无法检索存储库的存储库元数据：epel (rhel 6.6)

Question

我试图在其中一个测试 rhel 盒子上安装 linux nrpe 代理以供 nagiosxi 监控，当我运行 fullinstall 脚本时，我收到以下错误

[root@nrpetest2 linux-nrpe-agent]# ./fullinstall
============================
Nagios Linux Agent Installer

This script will install the Nagios Linux Agent by executing all necessary
sub-scripts.

IMPORTANT: This script should only be used on a clean installed system:

   RedHat Enterprise, CentOS, Fedora, or Oracle
   OpenSUSE or SUSE Enterprise
   Ubuntu or Debian

Do NOT use this on a system running any other distro or that
does not allow additional package installation.

失败的脚本是：'./1-prereqs'

我也在 RedHat 网络上注册了它，我到处搜索以找到解决此错误的方法，但没有运气。

您似乎缺少安装 nagios 所需的 epel-release。 你试过sudo yum install epel-release吗？

根据您的说法，这将是我最大的猜测：

错误：无法检索存储库的存储库元数据 (repomd.xml)：epel。请验证其路径并重试 RESULT=1

失败的脚本是：'./1-prereqs'

另外，检查以确保您的代理设置允许连接到该存储库。有时这会导致下载某些 repo 数据出现问题。

因此，简而言之，更新您的 epel-release 并确保任何其他先决条件都已更新。这样做可能不会有什么坏处：sudo yum install yum-utils 以确保 yum-utils 完全是最新的。

1. 验证 Satellite 或代理服务器是否具有完全限定的域名，以及 SSL 证书中的 CommonName。 Apache 使用的域名设置为完全限定域名。
2. 验证 ssl.conf 文件是否指向正确的文件。
   grep ^SSLCert /etc/httpd/conf.d/ssl.conf
3. 如果系统指向代理，请检查以确保 /etc/sysconfig/rhn/up2date 配置了正确的 http_proxy 信息。
   httpProxy=http_proxy_fqdn or ip_address:port
4. 更新 yum 到最新版本：yum update yum
5. 清除客户端系统上的缓存：rm -rf /var/cache/yum/*
