javascript - 使用 dpd -d 启动 MongoDB 失败

Question

我正在尝试启动已部署的应用程序。键入 dpd-d 后，我收到以下错误消息:

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

在我输入“DEBUG=* dpd”来调试问题后，我得到以下消息:

就像这里说的:

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

无论你运行 mongod 的用户是什么，都没有写入“./data”的权限，无论它在哪里。检查所有权和权限并考虑使用绝对路径(“/var/wherever/data”)，这样您就不会为自己设置相对路径惊喜，无论是现在还是以后。
