我在软件映像CentOS-7-x64上安装了cygnus 0.8.2,我使用以下方式订阅了orion上下文代理:
(curl 193.48.247.246:1026/v1/subscribeContext -s -S --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Fiware-Service: egmmqtt' --header 'Fiware-ServicePath: /egmmqttpath' -d @- | python -mjson.tool) <<EOF

"notifyConditions": [
{
"type": "ONCHANGE",
"condValues": [
"switch2A"
]
}
],
"throttling": "PT1S"
}
EOF
没有通知天蝎座,我在orionContextBroker日志中收到此错误:
time=2015-10-06T17:43:37.898CEST | lvl=WARNING | trans=1443447780-161-00000000423 | function=sendHttpSocket | comp=Orion | msg=clientSocketHttp.cpp[358]: Notification failure for 193.48.247.223:5050 (curl_easy_perform failed: Couldn't connect to server)
我不知道为什么在相关的公共IP地址下没有达到天鹅座实例。实际上我无法从Orion实例ping cygnus机器实例。我错过了什么想法?谢谢!
答案 0 :(得分:2)
在天鹅座实例的安全规则中,天鹅座正在听的端口(在我的情况下是5050)必须是开放的,所以猎户座可以到达天鹅座实例。
