Virtual hosts
Serve two sites from one Apache process.
A virtual host is a block of directives that apply to one hostname or IP. Name-based vhosts share an address and split on the Host header.
<VirtualHost *:80>
ServerName lab.example
DocumentRoot /var/www/lab
ErrorLog ${APACHE_LOG_DIR}/lab-error.log
CustomLog ${APACHE_LOG_DIR}/lab-access.log combined
</VirtualHost>On Debian, drop that file in sites-available, run a2ensite, and reload. Point DNS or your hosts file at the box before you wonder why you still see the default page.
