方法一:
# ps aux | grep yum
# kill -9 pid
方法二:
可以通过执行rm -rf /var/run/yum.pid 来强行解除锁定,然后你的yum就可以运行了
解释:
[[email protected] wangcheng]# yum list
Existing lock /var/run/yum.pid: another copy is running as pid 3807.
Another app is currently holding the yum lock; waiting for it to exit...
字面意思是说另外一个程序给yum加了锁,要等到该程序退出以后才可以进行。
