使用openstack（版本OpenStack-Rocky）本地源安装时，发现缺少安装包报ERRO，报错如下

Pre installing Puppet and discovering hosts' details[ ERROR ]

ERROR : Failed to run remote script, stdout: Loaded plugins: fastestmirror

······

stderr: Warning: Permanently added '192.168.100.11' (ECDSA) to the list of known hosts.

解决办法
挂载本地的系统光盘，再搭建一个本地yum源即可解决
