CentOS 6.7 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.
\nBut fear no more, guys from Elrepo took care of that for us and made a package, let’s see how we can install it.<\/p>\n
Enable ELRepo Project repository<\/p>\n
rpm –import https:\/\/www.elrepo.org\/RPM-GPG-KEY-elrepo.org
\nrpm -Uvh http:\/\/www.elrepo.org\/elrepo-release-6-6.el6.elrepo.noarch.rpm<\/p>\n
Install the kernel<\/p>\n
yum –enablerepo=elrepo-kernel install kernel-lt<\/p>\n
Configure grub<\/p>\n
You also need edit \/etc\/grub.conf to change the kernel order, change default from 1 to 0, must looks like the below:<\/p>\n
default=0
\ntimeout=5
\nsplashimage=(hd0,0)\/grub\/splash.xpm.gz
\nhiddenmenu
\ntitle CentOS (3.10.55-1.el6.elrepo.x86_64)
\nroot (hd0,0)
\nkernel \/vmlinuz-3.10.55-1.el6.elrepo.x86_64 ro root=\/dev\/mapper\/VolGroup-lv_root rd_NO_LUKS LANG=en_US.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\u00a0 KEYBOARDTYPE=pc KEYTABLE=br-abnt2 rhgb quiet<\/p>\n
