为什么这么做,筒子们都懂得,直接上操作步骤:
leekwen@leekwen:~# grub-mkpasswd-pbkdf2 Enter password: <<<这里输入你的grub密码 Reenter password: <<<这里输入你的grub密码 Your PBKDF2 is grub.pbkdf2.sha512.10000.BC4D0A450E86EE447561FC822C832xxxxxxxxxxxxx45572D3B4E40500CE leekwen@leekwen:~# cp /etc/grub.d/00_header /etc/grub.d/00_header.bak leekwen@leekwen:~# vi /etc/grub.d/00_header leekwen@leekwen:~# tail -n 6 /etc/grub.d/00_header ### Add those line to set GRUB2 password cat <<EOF set superusers="leekwen" password_pbkdf2 leekwen grub.pbkdf2.sha512.10000.BC4D0A450E86EE447561FC822C832xxxxxxxxxxxxx45572D3B4E40500CE EOF ### Add end leekwen@leekwen:/etc/grub.d# update-grub <<运行此命令才可以生效 Generating grub.cfg ... Found linux image: /boot/vmlinuz-3.11.0-15-generic Found initrd image: /boot/initrd.img-3.11.0-15-generic Found memtest86+ image: /memtest86+.bin done 这样重启后,在启动项时,按e后,就会让你输入: username: password: 只有用户名(比如我刚刚设置的用户名为:leekwen)及密码正确后(刚刚用grub-mkpasswd-pbkdf2生成的密码),才可以进入启动项的编辑菜单,启动项这一步倒是安全了,记住,修改00_header后一定要运行“update-grub”命令,这样才能生效!!! |
