我可以通过 yum 安装以下命令 ntp rpm，但在 yum 安装之前，我收到如下失败行：

 yum install ntp

发生什么事了？

答案1

域 linux.sys65dns.com 无效。如果它来自镜像列表，请尝试yum clean all并重试。

答案2

故障排除步骤（假设这是您本地托管的存储库）：

  1. 回到顶部yum clean all并尝试再次安装 ntp。出于测试目的，尝试安装不同的包。
  2. 如果上述操作失败，请尝试 ping 你的服务器：ping linux02.sys65dns.com
  3. 如果出现上述情况，请尝试在 Web 浏览器中打开它，以检查端口 80 是否正常工作或者您是否也可以进行 telnet。
  4. 如果没有，请检查服务器上的 apache 服务以及端口 80 是否打开。您还可以检查 ports.conf 以查看 apache 是否配置为在端口 80 或其他端口上运行。
