1.1 Apache2 install

①httpd install

# dnf -y install httpd
1.3 Virtual Host Settings

Assign and configure the domain name [rocky.korodes.com] to the document root [/var/www/html/rocky.korodes.com] directory for virtual host operation
2. Use of CGI Scripts

①CGI availability check
3. PHP installation and configuration
1.PHP8 Install
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 informa]]></description>

					<description><![CDATA[SSH connection with authentication using public key cryptography

 Creation of public and private key pairs

Create a public/private key pair for a user connecting to the Linux server using OpenSSH.
Use ssh-keygen to create key pairs.
Creation of public/private key pairs is performed with remote login user privileges。
If you do not specify the destination and file name, id_ed25519 and id_ed25519.pub will be created in /home/(user name)/.ssh/. On the way, enter the password for the key.]]></description>

					<description><![CDATA[1.Disabling SELinux

First, disable selinux. selinux is a feature that improves auditing and security in Linux, but when enabled, it places considerable restrictions on the behavior of services and on what can be configured. Therefore, it is basically disabled in many cases.
SELinux operating modes
Enforcing : SELinux functionality is enabled and access control is enabled
Permissive : SElinux will warn, but no access restrictions will be placed
disabled : Both SElinux function and access control are disabled
2.System Modernization

Package updates are performed as soon as possible immediately after OS installation.
However, when a dnf update is performed, a kernel update is also performed at the same time.
A kernel update may require rebooting the system or stopping services, or worse, a kernel panic may occur and the system may not boot. It is wiser to exclude the kernel from the update.
The kernel can be excluded from updates by running dnf -y update with "--exclude=kernel*" after it.]]></description>

					<description><![CDATA[1.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 Edit SSH service configuration file

Modify the configuration file to change the SSH service settings.
The SSH service configuration file is "/etc/ssh/sshd_config".
2.Firewall (firewalld) settings

The firewall is set to firewalld as default and is enabled during OS installation.
4.NTP Server

Build an NTP server to synchronize the server time with Japan Standard Time]]></description>

					<description><![CDATA[1.Obtain an SSL certificate ( Let's Encrypt )

Install the latest open ssl

# dnf install openssl-devel
1.1 advance preparation

1.Package management system Snappy installed
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 just in case

# dnf -y install mod_ssl
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>
