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?
Code: Select all
# openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/pki/tls/private/localhost.key -out /etc/ssl/certs/localhost.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 "192.168.1.2" IP address, what is the content of "/etc/hostname" and "/etc/hosts" files? Is below configuration OK?
Code: Select all
# cat /etc/hostname
#localhost.localdomain
example-test.net
Code: Select all
# cat /etc/hosts
#127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
#::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.2 example-test.net example-test
Thank you.
