安装问题， 注册 404

安装完成了， 注册 404，

看了这个站的安装问题， 都说是 rewrite 没有开启， 但是我的已经开启了， 不知道哪里出了问题，

系统：ubuntu， 搬瓦工 虚拟主机

scola2@default:/etc/apache2$ sudo a2enmod rewrite

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        # For most configuration files from conf-available/, which are

        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
