Redhat7 yum 无法使用

错误信息
[root@micocube ~]# yum install gcc-c++
Loaded plugins: product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
There are no enabled repos.
Run "yum repolist all" to see the repos you have.
To enable Red Hat Subscription Management repositories:
subscription-manager repos --enable
To enable custom repositories:

查看redhat 7.0系统本身所安装的那些yum软件包
[root@micocube ~]# rpm -qa | grep yum
yum-rhn-plugin-2.0.1-10.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-3.4.3-158.el7.noarch
卸载这些软件包
[root@micocube ~]# rpm -e yum-rhn-plugin-2.0.1-10.el7.noarch --nodeps
[root@micocube ~]# rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps
[root@micocube ~]# rpm -e yum-3.4.3-158.el7.noarch --nodeps
下载centos的yum 相关 rpm包,包下载地址，版本请从包下载地址获取最新的，可以用wget下载
python-kitchen-1.1.1-5.el7.noarch.rpm
python-chardet-2.2.1-1.el7_1.noarch.rpm
yum-3.4.3-161.el7.centos.noarch.rpm
yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
yum-utils-1.1.31-50.el7.noarch.rpm
yum-updateonboot-1.1.31-50.el7.noarch.rpm
yum-plugin-fastestmirror-1.1.31-50.el7.noarch.rpm

安装软件包
rpm -ivh python-*
rpm -ivh yum-*

切换到/etc/yum.repos.d/目录
从这里下载repo文件到/etc/yum.repos.d/目录
比如wget http://mirrors.aliyun.com/repo/Centos-7.repo
清除缓存
yum clean all
可以用yum search vim测试

这个Red Hat Subscription Manager订阅管理器，它会让你一直register，解决办法:禁用就好
因此，为了不冲突，可以如下操作:停止掉该插件的使用，在配置文件中把enable=0即可。
[root@micocube ~] vim /etc/yum/pluginconf.d/subscription-manager.conf
[main]
enabled=0 #将它禁用掉

但是我在执行yum makecache时报错，报错信息如下：

Loaded plugins: fastestmirror, langpacks, priorities
Repository epel is listed more than once in the configuration
Cleaning repos: base epel extras updates
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos

[root@hadoop01 yum.repos.d]# yum makecache

Trying other mirror.

【解决方法】
在网上找了好多帖子，都没能解决我的问题，后来看到是HTTP请求失败，尝试本地访问之前wget下来的 CentOS-Base.repo 发现其中的：

http://mirrors.aliyun.com/centos/$releasever/os/$basearch/

等URL通过http的形式根本无法访问，此时将变量$releasever改为7（我的系统是centos 7），发现可以访问了，顺便将所有的变量$releasever都改为7。感觉这个变量$releasever根本就没起作用呀。

改完之后，执行yum clean all 以及 yum makecache 成功。
