2 现象分析

[root@localhost software]# netstat -lntp | grep -i 3289
[root@localhost software]# ll /proc/3289 | grep -i CWD
lrwxrwxrwx. 1 root root 0 Jun 16 09:34 cwd -> /
[root@localhost software]# ps -ef | grep -i 3289
root       3289   2040  2 09:22 ?        00:00:17 /usr/bin/python /usr/share/PackageKit/helpers/yum/yumBackend.py get-updates none
root       3721   3289  3 09:33 ?        00:00:02 /usr/bin/python /usr/libexec/urlgrabber-ext-down
root       3736   3508  0 09:34 pts/1    00:00:00 grep --color=auto -i 3289

3 解决方法

• 方法1: kill掉该yum进程

[root@localhost software]# kill -9 <pid>

• 方法2：通过强制关掉yum进程

rm -f /var/run/yum.pid

然后，就可以重新使用yum了。
