Mac下解决mysql ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Go to mysql/bin directory

$ cd /usr/bin

Start a mysql deamon with this option:

$ sudo mysqld_safe --skip-grant-tables

Open another terminal and open a mysql session to execute this:

$ mysql

mysql> use mysql;

see Note1 below for next line.
mysql> UPDATE user SET authentication_string=PASSWORD(‘YOUR_NEW_PASSWORD_HERE‘) WHERE user = ‘root‘;

mysql> exit;

Now kill the mysqld_safe process and restart mysqld normally:

$ sudo service mysqld start

Note1: password is the column name in table mysql.user prior to version 5.7. After which it became authentication_string. Change your update statement accordingly.

如何你们看不懂，给我留言，我教你。
