I am facing a strange problem. I recently set up a fresh CentOS7 minimal install with an apache 2.4 server to replace an older server (CentOS5 / Apache 2.2) in production. However, when I copied the Vhosts config from the old server to the new, I noted that when I did "httpd -S", the output did not show the aliases, BUT the server IS answering all the expected aliases...
I tried to test both IP based and name based Vhosts to no avail.
I made exactly the same steps on another server I need to replace, and the behavior between the old server and the new one.
I also compared the apache confs between the 2 new servers (httpd.conf, ssl.conf and the vhosts conf), they are identical.
*:443 is a NameVirtualHost default server vhost.company.com port 443 namevhost vhost.company.com alias alias1.company.com alias alias2.company.com alias alias3.company.com
*:443 server vhost.company.com
What on earth could cause this difference between two Apache servers?
Thanks for your expertise!
