MongoDB是什么

MongoDB是一个基于分布式文件存储的数据库。由C++语言编写。旨在为WEB应用提供可扩展的高性能数据存储解决方案。

他的特点:高性能、易部署、易使用,存储数据非常方便。

本文主要给大家介绍了在mac下安装和配置mongodb的步骤,分享出来供大家参考学习,下面话不多说,来一起看看详细的介绍:

备注:本文相关源码可在文末下载!

安装 mongodb

install 之前,iTerm2 下用 brew 查看已安装软件、搜索 mongodb:

?

2

brew list

brew search mongodb

安装 mongodb :

?

==> Pouring mongodb-3.4.0.sierra.bottle.1.tar.gz

==> Caveats

To have launchd start mongodb now and restart at login:

 brew services start mongodb

Or, if you don't want/need a background service you can just run:

 mongod --config /usr/local/etc/mongod.conf

==> Summary

 /usr/local/Cellar/mongodb/3.4.0: 17 files, 261.4M

启动 mongodb

新建一个 iTerm2 窗口,执行 mongod 尝试启动 mongodb 但会失败 exiting:

$ mkdir -p /data/db

mkdir: /data/db: Permission denied (没有权限拒绝访问)

 

// sudo 并输入密码,重新新建目录

$ sudo mkdir -p /data/db

Password:

给刚才新建的数据库目录赋予权限:

?

$ sudo chown -R guojc /data

此时,执行 mongod 启动 mongodb 服务:

Welcome to the MongoDB shell.

For interactive help, type "help".

Server has startup warnings:

2017-06-12T16:00:48.616+0800 I CONTROL [initandlisten]

2017-06-12T16:00:48.616+0800 I CONTROL [initandlisten] ** WARNING: Access control is not enabled for the database.

继续在上面的终端输入 show dbs,会列出系统自带的2个数据库:

?

> show dbs

admin 0.000GB

local 0.000GB

小结一下,往后要重新启动 mongodb 服务、进入 mongodb 命令行的操作:

在一个iTerm2窗口执行:mongod //MongoDB starting........waiting for connections

另一个iTerm2窗口执行:mongo //MongoDB shell

插入数据

首先,在电脑根目录下安装 node 的数据驱动库:

?

1

2

# guojc @ MacBook-Pro-2 in ~ [16:29:33] C:127

$ cnpm install mongodb

新建目录并编辑text.js文件: s3_mongodb/test.js:

var MongoClient = require('mongodb').MongoClient;

// 连接数据库

var url_test = 'mongodb://localhost:27017/test'; //数据库test本不存在,连接时会自动创建

 

var insertData = function(db){

 // 往test数据库里新建一个site集合,并插入一条数据

 db.collection('site').insertOne({name: 'guojc', age: 99, hobby: 'movie'}, function(err, result){

 console.log('inserted successly');

 console.log(result);

 db.close();

 console.log('close');

 });

}

 

MongoClient.connect(url_test, function(err, db) {

 console.log('Connected successly to server.');

 insertData(db);

});

新建 iTerm2 窗口,运行 test.js:

?

1

node test.js

成功后,来到之前执行过 mongo 的 MongoDB shell 窗口,执行:

?

> show dbs

admin 0.000GB

local 0.000GB

test 0.000GB

继续执行:选中数据库test、显示test中的表,查询该表的所有数据:
