Question

我正在使用AWS与EC2和EBS。系统确实工作并添加了一个已安装的EBS驱动器。然后我将驱动器映射到/ data并添加/ data / db，然后更改新数据文件夹的mongod.conf。现在mongo将无法启动。当我从ubuntu命令行输入mongo时，我得到以下内容。

2015-04-14T10:49:21.292+0000 W NETWORK  Failed to connect to
   127.0.0.1:27017, reason: errno:111 Connection refused
2015-04-14T10:49:21.294+0000 E QUERY    Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed
at connect (src/mongo/shell/mongo.js:179:14)
at (connect):1:6 at src/mongo/shell/mongo.js:179
exception: connect failed

如果我使用mongod尝试运行某些东西，它会挂起如下：

我尝试删除mongod.lock文件，它只是返回。日志似乎根本没有新条目。在更改conf之前系统确实工作，这是添加/ data和新EBS的唯一变化。我有最新版本的mongo和ubuntu。

Answer 1

好的，我用

解决了这个问题

sudo service mongod start

然后我使用了命令

mongo

这打开了数据库的接口。

我找到了一些关于启动mongo an的引用到我的消息。

无法连接到Mongo数据库
