First, extract it to a directory you want to install, I unzipped is D: \ Program Files (taking into account the long-extracting file names from so I named)
Second, add an environment variable
My Computer -> Properties -> Advanced -> Environment Variables
Select the PATH, add it back: your mysql installation file following the bin folder
(如: D:\Program Files\mysql-5.7\bin )
(Be careful not to remove the other stuff)
Third, create a new my.ini file
Fourth, edit my.ini file
[mysqld]
basedir=D:\Program Files\mysql-5.7\
datadir=D:\Program Files\mysql-5.7\data\
port=3306
skip-grant-tables
represents mysql installation path #basedir
#datadir represent mysql data file storage path
#port expressed mysql port
# Skip-grant-tables omit the password
Five, the CMD in the administrator mode starts, and the path is switched to the bin directory mysql, then enter
mysqld –install
Six, enter mysqld --initialize-insecure --user = mysql; initialization data file
Seven, enter net start mysql start mysql service
Eight, then start again and then use the command mysql -u root -p enter mysql mysql management interface (password can be empty)
Nine, change the root password into the interface
update mysql.user set authentication_string=password('123456789') where user='root' and Host = 'localhost';
Ten, the last input flush privileges to refresh authority
XI, modify my.ini file to delete the last sentence of skip-grant-tables
XII restart mysql normal use
