过程记录(Centos6 and Newer)

我装的是Centos6.5

$ yum update -y
$ uname -a
Linux li1192-83.members.linode.com 4.1.5-x86_64-linode61 #7 SMP Mon Aug 24 13:46:31 EDT 2015 x86_64 x86_64 x86_64 GNU/Linux
$ yum install kernel.x86_64 -y #对于64位

Create a file named /boot/grub/menu.lst with the following contents. Adjust the title, kernel, and initrd lines to reflect the actual file names found in the /boot/ directory.

$ cd /boot && ls
$ mkdir /boot/grub
$ cd /boot/grub
$ touch menu.lst
$ vi menu.lst

根据个人实际情况，添加如下内容

timeout 1 #开机倒计时
title CentOS (2.6.32-573.3.1.el6.x86_64)
root (hd0)
kernel /boot/vmlinuz-2.6.32-573.3.1.el6.x86_64 root=/dev/xvda
initrd /boot/initramfs-2.6.32-573.3.1.el6.x86_64.img

• In the Linode Manager, edit your Linode’s configuration profile to use either pv-grub-x86_32 or pv-grub-x86_64 as the Kernel, depending on the version of CentOS you have deployed (32-bit or 64-bit).
• Make sure the root device is specified as xvda.
• Save your changes by clicking Save Profile at the bottom of the page.
• Reboot your Linode from the Dashboard tab.
• Once your Linode has rebooted, log in via SSH and issue the following command:

uname -a
