最近的linux 版本的编译总是出错，请教了下大牛说是linux 内核版本太高了。

`uname -a`  
`Linux 2.6.32-642.11.1.el6.x86_64 #1 SMP Fri Nov 18 19:25:05 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux`

而我们需要的是2.6.32-573.

这里需要查看/etc/grub.conf

    # Note that you do not have to rerun grub after making changes to this file
    # NOTICE: You have a /boot partition. This means that
    # all kernel and initrd paths are relative to /boot/, eg.

    # kernel /vmlinuz-version ro root=/dev/sda3
    # initrd /initrd-[generic-]version.img
    #boot=/dev/sda
    default=2
    timeout=5
    splashimage=(hd0,0)/grub/splash.xpm.gz
    hiddenmenu
    title CentOS (2.6.32-696.1.1.el6.x86_64)
        root (hd0,0)

default=2 这个就是制定选择那个版本的内核。  
title默认的是0开始，选择对应的版本后，reboot。

再次uname -a 可以参看已经完成了内核版本的选择。

通常我们可能安装一些软件会使内核升级，这种方法可以方便的回退。
