百胜正在报告401未经授权的错误

我有两个非常相似的EC2实例。 其中之一是给我这个问题。

Yum在一台服务器上完全按照预期工作，而另一方面，无论我要求yum为我做什么，我都会收到401个错误。

这里有一个例子：

yum repolist -v | grep baseurl 

其输出：

• 在之前的条件之前，try_files服务会退回
• EC2ConfigSettings中的随机密码设置不起作用
• AWS负载均衡器不会转发Cookie
• Elastic Beanstalk中的LEMP堆栈？
• AWS EC2现货实例和地址限制

One of the configured repositories failed (Red Hat Update Infrastructure 2.0 Client Configuration Server 7), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Run the command with the repository temporarily disabled yum --disablerepo=rhui-REGION-client-config-server-7 ... 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable rhui-REGION-client-config-server-7 or subscription-manager repos --disable=rhui-REGION-client-config-server-7 5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=rhui-REGION-client-config-server-7.skip_if_unavailable=true failure: repodata/repomd.xml from rhui-REGION-client-config-server-7: [Errno 256] No more mirrors to try. https://rhui2-cds01.us-west-2.aws.ce.redhat.com/pulp/repos//rhui-client-config/rhel/server/7/x86_64/os/repodata/repomd.xml: [Errno 14] HTTPS Error 401 - Unauthorized https://rhui2-cds02.us-west-2.aws.ce.redhat.com/pulp/repos//rhui-client-config/rhel/server/7/x86_64/os/repodata/repomd.xml: [Errno 14] HTTPS Error 401 - Unauthorized 

而在不同的EC2实例上输出相同的命令：

 Repo-baseurl : https://rhui2-cds01.us-west-2.aws.ce.redhat.com/pulp/repos//rhui-client-config/rhel/server/7/x86_64/os/ Repo-baseurl : https://rhui2-cds02.us-west-2.aws.ce.redhat.com/pulp/repos//content/dist/rhel/rhui/server/7/7Server/x86_64/os/ Repo-baseurl : https://rhui2-cds02.us-west-2.aws.ce.redhat.com/pulp/repos//content/dist/rhel/rhui/server/7/7Server/x86_64/rh-common/os/ 

第一个输出中提到的所有解决scheme似乎并不相关，因为这两个机器上的存储库的设置是相同的。

这是一个SELinux的configuration问题？ 我已经在有问题的机器上禁用了它。

我的/etc/yum.conf文件在两台机器上是相同的：

 [main] cachedir=/var/cache/yum/$basearch/$releasever keepcache=0 debuglevel=2 logfile=/var/log/yum.log exactarch=1 obsoletes=1 gpgcheck=1 plugins=1 installonly_limit=3 

我该如何解决这个问题并安装新的软件包？

 curl http://169.254.169.254/latest/dynamic/instance-identity/document | grep billingProducts 

 To workaround the issue please try one of these two options: 1- From the modified instance ( if you still have it ) create an AMI directly. 2- If the only source that you have is the snapshot then take these steps: - Launch a new instance from a good RHEL AMI, stop and detach the root EBS volume. - Stop the broken instance, detach all EBS volumes and attach to the new instance and restart ( remembering to associate the broken instance's EIP if applicable ) - Alternatively you could snap-shot the broken instance's EBS volumes, and attach volumes created from these snapshots to the new instance. - Verify billingProducts value is present by running curl http://169.254.169.254/latest/dynamic/instance-identity/document
