CentOS Linux 升級內核步驟和方法 linux
一、查看當前系統內核 vim
# uname -r二、下載linux-3.2.14內核包 centos
# tar xvf linux-3.2.14.tar.bz2三、配置內核並安裝 ui
#make mrproper #清除環境變量,即清除配置文件四、vim /etc/grub.conf,將 default=1 改成 default=0 this
[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/sda default=0 timeout=3 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title 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.img title 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五、重啓系統,並查看內核 spa
# reboot
