Description

Why install MySQL on Windows?

Local MySQL lets you prototype features, run integration tests, and analyze data without touching production. Windows users can leverage native tools like Workbench while keeping data secure on their own laptops.

What are the prerequisites?

Ensure you have administrative rights, Windows 10/11, and at least 2 GB free disk space.Disable any old MySQL or MariaDB services to avoid port 3306 conflicts.

Which installer should I choose?

Use the "MySQL Installer for Windows" (full ≈ 400 MB, web ≈ 2 MB). The installer bundles Server, Workbench, Shell, and Connector/ODBC.

How do I run the installer step-by-step?

1. Download mysql-installer-community-x.x.xx.x.msi. 2. Launch as Administrator. 3. Select "Developer Default" for all tools. 4. Accept license, then let the installer fetch packages.

Configuration wizard steps

• Type: Standalone. • Port: 3306 (keep default).• Auth: "Use Strong Password Encryption".
• Root password: choose >= 12 chars. • Accounts: optionally add ecom_admin user.

How do I initialize and start the service manually?

"C:\Program Files\MySQL\MySQL Server 8.0\bin\mysqld" --initialize --console generates the data directory.
mysqld --install MySQL80 registers Windows service.
net start MySQL80 starts the server.

How do I verify the installation?

Open PowerShell and run mysql -u root -p. After entering your password, check with SHOW DATABASES;.You should see mysql, performance_schema, and others.

How do I create an e-commerce schema quickly?

Run:

CREATE DATABASE ecommerce;
USE ecommerce;
Then create tables like Customers, Orders, Products, and OrderItems.

Best practices after setup?

• Store root credentials in a password manager.
• Create least-privileged users for apps.
• Enable automated Windows services start-up.
• Backup data\ folder or use mysqldump.

Common mistakes and fixes

Port already in use: Stop conflicting services or change MySQL port.
Forgotten root password: Start mysqld with --skip-grant-tables, reset password, then restart normally.

Need to uninstall?

Stop the service (net stop MySQL80), remove it (sc delete MySQL80), uninstall via "Apps & Features", then delete C:\ProgramData\MySQL\.
