Why is the ssl certificate not working?

Question

Apache HTTP Server

Hello. I'm trying to install an ssl certificate. I add the following lines to apache2.conf:

<VirtualHost>
DocumentRoot /var/www
ServerName site.ru
SSLEngine On
SSLCertificateFile /etc/ssl/crt/site_ru.crt
SSLCertificateKeyFile /etc/ssl/crt/ssl-cert-snakeoil.key
SSLCertificateChainFile /etc/ssl/crt/site_ru.ca-bundle
SSLSessionCache dbm:/var/cache/httpd/ssl_cache
</VirtualHost>

Restarting apache gives me this error:

Syntax error on line 270 of /etc/apache2/apache2.conf:
<VirtualHost> directive requires additional arguments
Action 'configtest' failed.
The Apache error log may have more information.
 failed!

Where is the mistake?

Answer 1

IP and port not specified:

<VirtualHost *:443>
