我想使用Fiware cygnus将来自上下文代理的数据保存到CKAN实例中。我已经创建了一个orion上下文代理vm，它是orion-psb-image-R5.4 1.7.0版本和Fiware云上的ckan VM。我开始安装天鹅座天鹅座知道天鹅座是基于天鹅座和天鹅座的。所以，我开始下载fiware-cygnus https://github.com/telefonicaid/fiware-cygnus 然后我开始使用maven 3.2.5成功构建cygnus-common。但是当我开始构建cygnus-ngsi时它失败了，尽管我已经尝试了很多方法来解决这个问题，但是没有人工作。 这是我在细节上所做的事情。
所述安装Apache Flume$ wget http://www.eu.apache.org/dist/flume/1.4.0/apache-flume-1.4.0-bin.tar.gz
tar xvzf apache-flume-1.4.0-bin.tar.gz
$ mv apache-flume-1.4.0-bin APACHE_FLUME_HOME
$ mv APACHE_FLUME_HOME/lib/httpclient-4.2.1.jar APACHE_FLUME_HOME/lib/httpclient-4.2.1.jar.old
$ mv APACHE_FLUME_HOME/lib/httpcore-4.2.1.jar APACHE_FLUME_HOME/lib/httpcore-4.2.1.jar.old
$ mv APACHE_FLUME_HOME/lib/libthrift-0.7.0.jar APACHE_FLUME_HOME/lib/libthrift-0.7.0.jar.old
$ mkdir -p APACHE_FLUME_HOME/plugins.d/cygnus/
$ mkdir APACHE_FLUME_HOME/plugins.d/cygnus/lib
$ mkdir APACHE_FLUME_HOME/plugins.d/cygnus/libext
其次，下载fiware-cygnus并建立cygnus-common：
git clone https://github.com/telefonicaid/fiware-cygnus.git
cd fiware-cygnus/cygnus-common
mvn clean compile exec:exec assembly:single
cp target/cygnus-common-1.7.0-jar-with-dependencies.jar /usr/cygnus/plugins.d/cygnus/libext
mvn install:install-file -Dfile=/usr/cygnus/plugins.d/cygnus/libext/cygnus-common-1.7.0_SNAPSHOT-jar-with-dependencies.jar -DgroupId=com.telefonica.iot -DartifactId=cygnus-common -Dversion=1.7.0 -Dpackaging=jar -DgeneratePom=false
cp target/classes/cygnus-flume-ng /usr/cygnus/bin/cygnus-flume-ng
然后我开始按照以下方式建造天鹅座 -
cd cygnus-ngsi
mvn clean compile exec:exec assembly:single
我在构建它时获得了这些结果：

我将生成的jar文件复制到/usr/cygnus/plugins.d/cygnus/libext，如上面相同的链接中所述，运行：
cp cygnus-common/target/cygnus-common-1.7.0_SNAPSHOT-jar-with-dependencies.jar /usr/cygnus/plugins.d/cygnus/libext
我还将jar文件复制到maven存储库路径，以确保通过运行命令正确设置所有内容
cp cygnus-common/target/cygnus-common-1.7.0_SNAPSHOT-jar-with-dependencies.jar ~/.m2/repository/com/telefonica/iot/cygnus-common/1.7.0
现在我在〜/ .m2 / repository / com / telefonica / iot / cygnus-common / 1.7.0目录下有两个罐子，cygnus-common-1.7.0_SNAPSHOT-jar-with-dependencies.jar和cygnus-common-1.7.0.jar以及usr /包含它们的cygnus / plugins.d / cygnus / libext目录实际上我不知道这两个目录中是否存在两个罐子会产生问题。
我还认为cygnus-ngsi pom.xml文件可能是问题的一部分..这里是cygnus-ngsi的pom.xml：

现在我想知道可能导致这种失败的原因。我想做的就是设置一个cygnus代理来使用ckansink，通过配置agent_.conf文件并提供必要的ckan参数然后启动cygnus。我知道除非天鹅座成功建造，否则这个过程不会完成
编辑：现在，我尝试通过运行
删除所有以前的天鹅座文件sudo rpm -e -vv --allmatches --nodeps --noscripts --notriggers cygnus
sudo rpm -e -vv --allmatches --nodeps --noscripts --notriggers cygnus-ngsi
然后我使用rpm安装了cygnus-common和cygnus-ngsi 1.7.0 并且它们已成功安装。然后我在/usr/cygnus/conf/agent_1.conf文件中配置了必要的ckan参数。
现在的问题是我通过运行
启动天鹅座/usr/cygnus/bin/cygnus-flume-ng agent --conf /usr/cygnus/conf/ -f /usr/cygnus/conf/agent_1.conf -n cygnusagent -Dflume.root.logger=INFO,console
我得到的这些日志只能通过侦听8081的jetty服务器结束，如下所示：

那么，整个配置中是否缺少以及可以修复哪些内容以使httpsource接受我的通知请求？
答案 0 :(得分：2)
从此命令：
cp target/cygnus-common-1.1.0-jar-with-dependencies.jar /usr/cygnus/plugins.d/cygnus/libext
您似乎已经构建了cygnus-common版本1.1.0（是不是？我的意思是，cygnus-common-1.1.0-jar-with-dependencies.jar目录中是否有target/文件？）
然而，在下一个命令中，您尝试安装了cygnus-common release 1.7.0_SNAPSHOT（带依赖项）：
mvn install:install-file -Dfile=/usr/cygnus/plugins.d/cygnus/libext/cygnus-common-1.7.0_SNAPSHOT-jar-with-dependencies.jar -DgroupId=com.telefonica.iot -DartifactId=cygnus-common -Dversion=1.7.0 -Dpackaging=jar -DgeneratePom=false
因此上述命令之一是错误的：两者都必须引用相同的版本。
一个问题：一旦克隆了github repo，您是否按照文档中的说明签出了特定版本？
$ git clone https://github.com/telefonicaid/fiware-cygnus.git
$ cd fiware-cygnus
$ git checkout＆lt; branch＆gt;
这样的<branch>可能是master（最新开发，不推荐），1.7.0（最新官方发布），1.6.0 ...
因此，始终使用所有组件的特定版本，甚至使用适当的文档版本（例如，您发布的文档链接指的是版本1.3.0，而您尝试构建cygnus-common 1.1.0但安装1.7.0 ...）。
PS：有一种简单的方法可以安装最新版本（在撰写本文时，1.7.0）：使用FIWARE repo中的RPM。
编辑1：[修复安装问题并编辑了有关启动问题的问题]
如果你无法向Cygnus发送模拟通知，那是因为Cygnus没有正确启动。您可以在/var/log/cygnus/cygnus.log查看日志并获取更多详细信息。无论如何，对你的配置有一些评论：
关于agent_1.conf：
ckan-channel。关于cygnus_instance_1.conf：
AGENT_NAME必须与agent_1.conf中使用的匹配，即cygnus-ngsi。此外，安装后，您是否开始了Cygnus服务？只是为了确定：）
$ sudo service cygnus start
答案 1 :(得分：2)
编辑2 ：我注意到cygnus_instance_1.conf中的默认命名是cygnusagent，同时在agent_1.conf中使用的是cygnus-ngsi，我已经解决了连接拒绝错误实例文件中的名称。现在我得到了成功的http响应，但是仍然没有在ckan中保存数据，因为我注意到天鹅日志中的一些错误（无论我是通过“service cygnus start”还是其他长启动命令启动cygnus）。
现在，这是成功的回应如下：

这些是agent.conf文件中的通道，源和接收器定义
agent.sources = seqGenSrc
agent.channels = memoryChannel
agent.sinks = loggerSink
agent.sources.seqGenSrc.type = seq
agent.sources.seqGenSrc.channels = memoryChannel
agent.sinks.loggerSink.type = logger
agent.sinks.loggerSink.channel = memoryChannel
agent.channels.memoryChannel.type = memory
agent.channels.memoryChannel.capacity = 100
这就是ckan频道配置
cygnus-ngsi.channels.ckan-channel.type = memory
cygnus-ngsi.channels.ckan-channel.capacity = 1000
cygnus-ngsi.channels.ckan-channel.transactionCapacity = 100
关于ckan方面，我想知道Ckan中是否还有其他程序，而不是创建帐户以持久化ngsi事件。我是否必须手动创建组织和数据集及其数据存储区以接收ngsi事件？或是将fiware服务和服务路径映射到组织和数据集，并在发送ngsi事件时自动创建其数据存储和资源？我只是想确定我是否理解这一点。
现在，您认为我将如何解决这些错误？
