Another app is currently holding the yum lock

问题解决：Another app is currently holding the yum lock; waiting for it to exit...

运行yum update的时候如果用Ctrl + C强制退出，再次运行yum的时候有如下错误：

Existing lock /var/run/yum.pid: another copy is running as pid 3053.
Another app is currently holding the yum lock; waiting for it to exit...
The other application is: PackageKit
Memory : 37 M RSS ( 82 MB VSZ)
Started: Sun Jan 24 16:11:53 2010 - 14:44 ago
State : Sleeping, pid: 3053


解决办法：




1、rm -f /var/run/yum.pid
2、/sbin/service yum-updatesd restart








默认情况下kill向该进程发送的信号是SIGTERM，该信号会非常友好地（gracefully）等待进程的自动退出，所以一般不会达到立即杀死进程的目的，如果要立即杀死进程可以加上-9或者是-SIGKILL信号。例如：kill -SIGKILL 1234
