1 在配置文件中开启虚拟配置
	# Virtual hosts
Include /private/etc/apache2/extra/httpd-vhosts.conf ,去除前面的#
	
2 打开Include /private/etc/apache2/extra/httpd-vhosts.conf
① 注释或删除默认配置
② 以下是我新增
	    DocumentRoot "/Users/jackwoo/wwwroot/meal"
    ServerName www.meal.com
    ErrorLog "/private/var/log/apache2/meal-error_log"
    CustomLog "/private/var/log/apache2/meal-access_log" common
    
        Require all granted
    
	
注意:apache 2.4以上版本中需要在目录下面添加 Require all granted,否则无论怎么访问都是403。
