Install Kernel 3.10 on CentOS 6.5
CentOS 6.5 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.
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
1.yum --enablerepo=elrepo-kernel install kernel-lt
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....
1.reboot
Now you have a fresh(not so much) kernel on CentOS.(http://elrepo.org)
