1.1 MongoDB安裝
在MacOS X系統中，采用Homebrew安裝MongoDB。打開終端（Terminal），輸入如下：
brew install mongodb
安裝完成后，MongoDB所在目錄為/usr/local/Cellar/mongodb, 該目錄結構如下：
[xinhuan@MacBook-Pro] ~$ tree /usr/local/Cellar/mongodb/
/usr/local/Cellar/mongodb/
└── 3.4.7
├── INSTALL_RECEIPT.json
├── README
├── bin
│ ├── bsondump
│ ├── mongo
│ ├── mongod
│ ├── mongodump
│ ├── mongoexport
│ ├── mongofiles
│ ├── mongoimport
│ ├── mongooplog
│ ├── mongoperf
│ ├── mongoreplay
│ ├── mongorestore
│ ├── mongos
│ ├── mongostat
│ └── mongotop
└── homebrew.mxcl.mongodb.plist
2 directories, 17 files
[xinhuan@MacBook-Pro] ~$
默認的配置文件為/usr/local/etc/mongod.conf，配置文件內容如下：
systemLog:
destination: file
path: /usr/local/var/log/mongodb/mongo.log
logAppend: true
storage:
dbPath: /usr/local/var/mongodb
net:
bindIp: 127.0.0.1
1.2 啟動MongoDB服務進程
打開終端，輸入如下：
mongod -f /usr/local/etc/mongod.conf
然后，按回車鍵，就啟動了MongoDB服務進程。
1.3 客戶端連接MongoDB
重新打開終端，輸入：mongo，然后回車，顯示如下：
[xinhuan@MacBook-Pro] ~$ mongo
MongoDB shell version v3.4.7
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.7
Server has startup warnings:
2017-09-05T00:59:42.419+0800 I CONTROL [initandlisten]
2017-09-05T00:59:42.419+0800 I CONTROL [initandlisten] ** WARNING: Access control is not enabled for the database.
2017-09-05T00:59:42.419+0800 I CONTROL [initandlisten] ** Read and write access to data and configuration is unrestricted.
2017-09-05T00:59:42.419+0800 I CONTROL [initandlisten]

>
則表明連接成功。
1.4 關閉MongoDB服務進程
(1) 服務端直接關閉1.2中的服務進程
(2) 客戶端使用管理員命令關閉
-
選擇admin數據庫
use admin； -
關閉MongoDB服務
db.shutdownServer();
運行示例如下：
> use admin;
switched to db admin
> db.shutdownServer();
server should be down...
