redhat默认自带的[yum][]源需要注册，才能更新，报错：   
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager   
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

Trying other mirror.   
可替换为[centos][]对应的源。

CentOS6-Base-163.repo 替换后的文件内容（）

# CentOS-Base.repo
    #
    # The mirror system uses the connecting IP address of the client and the
    # update status of each mirror to pick mirrors that are updated to and
    # geographically close to the client.  You should use this for CentOS updates
    # unless you are manually picking other mirrors.
    #
    # If the mirrorlist= does not work for you, as a fall back you can try the 
    # remarked out baseurl= line instead.

更换yum源，将原有源删除或备份到别的目下下：

cd /etc/yum.repos.d/ 
    wget http://mirrors.163.com/.help/CentOS6-Base-163.repo 
    vi CentOS6-Base-163.repo 编辑文件，把文件里面的$releasever全部替换为版本号：6（注意，不是6.5！）最后保存！ 
    替换命令： %s/$releasever/6/g

清除原有缓存，重建缓存：   
\#yum clean all   
\#yum makecache

更新系统（以上步骤完成后可先尝试yum是否能用， 不能用在使用该命令。 该命令执行很长时间）  
\#yum update
