Apache how to properly set up a virtual host?

Question

Apache HTTP Server

Hello The
following question:
A number of virtual hosts are now configured on Apache for second-level domains:
test.example.com:80
test2.example.com:80
test3.example.com:80
Now there is a task to make one more virtual host, for example demo.example. com but to which all other second-level domains that are not registered as separate virtual hosts will refer. I tried to do it through ServerAlias ​​*.example.com , but then other hosts stop working. Those. opening test.example.com opens demo.example.com.
Can you tell me if it's realistic? And if it's real, how?

Answer 1

Order matters

<VirtualHost *:80>
    DocumentRoot /var/www/test1
    ServerName test1.site.com
</VirtualHost>
<VirtualHost *:80>
    DocumentRoot /var/www/test2
    ServerName test2.site.com
</VirtualHost>
<VirtualHost *:80>
    DocumentRoot /var/www/test3
    ServerName test3.site.com
</VirtualHost>
<VirtualHost *:80>
    DocumentRoot /var/www/tests
    ServerAlias *.site.com
</VirtualHost>
