.htaccess 多个加载域，一个htaccess文件

比如说，我的根域名是main.com，我有两个附加域：addon1.com和addon2.com

我的脚本已经准备好，我可以看到我的网站，如下所示：

    www.main.com/show.php?domain=addon1.com 

但是，我想要的是通过他们的域显示网站。我的意思是，当我打开addon1.com时，我想看到show.php？domain=addon1.com的输出。此外，这两个域作为附加域添加，其目录为：

    main.com/addon1.com/
    main.com/addon2.com/

我将htaccess文件写入根文件夹（main.com/.htaccess）

但我得到了500的间隔误差。有什么建议吗

提前感谢。

您的规则正在循环。php

/show.php

将通过重写引擎返回并无限循环。您需要添加条件，以便它们不会循环：

RewriteCond %{HTTP_HOST} ^www\.addon1\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/show.php
RewriteRule ^(.*)$ /show.php?domain=addon1.com&$1

RewriteCond %{HTTP_HOST} ^www\.addon2\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/show.php
RewriteRule ^(.*)$ /show.php?domain=addon2.com&$1

您需要包括“RewriteBase”以提供帮助

# tell mod_rewrite to activate and give base for relative paths
  Options +FollowSymLinks
  RewriteEngine on
  RewriteBase   /

# for the active site in hosting root folder,
# tell it not to look for a subfolder by skipping next rule
  RewriteCond %{HTTP_HOST}   ^(www\.)?main\.com [NC]
  RewriteRule ^(.*)$         - [S=1]

# the domain-name = sub-folder automation
# thus addon-domain.com in /addon-domain(\.com)?/
  RewriteCond %{HTTP_HOST}   ([^.]+)\.com
  RewriteCond %{REQUEST_URI} !^/%1
  RewriteRule ^(.*)$         %1/$1 [L]

# to answer your question swap the above 
# domain-name = sub-folder automation for this rule
  RewriteCond %{HTTP_HOST}   ([^.]+)\.com$ [NC]
  RewriteCond %{REQUEST_URI} !^/show.php
  RewriteRule ^(.*)$         /show.php?domain=%1&$1 [L]
# although, the above line may require this instead
  RewriteRule .              main.com/show.php?domain=%1&$1 [L]

谢谢你的回答。但是它试图加载main.com/addon1.com/show.php，show.php位于根文件夹（main.com/show.php）中。

# tell mod_rewrite to activate and give base for relative paths
  Options +FollowSymLinks
  RewriteEngine on
  RewriteBase   /

# for the active site in hosting root folder,
# tell it not to look for a subfolder by skipping next rule
  RewriteCond %{HTTP_HOST}   ^(www\.)?main\.com [NC]
  RewriteRule ^(.*)$         - [S=1]

# the domain-name = sub-folder automation
# thus addon-domain.com in /addon-domain(\.com)?/
  RewriteCond %{HTTP_HOST}   ([^.]+)\.com
  RewriteCond %{REQUEST_URI} !^/%1
  RewriteRule ^(.*)$         %1/$1 [L]

# to answer your question swap the above 
# domain-name = sub-folder automation for this rule
  RewriteCond %{HTTP_HOST}   ([^.]+)\.com$ [NC]
  RewriteCond %{REQUEST_URI} !^/show.php
  RewriteRule ^(.*)$         /show.php?domain=%1&$1 [L]
# although, the above line may require this instead
  RewriteRule .              main.com/show.php?domain=%1&$1 [L]
