yum运行时提示被锁住了怎么办

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 8404.
Another app is currently holding the yum lock; waiting for it to exit...

2、没关系，两条语句就可以搞定它。

[root@centos5 ~]# rm -r /var/run/yum.pid
rm：是否删除 一般文件 “/var/run/yum.pid”? y
[root@centos5 ~]# /sbin/service yum-updatesd restart
停止 yum-updatesd：                                        [确定]
启动 yum-updatesd：                                        [确定]
