因为手上只有6.2版本的CentOS，安装好后觉着版本太低了，就通过命令行进行升级
查看可用的更新
# yum list updates
更新升级到centos 6.5
# yum update
不幸的是，我在这次的更新过程中，出现了一些错误
Error: Package: matahari-host-0.4.4-11.el6.i686 (@anaconda-CentOS-201112130233.i386/6.2)
Requires: libqpidclient.so.5
Removing: qpid-cpp-client-0.12-6.el6.i686 (@anaconda-CentOS-201112130233.i386/6.2)

根据它的提示，执行命令
# yum update --skip-broken
和
# rpm -Va --nofiles --nodigest
都不行，经过网络搜索找到解决办法：
1、先卸载qpid-cpp-client
# yum -y remove qpid-cpp-client
2、清除重建缓存
# yum clean all
# yum makecache
3、重新执行更新动作
# yum update
