开启虚拟主机配置功能

sudo vi /etc/apache2/httpd.conf
在httpd.conf中找到“#Include /private/etc/apache2/extra/httpd-vhosts.conf”，去掉前面的“＃”，保存并退出。
sudo apachectl restart //重启Apache

配置虚拟主机

sudo vi /etc/apache2/extra/httpd-vhosts.conf //配置虚拟主机文件httpd-vhost.conf

##配置的格式参考
<VirtualHost *:80>
 #ServerAdmin webmaster@dummy-host2.example.com  //主机邮箱地址
 DocumentRoot "/usr/docs/dummy-host2.example.com"  //站点根目录
 ServerName dummy-host2.example.com  //站点虚拟域名
 ErrorLog "/private/var/log/apache2/dummy-host2.example.com-error_log"  //错误日志输出
 CustomLog "/private/var/log/apache2/dummy-host2.example.com-access_log" common
 <Directory "/usr/docs/dummy-host2.example.com"> //站点根目录   文件权限相关
             Options Indexes FollowSymLinks MultiViews
             AllowOverride None
             Require all granted
 </Directory>
</VirtualHost>
