近期从百度云盘上下载下来rhel7.2(MaiPo)，之后，开始解决怎么在rhel7.2上使用非红帽官方的yum仓库，终于解决了。解决方法如下：
1、网易163的yum repo:
在/etc/yum.repos.d/下面新建163.repo:
total 8
-rw-r--r--. 1 root root 87 Aug 5 01:13 163.repo
-rw-r--r--. 1 root root 358 Aug 1 00:27 redhat.repo
[zqf@rhel7-2 yum.repos.d]$ cat 163.repo
[163]
name=163
baseurl=http://mirrors.163.com/centos/7/os/x86_64/
gpgcheck=0
enabled=1
就OK了，下面安装nvme试试：
[zqf@rhel7-2 r12058]$ sudo yum -y install nvme-cli

2、epel源：
[zqf@rhel7-2 yum.repos.d]$ sudo rpm -vih http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-10.noarch.rpm
[sudo] password for zqf:

装完这个rpm包之后就自动生成了epel.repo和epel-testing.repo
[zqf@rhel7-2 yum.repos.d]$ ll
total 16
-rw-r--r--. 1 root root 87 Aug 5 01:13 163.repo
-rw-r--r--. 1 root root 951 Jun 24 11:04 epel.repo
-rw-r--r--. 1 root root 1050 Jun 24 11:04 epel-testing.repo
-rw-r--r--. 1 root root 358 Aug 1 00:27 redhat.repo
注意http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-10.noarch.rpm这个链接有可能会变，因为在不断更新，比如之前几个月就是http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm
