How to create a virtual host in Apache2?

Question

Apache HTTP Server

There is: Apache2, domain and website (example.ru).
Goal: host another site (site.example.ru).
2 configuration files are created in site-available:
1. For example.ru:

<VirtualHost *:80>
        ServerName example.ru
  ServerAlias example.ru *.exapmle.ru
  ServerAdmin [email protected]
        DocumentRoot /home/artem/themezv
  ErrorLog ${APACHE_LOG_DIR}/error.log
  CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

2. For site.example.ru:

<VirtualHost *:80>
  ServerName site.example.ru
  ServerAlias site.example.ru *.site.example.ru
  ServerAdmin [email protected]
  DocumentRoot /home/artem/liza
  ErrorLog ${APACHE_LOG_DIR}/error.log
  CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

But example.ru opens, and site.example.ru gives a dns lookup error.
I ask for help in setting up. And because I did it myself, but I have no experience, is everything correct in the configurations above?
