Linux 天鹅座服务不是作为服务启动的

我已在CentOS 7.0上使用RPM安装，但无法作为服务启动：

[centos@cygnus-mongo ~]$ sudo service cygnus start
Starting cygnus (via systemctl):  Job for cygnus.service failed. See 'systemctl status cygnus.service' and 'journalctl -xn' for details.
                                                           [FAILED]

以下是错误日志：

我的配置如下：

文件cygnus_instance_mongo.conf:

# Who to run cygnus as. Note that you may need to use root if you want
# to run cygnus in a privileged port (<1024)
CYGNUS_USER=cygnus

# Where is the config folder
CONFIG_FOLDER=/usr/cygnus/conf

# Which is the config file
CONFIG_FILE=/usr/cygnus/conf/agent_mongo.conf

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

# Name of the logfile located at /var/log/cygnus. It is important to put the extension '.log' in order to the log rotation works properly
LOGFILE_NAME=/var/log/cygnus/cygnus.log

# Administration port. Must be unique per instance
ADMIN_PORT=8081

# Polling interval (seconds) for the configuration reloading
POLLING_INTERVAL=30

你知道我错过了什么吗

在frb回答后更新 我更改了日志文件路径，出现了一个新错误：

除了

cygnus\u instance\u mongo.conf中的这一行之外，配置中的所有内容都正常：

LOGFILE_NAME=/var/log/cygnus/cygnus.log

它必须是：

LOGFILE_NAME=cygnus.log

即
/var/log/cygnus
中日志文件的名称

此行服务日志中报告了错误：

bash: /var/log/cygnus//var/log/cygnus/cygnus.log: No such file or directory

感谢您的回复，我更新了配置，但出现了一个新错误：由于以前的失败运行，服务的“状态”似乎不一致。尝试添加一个假的
/var/run/cygnus/cygnus_mongo.pid
，看看cygnus服务是否能够删除它（这就是它试图做的，但没有成功，因为文件不存在）并继续运行。实际上，目录“/var/run/cygnus”没有创建，所以我创建了它，然后将其权限更改为777，所以天鹅座的用户可以管理它。谢谢！
