有時候使用 yum 相關功能時，會出現 yum lock 問題，而來源是 PackageKit
[root@localhost ~]# yum list | grep hadoop
Existing lock /var/run/yum.pid: another copy is running as pid 3896.
Another app is currently holding the yum lock; waiting for it to exit...
The other application is: PackageKit

有時候 yum lock 沒多久就解開了，有時候會等很久，筆者碰過超過一天仍在鎖住的情況。
找出 PackageKit
[root@localhost ~]# ps aux | grep PackageKit
root 3896 0.0 4.8 367904 49592 ? S 01:17 0:00 /usr/bin/python /usr/share/PackageKit/helpers/yum/yumBackend.py get-packages unknown
root 29945 0.0 0.0 103256 840 pts/1 S+ 08:51 0:00 grep PackageKit
[root@localhost ~]#
用 kill -9 去刪除 process
[root@localhost ~]# kill -9 3896
檢查，成功刪除 process 了
[root@localhost ~]# ps aux | grep PackageKit
root 29955 0.0 0.0 103252 836 pts/1 S+ 08:53 0:00 grep PackageKit
再次執行，仍被 lock
[root@localhost ~]# yum list | grep hadoop
Existing lock /var/run/yum.pid: another copy is running as pid 3896.

一般程序執行時候，lock file 會放在 /var/lock/subsys/ 目錄，但此處沒有 yum 或 python 或 PackageKit
[root@localhost ~]# ls /var/lock/subsys/
abrt-ccpp auditd crond local network rpc.statd
abrtd autofs cups lvm2-monitor NetworkManager rsyslog
acpid blk-availability haldaemon messagebus postfix sshd
atd certmonger ip6tables netfs rpcbind udev-post
[root@localhost ~]#
從剛剛的訊息
Existing lock /var/run/yum.pid: another copy is running as pid 3896.
yum 的 lock file 是 /var/run/yum.pid，用 rm -fr 指令刪除
[root@localhost ~]# rm -fr /var/run/yum.pid
再次執行，不再有 lock 訊息
[root@localhost ~]# yum list | grep hadoop
[root@localhost ~]#
PackageKit 是甚麼？它是 GNOME X-Window 底下負責管理/安裝和移除套件的工具，套件名稱為 gnome-packagekit。
Fedora 由 9 開始採用 PackageKit 系統 協助 YUM 作為管理套件，而 gnome-packagekit 亦取替 Pirut 成為 Fedora 的預設套件管理工具。
[root@localhost ~]# yum list | grep gnome-packagekit
gnome-packagekit.x86_64 2.28.3-7.el6 @anaconda-CentOS-201311272149.x86_64/6.5
gnome-packagekit-extra.x86_64 2.28.3-7.el6 base
[root@localhost ~]#
如果不想再碰到 PackageKit 產生 yum lock，且你不會在 GNOME X-Window 底下用圖形介面 (GUI) 管理/安裝和移除套件，可以考慮把它移除。
[root@localhost ~]# yum -y remove gnome-packagekit

有時候強行把 PackageKit 用 kill 刪除，會出問題
[root@localhost ~]# yum -y install iftop
