How It Affects Your App

4. Check the MySQL user privileges to see if any users have been granted too many privileges:
$ mysql -u root -p -e "SELECT User, Host, Password FROM mysql.user;"
5. Check the MySQL database tables for any corrupt data:
$ mysqlcheck -u root -p --all-databases
6. Restart the MySQL service to apply any changes made:
