Fiware ContextBroker订阅错误

我已经按照本教程安装了NGSI，将cygnus的版本从0.13更新到了1.7.0：

订阅时出错

查看contextBroker日志可获得以下信息：

我和cygnus在同一台机器上有contextBroker，所以我已经尝试更改服务器和本地主机的notify ip，但它对任何一台都不起作用

如果与localhost一起使用，则使用版本0.13

有什么问题吗

它甚至不能访问cygnus配置文件，因为它无法从contextBroker访问

你好，谢谢你

EDIT1:

我使用fiwareLab机器进行了测试，并删除了预装于YUM-REMOVE-cygnus的cygnus 0.13。然后我用YUM安装CYGNUS-NGSI安装了1.7，并安装了两个包NGSI和common

使用服务cygnus restart重新启动服务表明：

当我在我的服务器上尝试时，我会执行相同的步骤，但在执行服务时，cygnus restart有两个cygnus，即1和2，与vuesta机器中的情况不同，vuesta机器中只有一个cygnus，因此表示端口8081已在使用中

有没有可能这就是问题所在，没有认识到我的NGSI和8081的共同点？还是这很正常

EDIT2

---

我已经解决了两个天鹅座的问题，创建了两个代理1和代理2。我已经删除了其中一个，并且已经在执行服务，cygnus restart只显示一个cygnus。我们正在好转

但我在订阅方面仍然存在同样的问题：

contextBroker日志表明：

当我尝试时：

[root @ UAL-IoF2020 conf] # netstat -np | grep 5050

我什么都不想

当我启动此功能时：

[root @ UAL-IoF2020 conf] # netstat -np | grep 1026
tcp 0 0 150.XXX.XXX.XXX:1026 XXX.XXX.XXX.XXX:50348 ESTABLISHED 5169 / contextBroker

我正在尝试对你的页面进行测试

./notification-json-simple.sh http: // localhost: 5050 / notify myservice myservicepath

并给出以下错误：

[root @ UAL-IoF2020 ngsi-examples] # ./notification-json-simple.sh http: // localhost: 5050 / notify myservice myservicepath
* About to connect () to localhost port 5050 (# 0)
* Trying :: 1 ... Connection refused
* Trying 127.0.0.1 ... Connection refused
* could not connect to host
* Closing connection # 0
curl: (7) could not connect to host

它给人的印象是，在5050年，我什么也听不见

有什么线索吗

cygnus-ngsi.sinks = mysql-sink
cygnus-ngsi.channels = mysql-channel

您发布的最后一个错误日志是密钥：另一个正在运行的进程正在侦听TCP/5050端口。最有可能的是，之前的天鹅座没有正确停止/杀死

我必须安装天鹅座通用手册吗

阅读文档（）它写道：

Cygnus NGSI基于Apache Flume，通过Cygnus common使用，Cygnus NGSI依赖于Apache Flume

---

我想你需要安装cygnus common。

我已经解决了这个问题。 在cygnus_instance_1.conf的配置文件中，您必须使用cygnus ngsi重命名cygnusagent代理

对于安装，我只需遵循以下步骤

安装ContextBroker

安装MongoDB（用于contextBroker）以 工作）

安装天鹅座ngsi，这反过来又自动安装 天鹅座普通

复制agent_ngsi.conf.template并将其重命名为 agent_1.conf

将cygnus_instance.conf.template复制到cygnus_instance_1.conf

将代理从cygnus_instance_1.conf重命名为cygnus ngsi，并在上面创建配置文件（agent_1.conf）

所有这些都是通过Yum安装，通过RPM，我不必安装apacheflume或任何东西，这样它就可以自动完成所有事情

---

我希望这能有所帮助，谢谢。

Orion报告该错误意味着它无法到达通知端点。您是否测试了端点是否正常（例如，使用

telnet

连接到该主机以及Orion运行的主机的端口）？天鹅座的日志里有什么痕迹吗？Cygnus是否配置为在5050中侦听（请检查Cygnus配置）？您发布的最后一个错误日志是关键：有另一个正在运行的进程正在侦听TCP/5050端口。最有可能的是，之前运行的Cygnus没有正确停止/杀死。

netstat-np | grep5050

应该显示Cygnus进程。否则，

通知json simple.sh

失败是正常的，因为您的主机中没有人在听5050。我想我也是jajaja，我感觉很沉重，但我如何解决它？我安装了cygnus并配置了代理，我不知道还能做什么：（若要从0执行安装，我已执行以下步骤：yum install contextBroker yum install cygnus ngsi。我是否必须安装cygnus common manual？或类似的样式？我不知道还有什么可以解决此问题。@fgalan若要从0执行安装，我已执行以下步骤：y）um install contextBroker yum install cygnus ngsi不再。我必须安装cygnus common手册吗？或者类似的样式吗？我不知道还有什么可以解决这个问题当安装

cygnus ngsi

时，

cygnus common

作为依赖项安装。一旦安装，除了confi之外，无需执行其他操作咕噜咕噜。
