使用 yum 命令从 epel 失败
Failure from epel with yum command
感谢您来尝试解决我的问题。我已经看到很多关于使用 yum 命令失败的解决方案，但直到现在，这些解决方案对我不起作用。
首先，这里有一些关于情况的信息：
我正在使用 RedHat Linux 7.2-11，使用代理（因为我公司的网络非常安全）所以我已经修改了 etc/sysconfig/rhn/up2date、etc/wgetrc 和 [=45= .conf 文件，包含 http_proxy、proxy_user 和 proxy_password !
然后，我以 root 身份连接，并尝试下载 python-pip 执行以下命令：
sudo yum install python-pip
我有以下错误：
No package python-pip available
在 python-pip 之前尝试安装 epel-release 时出现完全相同的错误。
然后我做了以下：
yum install httpd php php-gd php-mysql
最后，我在 /tmp 中使用这些命令下载并安装了 epel-release :
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum install epel-release-latest-7.noarch.rpm
一切顺利！
问题来了。之后，我再次尝试了这些命令：
sudo yum install python-pip
sudo yum install -y python-pip
第一个错误是：
One of the configured repositories failed (Unknown),
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:
........some tips (1 to 5)........
Cannot retrieve metalink for repository: epel/x86_64. Please verify its path and try again
所以我按照一些说明修改了 epel.repo 和 epel-testing.repo 注释所有 "mirror" 行并取消注释所有 "baseurl" 行。
所以，现在，当我再次尝试安装 python-pip 时，出现了这个错误：
Loaded plugins: rhnplugin, search-disabled-repos

请问您知道如何解决这个问题，或者您有什么想法吗？
这似乎是因为代理，但我已经按照消息顶部的说明配置了三个文件。
感谢您的帮助！ :)
您不必在 CentOS-7 机器上手动下载 epel-release。 repo 文件中可能缺少最新的 RPM mirrorlist，这可能调用 baseurl=http:// 而不是 mirrorlist=https://。
解决此问题的方法如下：
# Remove already installed epel-release
yum remove epel-release
OR
rpm -e epel-release
# Install epel-release using YUM
yum install epel-release
# Install python-pip
yum install python-pip
~]# yum install python-pip
