MySQL 8.0 installation-free version configuration method
For different operating systems, MySQL provides corresponding versions. Under the Windows operating system, the installation package of the MySQL database is divided into two types: GUI installation and installation-free installation. The installation methods of these two installation packages are different, and the configuration methods are also different. The GUI installation package has a complete installation wizard, which is very convenient for installation and configuration. The installation-free installation package can be directly decompressed and used, but it is inconvenient to configure. The article mainly introduces the configuration method of mysql 8.0.26 installation-free version for you in detail
