					<description><![CDATA[1.Apache2 Install

1.1 httpd Install

# dnf -y install httpd
1.3 Virtual Host Settings

Assign and configure the domain name [FQDN] to the document root [/var/www/html/[FQDN]] directory for virtual host operation
2. Confirmation of CGI Script Usage

①Confirmation of CGI availability
3. PHP installation and configuration

①Install

# dnf -y install php php-mbstring php-pear
4. Digest authentication with Apache2

Since Basic Authentication, a well-known authentication authorization method for http, sends 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 and transmits authentication information, so there is almost no risk of information leakage.]]></description>

					<description><![CDATA[1. Setting up a remote connection via SSH

SSH is a service for connecting remotely to a server and is basically running immediately after the OS is installed, but the default settings are somewhat insecure.
Here we will configure the default settings to increase the security of SSH connections.

1.1 SSH service configuration file changes

The SSH service configuration file is "/etc/ssh/sshd_config".]]></description>

					<description><![CDATA[1. SSL Certificate Acquisition ( Let's Encrypt )

Install the latest open ssl

# dnf install openssl-devel

1.1 advance preparation

1.Package management system Snappy installation
Since the SSL certificate issuing tool "certbot" of Let's Encrypt is recommended to be installed using "snap" after 2021, install Snapd first.(Can also be installed the traditional way with dnf or yum)
2. Converting Apache to https

Install the following

# dnf -y install mod_ssl

2.1 Edit ssl.conf file
3. SSL/TLS (Let's Encrypt) settings on the mail server

3.1 Obtaining a certificate for the mail server

Obtain a certificate for the mail server, but it cannot be obtained in the same way as above, so the following with the "--standalone" option fails.]]></description>
