Centos 6.X升级内核

摘要: Centos 6.X升级内核

Install Kernel 3.10 on CentOS 6.X

CentOS 6.X ships with kernel 2.6 and it’s a quite old for now(CentOS 7 already comes with 3.10), but compile a kernel on CentOS is a mess and it’s not recommended. But fear no more, guys from Elrepo took care of that for us and made a package, lets see how we can install it.

Enable ELRepo Project repository

1.rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
2.rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm

Install the kernel

1.yum --enablerepo=elrepo-kernel install kernel-lt

Configure grub

You also need edit

/etc/grub.conf

to change the kernel order, change default from 1 to 0, must looks like the below:
1.default=0

2.timeout=5

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

4.hiddenmenu

5.title CentOS (3.10.55-1.el6.elrepo.x86_64)

6.root (hd0,0)

7.kernel /vmlinuz-3.10.55-1.el6.elrepo.x86_64 ro root=/dev/mapper/VolGroup-lv_root rd_NO_LUKS.UTF-8 rd_NO_MD rd_LVM_LV=VolGroup/lv_swap SYSFONT=latarcyrheb-sun16 crashkernel=auto rd_LVM_LV=VolGroup/lv_root rd_NO_DM KEYBOARDTYPE=pc KEYTABLE=br-abnt2 rhgb quiet ...

8....

Reboot and profit!

1.reboot

Now you have a fresh(not so much) kernel on CentOS.(http://elrepo.org)
