Question

我在ubuntu 10.4上使用apache2 + tomcat。我正在tomcat服务器上运行，该服务器上有8080监听的webapps

“HTTP：//内部：8080 /目录/名称-privatewebapp /”
的 “http：//内部：8080 /目录/名称-publicwebapp /”

面向外部的Apache服务器代理对域的请求。

我想将“subdomain”重新映射为“domain.com/subdomain”，因此任何其他请求都会被代理到相应的路径/ webapp

web.john-doe.domain.com  --->  www.domain.com/web/john-doe 


http://www.john-doe.com  --->   www.domain.com/web/john-doe
http://www.foo-bar.com  --->  www.domain.com/web/foo-bar

我无法单独使用mod_rewrite。我一直在调查 mod_proxy，mod_proxy_ajp和mod_rewrite

我想要服务器

从域中抓取子域名
确保子域名不是www，w或ww
在重写
如果目录不存在则保留为野域
最后，如果目录存在实际重写

我检查了几个链接，并在http://www.askapache.com/htaccess/crazy-advanced-mod_rewrite-tutorial.html

没有成功。

我跟着这个 illumin-it.servehttp.com/wordpress/2012/01/redirecting-to-as-using-apache/ 有点成功。

但是，我希望服务器能够通过重写和代理动态执行此操作，而无需为每个子域编辑vhost。

这是我更新的vhost文件

我也试过...... http://httpd.apache.org/docs/2.0/rewrite/rewrite_guide.html

假设www.username.host.com/anypath内部映射到www.host.com/home/username/anypath

由于网站的应用程序是用Java服务器创建的，我认为单独的mod_rewrite不起作用。

虚拟用户主机

RewriteCond   %{HTTP_HOST}                 ^www\.[^.]+\.host\.com$
RewriteRule   ^(.+)                        %{HTTP_HOST}$1          [C]
RewriteRule   ^www\.([^.]+)\.host\.com(.*) /home/$1$2

Answer 1

在类似的情况下，我通常把这样的东西放到webroot中的.htaccess（/var/www/.htaccess）：

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_HOST} subdomain1.domain.com
RewriteCond %{REQUEST_URI} !^/subdomain1
RewriteRule ^(.*)$ one/$1 [L]

RewriteCond %{HTTP_HOST} subdomain2.domain.com
RewriteCond %{REQUEST_URI} !^/subdomain2
RewriteRule ^(.*)$ two/$1 [L]

RewriteRule    ^$ /    [L]
RewriteRule    (.*) /$1 [L]
</IfModule>

所以我有

subdomain1.servername.com -> /var/www/subdomain1
subdomain2.servername.com -> /var/www/subdomain2 
servername.com -> /var/www

也许这会对你有帮助吗？

Answer 2

你的第一套规则：

#redirect domain.com to www.domain.com
RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
RewriteRule .+ http://www.domain.com%{REQUEST_URI} [R=301,NC]

如果您没有空请求，则取代您拥有的任何子域。第二套规则接近你想要的。但是它们循环并且它们不会将多个子域条目转换为目录路径，因此请尝试将这组规则首先：

# Prevent looping this rule
RewriteCond %{ENV:REDIRECT_STATUS} !200
RewriteCond %{HTTP_HOST} !www.domain.com$ [NC]
RewriteCond %{HTTP_HOST} ^(www\.)?([a-z0-9.-]+).domain.com$ [NC]
RewriteRule (.*) /%2/$1 [L]

# change the "." in the path to "/"
RewriteRule ^(.*)\.(.*)/(.*)$ /$1/$2/$3 [L]

然后将您的“非www到www”规则更改为此（并按照上述规则）：

#redirect domain.com to www.domain.com
RewriteCond %{HTTP_HOST} !^domain\.com$ [NC]
RewriteRule ^ http://www.domain.com%{REQUEST_URI} [R=301,NC]
