第一步，查找yum进程的PID
ps -ef | grep yum
得到下面的结果：
root 1985 1650 0 16:42 pts/0 0:00 grep --color=auto yum
root 5804 1 0 2017 ? 00:00:00 /usr/bin/python /usr/bin/yum update
其中5804就是yum进程的PID
第二步，使用kill命令杀掉进程：
kill -9 5804
2.删除yum的pid文件
rm -f /var/run/yum.pid
示例操作:
第一种情况，通过杀掉yum进程的方式来解决问题。
ps -ef | grep yum
# 得到yum进程的PID
kill -9 5804
第二种情况，通过删除yum的pid文件来解决问题。
rm -f /var/run/yum.pid
