mac mysql error You must reset your password using ALTER USER statement before executing this statement.

安装完mysql 之后，登陆以后，不管运行任何命令，总是提示这个

step 1:

SET PASSWORD = PASSWORD('your new password');

step 2:

ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;

step 3:

flush privileges;

完成以上三步退出再登，使用新设置的密码就行了，以上除了红色的自己修改成新密码外，其他原样输入即可
