grub加密有明文加密碼和密文加密

????命令：grub-md5-crypt

??????? [root@lnmp01 rc.d]# grub-md5-crypt
????Password: ????????????????
????Retype password:
????$1$p9Y9a$Id5hMpbsHLNZFs0gPbRRI.

密碼加密后密文：$1$p9Y9a$Id5hMpbsHLNZFs0gPbRRI.

配置/boot/grub/grub.conf

????[root@lnmp01 rc.d]# vim /boot/grub/grub.conf

????# grub.conf generated by anaconda
????#
????# Note that you do not have to rerun grub after making changes to this file
????# NOTICE:? You have a /boot partition.? This means that
????#????????? all kernel and initrd paths are relative to /boot/, eg.
????#????????? root (hd0,0)
????#????????? kernel /vmlinuz-version ro root=/dev/sda2
????#????????? initrd /initrd-[generic-]version.img
????#boot=/dev/sda
????default=0
????timeout=5
????splashp_w_picpath=(hd0,0)/grub/splash.xpm.gz
????hiddenmenu

????#在此處對grub加密

??? password --md5 $1$p9Y9a$Id5hMpbsHLNZFs0gPbRRI.

????title CentOS 6 (2.6.32-504.el6.x86_64)
??????? root (hd0,0)
如果password --md5 $1$p9Y9a$Id5hMpbsHLNZFs0gPbRRI.替換成：password? 123456

則表示使用明文加密。
