yum 源可以配到国内的镜像来加速 阿里云，网易，搜狐都可以

这里给个阿里云的说明 http://mirrors.aliyun.com/hel…

先升级 CentOS 到 6.8 Final

yum update

配置 elrepo（官网） 提供的内核源来升级内核

先导入公钥

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

导入源

rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm

然后可以选择安装最新版内核，或者稳定版内核

最新版

yum –enablerepo=elrepo-kernel install -y kernel-ml

稳定版

yum --enablerepo=elrepo-kernel install kernel-lt -y

最后编辑 /etc/grub.conf 启动文件

# 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

        initrd /boot/initramfs-2.6.32-358.el6.x86_64.img

title顺序从上往下 0，1，2
默认新装的应该排在最上面
所以把default值改成0

然后重启
查看版本信息

#cat /etc/redhat-release
CentOS release 6.8 (Final)
# uname -r
3.10.104-1.el6.elrepo.x86_64

搞定
