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
|
1 |
# mv /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.conf.org |
Create HTML test page
|
1 2 3 4 5 6 7 8 |
# 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> |
If you access http://[server IP] and the Test Page is displayed as shown below, it is OK.
1.3 Virtual Host Settings
Assign and configure the domain name [oracle.korodes.com] to the document root [/var/www/html/oracle.korodes.com] directory for virtual host operation
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
# vi /etc/httpd/conf.d/vhost.conf Virtual Host Domain Settings <VirtualHost *:80> DocumentRoot /var/www/html/oracle.korodes.com ServerName oracle.korodes.com ServerAdmin <Email Address> ErrorLog logs/oracle.korodes.com-error_log CustomLog logs/oracle.korodes.com-access_log combined </VirtualHost> <Directory "/var/www/html/oracle.korodes.com"> Options FollowSymLinks AllowOverride All </Directory> |
Creating a Document Directory
|
1 |
# mkdir /var/www/html/oracle.korodes.com |
Restart Apache
|
1 |
# systemctl restart httpd |
2. Confirmation of CGI Script Usage
①Confirmation of CGI availability
|
1 2 3 |
# grep -n "^ *ScriptAlias" /etc/httpd/conf/httpd.conf 252: ScriptAlias /cgi-bin/ "/var/www/cgi-bin/" The above is displayed and available under "/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") |
|
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
①Install
|
1 |
# dnf -y install php php-mbstring php-pear |
②Version Check
|

# php -v PHP 8.0.27 (cli) (built: Jan 3 2023 16:17:26) ( NTS gcc x86_64 ) Copyright (c) The PHP Group Zend Engine v4.0.27, Copyright (c) Zend Technologies with Zend OPcache v8.0.27, Copyright (c), by Zend Technologies |
Upgrade to Php 8.2
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 |
Stop PHP once
|
1 |
# dnf module disable php |
Installing PHP 8.2
|
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. |
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 Loaded: loaded (/usr/lib/systemd/system/php-fpm.service; enabled; preset: > Active: active (running) since Sun 2023-08-13 19:38:26 JST; 28s ago Main PID: 7649 (php-fpm) Status: "Processes active: 0, idle: 5, Requests: 0, slow: 0, Traffic: 0req> Tasks: 6 (limit: 9321) Memory: 14.5M CPU: 38ms CGroup: /system.slice/php-fpm.service tq7649 "php-fpm: master process (/etc/php-fpm.conf)" tq7651 "php-fpm: pool www" tq7652 "php-fpm: pool www" tq7653 "php-fpm: pool www" tq7654 "php-fpm: pool www" mq7655 "php-fpm: pool www" Aug 13 19:38:26 Lepard systemd[1]: Starting The PHP FastCGI Process Manager... Aug 13 19:38:26 Lepard systemd[1]: Started The PHP FastCGI Process Manager. |
④Confirmation of PHP operation
Create the following files
|
1 2 3 4 |
# 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.
|
1 |
# /usr/bin/htdigest -c /etc/httpd/.digestauth "DigestAuth" secretuser |
Confirmation
|
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.)
|
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".
