我试图在nagiosxi的一个测试流变框上安装linux nrpe代理，以便进行监视，并且当我运行fullinstall脚本Im时，得到以下错误

[root@nrpetest2 linux-nrpe-agent]# ./fullinstall

失败的脚本是：'./1-prereqs‘

我也在RedHat网络上注册了它，我到处寻找解决这个错误的方法，但是都没有成功。

看起来，您缺少了nagios安装所需的epel-release。你试过做sudo yum install epel-release吗？

这将是我最大的猜测，根据你的台词：

错误:无法为存储库检索存储库元数据(repomd.xml)：epel。请验证其路径，然后重试失败的RESULT=1The脚本：'./1-prereqs‘

此外，检查以确保您的代理设置允许连接到该存储库。有时，这会导致下载某些回购数据时出现问题。

所以，简单地说，更新你的epel-发行版，并确保任何其他的预先需求已经更新.这样做可能不会有什么坏处：sudo yum install yum-utils确保yum-utils完全是最新的。

更新：从：访问红帽

1. 验证卫星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. 将yum更新为最新版本：yum update yum
5. 清除客户端系统上的缓存：rm -rf /var/cache/yum/*
