按照本指南

https://github.com/telefonicaid/fiware-connectors/blob/master/flume/doc/quick_start_guide.md

我试着用

/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

但我得到了这个错误

除了这个错误。我使用服务 cygnus 状态并正确启动。

我把端口改成8085 8084 8083 ...看他读了conf，忽略了这个conf ...

[root@alex alex]# /usr/cygnus/bin/cygnus-flume-ng agent --conf /usr/cygnus/conf -f /usr/cygnus/conf/cygnus_instance_1.conf -n cygnusagent -Dflume.root.logger=INFO,console [-p 8085]

Alejandro，这是 Cygnus 0.7.0 的一个众所周知的错误。本周初，一个新的 0.7.1 版本被上传到 FIWARE repo。无论如何，那个所谓的致命错误（这是一个错误，但不是致命的:)）不会影响 Cygnus 的行为，因为它只影响管理接口（目前只有一种方法可以返回您正在运行的版本）。因此，Cygnus 应该HTTPSource在您为/usr/cygnus/conf/agent_1.conf文件配置的端口中正常工作：

cygnusagent.sources.http-source.port = 5050

在安装新版本之前，我建议您删除以前的版本。我的意思是，不要简单地运行yum install cygnus以更新现有的安装，而是主动地yum remove cygnus然后yum install cygnus. 原因是关于 RPM 部署的另一个错误，该错误也已在 0.7.1 版本中修复。
