					<description><![CDATA[Apache2 installation and virtual host configuration

1.Apache2 Install
Digest authentication in Apache2

Since Basic Authentication, a well-known authentication authentication method for http, transmits authentication information in plain text, there is a risk of ID and password leakage if the packet is intercepted.
On the other hand, Digest Authentication encrypts the authentication information and sends it in encrypted form, so there is almost no risk of information leakage.

①httpd Install
3.Virtual Host Settings

Assign and configure the [FQDN] to be operated on the virtual host in the document root [/var/www/html/FQDN] directory
PHP installation and configuration

1.PHP Install
