To install LAMP (Linux, Apache, MySQL/MariaDB, PHP) on CentOS 9 Stream, follow these steps:
Step 1: Update System Packages
Ensure your system is up to date:
sudo dnf update -y
Step 2: Install Apache (httpd)
sudo dnf install httpd -y
Start and enable Apache:
sudo systemctl start httpd
sudo systemctl enable httpd
Verify Apache is running:
sudo systemctl status httpd
Allow HTTP and HTTPS traffic in the firewall:
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload
Step 3: Install MariaDB (MySQL alternative)
sudo dnf install mariadb-server -y
Start and enable MariaDB:
sudo systemctl start mariadb
sudo systemctl enable mariadb
Secure your MariaDB installation:
sudo mysql_secure_installation
Follow the prompts to set a root password and secure the database.
Step 4: Install PHP
sudo dnf install php php-mysqlnd php-cli php-common php-opcache php-gd php-curl php-mbstring -y
Restart Apache to apply changes:
sudo systemctl restart httpd
Step 5: Test PHP
Create a test PHP file:
echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/info.php
Open your web browser and visit:
http://your-server-ip/info.php
If PHP info is displayed, PHP is working correctly.
Step 6: Adjust SELinux (If Necessary)
If your website faces permission issues, run:
sudo setsebool -P httpd_can_network_connect on
Step 7: Enable Services on Boot
sudo systemctl enable httpd
sudo systemctl enable mariadb
Step 8: Remove the Test PHP File (for security)
sudo rm -f /var/www/html/info.php
Your LAMP stack is now ready on CentOS 9 Stream!
