Modify the mysql login password just installed under Linux

1. Use Linux super administrator privileges and
   enter sudo suEnter in the terminal
2. Enter the database
   • Enter mysql -uroot -pEnter at the terminal
   • You are prompted to enter the password, and press Enter directly in the super administrator state to enter the database
3. Enter in the database
   • Modify the mysql root user password:grant all privileges on *.* to root@localhost identified by '你要设置的密码';
   • Refresh the cache:flush privileges;
4. Password reset complete

Note : After
     using this method to modify the default password, there is a chance that it will appear: Use mysql -uroot -p to log in to the database directly with mysql -uroot -p within a few minutes of root privileges (normal accounts do not work), but you will need a password to log in after a few minutes Up.
