I have some questions about Apache configuration and I'm thankful if anyone help me.

1- In Apache configuration, both of "ServerName" and "ServerAlias" must be defined? Which one must have "www" prefix ?

2- If "/etc/pki/tls/private/localhost.key" and

"/etc/ssl/certs/localhost.crt" files deleted then how can I regenerate them? Is below command OK?

# openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/pki/tls/private/localhost.key -out /etc/ssl/certs/localhost.crt

The "localhost" is the name of my host? If my hostname is "example-test" then these files name must be "example-test.key" and "example-test.crt" ?

3- By default, Linux use "localhost.localdomain" if I installed Apache and my web site is up too then can I change "localhost.localdomain" ? Can it make any problem?

4- For a web site with the name "example-test.net" and "" IP address, what is the content of "/etc/hostname" and "/etc/hosts" files? Is below configuration OK?

# cat /etc/hostname


# cat /etc/hosts
#   localhost localhost.localdomain localhost4 localhost4.localdomain4
#::1         localhost localhost.localdomain localhost6 localhost6.localdomain6   example-test.net   example-test

It is a great help if anyone answer my questions by number.

Thank you.
