虚拟主机的问题 apache 在 Windows - 请解释

这个问题从未发生过早。 (我多次尝试过), 但这一次

文件中定义的所有虚拟主机 virtual-hosts.conf 在安装目录中 apache, 在目录中发送浏览器 documentRoot 服务器 apache.

我用 Windows 7 使用最后一个版本 apache.

这些是定义的虚拟主机

NameVirtualHost *:80



#

# VirtualHost example:

# Almost any Apache directive may go into a VirtualHost container.

# The first VirtualHost section is used for all requests that do not

# match a ServerName or ServerAlias in any <virtualhost> block.

#

<virtualhost *:80="">

        ServerName dev.a.local

        ServerAlias dev.a.local

        DocumentRoot "D:/wwwroot/a/public"

        ErrorLog "logs/a.log"

        CustomLog "logs/a-access.log" common



        <directory "d:="" a="" public"="" wwwroot="">

                Options Indexes FollowSymLinks

                AllowOverride All

        # Controls who can get stuff from this server.

          Order allow,deny

                  Allow from all

                  DirectoryIndex index.php

        </directory>

</virtualhost>

<virtualhost *:80="">

        ServerName dev.b.local

        ServerAlias dev.b.local

        DocumentRoot "D:/wwwroot/b/public"

        ErrorLog "logs/b.log"

        CustomLog "logs/b-access.log" common



        <directory "d:="" b="" public"s="" wwwroot="">

                Options Indexes FollowSymLinks

                AllowOverride All

        # Controls who can get stuff from this server.

          Order allow,deny

                  Allow from all

                  DirectoryIndex index.php

        </directory>

</virtualhost>

我改变了文件 hosts 和补充

127.0.0.1 dev.a.local 

127.0.0.1 dev.b.local

当我试图访问 dev.a.local 或者 dev.b.local, 我被n重定向。 documentRoot apache, 定义 httpd.conf.

请帮忙。
