MySQL is a relational database management system originally developed by MySQL AB in Sweden and now owned by Oracle Corporation. It is designed to store data in separate tables rather than in a single large repository, which enhances speed and flexibility. The SQL language used by MySQL is the most widely adopted standardized language for interacting with databases. MySQL offers a dual licensing model, consisting of a free community version and a paid commercial version. Due to its compact size, high performance, low total cost of ownership, and open-source nature, it is commonly chosen for small and medium-sized website development projects. Thanks to the strong performance of its community edition, MySQL pairs well with PHP and Apache to create a stable development environment.
In this guide, I will walk you through the process of installing MySQL on a Windows 64-bit system. Since the official MSI installer only provides a 32-bit version, I opted for the ZIP archive instead.
Here’s how I installed MySQL:
1. First, I visited the official MySQL download page at http://dev.mysql.com/downloads/mysql/ and downloaded the Windows (x86, 64-bit) ZIP Archive.
2. After downloading, I extracted the files to my desired installation directory. I chose D:\MySql\mysql-5.7.12-winx64\. Once unzipped, the folder should contain several directories and files.
3. To proceed with configuration, I made sure that file extensions were visible. On Windows 7, I went to "Computer" > "Organize" > "Folder and Search Options" > "View" tab, and unchecked the option "Hide extensions for known file types."
4. Next, I created a new `my.ini` configuration file in the same directory as `my-default.ini`. This file will override the default settings. I opened the `my.ini` file and added the following configuration:
```
[mysql]
default-character-set=utf8
[mysqld]
port=3306
basedir=D:\MySql\mysql-5.7.12-winx64
datadir=D:\MySql\mysql-5.7.12-winx64\data
max_connections=200
character-set-server=utf8
default-storage-engine=INNODB
```
5. After saving the `my.ini` file, I created an empty `data` folder in the specified path.
6. Then, I opened Command Prompt as an administrator and navigated to the `bin` directory of the MySQL installation. I ran the command `mysqld --initialize-insecure --user=mysql` to initialize the database without a password.
7. Next, I installed the MySQL service using the command `mysqld install`.
8. After the service was successfully installed, I started the MySQL service.
9. Finally, I configured the system's environment variables by adding the `bin` directory path to the `PATH` variable, ensuring that I could access MySQL from any location.
10. To test the installation, I opened Command Prompt again and entered `mysql -uroot -p`. Since no password was set during initialization, I simply pressed Enter to log in.
This concludes the installation and basic usage of MySQL. I hope this guide helps you get started with MySQL. If you have any questions or suggestions, feel free to share them—I'm always looking to improve and learn alongside the community.
Piezoelectric Buzzer For External Drive
The piezoelectric transducers (for External
Drive) produce exceptional sound output and efficiency all while meeting each
customers unique performance requirements. Piezo transducers are constructed
without magnets, instead they create sound mechanically via the piezoelectric effect.
Our piezo transducers are not equipped with a built in drive circuit. This
provides our customers with the flexibility of designing their own circuitry to
meet their specific needs. The advantage of using an external drive circuit is
that the piezo transducers can output sounds at multiple frequencies. Full
bridge circuits ramp up SPL for more peak-to-peak voltage, making our piezo
transducers a high output solution.
