2020-09-19T03:55:28.803727Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.
2020-09-19T03:55:29.181810Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.
2020-09-19T03:55:30.170195Z 6 [Note] [MY-010454] [Server] A temporary password is generated for [email protected]: YJl8j9Sfea:4

The last line is the initial password , Remember , When entering the database for the first time, use , Change the password at that time
Then run the following statement to install and start MySQL

D:\mysql-8.0.21-winx64\bin>mysqld -install
Service successfully installed.

D:\mysql-8.0.21-winx64\bin>net start mysql
MySQL  The service is starting  .
MySQL  Service started successfully .

Show MySQL Service started successfully . Even if it's successful
The next time you start, just run after entering the administrator mode net start mysql That's all right. , If you stop, just net stop mysql Just ok！
PS： If you fail halfway , You must remove the entire service before you can reinstall .
function sc delete mysql || mysql -remove, It is effective to reopen the terminal after deletion , If after opening sc query mysql Discovery still exists （type and state Wait for no reason 0）, however sc delete mysql || mysql -remove But there is no such service , You can restart the computer .

Start using MySQL

Make sure that after starting the service , stay bin Under the table of contents mysql -u root -p, Enter the initial password , Login successful . Change the initial password , Otherwise, we can't do mysql operation , and root Password must be strong . Run in the database

# Change it to lowercase and see if it makes the meaning clearer ：alter user 'root'@'localhost' identified by 'xxxxx'
ALTER USER 'root'@'localhost' IDENTIFIED BY 'xxxxx';
# If you want to use Navicat We need to change the encryption method 
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'xxxxx';
# Refresh the permissions 
FLUSH PRIVILEGES;

The password you changed is xxxxx, And this password is a strong password （ Case letters , Numbers , punctuation ）. Then you can use the database .
If you want to use Python perhaps Java Linked database , There are special tutorials , I won't go over it here . You can also use the graphical interface to view the database later , Baidu can be directly , There are also many tutorials .
