在yum的ELRepo源中,有 m ain l ine(3.13.1)、 l ong- t erm(3.10.28)这2个内核版本,考虑到long-term更稳定,会长期更新,所以选择这个版本。
1、导入public key
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
2、安装ELRepo到CentOS-6.5中
rpm -ivh http://www.elrepo.org/elrepo-release-6-5.el6.elrepo.noarch.rpm
3、安装 kernel-lt(lt=long-term)
yum --enablerepo=elrepo-kernel install kernel-lt -y
或者安装kernel-ml(ml=mainline)
yum --enablerepo=elrepo-kernel install kernel-ml -y
4、编辑grub.conf文件,修改Grub引导顺序
vim /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 do not have a /boot partition. This means that # all kernel and initrd paths are relative to /, eg. # root (hd0,0) # kernel /boot/vmlinuz-version ro root=/dev/sda1 # initrd /boot/initrd-[generic-]version.img #boot=/dev/sda default=0 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (3.10.28-1.el6.elrepo.x86_64) root (hd0,0) kernel /boot/vmlinuz-3.10.28-1.el6.elrepo.x86_64 ro root=UUID=0a05411f-16f2-4d69-beb0-2db4cefd3613 rd_NO_LUKS KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD crashkernel=auto LANG=en_US.UTF-8 rd_NO_LVM rd_NO_DM rhgb quiet initrd /boot/initramfs-3.10.28-1.el6.elrepo.x86_64.img title CentOS (2.6.32-431.3.1.el6.x86_64) root (hd0,0) kernel /boot/vmlinuz-2.6.32-431.3.1.el6.x86_64 ro root=UUID=0a05411f-16f2-4d69-beb0-2db4cefd3613 rd_NO_LUKS KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD crashkernel=auto LANG=en_US.UTF-8 r d_NO_LVM rd_NO_DM rhgb quiet initrd /boot/initramfs-2.6.32-431.3.1.el6.x86_64.img title CentOS (2.6.32-431.el6.x86_64) root (hd0,0) kernel /boot/vmlinuz-2.6.32-431.el6.x86_64 ro root=UUID=0a05411f-16f2-4d69-beb0-2db4cefd3613 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 /boot/initramfs-2.6.32-431.el6.x86_64.img
确认刚安装好的内核在哪个位置,然后设置default值(从0开始),一般新安装的内核在第一个位置,所以设置default=0。
5、重启,查看内核版本号
[root@dev ~]# uname -r 3.10.28-1.el6.elrepo.x86_64
