升级过程：
redhat提供了一个redhat-upgrade-tool的升级工具；
[1]配置软件源
# vim /etc/yum.repos.d/upgrade.repo
[upgrade]
name=upgrade
baseurl=http://dev.centos.org/centos/6/upg/x86_64/
enable=1
gpgcheck=0
[2]安装软件工具
# yum -y install preupgrade-assistant-contents redhat-upgrade-tool preupgrade-assistant
[3]升级前检查潜在问题
# preupg
Preupg tool doesn&＃39;t do the actual upgrade.
Please ensure you have backed up your system and/or data in the event of a failed upgrade
that would require a full re-install of the system from installation media.
Do you want to continue? y/n
