④operation check
f you access http://[server IP address] and see the AlmaLinux Test Page as shown below, it is OK.
⑤Hide the Welcome page, create a new index.html file as a Test Page, and check apache operation
Rename the welcome page
|
1 |
# mv /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.conf.org |
|
1 2 3 4 5 6 7 8 9 |

Creating a Document Directory
|
1 |
# mkdir /var/www/html/alma.korodes.com |
Apache Restart
|
1 |
# systemctl restart httpd |
Create test pages and check operation
|
1 2 3 4 5 6 7 8 |
# vi /var/www/html/alma.korodes.com/index.html <html> <body> <div style="width: 100%; font-size: 40px; font-weight: bold; text-align: center;"> Virtual Host Test Page </div> </body> </html> |
Access."http://rocky.korodes.com/index.html"
If the following screen appears, it is normal.
2. Use of CGI Scripts
①CGI availability check
|
1 2 3 |
# grep -n "^ *ScriptAlias" /etc/httpd/conf/httpd.conf 250: ScriptAlias /cgi-bin/ "/var/www/cgi-bin/" The above is displayed and available under "/var/www/cgi-bin/". |
②The above is displayed and available under "/var/www/cgi-bin/".
|
1 2 3 4 5 |
# vi /var/www/cgi-bin/index.cgi #!/usr/libexec/platform-python print("Content-type: text/html\n") print("CGI Script Test Page") |
|
1 2 3 |
# chmod 755 /var/www/cgi-bin/index.cgi # curl localhost/cgi-bin/index.cgi CGI Script Test Page |
3. PHP installation and configuration
3.1.PHP Install
①Install
|
1 |
# dnf -y install php |
②Version Check
|
1 2 3 4 |
# php -v PHP 7.2.24 (cli) (built: Oct 22 2019 08:28:36) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies |
If you are on Php 7.2, upgrade to Php 8.2.
If you are installing Php8.2, you will need the Remi repository, so install it if you have not already done so.
|
1 |
# dnf -y install https://rpms.remirepo.net/enterprise/remi-release-8.rpm |
Stop PHP once
|
1 |
# dnf module disable php |
PHP 8.2 Install
|
1 |
# dnf module install php:remi-8.2 |
php-fpm configuration
|
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. |
|
1 2 3 4 5 6 |
# systemctl start php-fpm # php -v PHP 8.2.12 (cli) (built: Oct 24 2023 19:22:16) (NTS gcc x86_64) Copyright (c) The PHP Group Zend Engine v4.2.12, Copyright (c) Zend Technologies with Zend OPcache v8.2.12, Copyright (c), by Zend Technologies |
If the version is updated to 8.2, it is OK.
③Apache Restart
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.

Oct 31 09:59:32 Lepard systemd[1]: Started The PHP FastCGI Process Manager. |
④Confirmation of PHP operation
Create the following files
|
1 2 |
# vi /var/www/html/[FQDN]/test.php <?php phpinfo(); ?> |
If you access http://[FQDN]/test.php in your browser and 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 |
Create index.html under /var/www/html/[FQDN]/secret
|
1 2 3 4 5 6 7 8 9 |
# vi /var/www/html/[FQDN]/secret/index.html <html> <body> <div style="width: 100%; font-size: 40px; font-weight: bold; text-align: center;"> Digest Secret Test Page </div> </body> </html> |
When accessing http://[FQDN]/secret with a browser, a screen appears asking for "user name" and "password"
Success if the following screen appears
