Every time after installing the system, we have to reinstall some software, and when installing the software, we have to go online to find the installed tutorials, which is more troublesome, so I sorted out the installation method of the mysql-8.0.15-winx64 decompressed version, so that I can install and check it later.

1. First of all, you need to download the unzipped version of MySQL at https://www.mysql.com/downloads/, figure:

two。 Extract the installation package and choose the path according to your preference. The path I chose is D:\ MySQL\, so the full path of MySQL is: d:\ MySQL\ mysql-8.0.15-winx64

3. Configure environment variables

Add system environment variables:

Key name: MYSQL_HOME

The value is: d:\ MySQL\ mysql-8.0.15-winx64

Add:% MYSQL_HOME%\ bin to Path. Note that the ";" symbol between different values in Path cannot be omitted.

4. When the my.ini file is ready, you can first create a new my.txt file, and then change the file suffix to .ini by renaming it. The my-default.ini file may exist after decompression in the previous version, but not in version 5.7.21, so you need to create the file manually. The contents of the file are as follows:

[mysqld] port = 3306basedir=D:/MySQL/mysql-8.0.15-winx64datadir=D:/MySQL/mysql-8.0.15-winx64/data max_connections=200character-set-server=utf8default-storage-engine=INNODBsql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_ tables [MySQL] default-character-set=utf8

Note that the installation path of MySQL is in the red box, and use "/" instead of "\" between folders, otherwise errors may occur in the following operations
