Description

What are the bare-minimum hardware specs for MySQL?

Allocate at least 1 vCPU, 1 GB RAM, and 5 GB of free SSD storage to spin up a non-production MySQL 8 instance. Anything smaller will fail during binary installation or crash under basic query load.

Which operating systems are officially supported?

MySQL 8 runs on 64-bit Linux (Ubuntu 20.04+, RHEL 8+), Windows 10 Pro/Server 2016+, and macOS 12+.Make sure glibc 2.17+ on Linux, the Visual C++ 2019 runtime on Windows, and Xcode command-line tools on macOS are present.

How do I verify 64-bit binaries?

Run file $(which mysqld) on Unix or check the installer name on Windows (mysql-8.x.x-winx64.msi). A 32-bit binary limits memory use to 4 GB and is no longer shipped for MySQL 8.

Is 1 GB RAM really enough?

1 GB is only safe for personal experiments.For an ecommerce workload with the example tables, allocate 4 GB so innodb_buffer_pool_size can cache hot rows (≈70 % of RAM).

How do I see current memory settings?

Connect and run SHOW VARIABLES LIKE 'innodb_buffer_pool_size';. Compare the value to total RAM with free -h (Linux) or Task Manager (Windows).

What disk speed is required?

Use SSDs that sustain 2000+ IOPS.HDDs bottleneck Orders and OrderItems range scans, causing 10× slower checkout queries.

How do I benchmark disk quickly?

On Linux run sudo hdparm -Tt /dev/nvme0n1. Look for cached reads >5000 MB/s and buffered reads >2000 MB/s.

When should I scale CPU cores?

Add cores when concurrent writes deadlock. Monitor Threads_running; if it stays > (vCPU×2) during peak, double cores.

What network settings matter for remote clients?

Ensure a 1 Gbps NIC and configure wait_timeout=28800 to keep API connections alive.Latency impacts SELECT COUNT(*) FROM Orders calls on dashboards.

Best practices for production sizing

4 vCPU, 8 GB RAM, 100 GB SSD for startups
Set innodb_flush_log_at_trx_commit=1 for durability
Enable binary logging for point-in-time recovery
Store data and logs on separate volumes

What’s next after meeting minimums?

Automate daily backups, configure monitoring (Prometheus, Percona PMM), and test failover with MySQL InnoDB Cluster.

Why How to minimum system requirements for MySQL in PostgreSQL is important

How to minimum system requirements for MySQL in PostgreSQL Example Usage


-- Stress-test minimal hardware by running an aggregate on ecommerce data
SELECT c.name,
       COUNT(o.id)   AS total_orders,
       SUM(o.total_amount) AS lifetime_value
FROM   Customers c
JOIN   Orders o ON o.customer_id = c.id
GROUP  BY c.id
ORDER  BY lifetime_value DESC
LIMIT  10;

How to minimum system requirements for MySQL in PostgreSQL Syntax


# Check current buffer pool size
SHOW VARIABLES LIKE 'innodb_buffer_pool_size';

# Install on Ubuntu
sudo apt update && sudo apt install mysql-server

# Initialize data directory (custom path)
mysqld --initialize --datadir=/data/mysql --user=mysql

# Start server with explicit memory limits
mysqld --innodb-buffer-pool-size=512M --max-connections=150

Common Mistakes

Under-allocating RAM—setting innodb_buffer_pool_size higher than available memory causes swapping and query stalls. Fix by reserving at least 70 % RAM for MySQL, leaving 30 % for OS.
Using spinning disks in production—high write latency slows transactions and replication. Migrate data to SSD volumes and enable write-combining caches.
