我尝试通过yum在我的服务器上安装mongodb@3.4，按照MongoDB Doc上的步骤。首先，我在**/etc/yum.repos.d/目录中创建了一个名为mongodb-org-3.4.repo**的文件，并复制了下面的文本。

[mongodb-org-3.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/amazon/2013.03/mongodb-org/3.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc

然后我尝试了sudo yum install mongodb-org，但出现了错误。

One of the configured repositories failed (MongoDB),
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. Disable the repository, 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 mongodb-org-3.4

4. 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=mongodb-org-3.4.skip_if_unavailable=true

failure: repodata/repomd.xml from mongodb-org-3.4: [Errno 256] No more mirrors to try.

之后，我尝试了yum repolist，发现MongoDBget 0的状态。

不知道那个回购还有效吗？谢谢~
