• Initial configuration and account setup
• Tools for managing your MySQL server

💽 MySQL Installation Methods

You can install MySQL in multiple ways depending on your OS and requirements.

Windows Installation (Using MySQL Installer)

1. Download MySQL Installer from dev.mysql.com.
2. Run the .msi file and choose Full or Developer Default setup.
3. Select products:
   • MySQL Server
   • MySQL Workbench
   • MySQL Shell
   • Connector/ODBC, C++, Python, etc.
4. Proceed with installation and configuration:
   • Set root password
   • Choose Standalone MySQL Server
   • Configure port (default: 3306)
   • Enable MySQL as a Windows Service

MySQL Workbench will be available after setup for GUI-based administration.

macOS Installation (Using DMG or Homebrew)

Option 1: DMG Installer

1. Download DMG from MySQL website.
2. Run installer and follow GUI instructions.
3. Set root password and install the Startup Item to run MySQL on boot.

Option 2: Homebrew (Recommended for developers)

brew update
brew install mysql
brew services start mysql

Test the installation:

mysql -u root

Linux Installation (APT/YUM Package Manager)

Ubuntu / Debian (APT):

sudo apt update
sudo apt install mysql-server
sudo systemctl start mysql
sudo mysql_secure_installation

RHEL / CentOS / Fedora (YUM/DNF):

sudo yum install mysql-server
sudo systemctl start mysqld
sudo mysql_secure_installation

Use systemctl enable mysql to start on boot
Run sudo mysql to enter MySQL shell as root

Initial Configuration & Secure Setup

Run the security script:

sudo mysql_secure_installation

It allows you to:

• Set or update root password
• Remove anonymous users
• Disallow root login remotely
• Remove test databases
• Reload privilege tables

Creating First Database and User

After installation, you can log in and start working:

mysql -u root -p

-- Create a database
CREATE DATABASE my_app;

-- Create a user and grant privileges
CREATE USER 'admin'@'localhost' IDENTIFIED BY 'StrongPass!123';
GRANT ALL PRIVILEGES ON my_app.* TO 'admin'@'localhost';
FLUSH PRIVILEGES;

Tools Included with Installation

Installing MySQL in the Cloud

You can also use fully managed MySQL on platforms like:

• Amazon RDS for MySQL
• Google Cloud SQL for MySQL
• Azure Database for MySQL
• Oracle Cloud MySQL HeatWave

No manual installation needed—just configure instance type, region, root credentials, and access policies.

Summary – Recap & Next Steps

Installing MySQL is the first step in building powerful, data-driven applications. Whether you’re a beginner or deploying at scale, choosing the right installation method and securing your environment is crucial.

Key Takeaways

• Install MySQL via Installer (Windows), DMG/Homebrew (macOS), or APT/YUM (Linux)
