Fiware天鹅座构建失败-Java 学习之路

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版本1.7.0和Fiware Cloud 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，虽然我已经完成了我的细节，但它失败了 .

首先安装Apache Flume，如此处所述http://fiware-cygnus.readthedocs.io/en/1.3.0/cygnus-common/installation_and_administration_guide/install_from_sources/index.html

$ 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 Build 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cygnus-ngsi

cd cygnus-ngsi

mvn clean compile exec:exec assembly:single

我在构建它时得到了这些结果：

[INFO] Building cygnus-ngsi 1.7.0_SNAPSHOT

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jar， cygnus-common-1.7.0_SNAPSHOT-jar-with-dependencies.jar 和 cygnus-common-1.7.0.jar 以及包含usr / cygnus / plugins.d / cygnus / libext目录他们实际上我不知道这两个目录中是否存在两个 jar 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

EDIT : 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并成功安装了它们 . 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跑步启动天鹅座

/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

我得到的这些日志仅以侦听8081的jetty服务器结束，如下所示：

当我使用notification.sh测试文件从另一个终端测试天鹅座时，我得到连接拒绝 .

[centos@orcb2 ~]$ ./notification.sh http://localhost:5050/notify

虽然我认为配置文件应该是正确的，但它们如下：

这些是我的agent_1.conf文件源和ckan配置参数：

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？

从这个命令：
```
cp target/cygnus-common-1.1.0-jar-with-dependencies.jar /usr/cygnus/plugins.d/cygnus/libext
```
看来你已经构建了cygnus-common版本1.1.0（是不是？我的意思是， target/ 目录中是否有一个 cygnus-common-1.1.0-jar-with-dependencies.jar 文件？）

尽管如此，在下一个命令中，您已尝试安装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，您是否签出了文档中所述的特定版本？

$ git clone https://github.com/telefonicaid/fiware-cygnus.git $ cd fiware-cygnus $ git checkout <branch>

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 0.0 ...） .

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 .

EDIT 1: [Once installation problems are fixed and the question has been edited regarding a startup problem]

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 ：
- I 'm missing source, channel and sink declarations. In addition, I' m缺少通道配置 . 为简单起见，我猜你有意识地省略了它 .
- 源通道可以限制为 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 .
另外，一旦安装，你开始了Cygnus服务吗？只是要确定：）
```
$ sudo service cygnus start
```

Edit 2 ：i 've solved the connection refused error after i noticed that the default naming in cygnus_instance_1.conf is cygnusagent meanwhile the used one inside the agent_1.conf was cygnus-ngsi and i changed the name in the instance file. and now i get successfull http response , but still the data isn' t持续存在ckan，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了cygnus） .

现在，这是成功的回应如下：

[centos@orcb2 ~]$ ./notification.sh http://localhost:5050/notify

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通道配置

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，我想知道在Ckan中是否还有其他程序，而不是创建帐户来持久化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正确 .

现在，您认为我将如何解决这些错误？
