Apache2 InstallAllow http:80 port and https:443 port in UFW first.3 Apache2 : Using Perl ScriptsEnable CGI to make Perl scripts available①Perl Install4 Apache2 : Using PHP Scripts①PHP Install5 Apache2 : Virtual Host Settings①Copy the default configuration file (file name is arbitrary, in this case vhost-yourdomain.conf as an example) and configure the virtual host6. Digest authentication with Apache2Since 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.

On the way, enter the password for the key.
