First put all the folders mysql5.7 in the C drive for easy writing path (modify mysql5.7 \ my file content basedir = C: \ mysql5.7 datadir = C: \ mysql5.7 \ data
to the path you installed yourself The files are the same I set)
Add skip-grant-tables to indicate that no password is required to enter the database!
…
