本文主要是介绍CentOS6.4 升级内核3.4.56步骤和方法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
当前系统为 CentOS1、查看当前系统内核
# uname -r 2 2.6.32-358.el6.i686
2、下载linux-3.4.56内核包
# cd ~ # wget -c https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.4.56.tar.xz # tar -Jxvf linux-3.4.56.tar.xz # mv linux-3.4.56 /usr/src/linux-3.4.56 # cd linux-3.4.56
3、配置内核并安装
# make mrproper #清除环境变量，即清除配置文件 # 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、编辑
# 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/mapper/VolGroup-lv_root # initrd /initrd-[generic-]version.img #boot=/dev/sda default=1 timeout=3 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (3.4.56)root (hd0,0) kernel /vmlinuz-3.4.56 ro root=UUID=2c06f495-2f8c-4930-8968-9c612d32edc1 rd_NO_LUKS KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD crashkernel=auto LANG=zh_CN.UTF-8 rd_NO_LVM rd_NO_DM rhgb quiet initrd /initramfs-3.4.56.img title CentOS (2.6.32-358.14.1.el6.i686) root (hd0,0) kernel /vmlinuz-2.6.32-358.14.1.el6.i686 ro root=UUID=2c06f495-2f8c-4930-8968-9c612d32edc1 rd_NO_LUKS KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD crashkernel=auto LANG=zh_CN.UTF-8 rd_NO_LVM rd_NO_DM rhgb quiet initrd /initramfs-2.6.32-358.14.1.el6.i686.img title CentOS (2.6.32-358.el6.i686) root (hd0,0) kernel /vmlinuz-2.6.32-358.el6.i686 ro root=UUID=2c06f495-2f8c-4930-8968-9c612d32edc1 rd_NO_LUKS KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD crashkernel=auto LANG=zh_CN.UTF-8 rd_NO_LVM rd_NO_DM rhgb quiet initrd /initramfs-2.6.32-358.el6.i686.img
5、重启系统,并查看内核
# reboot # uname -r 3.4.56
