失败的脚本是：'./1-prereqs'

我已将它注册到RedHat网络，并且我到处搜索以找到此错误的解决方案，但没有运气。

它看起来像缺少安装Nagios所需的epel-release。 你试过做sudo yum install epel-release吗？

那将是我最大的猜测，根据您的线路：

Error: Cannot retrieve repository metadata (repomd.xml) for repository: epel. Please verify its path and try again RESULT=1

The script that failed was: './1-prereqs'

此外，检查确保代理设置允许该库的连接。有时这会导致下载某些回购数据时出现问题。

因此，简而言之，更新您的epel-release并确保其他任何先决条件都已更新。这可能不会造成伤害：sudo yum install yum-utils以确保yum-utils完全是最新的。

1. 验证卫星或代理服务器具有完全合格的域名，并在的CommonName SSL证书。由Apache使用设置为完全合格的域名。
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来最新版本：yum update yum
5. 清洁客户端系统上的缓存：rm -rf /var/cache/yum/*
