• MariaDB Official Repository: Latest stable versions with faster updates
• Source Compilation: Maximum customization but requires more time and expertise
• Docker Container: Isolated environment, perfect for development and testing

Method 1: Installing from Ubuntu Default Repository

This is the quickest method and works well for most development and production scenarios. Ubuntu 24 ships with MariaDB 10.11, which is a long-term support release.

# Update package index
sudo apt update

# Install MariaDB server and client
sudo apt install mariadb-server mariadb-client -y

# Check installation status
systemctl status mariadb

# Enable MariaDB to start on boot
sudo systemctl enable mariadb

After installation, verify the version:

mariadb --version

Method 2: Installing from MariaDB Official Repository

For access to the latest features and faster security updates, using the official MariaDB repository is recommended. This method gives you access to MariaDB 11.x series.

# Install software-properties-common for repository management
sudo apt install software-properties-common -y

# Import MariaDB signing key
wget -O- https://mariadb.org/mariadb_release_signing_key.asc | sudo gpg --dearmor -o /usr/share/keyrings/mariadb-keyring.gpg

# Add MariaDB repository
echo "deb [signed-by=/usr/share/keyrings/mariadb-keyring.gpg] https://mirror.mariadb.org/repo/11.4/ubuntu noble main" | sudo tee /etc/apt/sources.list.d/mariadb.list

# Update package index
sudo apt update

# Install MariaDB
sudo apt install mariadb-server mariadb-client -y

Initial Security Configuration

Immediately after installation, run the security script to remove default accounts and set up proper authentication:

sudo mariadb-secure-installation

The script will prompt you for several security settings:

• Root password: Set a strong password for the root user
• Remove anonymous users: Always choose ‘Y’ for production systems
• Disallow root login remotely: Choose ‘Y’ unless you specifically need remote root access
• Remove test database: Choose ‘Y’ to clean up the test database
• Reload privilege tables: Choose ‘Y’ to apply changes immediately

Essential Configuration

MariaDB’s main configuration file is located at /etc/mysql/mariadb.conf.d/50-server.cnf. Here are some important settings to consider:

# Edit the configuration file
sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf

# Key settings to modify:
[mysqld]
# Bind to specific IP (change from 127.0.0.1 for remote access)
bind-address = 127.0.0.1

# InnoDB buffer pool size (set to 70-80% of available RAM)
innodb_buffer_pool_size = 1G

# Query cache (useful for read-heavy applications)
query_cache_type = 1
query_cache_size = 256M

# Maximum connections
max_connections = 500

# Enable slow query log for performance monitoring
slow_query_log = 1
slow_query_log_file = /var/log/mysql/slow-query.log
long_query_time = 2

After making configuration changes, restart MariaDB:

sudo systemctl restart mariadb

Creating Databases and Users

Here’s how to create a database and user for your applications:

# Connect to MariaDB as root
sudo mariadb -u root -p

# Create a new database
CREATE DATABASE myapp_production;

# Create a new user with proper privileges
CREATE USER 'myapp_user'@'localhost' IDENTIFIED BY 'secure_password_here';

# Grant privileges to the user
GRANT ALL PRIVILEGES ON myapp_production.* TO 'myapp_user'@'localhost';

# Apply changes
FLUSH PRIVILEGES;

# Exit MariaDB
EXIT;

Common Installation Issues and Troubleshooting

Here are the most frequent problems you might encounter and their solutions:

Issue 1: MariaDB Service Won’t Start

# Check detailed error logs
sudo journalctl -u mariadb.service

# Check MariaDB error log
sudo tail -f /var/log/mysql/error.log

# Common fix: Reset file permissions
sudo chown -R mysql:mysql /var/lib/mysql
sudo chmod -R 755 /var/lib/mysql

Issue 2: Can’t Connect After Installation

Ubuntu 24’s MariaDB uses unix_socket authentication by default for the root user. This means you need to use sudo:

# This works
sudo mariadb -u root

# This might not work without additional configuration
mariadb -u root -p

To enable password authentication for root:

sudo mariadb -u root
ALTER USER 'root'@'localhost' IDENTIFIED BY 'your_password';
FLUSH PRIVILEGES;
EXIT;

Issue 3: Repository Key Errors

If you encounter GPG key errors when using the official repository:

# Remove old keys and re-add
sudo apt-key del 0xF1656F24C74CD1D8
wget -O- https://mariadb.org/mariadb_release_signing_key.asc | sudo gpg --dearmor -o /usr/share/keyrings/mariadb-keyring.gpg

Performance Optimization for Production

For production environments, consider these performance tuning parameters:

# Add to [mysqld] section in configuration file
[mysqld]
# InnoDB settings
innodb_buffer_pool_size = 4G  # Adjust based on available RAM
innodb_log_file_size = 512M
innodb_flush_log_at_trx_commit = 2
innodb_file_per_table = 1

# MyISAM settings (if using MyISAM tables)
key_buffer_size = 256M
myisam_sort_buffer_size = 64M

# Connection settings
max_connections = 200
connect_timeout = 60
wait_timeout = 120

# Query cache settings
query_cache_size = 256M
query_cache_limit = 2M

Real-World Use Cases and Applications

MariaDB on Ubuntu 24 excels in various scenarios:

Security Best Practices

Implement these security measures for production deployments:

# Create a dedicated user for applications (never use root)
CREATE USER 'webapp'@'localhost' IDENTIFIED BY 'complex_password';
GRANT SELECT, INSERT, UPDATE, DELETE ON webapp_db.* TO 'webapp'@'localhost';

# Enable SSL connections
[mysqld]
ssl-ca = /etc/mysql/ssl/ca-cert.pem
ssl-cert = /etc/mysql/ssl/server-cert.pem
ssl-key = /etc/mysql/ssl/server-key.pem

# Restrict network access
bind-address = 127.0.0.1

# Regular security updates
sudo apt update && sudo apt upgrade mariadb-server

Backup and Maintenance

Set up automated backups to prevent data loss:

# Create backup script
#!/bin/bash
BACKUP_DIR="/var/backups/mariadb"
DATE=$(date +%Y%m%d_%H%M%S)

mkdir -p $BACKUP_DIR
mariadb-dump --all-databases --single-transaction --routines --triggers > $BACKUP_DIR/full_backup_$DATE.sql

# Keep only last 7 days of backups
find $BACKUP_DIR -name "*.sql" -mtime +7 -delete

Add this script to your crontab for daily execution:

# Edit crontab
sudo crontab -e

# Add this line for daily backup at 2 AM
0 2 * * * /path/to/backup_script.sh

Integration with Popular Frameworks

MariaDB integrates seamlessly with modern development frameworks:

# Django settings.py
DATABASES = {
    'default': {
