我使用this guide在Ubuntu 14.04上安装了Cygnus，当我继续启动cygnus（正确填充）时：
nohup APACHE_FLUME_HOME/bin/cygnus-flume-ng agent --conf APACHE_FLUME_HOME/conf -f APACHE_FLUME_HOME/conf/cygnus.conf -n cygnusagent -Dflume.root.logger=INFO,LOGFILE [-p <mgmt-if-port>] [-t <polling-interval>] &
我得到了这个输出：
Warning: JAVA_HOME is not set!

答案 0 :(得分：1)
正如您在此日志中看到的那样：
2015-05-20 18:51:59,589 (conf-file-poller-0) [WARN - org.apache.flume.conf.FlumeConfiguration$AgentConfiguration.addProperty(FlumeConfiguration.java:1046)] Invalid property specified: channel
由于属性channel无效，因此未配置频道。而不是那样，你必须使用channels：
cygnusagent.channels = mysql-channel
请考虑使用Cygnus template创建您的配置（还有一个section in the README）。
答案 1 :(得分：0)
日志的一个问题是：
2015-05-20 18：51：59,652（Thread-1）[FATAL - com.telefonica.iot.cygnus.http.JettyServer.run（JettyServer.java:62）]运行管理界面时发生致命错误。详细信息=已在使用的地址
这是由于在一次运行天鹅座的试验中产生的垃圾处理过程。解决了这个过程。
还在其他响应中建议的更改清除所有警告。
