我目前正在Windows Server 2008 R2上运行Artifactory Professional 4.0.2 rev 40009的一个实例

我已在Artifactory中配置为远程Yum存储库

我已经在linux服务器上配置了yum以指向这个artifactory实例

当我运行命令时：

yum install -y epel-release

在Artifactory中切换缓存并删除远程存储库的内容可以解决这个问题，但它会不断重复出现，我们正在寻找一个永久性的解决方案

升级到v5.1.4后，此问题再次出现。缓存保留期缩短为10秒，希望这会增加索引文件正确更新的可能性，但没有效果，我们必须删除repodata文件夹的内容并将缓存作为一种解决方法

我可以看到（上次修改：2017年3月29日18:05）上repomd.xml的哈希与Artifactory中相同文件的哈希不匹配（上次修改：2017年3月29日05:05）。文件大小也不一致

由于索引文件过期，这导致某些yum安装失败-

编辑：我注意到存储库中配置了同步属性。禁用该选项后，跟踪输出如下所示。似乎缓存的repomd文件的时间戳与远程文件相同，但文件内容不同（mirror.centos.org中的修订号为1463896289，而Artifactory中的修订号显示为1490724196）

编辑：我注意到存储库中配置了同步属性。禁用该选项后，跟踪输出如下所示。似乎缓存的repomd文件的时间戳与远程文件相同，但文件内容不同（mirror.centos.org中的修订号为1463896289，而Artifactory中的修订号显示为1490724196）

您是如何配置远程存储库的？您是如何配置您的yum的？@JBaruch谢谢您的回答，我已经用infoLooks更新了这个问题，乍一看很好。请尝试将url粘贴到浏览器中，看看它是否仍然是404？如果是，请在URL末尾添加
？跟踪
，并查看结果。@JBaruch我已清除缓存并删除内容。我会密切关注它，如果它再次出现在回购中，我会用
？trace
浏览url并将其发布到这里。问题今天在同一个存储库中再次出现，我上次为该回购删除缓存和内容已经两周了。尝试执行“yum安装-y epel发行版”时，会出现“…primary.sqlite.bz2:[Errno 14]HTTP错误404-未找到”。如果我在url末尾使用？trace进行浏览，则输出为：您是如何配置远程存储库的？您是如何配置您的yum的？@JBaruch感谢您的回复
