使用dpd-d启动MongoDB失败

Question

我正在尝试启动一个Deployd应用程序。输入dpd后，将收到以下错误消息：

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

在我输入'DEBUG=* dpd‘来调试问题后，我得到了以下信息：

Answer 1

就像上面说的：

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

不管您运行的是mongod的哪个用户都没有写"./data“的权限，不管它在哪里。检查所有权和权限，并考虑使用绝对路径(“/var/ Check /data”)，这样无论现在还是以后，您都不会为自己设置一个相对路径惊喜。

我也有类似的问题。运行DEBUG=* dpd之后，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)

我正在使用Ubuntu 14.04。就我的情况而言，使用sudo dpd解决了这个问题。希望它能对Ubuntu用户有所帮助。
