Why is there an access denied error in mysql?

Question

MySQL

I installed MySQL on OS X El Captain, during the installation a notification appeared with a password for the root user - I saved this password. I started the mysql server, mysql -u root -p, entered the password, to which I received: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES). Anyone suggest what is the problem? For the second day I can not figure it out.

Answer 1

Try it without a password (without the -p switch), often the default setting for [email protected] will let you.

Answer 2

This means you entered the wrong password.
As an option to google - "Mysql: reset root password", "Reset mysql root password" ... many articles, I used to use it myself
