Question

我正在尝试启动Deployd应用程序。输入dpd-d后，出现以下错误消息：

starting deployd v0.6.11...
Failed to start MongoDB

输入＆＃39; DEBUG = * dpd＆＃39;为了调试这个问题，我得到了以下内容：

Answer 1

就像它在这里说的那样：

2014-04-24T23:00:07.795-0400 [initandlisten] couldn't open ./data/local.ns errno:13 Permission denied
2014-04-24T23:00:07.795-0400 [initandlisten] error couldn't open file ./data/local.ns terminating

无论用户运行mongod是什么，因为没有权限写入“./data”，无论在哪里。检查所有权和权限并考虑使用绝对路径（“/ var / wherever / data”），这样就不会为自己设置相对路径的惊喜，无论是现在还是以后。

我有类似的问题。运行DEBUG=* dpd后，我得到：

Failed to start MongoDB (Make sure 'mongod' are in your $PATH or use dpd --mongod option. Ref: http://docs.deployd.com/docs/basics/cli.html)

我使用的是Ubuntu 14.04。对于我的情况，使用sudo dpd解决了这个问题。希望它对Ubuntu用户有所帮助。

无法使用dpd-d启动MongoDB
