我正在尝试在Droplet上打开端口，以添加第二个站点，我想通过ip：port（在我的情况下为8000端口）访问该站点。我有这个配置文件：

main.conf

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html/VetPartnersPrintPortal/public

        <Directory /var/www/html/VetPartnersPrintPortal/public>
            Options Indexes FollowSymLinks
            AllowOverride All
            Require all granted
        </Directory>

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

        <IfModule mod_dir.c>
            DirectoryIndex index.php index.pl index.cgi index.html index.xhtml index.htm
        </IfModule>

</VirtualHost>

slider.conf

<VirtualHost *:8000>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html/slider/

        <Directory /var/www/html/slider/>
            Options Indexes FollowSymLinks
            AllowOverride All
            Require all granted
        </Directory>

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

        <IfModule mod_dir.c>
            DirectoryIndex index.php index.pl index.cgi index.html index.xhtml index.htm
        </IfModule>

</VirtualHost>

ufw状态提供以下信息：
