sudo dnf install httpd -y
sudo systemctl enable --now httpd
Check Apache:
sudo systemctl status httpd
Visit http://YOUR_SERVER_IP/ to confirm the default “It works!” page appears
Use virtual hosts to run multiple sites on one server:
sudo vim /etc/httpd/conf.d/example.com.conf
Paste the following content:
<VirtualHost *:80>
ServerName example.com
ServerAlias www.example.com
DocumentRoot /var/www/example.com
ErrorLog /var/log/httpd/example.com-error.log
CustomLog /var/log/httpd/example.com-access.log combined
</VirtualHost>
💡Replace example.com with the fully-qualified domain name (FQDN) of your web server.
Next, run the following commands:
sudo mkdir -p /var/www/example.com
sudo chown -R apache:apache /var/www/example.com
sudo chmod -R 755 /var/www/example.com
echo "<h1>example.com works!</h1>" | sudo tee /var/www/example.com/index.html
sudo systemctl restart httpd
Test by browsing http://example.com

MariaDB is the community-maintained fork of MySQL:
sudo dnf install mariadb-server mariadb -y
sudo systemctl enable --now mariadb
sudo systemctl status mariadb
By default, MariaDB is installed without root password.
sudo mysql_secure_installation

sudo dnf install php php-mysqlnd php-cli php-json php-gd php-xml php-mbstring php-opcache -y
Check:
php -v

Restart Apache to enable PHP:
sudo systemctl restart httpd
PHP-FPM offers better performance under high load. To enable:
sudo dnf install php-fpm -y
sudo systemctl enable --now php-fpm
Edit virtual host:
<FilesMatch \.php$>
SetHandler "proxy:unix:/run/php-fpm/www.sock"
</FilesMatch>
Restart Apache:
sudo systemctl restart httpd
This speeds request handling.
Create a phpinfo() file:
sudo tee /var/www/html/info.php > /dev/null << 'EOF'
<?php phpinfo(); ?>
EOF
sudo systemctl restart httpd
Browse http://YOUR_SERVER_IP/info.php to verify PHP, MariaDB connections, loaded extensions.

Adjust for performance:
| Component | Tuning Changes |
|---|---|
| Apache | Enable mod_deflate, KeepAlive, SSL/TLS configs |
| MariaDB | innodb_buffer_pool_size, log_file_size, etc. phoenixNAP | Global IT Services+1Cloudspinx+1Reddit+4idroot+4LFCS Certification Guide+4 |
| PHP | Set date.timezone, increase upload_max_filesize |
| Security | SELinux audit, fail2ban, mod_security |
Example MariaDB tuning (server.cnf):
[mysqld]
innodb_buffer_pool_size = 256M
innodb_log_file_size = 64M
innodb_flush_log_at_trx_commit = 2
Save and exit the file. Then, restart MariaDB:
sudo systemctl restart mariadb
