Answer 1

1.Go to Services tab on your windows and check whether MySQL running or not.
2.Adding MySQL to path,
Open "Edit system variables".
Click on "Environment variables"
Click on "Path" and click on "Edit"
Click on "New" and paste your MySQL path.
(C:\Program Files\MySQL\MySQL Shell 8.0\bin)
3.From doing above scenarios you don't need to call your MySQL path every time you want to run MySQL using command line.
4.Now open command line and type this (Here -u is username and -p is password),
mysql -u root -p (After typing hit enter).
It will ask for your password, if you have no password just hit enter
