CentOS6.2版本用yum升級到CentOS6.6

CentOS6.2版本用yum升級到CentOS6.6

因為手上只有6.2版本的CentOS，安裝好後覺著版本太低了，就通過命令列進行升級
查看可用的更新
#yumlist updates
更新升級到centos 6.5
#yumupdate

不幸的是，我在這次的更新過程中，出現了一些錯誤

根據它的提示，執行命令
# yum update --skip-broken
和
# rpm -Va --nofiles --nodigest
都不行，經過網路搜尋找到解決辦法：
1、先卸載qpid-cpp-client
# yum -y remove qpid-cpp-client
2、清除重建緩衝
# yum clean all
# yum makecache
3、重新執行更新動作
# yum update
