②If Firewalld is enabled, HTTP service permission is required; HTTP uses [80/TCP]

# firewall-cmd --add-service=http --permanent
# firewall-cmd --add-service=https --permanent
# firewall-cmd --reload

# firewall-cmd --add-service=http --permanent

# firewall-cmd --add-service=https --permanent

# firewall-cmd --reload

⑥operation check
If you access http://[server IP address] and you see the Oracle Apache2 Test Page as shown below, it is OK.

⑦Hide 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.

1.3 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

# 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>

# vi /etc/httpd/conf.d/vhost.conf

Virtual Host Domain Settings

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>

Options FollowSymLinks

AllowOverride All

</Directory>

Creating a Document Directory

# mkdir /var/www/html/oracle.korodes.com

1	# mkdir /var/www/html/oracle.korodes.com

Restart Apache

# systemctl restart httpd

1	# systemctl restart httpd

2. Confirmation of CGI Script Usage

①Confirmation of CGI availability

# 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/".

# 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

# vi /var/www/cgi-bin/index.cgi
#!/usr/bin/python3
print("Content-type: text/html\n")
print("CGI Script Test Page")

# vi /var/www/cgi-bin/index.cgi

#!/usr/bin/python3

print("Content-type: text/html\n")

print("CGI Script Test Page")

# chmod 755 /var/www/cgi-bin/index.cgi
# curl localhost/cgi-bin/index.cgi
CGI Script Test Page

# chmod 755 /var/www/cgi-bin/index.cgi

# curl localhost/cgi-bin/index.cgi

CGI Script Test Page

3. PHP installation and configuration

1.PHP install

①Install

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

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

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
