Modify the path and copy it directly into your .ini file Well, the
first step 
is to configure your environment variables. I won't say much about the decompression path. Just put it in the
cmd shortcut key to find cmd.exe, right-click to select it , and run dos as administrator
Use the command to enter the bin directory of your mysql, such as my directory F:\ServiceFile\mysql\mysql-5.7.21-winx64\bin. The effect is as shown in Figure
1 above. Execute the command: mysqld –initialize-insecure, initialize mysql
2 and then later Execute the command, mysqld
3 If the above two commands are successful, then open cmd as an administrator, enter the bin directory of mysql, and execute the command mysql -uroot
4 This will also enter the mysql environment, then modify the user password and execute Command: ALTER USER 'root'@'localhost' IDENTIFIED BY 'your password';
5 Execute the quit command, then execute mysqladmin -uroot -p shutdown to shut down the mysql process
6 If it fails, exit and log in to mysql -u your name -p you password; then perform step 5
7 mysqld –install (install MySQL service), if nothing else, your mysql environment is installed. After
success , the shortcut key win+r
and then find your mysql and start it.
