MariaDB® on AlmaLinux 9

Reliable MariaDB® server on AlmaLinux 9, delivering scalable, secure, and open-source database solutions optimized for Azure cloud.

This offer provides a robust and scalable MariaDB® database on AlmaLinux 9, optimized for cloud-native and traditional database workloads on Azure. AlmaLinux is a community-driven, enterprise-class Linux distribution fully compatible with RHEL®, ensuring stability, security, and long-term support.

The VM comes pre-installed with hardened MariaDB®, enabling quick deployment of an enterprise-ready database solution suitable for development, testing, or production environments.

Security hardening includes:

• Anonymous users and test databases removed
• Remote root login disabled
• Root password unset by default – must be securely configured after deployment
• Strict password policy: minimum 8 characters, includes digit, upper/lower case, and special symbol

Configuration enhancements:

• DNS lookups disabled – faster and more secure client connections
• Symbolic links disabled to prevent filesystem exploits
• LOAD DATA LOCAL INFILE disabled to block unauthorized file access
• Listener bound to localhost – no external access unless configured
• Slow and error logs redirected to structured log files

Performance and storage tuning:

• Higher max connections and open table cache for scalable concurrency
• Slow query log enabled with 2-second threshold
• UTF8MB4 character set and Unicode-aware collation – full language and emoji support
• InnoDB: Direct I/O, 512MB buffer pool, one-file-per-table, sync log flush, 10-day log retention
• Aria engine: expanded buffer for efficient temporary tables

Backup tool included: A dedicated MariaDB® backup utility is pre-installed, requiring minimal configuration. Optimized for fast change capture, low-latency transfers, and consistent snapshot integrity.

Password customization: To adjust password rules, edit /var/lib/mysql/init_custom.sql with root access.

Logs are stored in /var/log/mariadb/
