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

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
