apache安装完默认是不开启虚拟服务器的，如果希望在本地apache上面配置虚拟服务器，类似于在网上买的虚拟主机，可以按照以下步骤进行配置：
1,修改本机的hosts文件，如下
示例：
127.0.0.1 localhost
127.0.0.1 xlb.com
127.0.0.1 xlb2.com
2,打开Apache的安装目录，找到httpd.conf文件，分别去掉下面两行文字前面的#号。
LoadModule vhost_alias_module modules/mod_vhost_alias.so
去掉#意思是启用apache的虚拟主机功能。
Include conf/extra/httpd-vhosts.conf
去掉这一行的#意思是从conf/extra/httpd-vhosts.conf这个文件导入虚拟主机配置。
3，打开extra目录内的httpd-vhosts.conf文件，把默认的配置
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "/www/docs/dummy-host.localhost"
ServerName dummy-host.localhost
ServerAlias http://www.dummy-host.localhost/
ErrorLog "logs/dummy-host.localhost-error_log"
CustomLog "logs/dummy-host.localhost-access_log common"
</VirtualHost>
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "/www/docs/dummy-host2.localhost"
ServerName dummy-host2.localhost
ErrorLog "logs/dummy-host2.localhost-error_log"
CustomLog "logs/dummy-host2.localhost-access_log common"
</VirtualHost>
改成自己想要的目录和域名
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "D:/wamp/www/"
ServerName localhost
ServerAlias localhost
ErrorLog "logs/localhost-error_log"
</VirtualHost>
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "D:/wamp/www/web/"
ServerName test.com （填主域名）
ServerAlias *.test.com (这里的服务器别名可以支持泛解析，即所有的子域名都可以解析绑定到该虚拟主机)
ErrorLog "logs/localhost-error_log"
</VirtualHost>
如果 弄完之后 出现403错误 那 在httpd.conf里找到：
<Directory />
Options FollowSymLinks ExecCGI Indexes
AllowOverride None
Order deny,allow
Deny from all
Satisfy all
</Directory>
更改为
<Directory />
Options FollowSymLinks ExecCGI Indexes
AllowOverride None
# Order deny,allow
# Deny from all
# Satisfy all
</Directory>
