无法启动Fiware Cygnus作为服务

Question

我在centOS 7上使用RPM安装了fiware cygnus，但无法启动它作为服务。我得到了以下错误：

[[email protected] cygnus]# sudo service cygnus start 
Starting cygnus (via systemctl): Job for cygnus.service failed. See 'systemctl status cygnus.service' and 'journalctl -xn' for details. 
                  [ÉCHOUÉ] 
    [[email protected] cygnus]# systemctl status cygnus.service -l 
    cygnus.service - SYSV: cygnus 
     Loaded: loaded (/etc/rc.d/init.d/cygnus) 
     Active: failed (Result: exit-code) since ven. 2015-07-31 19:11:10 CEST; 2s ago

juil. 31 19:11:10 localhost systemd[1]: Unit cygnus.service entered failed state. 

不知道该用什么作为配置文件中的代理名称：cygnus_instance_1.conf因为它没有reconize代理名称

# Name of the agent. The name of the agent is not trivial, since it is the base for the Fluleters 
# naming conventions, e.g. it appears in .sources.http-source.channels=... 
AGENT_NAME= mongo-channel 

这里是我的完整配置文件： cygnus_instance_1.conf

最新通报@frb响应后： 我更新了我的cygnus_instance_1.conf @frb响应，但unfortuantly因为我得到了以下错误：

展望上面的错误，我看到它无法找到文件“/var/run/cygnus/cygnus_1.pid”，所以我创建了一个空文件来绕过这个错误，但我得到了一个新问题：cygnus_instance_1.conf必须在

[[email protected] ~]# sudo systemctl start cygnus.service

Answer 1

根据您的agent_1.conf配置，AGENT_NAME是cygnusagent。即：

AGENT_NAME = cygnusagent 

此外，CYGNUS_USER应cygnus，因为这是在安装软件时的RPM创建用户。
