Unable to start/launch local mongo db
提问by mpuncel
I'm new to MongoDB. I currently have a dump of a mongo db (i.e. directory of .bson files) and am trying to import that into mongo.
我是 MongoDB 的新手。我目前有一个 mongo db 的转储（即 .bson 文件的目录），我正在尝试将其导入 mongo。
I installed mongo as per the instructions on http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/.
我按照http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/上的说明安装了 mongo 。
I'm currently trying to test starting a local mongo instance by running mongod --dbpath /path/to/my/mongodata (which is an empty directory).
我目前正在尝试通过运行 mongod --dbpath /path/to/my/mongodata （这是一个空目录）来测试启动本地 mongo 实例。
I get the following in stdout:
我在标准输出中得到以下信息：
Thu Sep 20 09:46:01 [initandlisten] MongoDB starting : pid=1065 port=27017 dbpath=/path/to/my/mongodata/ 64-bit host=dhcp-18-111-28-92.dyn.mit.edu

At this point, it just hangs there and does nothing. Seems like it's waiting for something to happen on localhost, but I don't know mongo well enough to understand what's going on. Any help?
此时，它只是挂在那里，什么也不做。似乎它正在等待本地主机上发生的事情，但我不太了解 mongo 以了解发生了什么。有什么帮助吗？

There is nothing wrong, you have started the server, it is running and listening on port 27017. Now you can start to interact with the server, for example just open a new terminal tab and run mongo,which will open mongo's interactive console and connects to the default server(localhost:27017)
没有错，您已经启动了服务器，它正在运行并侦听端口27017。现在您可以开始与服务器交互，例如只需打开一个新的终端选项卡并运行mongo，这将打开 mongo 的交互控制台并连接到默认服务器（localhost:27017）
If you want to run mongod as a background process (to get back the console) you can use --forkcommand option. This requires you to use some sort of logging.
如果您想将 mongod 作为后台进程运行（以返回控制台），您可以使用--fork命令选项。这需要您使用某种日志记录。
Eg. mongod --dbpath /path/to/my/mongodata --fork --logpath /path/to/my/mongod.log
例如。 mongod --dbpath /path/to/my/mongodata --fork --logpath /path/to/my/mongod.log
If you want to restore a bsonexport you will probably use the mongorestorecommand
如果你想恢复一个 bsonexport 你可能会使用mongorestore命令

This starts the main MongoDB database process. The waiting for connections message in the console output indicates that the mongod.exe process is running successfully.
这将启动主 MongoDB 数据库进程。控制台输出中的等待连接消息表明 mongod.exe 进程运行成功。
