yum 出现Existing lock /var/run/yum.pid: another copy is running as pid:3355

使用yum命令时，出现：

Existing lock /var/run/yum.pid: another copy is running as pid:3355.

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

The other application is: yum-updatesd-he

……

主要原因就是yum在自动更新 只要关掉他就可以了

解决方案：

直接输入  rm -f    /var/run/yum.pid

或者：      /etc/init.d/yum-updatesd stop

也可以等更新完了再进行安装
