node.js 在 OSX 上安装和运行 MongoDB

Installing and Running MongoDB on OSX

提问by user2517788

If someone can provide some insights here I would GREATLY appreciate it.

如果有人能在这里提供一些见解，我将不胜感激。

I am new to MongoDB, and (relatively) new to the command line.

我是 MongoDB 的新手，并且（相对）命令行的新手。

I had a express/node.js app running on MongoDB locally successfully, but upon restarting my computer, I attempted to restart the Mongo server and it began giving errors and wouldn't start. Since then, I have re-installed Mongo several times only to find the same error occurring. this is what I am receiving:

我在本地成功地在 MongoDB 上运行了一个 express/node.js 应用程序，但是在重新启动计算机后，我尝试重新启动 Mongo 服务器，它开始出现错误并且无法启动。从那以后，我重新安装了 Mongo 几次，却发现同样的错误发生了。这是我收到的：

privee:mongodb-osx-x86_64-2.4.6 jonlinton$ ./bin/mongo
MongoDB shell version: 2.4.6
connecting to: test
Mon Aug 26 14:48:47.168 Error: couldn't connect to server 127.0.0.1:27017 at     src/mongo/shell/mongo.js:145
exception: connect failed

Am I missing a step? Should I be creating a config file? Some basic guidance would be really helpful. Thanks in advance for any insights.

我错过了一步吗？我应该创建一个配置文件吗？一些基本的指导会非常有帮助。提前感谢您的任何见解。

Assuming you have created the data/db directory under bin after install.

假设您在安装后在 bin 下创建了 data/db 目录。

1. Start a terminal for your mongo server
2. Go to <mongodb-install-directory>/bindirectory

3. Run the command

   ./mongod

4. Start a terminal for your mongo shell

5. Go to <mongodb-install-directory>/bindirectory

6. Run the command (make sure you put the name of the database)

   ./mongo test

1. 为你的 mongo 服务器启动一个终端
2. 进入<mongodb-install-directory>/bin目录

3. 运行命令

   ./mongod

4. 为你的 mongo shell 启动一个终端

5. 进入<mongodb-install-directory>/bin目录

6. 运行命令（确保你输入了数据库的名称）

   ./mongo 测试

更新答案 (9/2/2019)：

Homebrew has removed mongodb formula from its core repository, see this pull request.

Homebrew 已从其核心存储库中删除了 mongodb 公式，请参阅此拉取请求。

The new way to install mongodb using Homebrew is as follows:

使用 Homebrew 安装 mongodb 的新方法如下：

~> brew tap mongodb/brew
~> brew install mongodb-community

After installation you can start the mongodb service by following the caveats:

安装后，您可以按照以下注意事项启动 mongodb 服务：

~> brew info mongodb-community
mongodb/brew/mongodb-community: stable 4.2.0
High-performance, schema-free, document-oriented database
https://www.mongodb.com/
Not installed
From: https://github.com/mongodb/homebrew-brew/blob/master/Formula/mongodb-community.rb
==> Caveats
To have launchd start mongodb/brew/mongodb-community now and restart at login:
  brew services start mongodb/brew/mongodb-community
Or, if you don't want/need a background service you can just run:
  mongod --config /usr/local/etc/mongod.conf

I assume you are using Homebrew. You can see the additional information that you need using brew info $FORMULA

我假设您正在使用 Homebrew。您可以查看需要使用的附加信息brew info $FORMULA

~> brew info mongo                                                           255
mongodb: stable 2.4.6, devel 2.5.1
http://www.mongodb.org/
/usr/local/Cellar/mongodb/2.4.5-x86_64 (20 files, 287M) *
  Built from source
From: https://github.com/mxcl/homebrew/commits/master/Library/Formula/mongodb.rb
==> Caveats
To reload mongodb after an upgrade:
    launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist

Caveats is what you need to follow after installation.

注意事项是安装后需要遵循的内容。

Problem here is you are trying to open a mongo shell without starting a mongo db which is listening to port 127.0.0.1:27017(deafault for mongo db) thats what the error is all about:

这里的问题是你试图打开一个 mongo shell 而不启动一个正在监听端口 127.0.0.1:27017（mongo db 的默认值）的 mongo db，这就是错误的全部内容：

Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:145 exception: connect failed

The easiest solution is to open the terminal and type

最简单的解决方案是打开终端并输入

$ mongod --dbpath ~/data/db

Note: dbpath here is "Users/user" where data/db directories are created

注意：这里的 dbpath 是“Users/user”，其中创建了 data/db 目录

i.e., you need to create directory dataand sub directory dbin your user folder. For e.g say `

即，您需要在您的用户文件夹中创建目录data和子目录db。例如说`

/Users/johnny/data

/用户/约翰尼/数据

After mongo db is up. Open another terminal in new window and type

mongo db 启动后。在新窗口中打开另一个终端并输入

$ mongo

it will open mongo shell with your mongo db connection opened in another terminal.

它将打开 mongo shell，并在另一个终端中打开您的 mongo db 连接。

mongo => mongo-db console
mongodb => mongo-db server

If you're on Mac and looking for a easier way to start/stop your mongo-db server, then MongoDB Preference Paneis something that you should look into. With it, you start/stop your mongo-db instance via UI. Hope it helps!

如果您使用的是 Mac 并且正在寻找一种更简单的方法来启动/停止您的 mongo-db 服务器，那么MongoDB Preference Pane是您应该研究的东西。有了它，您可以通过 UI 启动/停止 mongo-db 实例。希望能帮助到你！

additionally you may want mongo to run on another port, then paste this command on terminal,

此外，您可能希望 mongo 在另一个端口上运行，然后将此命令粘贴到终端上，

mongod --dbpath /data/db/ --port 27018

where 27018is the port we want mongo to run on

其中27018是我们希望 mongo 运行的端口

assumptions

假设

1. mongod exists in your bin i.e /usr/local/bin/for mac ( which would be if you installed with brew), otherwise you'd need to navigate to the path where mongo is installed
2. the folder /data/db/exists

1. mongod 存在于你的 bin 中，即/usr/local/bin/对于 mac（如果你用 brew 安装的话），否则你需要导航到安装 mongo 的路径
2. 文件夹/data/db/存在

Nothing less likely to be outdated that the official docs: https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/

没有什么比官方文档更过时的了：https: //docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/
