CentOs yum命令时提示“Another app is currently holding the yum lock

执行yum命令时，提示

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

exit…”

等错误字样。这是因为yum被锁定无法使用导致的。

错误信息参考：

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

exit… The other application is: yum Memory : 40 M RSS ( 50 MB VSZ)

解决方案：

rm -rf /var/run/yum.pid

SSH执行以上命令，删除yum.pid强行解除锁定即可。
