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

# systemctl restart httpd |
2. Confirmation of CGI Script Usage
①Confirmation of CGI availability
The following is displayed and available under “/var/www/cgi-bin/”.
|
1 2 |
# grep -n "^ *ScriptAlias" /etc/httpd/conf/httpd.conf 253: ScriptAlias /cgi-bin/ "/var/www/cgi-bin/" |
②Create test scripts and check operation
|
1 2 3 4 5 |
# vi /var/www/cgi-bin/index.cgi Describe the following #!/usr/bin/python3 print("Content-type: text/html\n") print("CGI Script Test Page") |

Upgrade to Php 8.3
EPEL and Remi repositories are required, so install them if you have not already done so.
|
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 |

# 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.

④Confirmation of PHP operation
Create the following files
|
1 2 3 4 |
# vi /var/www/html/[FQDN]/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.。
|
1 |
# /usr/bin/htdigest -c /etc/httpd/.digestauth "DigestAuth" secretuser |
Confirmation
|
1 2 |
# cat /etc/httpd/.digestauth secretuser:DigestAuth:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx |
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.)
|
1 |
# vi /etc/httpd/conf/httpd.conf |
Add the following at the end
|
1 2 3 4 5 6 7 |
<Directory "/var/www/html/[FQDN]/secret"> AuthType Digest AuthName "DigestAuth" AuthDigestDomain /[FQDN]/secret/ AuthUserFile "/etc/httpd/.digestauth" Require valid-user </Directory> |
Create a directory for Digest authentication
|
1 |
# mkdir /var/www/html/[FQDN]/secret |
Enable Digest authentication and reboot
|
1 |
# systemctl restart httpd.service |
When accessing "http://[FQDN]/secret" with a browser, a screen appears asking for "user name" and "password".
