报此错，是虚拟主机没配置好；修改虚拟主机配置文件中到第二个AllowOverride中到none改为all
报此错，开重写功能；命令：a2enmod rewrite;然后重启服务器
1.建立apache虚拟主机
/etc/apache2/sites-available
cp default www.test.com
cp default test.com
mkdir /var/www/test.com
a2ensite www.test.com
a2ensite test.com
(ln -s etc/apache2/sites-available/www.test.com /etc/apache2/sites-enabled/ )
/etc/init.d/apache2 restart
2.建立nginx虚拟主机
cd /etc/nginx/sites-available
cp default www.test.com
ln -s /etc/nginx/sites-available/www.test.com /etc/nginx/sites-enabled/www.test.com
sudo /etc/init.d/nginx restart
3.数据库
通过权限->添加新用户-> 创建与用户同名的数据库并授予所有权限
<VirtualHost *:80>
ServerAdmin webmaster@localhost
