linux - cygnus 服务未作为服务启动

Question

我已经安装了cygnus在我的 CentOS 7.0 上使用 RPM，但我无法作为服务启动:

[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]

错误日志如下:

Answer 1

除了 cygnus_instance_mongo.conf 中的这一行，配置中的一切都正常:

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

必须是:

LOGFILE_NAME=cygnus.log

即/var/log/cygnus 中的日志文件的名称。

在服务日志的这一行中报告了错误:

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