可能是系统自动升级正在运行，yum在锁定状态中。
已经有一个yum进程在运行了，使用kill干掉它：
# kill -s 9 14997 # ps aux|grep yum root 6744 0.0 0.0 103260 900 pts/1 S+ 14:59 0:00 grep yum root 14997 0.0 0.0 0 0 ? Z Sep19 0:01 [yumBackend.py] <defunct>1234
很遗憾，kill对付不了它，那怎么办呢？
可以通过强制关掉yum进程：
解决方法：
rm -rf /var/run/yum.pid 来强行解除锁定，然后你的yum就可以运行了
