无法启动/启动本地mongo数据库 [英] Unable to start/launch local mongo db

问题描述

我是MongoDB的新手.我目前有一个mongo db(即.bson文件的目录)的转储，并且正在尝试将其导入mongo.

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.

我按照 http:/上的说明安装了mongo /docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/.

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'm currently trying to test starting a local mongo instance by running mongod --dbpath /path/to/my/mongodata (which is an empty directory).

我在stdout中得到以下内容:

I get the following in stdout:

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

这时，它只是挂在那儿，什么也不做.似乎它正在等待本地主机上发生的事情，但是我对mongo的了解还不足以了解正在发生的事情.有帮助吗?

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?

推荐答案

没有问题，您已经启动了服务器，它正在运行并且正在监听端口27017.现在，您可以开始与服务器进行交互，例如，打开一个新的终端选项卡并运行mongo，这将打开mongo的交互式控制台并连接到默认服务器(localhost:27017)

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)

如果要将mongod作为后台进程运行(以返回控制台)，则可以使用-fork 命令选项.这要求您使用某种日志记录.

If you want to run mongod as a background process (to get back the console) you can use --fork command option. This requires you to use some sort of logging.

例如. mongod --dbpath /path/to/my/mongodata --fork --logpath /path/to/my/mongod.log

如果要还原bsonexport，则可能会使用 mongorestore 命令

If you want to restore a bsonexport you will probably use the mongorestore command
