Subdomains not working

Question

Apache HTTP Server

There is an example.com domain connected via a2ensite:

<VirtualHost *:80>
        ServerName example.com
        ServerAdmin [email protected]

        DocumentRoot /home/inetbug/www/example.com
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /home/inetbug/www/example.com/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>
</VirtualHost>

I wanted to make it so that when I go to subdomain.example.com Apache opens another directory:

<VirtualHost *:80>
        ServerName subdomain.example.com
        ServerAdmin [email protected]

        DocumentRoot /home/inetbug/www/subdomain
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /home/inetbug/www/subdomain/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>
</VirtualHost>

Again, I added this configuration via a2ensite, but it does not work - the address is not found by the browser. What obvious thing did I forget to add? Maybe problems with the domain itself?

Answer 1

DNS returns IP for subdomain? It is checked by a banal subdomain ping.
Quite an obvious thing - they forgot to reload Apache.

Answer 2

Somewhat little information.
What's in ns? Well, did Apache reboot? ;)

Answer 3

You need to add ServerAlias ​​subdomain.example.com to your configuration
