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 以后，登录之后，无论运行任何命令，老是提示这个

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好了，以上除了红色的本身修改为新密码外，其余原样输入便可
