Requiring a subdirectory to access a webpage service using apache2 and a dynamic DNS

  • 772

I'm trying to disallow the basic 80 HTTP server to be at the root of my dynamic DNS, but instead use a subdirectory.

so instead of blabla.dynamicdns.org it won't be served but at blabla.dynamicdns.org/service it would be.

This configuration attempt did not work. Says document roots are not allowed in Directory tags.

I know how much SE loves its examples, I'm dumping this otherwise vanilla config here anyway.

I literally know nothing and I literally need to be spoon-fed here and it's a pill to Google for this.

<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

    ServerAdmin webmaster@localhost


    # 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
    <Directory /var/www/html/ampache/>
    DocumentRoot /var/www/html/ampache
    DocumentRoot /var/www/html/ampache/public
    </Directory>

    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>

A more correct config, that still does not yield my desired result:

<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

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html/ampache
    DocumentRoot /var/www/html/ampache/public

    # 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>

Sorry for this de facto spam, but my history with SE and lust for "working examples" on topics I don't even know how they work, has forced my hand.

    DocumentRoot always defines the mapping of / (the root directory of your URLs). To define mappings for URL subdirectories, instead use Alias. See Mapping URLs for a general overview.

    Alias /ampache /var/www/html/ampache/public

    (Roughly speaking, DocumentRoot /var/foo is like Alias "/" /var/foo.)

    If you don't want to serve anything at /, map DocumentRoot to an empty directory (possibly even one with restricted permissions) and use Alias to define the individual sub­directories you want.

    It doesn't make sense to have more than one DocumentRoot per vhost, as they all would define mappings for the same / and a URL can only go to one location at a time – only the last definition will be used. Likewise it doesn't make sense to Alias the same path more than once.
