centos 下yum命令无法正常安装docker问题

zp7412

　　docker安装前检查你对应centos版本，一般要高与3.8版本才支持
root@bogon ~]# uname -a
Linux bogon 3.10.0-693.21.1.el7.x86_64 #1 SMP Wed Mar 7 19:03:37 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
在安装docker时出现如下错误信息，
[root@bogon ~]# yum -y install docker
Loaded plugins: fastestmirror, langpacks
Existing lock /var/run/yum.pid: another copy is running as pid 2310.
Another app is currently holding the yum lock; waiting for it to exit...
The other application is: PackageKit

State  : Sleeping, pid: 2310
　　排查问题方式
已经有一个yum进程在运行了，使用kill干掉它：
　　[root@bogon ~]# kill -s -9 2310  -----------------发现kill 无法起效果
bash: kill: -9: invalid signal specification
　　暴力方式，可以通过强制关掉yum进程
[root@bogon ~]# rm -f /var/run/yum.pid
　　然后重新运行命令安装，
[root@bogon ~]# yum -y install docker
