rewriting - 另一个关于重写图像/css/js之类的问题，这似乎对我不起作用

这不是一个完整的答案，但太长了，无法发表评论。

重写规则中的 %0(%0 到 %9)是对最后一个 RewriteCond 中捕获的反向引用。在我看来，您想要的是主机名。而且你似乎错过了路径的“分支”部分。在资源重写中，您还丢弃了文件名部分。

# Assets needs to be forwarded - currently not working
RewriteCond %{REQUEST_URI} ^/(css|js|images)/(.*)
RewriteRule .*$ /var/www/vhosts/branch/%{HTTP_HOST}/shared-httpdocs/%1/%2$ [L]


# The HTTP dispatcher - currently not working
RewriteCond %{HTTP_HOST} ^(.*)\.branch\.sandbox\.domain\.com [NC]
RewriteRule ^(.*)$ /var/www/vhosts/branch/%{HTTP_HOST}/applications/portal/dispatchers/http.php [L,QSA,NS,NE,NC]

您还可以通过 RewriteLog 和 RewriteLogLevel 指令从 mod_rewrite 专用日志记录中获得调试帮助。

希望这能让您走得更远。
