天鵝服務沒有啓動的

我已經用我的CentOS 7.0的RPM安裝cygnus服務，但我沒有開始的服務：天鵝服務沒有啓動的

[[email protected] ~]$ sudo service cygnus start

                  [FAILED]

下面是錯誤日誌：

一切都在配置上，除了這條線確定在cygnus_instance_mongo.conf：

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

它必須是：

LOGFILE_NAME=cygnus.log

I.e.日誌文件的名稱在/var/log/cygnus之內。

據報道，這條線的服務日誌的錯誤：

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

感謝您的答覆，我更新了配置，但我有一個新的錯誤：■ – sabrina2020

由於之前失敗的運行似乎「狀態「服務的情況，比方說，不一致。嘗試添加一個假的'/ var/run/cygnus/cygnus_mongo.pid'，讓我們看看Cygnus服務是否能夠刪除它（這是它正在嘗試做的，但沒有成功，因爲該文件不存在），並繼續運行。 – frb

實際上沒有創建目錄「/ var/run/cygnus」，所以我創建了它，然後我將其權限更改爲777，因此cygnus用戶可以管理它。謝謝！ – sabrina2020
