1.1 Apache2 install
2. Use of CGI Scripts

①CGI availability check
3. PHP installation and configuration
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[OracleLinux8.10 Install

Oracle Linux provides a 100% application binary compatible alternative to Red Hat Enterprise Linux and CentOS Linux for both hybrid and multi-cloud environments.
Since 2006, Oracle Linux has been completely free to download and use. Source code, binaries and updates are provided free of charge. It is freely redistributable. Free for use in production environments.

We will proceed with the latest updated Oracle Linux 8.10 (released August 29, 2024) with Vo.8.

Oracle Linux 8.10 installation image (OracleLinux-R8-U10-x86_64-dvd.iso ) can be downloaded from the following site

					<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.
2.Firewall (Firewalld) settings

In Oracle, the firewall is firewalld configured by default and enabled during OS installation.

To briefly explain "firewalld," when setting communication control policies, communication permission/blocking rules are applied to predefined zones, and these zones are then assigned to each NIC (network adapter).]]></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>
