apache 子域名自动与子域名同名的目录绑定

假设有域名domain.com，已经泛解析子域名*.domain.com到该主机的ip，web根目录为/var/www/，
在访问a.domain.com时，能自动绑定/var/www/a/目录，访问b.domain.com时，能自动绑定/var/www/b/目录

 

1、分别手动建立相应的virtualhost

主机配置文件vhost.conf

<VirutualHost *:80>
    DocumentRoot /var/www/
    ServerName domain.com
    ServerAlias *.domain.com
</VirtualHost>

以及/var/www/.htaccess文件

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com$
    RewriteCond %{REQUEST_URL} !^/%1/
    RewriteRule ^(.*)$ %1/$1
</IfModule>

此时不论以哪个域名访问，都会返回服务器内部错误

如果把RewriteCond %{REQUEST_URL} !^/%1/这行配置中的%1替换成具体的字符串，如a，这样的话，能够实现a.domain.com绑定到/var/www/a/目录，但是其他域名依然是/var/www/目录

 

2、任意主机名的虚拟主机

RewriteEngine on

RewriteMap    lowercase int:tolower

RewriteCond   "${lowercase:%{HTTP_HOST}}"   "^www\.([^.]+)\.example\.com$"
RewriteRule   "^(.*)" "/home/%1/www$1"

 

 

3、vhost_alias模块实现通配子域名

主机配置文件vhost.conf

<VirtualHost *:80>
ServerAdmin webmaster@localhost
 
ServerName test.loc
ServerAlias *.test.loc
 
# This will be the wildcarded document root. Any folder you create in /var/www/test will be automatically a subdomain name.
VirtualDocumentRoot /var/www/test/%-3
 
# For symlinking your projects and htaccesses to work
<Directory />
Options FollowSymLinks
AllowOverride All
</Directory>
 
ErrorLog /var/log/apache2/vhosts-error.log
 
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
 
CustomLog /var/log/apache2/vhosts-access.log combined
</VirtualHost>
