mac下安裝和配置mongodb的步驟詳解

MongoDB是什么

MongoDB是一個基于分布式文件存儲的數據庫。由C++語言編寫。旨在為WEB應用提供可擴展的高性能數據存儲解決方案。

他的特點:高性能、易部署、易使用，存儲數據非常方便。

本文主要給大家介紹了在mac下安裝和配置mongodb的步驟，分享出來供大家參考學習，下面話不多說，來一起看看詳細的介紹：

安裝 mongodb

install 之前，iTerm2 下用 brew 查看已安裝軟件、搜索 mongodb：

brew list
brew search mongodb

安裝 mongodb :

brew install mongodb

此處需要稍等一段時間，成功后會輸出以下即說明安裝成功：

$ brew install mongodb
Updating Homebrew...
==> Downloading https://homebrew.bintray.com/bottles/mongodb-3.4.0.sierra.bottle.1.tar.gz
######################################################################## 100.0%
==> 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

啟動 mongodb

新建一個 iTerm2 窗口，執行 mongod 嘗試啟動 mongodb 但會失敗 exiting：

$ mongod

啟動 mongodb 之前，要先新建一個mongodb默認的數據寫入目錄：

$ mkdir -p /data/db
mkdir: /data/db: Permission denied (沒有權限拒絕訪問)

// sudo 并輸入密碼，重新新建目錄
$ sudo mkdir -p /data/db
Password:

給剛才新建的數據庫目錄賦予權限：

$ sudo chown -R guojc /data

此時，執行 mongod 啟動 mongodb 服務：

$ mongod

mongodb 啟動成功，正等待著被連接。

新建 iTerm2 窗口，執行 mongo，進入 mongodb 命令行模式：

$ mongo
MongoDB shell version v3.4.0
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.0
Welcome to the MongoDB shell.
For interactive help, type "help".

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

繼續在上面的終端輸入 show dbs,會列出系統自帶的2個數據庫：

> show dbs
admin 0.000GB
local 0.000GB
help

小結一下，往后要重新啟動 mongodb 服務、進入 mongodb 命令行的操作：

在一個iTerm2窗口執行：mongod //MongoDB starting........waiting for connections

另一個iTerm2窗口執行：mongo //MongoDB shell

插入數據

首先，在電腦根目錄下安裝 node 的數據驅動庫：

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

新建目錄并編輯text.js文件: s3_mongodb/test.js:

var MongoClient = require('mongodb').MongoClient;
// 連接數據庫
var url_test = 'mongodb://localhost:27017/test'; //數據庫test本不存在，連接時會自動創建

var insertData = function(db){
 // 往test數據庫里新建一個site集合，并插入一條數據
 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，運行 test.js：

node test.js

成功后，來到之前執行過 mongo 的 MongoDB shell 窗口，執行：

> show dbs
admin 0.000GB
local 0.000GB
test 0.000GB
help

繼續執行：選中數據庫test、顯示test中的表，查詢該表的所有數據：

> use test
switched to db test

> show tables
site

> db.site.find()
{ "_id" : ObjectId("593e594ab4727b09349c33a6"), "name" : "guojc", "age" : 99, "hobby" : "movie" }

至此，mongodb的安裝配置與基本啟動就介紹完了。
