linux 内核启动顺序修改_hjzhang0428_新浪博客

可修改启动配置文件，更改系统默认加载的内核！

查看有两个grub.conf，分别是/etc/grub.conf，还有/boot/grub/grub.conf

两个文件应该是一样的

/etc/grub.conf: symbolic link to `../boot/grub/grub.conf’

#vi /etc/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-version.img

#boot=/dev/sda

default=1

timeout=5

splashimage=(hd0,0)/grub/splash.xpm.gz

hiddenmenu

title Red Hat Enterprise Linux Server (2.6.18-53.el5PAE)

root (hd0,0)

kernel /vmlinuz-2.6.18-53.el5PAE ro

root=LABEL=/1 3 rhgb quiet

initrd /initrd-2.6.18-53.el5PAE.img

title Red Hat Enterprise Linux Server-xen (2.6.18-53.el5xen)

root (hd0,0)

kernel /xen.gz-2.6.18-53.el5

module /vmlinuz-2.6.18-53.el5xen ro

root=LABEL=/1 3 rhgb quiet

module /initrd-2.6.18-53.el5xen.img

title Red Hat Enterprise Linux Server-base (2.6.18-53.el5)

root (hd0,0)

kernel /vmlinuz-2.6.18-53.el5 ro root=LABEL=/1 3

rhgb quiet

initrd /initrd-2.6.18-53.el5.img

将其中的default =1改为你需要的。（注：默认顺序是从0开始）
