CentOS Linux 升级内核步骤和方法

CentOS Linux 升级内核步骤和方法

1、查看当前系统内核
# uname -r

2.6.32-71.e16.i686

2、下载linux-3.2.14内核包
# tar xvf linux-3.2.14.tar.bz2

# cd linux-3.2.14

3、配置内核并安装
#make mrproper #清除环境变量，即清除配置文件

#cp /boot/config-2.6.32-71.el6.i686 .config

#make menuconfig
#在菜单模式下选择需要编译的内核模块#

#make clean
#确保所有东西均保持最新状态.

#make bzImage
#生成内核文件

#make modules #编译模块

#make modules_install #安装模块

#make install #安装

4、vim /etc/grub.conf，将 default=1 改为 default=0
[root@centos
linux-3.2.14]# cat /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/sda3# initrd /initrd-[generic-]version.img#boot=/dev/sdadefault=0timeout=3splashimage=(hd0,0)/grub/splash.xpm.gzhiddenmenutitle
CentOS Linux (3.2.14-rt24) root (hd0,0) kernel /vmlinuz-3.2.14-rt24 ro root=UUID=ab9d2166-3d58-4c30-84ed-d6d1be1e102e rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM LANG=zh_CN.UTF-8 KEYBOARDTYPE=pc KEYTABLE=us crashkernel=auto rhgb quiet initrd /initramfs-3.2.14-rt24.imgtitle
centos (2.6.32-71.el6.i686) root (hd0,0) kernel /vmlinuz-2.6.32-71.el6.i686 ro root=UUID=ab9d2166-3d58-4c30-84ed-d6d1be1e102e rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM LANG=zh_CN.UTF-8 KEYBOARDTYPE=pc KEYTABLE=us crashkernel=auto rhgb quiet initrd /initramfs-2.6.32-71.el6.i686.img

5、重启系统,并查看内核
# reboot

# uname -r

3.2.14-rt24

6、问题及解决办法

HOSTCC
scripts/basic/fixdepHOSTCC

scripts/kconfig/conf.o

***
Unable to find the ncurses libraries or the*** required header files.*** 'make menuconfig' requires the ncurses libraries.****** Install ncurses (ncurses-devel) and try again.***make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1make: *** [menuconfig] Error
2如果出现上面的错误，记得要安装ncurses-devel，如果你设置了本地源的话，就很简单了。

#
yum install ncurses-devel
