yum 更新后清空 rpm 文件

yum 更新后清空 rpm 文件

在极少数情况下,运行 yum update 后,会安装一个或多个包含 0 大小文件的软件包,并且在重新安装受影响的软件包后问题会得到解决。

我本来相信外部因素,但时间戳始终与已安装的软件包相同。

我使用的是 Oracle Linux 7.9

uname -r
5.4.17-2102.200.13.el7uek.x86_64

rpm -q rpm --last
rpm-4.11.3-48.el7_9.x86_64                    Sun 05 Jun 2022 05:07:48 AM UTC

rpm -q yum --last
yum-3.4.3-168.0.3.el7.noarch                  Fri 21 May 2021 02:23:50 PM UTC

例如。:

rpm -q gzip --last
gzip-1.5-11.el7_9.x86_64                      Sat 13 Aug 2022 05:30:27 AM UTC

发现了问题,所以我正在回答我自己的问题。

重新启动之前运行“同步”。

事实证明,Oracle Linux 7.9 无法与 AWS API 重新启动良好配合。我使用的更新程序工具执行了两个步骤:yum 更新和从 AWS API 重新启动。这样做时,内核没有时间将内存中缓冲的所有数据同步到磁盘,因此新创建的文件要么根本没有保存,要么大小为 0,其中没有内容。

仅当从 AWS API 执行重新启动过程时才会出现此问题,因为使用操作系统重新启动命令不会重现该问题。
