Fiware 为什么天鹅座不继续跑？,fiware,fiware-cygnus,Fiware,Fiware Cygnus,按照上面的说明，我只更改了2个配置文件第一个是cygnus_instance_1.conf（实际上我刚刚重命名了示例文件）：我甚至成功地完成了测试，并获得了以下输出： Tests run: 72, Failures: 0, Errors: 0, Skipped: 0 [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] -----

按照上面的说明，我只更改了2个配置文件

第一个是cygnus_instance_1.conf（实际上我刚刚重命名了示例文件）：

我甚至成功地完成了测试，并获得了以下输出：

Tests run: 72, Failures: 0, Errors: 0, Skipped: 0

[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 1:28.380s
[INFO] Finished at: Tue Dec 08 15:25:16 CET 2015
[INFO] Final Memory: 43M/112M
[INFO] ------------------------------------------------------------------------

测试成功是因为我正确配置了java和maven：

[root@localhost fiware-cygnus]# echo $JAVA_HOME
/usr/java/jdk1.8.0_65
[root@localhost fiware-cygnus]# java -version
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)
[root@localhost fiware-cygnus]# mvn -version
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 14:51:28+0100)
Maven home: /usr/local/maven
Java version: 1.8.0_65, vendor: Oracle Corporation
Java home: /usr/java/jdk1.8.0_65/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-504.12.2.el6.x86_64", arch: "amd64", family: "unix"

所以当我点击

服务天鹅座开始时一切都很好

，因为我得到：

Starting Cygnus 1...                                       [  OK  ]

但2秒钟后，当我点击

服务天鹅座状态时，我得到：
cygnus-flume-ng dead but pid file exists

顺便说一下，Context broker工作得很好，但它只是不知道我输入的订阅不会有任何进展
这是天鹅座的日志（没有时间戳，所以我将发布第一个和最后一个）：

如果您不熟悉FIWARE技术，请忽略此问题
问题与日志写入有关。默认情况下，日志写入conf/log4j.properties
指定的路径，即/logs/flume.log
。然而，这样的路径应该被放置在conf/cygnys_instance_1.conf
的配置覆盖，即/var/log/cygnus/cygnus.log
。我仍然不知道为什么（可能有bug），但是您的Cygnus正在覆盖日志文件名（Cygnus.log
），而不是路径（/log
）。结果是Cygnus尝试在/log/Cygnus.log
中写入，我猜
是只允许写入根用户的路径（Cygnus作为Cygnus
用户运行）。解决方法是编辑log4j.properties
并配置：
flume.log.dir=/var/log/cygnus

我遇到了同样的错误，并通过更改cygnus\u instance\uu.conf
中的配置文件修复了它：
CONFIG_FILE=/usr/cygnus/conf/agent_<id>.conf

CONFIG_FILE=/usr/cygnus/conf/agent_u.conf
能否显示conf/log4j.properties
的内容？@frb I已按要求添加。我应该强调的是，我没有接触该文件，并将其保留为默认状态，因为在安装过程中没有另外指定该文件…我不应该被修改。。。但是日志文件有问题。conf`中所有文件的权限是什么？哪些是
/var/log/cygnus`？@frb嗨，请查看我的上一次编辑2，在那里我做了ls-lI编辑了我的问题，其中包括我的最新日志。请检查一下，因为你的解决方案还没有解决我的问题。天鹅座现在在5秒后死亡…好吧，我想出来了，我刚刚将agent_1.conf重命名为agent.conf，它正在运行。我现在的问题是，我是否应该将cygnus_instance_1.conf重命名为cygnus_instance.conf？您不应该这样做。在agent_uu.conf
和cygnus\u instance_uu.conf
中都需要id（1）。这就是Cygnus的几种配置同时运行的方式（只是告诉您，我认为这不是您可能需要的功能）。
