Then enter cd D:\software\mysql-8.0.32-winx64\bin to enter the MySQL bin directory (Note that you need to enter your own MySQL bin directory）
cd D:\software\mysql-8.0.32-winx64\bin
Then execute the following command in the bin directory: mysqld --initialize --console
mysqld --initialize --console
Note : root@localhost: -qbm2FYOI9oU (the one marked in the picture below, everyone is different) is the initial password (does not include the first space). You need to copy and save this (do not type it by hand to avoid errors), and you will use it later (-qbm2FYOI9oU )
