What are the absolute hardware minimums for MariaDB?

MariaDB can start on a single-core 64-bit CPU, 1 GB RAM, and 512 MB of free SSD/HDD space. This footprint supports a dev or test instance with light concurrency and small datasets.

Which operating systems meet the base requirement?

MariaDB 10.6+ is certified on 64-bit Linux (Ubuntu 20.04+, RHEL/CentOS 8+, Debian 11+), Windows Server 2016+, and macOS 11+. A 64-bit kernel is non-negotiable; 32-bit systems are unsupported.

How much memory should I provision per connection?

Allocate 1–2 MB per idle connection and 4–8 MB per active connection. For 50 active sessions, 1 GB RAM covers the buffer pool, sort buffers, and per-thread overhead.

Does storage speed affect the minimum spec?

Yes. SSDs drastically cut fsync latency, so even the minimum disk size (512 MB) should be an SSD for write-intensive workloads. Aim for 100 MB/s sequential write throughput.

How do I verify the server fits in memory?

Run SHOW GLOBAL VARIABLES and compare innodb_buffer_pool_size to free -m output. Keep buffer_pool ≤70% of physical RAM on a minimal box to avoid swapping.

Checklist for a micro-instance

• 1 vCPU @2 GHz
• 1 GB RAM
• 512 MB free SSD
• 64-bit Linux kernel
• Swap disabled or limited to 512 MB

How to size for small ecommerce apps?

An ecommerce prototype with Customers, Orders, Products, and OrderItems tables (~1 GB data) runs smoothly on 2 vCPU, 4 GB RAM, and 20 GB SSD. Increase innodb_buffer_pool_size to 2 GB.

Best practices for staying within minimum specs?

Enable slow_query_log, set performance_schema=OFF, and schedule mysqlcheck DDoptimize weekly. These reduce overhead and keep the instance within resource limits.

Why How to Check Minimum System Requirements for MariaDB is important

How to Check Minimum System Requirements for MariaDB Example Usage


-- Confirm the micro-instance can handle basic ecommerce traffic
EXPLAIN SELECT c.name, COUNT(o.id) AS orders
FROM Customers c
JOIN Orders o ON o.customer_id = c.id
GROUP BY c.id
ORDER BY orders DESC
LIMIT 10;

How to Check Minimum System Requirements for MariaDB Syntax


-- Check MariaDB version and architecture
SELECT VERSION();

-- Review memory-intensive settings
SHOW GLOBAL VARIABLES LIKE 'innodb_buffer_pool_size';

-- Estimate current data size in an ecommerce schema
SELECT table_schema,
       ROUND(SUM(data_length+index_length)/1024/1024,2) AS MB
FROM information_schema.tables
WHERE table_schema IN ('Customers','Orders','Products','OrderItems')
GROUP BY table_schema;

Common Mistakes

Frequently Asked Questions (FAQs)

Can MariaDB run on a Raspberry Pi?

Yes. A Pi 4 with 2 GB RAM and a fast SD-card or USB SSD meets the minimum spec for dev workloads.

Is swap space required?

Swap is optional but recommended at 0.5–1× RAM for crash safety. On low-memory systems, disable swappiness to avoid performance hits.

How much disk does the system database use?

The mysql system schema consumes roughly 80 MB after installation, so allocate at least 512 MB to leave headroom for logs and temp files.
