yum运行时提示被锁住了解决办法

1、当大家用linux的yum时，是不是经常会遇到下面的情况

Loaded plugins: fastestmirror

Existing lock /var/run/yum.pid: another copy is running as pid 3404.

Another app is currently holding the yum lock; waiting for it to exit...

The other application is: yum

State : Sleeping, pid: 3404

没关系，两条语句就可以搞定它。

2、[root@localhost Downloads]# rm -r /var/run/yum.pid
