<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>二、原因：</span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>字面意思是说"另外一个程序给yum加了锁，要等到 yum-updatesd 程序退出以后才可以进行"， yum-updatesd是系统自带的一个提供系统更新的服务，安装文件也叫做yum-updatesd，这个服务默认是自动启动的（init 5），他运行的时候会自动给yum加锁，这就导致了开机后不能手动进行yum了。</span></p>
