🎯 What You Need

Before we build your private cloud empire, let’s check our supplies! 🛠️ Here’s what you’ll need:

Prerequisites:

• ✅ AlmaLinux 8 or 9 installed and running
• ✅ Root or sudo access (we need admin powers!)
• ✅ At least 4GB RAM (more is better for performance)
• ✅ 20GB free disk space minimum (for OS and Nextcloud)
• ✅ Additional storage for your files
• ✅ Domain name (optional but recommended)
• ✅ About 90 minutes of your time
• ✅ Excitement to own your data! 🎉

📝 Step 1: Installing Required Components

Let’s set up the foundation for your cloud! 🏗️ We need a web server, database, and PHP.

Install LAMP Stack Components:

# Update your system first - always start fresh!
sudo dnf update -y

# Install Apache web server
sudo dnf install httpd -y

# Install MariaDB database server
sudo dnf install mariadb-server mariadb -y

# Install PHP 8 and required extensions for Nextcloud
sudo dnf install php php-curl php-gd php-mbstring php-intl \
    php-mysql php-opcache php-json php-xml php-zip \
    php-process php-bcmath php-gmp -y

# Install additional tools we'll need
sudo dnf install wget unzip policycoreutils-python-utils -y

# Start and enable services
sudo systemctl enable --now httpd
sudo systemctl enable --now mariadb

# Check services are running
sudo systemctl status httpd mariadb
# Both should show Active (running) ✅

Secure MariaDB Installation:

# Run security script
sudo mysql_secure_installation

# Answer the prompts:
# Enter current password: [Press Enter - none yet]
# Switch to unix_socket authentication? [Y/n]: n
# Set root password? [Y/n]: Y
# New password: [Enter strong password like: NextCloud2024!]
# Remove anonymous users? [Y/n]: Y
# Disallow root login remotely? [Y/n]: Y  
# Remove test database? [Y/n]: Y
# Reload privilege tables? [Y/n]: Y

echo "Database secured! 🔐"

🔧 Step 2: Creating Nextcloud Database

Time to create a home for your cloud data! 💾 This is where everything gets stored.

Set Up Database:

# Connect to MariaDB
sudo mysql -u root -p
# Enter the root password you just set

# In the MariaDB prompt, run these commands:
CREATE DATABASE nextcloud CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
CREATE USER 'nextclouduser'@'localhost' IDENTIFIED BY 'SecurePass123!';
GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextclouduser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

echo "Database created successfully! 📊"

Configure PHP for Nextcloud:

# Edit PHP configuration for better performance
sudo nano /etc/php.ini

# Find and modify these values (use Ctrl+W to search):
memory_limit = 512M
upload_max_filesize = 1024M
post_max_size = 1024M
max_execution_time = 300
date.timezone = America/New_York

# Save and exit (Ctrl+X, Y, Enter)

# Create PHP info file to verify
echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/info.php

# Restart Apache to apply PHP changes
sudo systemctl restart httpd

🌟 Step 3: Installing Nextcloud

Now for the main event - installing Nextcloud! ☁️ This is where your cloud comes to life.

Download and Install Nextcloud:

# Download latest Nextcloud (check nextcloud.com for latest version)
cd /tmp
wget https://download.nextcloud.com/server/releases/latest.zip

# Extract Nextcloud
sudo unzip latest.zip -d /var/www/html/

# Set proper ownership
sudo chown -R apache:apache /var/www/html/nextcloud/

# Set proper permissions
sudo find /var/www/html/nextcloud/ -type d -exec chmod 750 {} \;
sudo find /var/www/html/nextcloud/ -type f -exec chmod 640 {} \;

# Create data directory outside web root (more secure!)
sudo mkdir -p /var/nextcloud/data
sudo chown apache:apache /var/nextcloud/data
sudo chmod 750 /var/nextcloud/data

Configure Apache for Nextcloud:

# Create Apache configuration for Nextcloud
sudo tee /etc/httpd/conf.d/nextcloud.conf << 'EOF'
