④operation check
If you access http://[server IP address] and you see the Oracle Apache2 Test Page as shown below, it is OK.

⑤Hide the Oracle Welcome page, create a new index.html file as a Test Page, and check the operation of apache.

Rename the welcome page

# mv /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.conf.org

1	# mv /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.conf.org

Create HTML test page

# vi /var/www/html/index.html
<html>
<body>
<div style="width: 100%; font-size: 40px; font-weight: bold; text-align: center;">
Apache Test Page
</div>
</body>
</html>

# vi /var/www/html/index.html

<html>

<body>

Apache Test Page

</div>

</body>

</html>

If you access http://<server IP address> and the Test Page is displayed as shown below, it is OK.

1	# dnf -y install php php-mbstring php-pear

②Version Check

# php -v
PHP 8.0.20 (cli) (built: Jun  8 2022 00:33:06) ( NTS gcc x86_64 )
Copyright (c) The PHP Group
Zend Engine v4.0.20, Copyright (c) Zend Technologies

# php -v

PHP 8.0.20 (cli) (built: Jun 8 2022 00:33:06) ( NTS gcc x86_64 )

Upgrade to Php 8.1

EPEL and Remi repositories are required, so install them if you have not already done so.

# dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
# dnf -y install https://rpms.remirepo.net/enterprise/remi-release-9.rpm

1 2	# dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm # dnf -y install https://rpms.remirepo.net/enterprise/remi-release-9.rpm

Stop PHP once

# dnf module disable php

1	# dnf module disable php

Installing PHP 8.1

# dnf module install php:remi-8.1

1	# dnf module install php:remi-8.1

php-fpm configuration

# systemctl enable php-fpm
Created symlink /etc/systemd/system/multi-user.target.wants/php-fpm.service → /usr/lib/systemd/system/php-fpm.service.

1 2	# systemctl enable php-fpm Created symlink /etc/systemd/system/multi-user.target.wants/php-fpm.service → /usr/lib/systemd/system/php-fpm.service.

③Restart Apache

After PHP installation, restarting Apache will invoke PHP-FPM (FPM : FastCGI Process Manager) by default, and php-fpm service will be started in conjunction with httpd startup.

# systemctl restart httpd
# systemctl status php-fpm
● php-fpm.service - The PHP FastCGI Process Manager

④Confirmation of PHP operation
Create the following files

# vi /var/www/html/<domain name>/test.php
<?php
 phpinfo();
 ?>

# vi /var/www/html/<domain name>/test.php

<?php

phpinfo();

Access http://<domain name>/test.php in your browser and if you see the following screen, it is OK

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.

4.1 Create password file for Digest authentication

Specify an authenticated area called realm. This realm allows the same directory to be accessed as authenticated.
For this example, the realm is "DigestAuth" and a user and password file named "secretuser" ".digestauth" is created.

# /usr/bin/htdigest -c /etc/httpd/.digestauth "DigestAuth" secretuser

1	# /usr/bin/htdigest -c /etc/httpd/.digestauth "DigestAuth" secretuser

Confirmation

# cat /etc/httpd/.digestauth
secretuser:DigestAuth:64939177c7b7c6eac3687925b27e771d

1 2	# cat /etc/httpd/.digestauth secretuser:DigestAuth:64939177c7b7c6eac3687925b27e771d

As above, secretuser and encrypted password are created

4.2 Edit Apache configuration file

Specify the directory to which Digest authentication will be applied. (In this case, specify the "secret" directory.)

# vi /etc/httpd/conf/httpd.conf

1	# vi /etc/httpd/conf/httpd.conf

Add the following at the end

<Directory "/var/www/html/[FQDN]/secret">
AuthType Digest
AuthName "DigestAuth"
AuthDigestDomain /[FQDN]/secret/
AuthUserFile "/etc/httpd/.digestauth"
Require valid-user
</Directory>
