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

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
