经过长时间学习CentOS gcc，你可能会遇到CentOS gcc安装问题，这里将介绍CentOS gcc安装问题的解决方法。更新CentOS安装gcc遇到的一个问题。

起因是在一个trixbox上安装CentOS gcc第一步，更新系统的软件包到最新yum -y update漫长的等待过后，reboot，然后再次运行了yum -y update 确认再没有可更新的模块了。

接下来，安装CentOS gcc yum -y install gcc没想到

CentOS gcc出错啦，貌似是缺少kernel-headers,So, I try "yum install kernel-headers":
[trixbox1.localdomain src]# yum install kernel-headers

CentOS gcc后来看到有人说到默认的CentOS-Base.repo是不包含下载kernel的，果然注释掉里边的exclude=kernel* 再次运行yum -y update.我靠，又开始下载一个kernel包。罪魁祸首在这里啊！再次执行yum install CentOS gcc 这下应该没有问题了吧！In case anyone's wondering, I don't make a habit of talking to myself.
