Fiware 天鹅座宇宙积分
我们成功地整合了idas天鹅座猎户座的流量，一切都很完美。（谢谢你的帮助，弗朗西斯科） 现在我们想将Cosmos添加到集成中，我已经用您的答案配置了天鹅座（Cosmos配置中添加了以*开头的部分） 当我启动Cygnus时，我们得到这个错误消息Fiware 天鹅座宇宙积分,fiware,fiware-cygnus,fiware-cosmos,Fiware,Fiware Cygnus,Fiware Cosmos,我们成功地整合了idas天鹅座猎户座的流量，一切都很完美。（谢谢你的帮助，弗朗西斯科） 现在我们想将Cosmos添加到集成中，我已经用您的答案配置了天鹅座（Cosmos配置中添加了以*开头的部分） 当我启动Cygnus时，我们得到这个错误消息 [root@idas-new centos]# tail -500f nohup.out Warning: No configuration directory set!
