问题描述
在此教程之后，我通过安装NGSI将cygnus从0.13版本更新到1.7.0:
I've updated cygnus from version 0.13 to 1.7.0 by installing NGSI following this tutorial:

查看contextBroker日志将给出以下内容:
viewing the contextBroker log gives the following:
$pp[328]:notificationError | msg=Raising alarm NotificationError http://localhost:5050/notify: (curl_easy_perform failed: Couldn't connect to server)
我在与cygnus相同的计算机上安装了contextBroker，因此我已经尝试更改服务器和localhost的notify ip，但不适用于其中的任何一个.
I have contextBroker on the same machine as cygnus so I have already tried to change the notify ip for the server and for localhost and it does not work for any of it.
如果与localhost兼容，则版本为0.13.
with version 0.13 if it works with localhost.
可能是什么问题?
它甚至没有出现在cygnus配置文件中，因为它无法从contextBroker中访问.
It does not even come to cygnus configuration files because it can not access from the contextBroker.
问候，谢谢.
我已通过fiwareLab机器进行了测试，并删除了YUM REMOVE CYGNUS预先安装的cygnus 0.13.然后，我用YUM INSTALL CYGNUS-NGSI安装了1.7，并安装了两个软件包ngsi和common.
I am tested with the fiwareLab machines and removing cygnus 0.13 that comes pre installed with YUM REMOVE CYGNUS. Then I installed 1.7 with YUM INSTALL CYGNUS-NGSI and installed two packages ngsi and common.
通过服务cygnus restart重新启动服务指示以下内容:
Restarting the service with service cygnus restart indicates the following:

这可能是问题所在，并且无法识别我的NGSI，而这就是8081的共同之处吗?还是正常?
Is it possible that this is the problem and that is not recognizing my NGSI and this occupying the 8081 the common? or is this normal?

EDIT2
我已经解决了两个天鹅座的问题，创建了两个agent_1和agent_2.我已删除其中之一，并且已经执行了服务天鹅座重启，仅出现了一个天鹅座.我们越来越好了.
I have already solved the problem of two cygnus, had two agent_1 and agent_2 created. I have deleted one of them and already performing service cygnus restart appears only one cygnus. We are getting better.
但是订阅仍然有相同的问题:
But I still have the same problem with the subscriptions:
contextBroker日志指示:
The contextBroker log indicates:
msg = Raising alarm NotificationError http: // localhost: 5050 / notify: (curl_easy_perform failed: could not connect to server)
当我尝试时:
[root @ UAL-IoF2020 conf] # netstat -np | grep 5050
我什么也没想.
当我启动它时:
[root @ UAL-IoF2020 conf] # netstat -np | grep 1026
tcp 0 0 150.XXX.XXX.XXX:1026 XXX.XXX.XXX.XXX:50348 ESTABLISHED 5169 / contextBroker
我正在尝试对您的页面进行测试.
I am trying to launch a Test of your page.
./notification-json-simple.sh http: // localhost: 5050 / notify myservice myservicepath
并给我以下错误:
[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
给人的印象是，在5050年我什么都听不到.
It gives the impression that in the 5050 I have nothing listening.
有什么线索吗?
cygnus-ngsi.sources = http-source
cygnus-ngsi.sinks = mysql-sink
cygnus-ngsi.channels = mysql-channel

cygnus-ngsi.sources.http-source.interceptors.gi.grouping_rules_conf_file = /usr/cygnus/conf/grouping_rules.conf
推荐答案
我已经解决了这个问题.该文件位于cygnus_instance_1.conf的配置文件中，您必须通过cygnus-ngsi重命名cygnusagent代理.
I have already solved the problem.It was in the configuration file of cygnus_instance_1.conf, you had to rename the cygnusagent agent by cygnus-ngsi.
对于安装，我只需遵循以下步骤即可.
For installation, I have simply followed these steps.
- 安装ContextBroker.
- 安装MongoDB(用于contextBroker到工作).
-
安装cygnus-ngsi，这将自动安装天鹅座常见.
- Install ContextBroker.
- Install MongoDB (for contextBroker towork).
Install cygnus-ngsi, this in turn installed automaticallycygnus-common.
复制agent_ngsi.conf.template并将其重命名为agent_1.conf
Copy the agent_ngsi.conf.template and rename it withagent_1.conf
将cygnus_instance.conf.template复制到cygnus_instance_1.conf
Copy the cygnus_instance.conf.template to cygnus_instance_1.conf
将代理从cygnus_instance_1.conf重命名为cygnus-ngsi和上面创建的配置文件(agent_1.conf)
Rename the agent from cygnus_instance_1.conf to cygnus-ngsi and the configuration file created above (agent_1.conf)
这一切都是通过Yum Install，RPM进行的，我不必安装apache flume或任何东西，这样就可以自动完成所有操作.
All this has been with Yum Install, with RPM, I have not had to install apache flume or anything, this way it does everything automatically.
我希望这会有所帮助，谢谢.
I hope this helps and thanks.
