Question

当我尝试转动任何yum命令时，我得到了以下消息。我在发生此错误之前禁用并启用了SSL。由于系统说RHNS-CA-CERT已过期，我删除了证书并使用wget命令下载了它。然后我尝试使用yum命令更新证书，这就是问题开始的地方。

以下是错误消息：

好吧，我的猜测是你正在对抗RHN Classic（rhn.redhat.com）。有错误修复这个过期的证书，这里有相关的知识基础文章：

与RHN的系统连接失败，＆＃34;证书已过期，或证书验证失败＆＃34;错误 https://access.redhat.com/solutions/353033

使用IOError: unsupported XML-RPC protocol追踪会让我猜测serverURL中的/etc/sysconfig/rhn/up2date不正确。它应该是这样的：

serverURL=https://xmlrpc.rhn.redhat.com/XMLRPC

IOError：运行yum命令时不支持的XML-RPC协议
