Try "searching" for the correct package name in the reps by using yum list
尝试使用 yum list 在代表中“搜索”正确的包名称
yum list nmap
I guess the correct package name and install command is:
我猜正确的包名和安装命令是：
yum install nmap.x86_64
You can also do a "yum search somename"
你也可以做一个“yum search somename”

Red Hat doesn't use the /etc/yum.repos.d directory for official packages so the answer won't be in there. It will use the subscription plugin placed in /etc/yum/pluginconf.d.
Red Hat 不将 /etc/yum.repos.d 目录用于官方软件包，因此答案不会在那里。它将使用放置在 /etc/yum/pluginconf.d 中的订阅插件。
You mentioned that the RHEL host is new. You will need to make sure your subscription is valid or yum will fail silently.
您提到 RHEL 主机是新的。您需要确保您的订阅有效，否则 yum 将无声无息地失败。
You can use the subscription-manager listcommand to gain info regarding subscriptions.
您可以使用该subscription-manager list命令获取有关订阅的信息。

If you have OS image in your lab or any location you can try this for some RPMS
如果您的实验室或任何位置有操作系统映像，您可以为某些 RPMS 尝试此操作
vim /etc/yum.repos.d/rhel.repo
[rhel]
name=rhel
baseurl=http://172.25.5.25/osimages/rhel7.2_64bit
enabled=1
gpgcheck=0
Then do yum clean all
然后做 yum clean all
baseurl is the location where your OS image is available. No subscription is needed, it is reusing your OS image
baseurl 是您的操作系统映像可用的位置。无需订阅，它正在重用您的操作系统映像

Centos has done it for you.
Centos已经为你做到了。
Create a repo file in /etc/yum.repos.d as
在 /etc/yum.repos.d 中创建一个 repo 文件作为
vi /etc/yum.repos.d/myrepo.repo
Then paste this in this file:
然后将其粘贴到此文件中：
[centos]
name=CentOS-7
baseurl=http://ftp.heanet.ie/pub/centos/7/os/x86_64/
enabled=1
gpgcheck=1
gpgkey=http://ftp.heanet.ie/pub/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7
Saving it with wq! now run
用 wq 保存它！现在运行
yum repolist
Check if you can install any package (say nmap)
检查您是否可以安装任何软件包（例如 nmap）
yum install nmap -y
Enjoy!!!

In my case, I was trying to install OpenJDK using yum; sudo yum install -y java-1.8.0-openjdk-develbut received an error message stating that a dependency was unavailable:
就我而言，我试图使用 yum 安装 OpenJDK；sudo yum install -y java-1.8.0-openjdk-devel但收到一条错误消息，指出依赖项不可用：
---> Package java-1.8.0-openjdk-headless.x86_64 1:1.8.0.201.b09-1.el6_10 will be installed
--> Processing Dependency: pcsc-lite-devel(x86-64) for package: 1:java-1.8.0-openjdk-headless-1.8.0.201.b09-1.el6_10.x86_64
--> Finished Dependency Resolution
Error: Package: 1:java-1.8.0-openjdk-headless-1.8.0.201.b09-1.el6_10.x86_64 (rhel-6-server-rpms)
Requires: pcsc-lite-devel(x86-64)
**********************************************************************
yum can be configured to try to resolve such errors by temporarily enabling
disabled repos and searching for missing dependencies.
To enable this functionality please set 'notify_only=0' in /etc/yum/pluginconf.d/search-disabled-repos.conf
**********************************************************************
I resolved this by following the suggestion please set 'notify_only=0' in /etc/yum/pluginconf.d/search-disabled-repos.confand then ran the yum command again. This time yum loaded a bunch of [previously disabled] repos and searched through them, finally reporting success and this message:
我按照建议解决了这个问题please set 'notify_only=0' in /etc/yum/pluginconf.d/search-disabled-repos.conf，然后再次运行 yum 命令。这次yum加载了一堆[以前禁用]的repos并搜索了它们，最终报告成功并显示以下消息：
*******************************************************************
Dependency resolving was successful thanks to enabling these repositories:
rhel-6-server-optional-rpms
*******************************************************************
So there was no ignored *-develrepo, but still doing this worked. For clearance, the explicitly ignored repos are: ignored_repos=*debug-rpms *source-rpms *beta-rpms
所以没有被忽略的*-devel回购，但这样做仍然有效。为了清除，明确忽略的回购是：ignored_repos=*debug-rpms *source-rpms *beta-rpms
..so that worked, but I'm still no wiser on the mechanics of this..
..所以这行得通，但我对这个机制仍然不了解..
