修改目录

输入：vim /etc/apache2/sites-available/000-default.conf

修改：<VirtualHost *:520> 
(注意这里要改成自己修改后的端口，没修改就算了，我就是因为忘记修改才一直没弄好)
        # 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

        ServerAdmin webmaster@localhost
        DocumentRoot /fangting/www/html(这里修改成自己的目录)

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # 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".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

同目录下修改：
vim /etc/apache2/sites-available/default-ssl.conf
在：DocumentRoot /fangting/www/html(这里修改成自己的目录)

输入：vim /etc/apache2/apache2.conf

<Directory /fang/www/>(修改成自己的目录)
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
