Verifying MySQL Installation
After installation, it's crucial to verify that MySQL is running correctly:
- Open your command line interface (Command Prompt, Terminal)
- Type the following command to log into MySQL as root:
mysql -u root -p
Configuring MySQL for Optimal Use
Once installed, you might want to perform some basic configuration tasks:
