默认情况下,在mongodb中连接到特定数据库 [英] Connect to a specific database by default in mongodb
问题描述
我正在Linux机器上运行mongodb.因此,每次我从控制台连接到它(键入mongo
)时,都会得到类似这样的信息:
I am running a mongodb on a linux box. So every time I connect to it from the console (typing mongo
) I get something like this:
MongoDB shell version: 2.4.9
connecting to: test
然后我正在使用myDatabase
(其中myDatabase为99%相同).所以基本上我总是做一些不必要的工作.有没有一种方法可以配置mongo,以便默认情况下它将连接到myDatabase
?
And then I am doing use myDatabase
(where myDatabase is 99% is the same). So basically I always do some unneeded type of work. Is there a way to configure mongo, so that it will connect to myDatabase
by default?
推荐答案
令人惊讶的是,我没有找到与此类似的副本.好的,现在我们有内容了.
Surprised that I don't find a duplicate of this. Okay, now we have content.
在命令行中,只需执行以下操作:
From the command line, just do this:
$ mongo myDatabase
$ mongo myDatabase
文档中实际上涵盖了此内容.向下翻页.没有直接链接,但搜索<db address>
,并且存在相同的示例.
This actually is covered in the documentation, albeit down the page somewhat. No direct link but search for <db address>
and the same example is there.
您当然可以做到:
$ mongo --help
MongoDB shell version: 2.4.9
usage: mongo [options] [db address] [file names (ending in .js)]
db address can be:
foo foo database on local machine
192.169.0.5/foo foo database on 192.168.0.5 machine
192.169.0.5:9999/foo foo database on 192.168.0.5 machine on port 9999
其中显示了用法以及您可以传递的其他选项.
Which shows the usage along with other options you can pass in.
另一件事,不是默认的连接,而是一种快捷方式,您可以在.mongorc.js
文件中执行此操作:
Another thing, not quite a default connect but a shortcut is you can do this in the .mongorc.js
file:
db=db.getSiblingDB("myDatabase")
现在将哪个变量db
分配给该数据库,所以:
Which assigns the variable db
to that database so now:
db.collection.find()
正在对myDatabase
起作用.
