1.1 MongoDB安装
在MacOS X系统中，采用Homebrew安装MongoDB。打开终端（Terminal），输入如下：
brew install mongodb
安装完成后，MongoDB所在目录为/usr/local/Cellar/mongodb, 该目录结构如下：
[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] ~$
默认的配置文件为/usr/local/etc/mongod.conf，配置文件内容如下：
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 启动MongoDB服务进程
打开终端，输入如下：
mongod -f /usr/local/etc/mongod.conf
然后，按回车键，就启动了MongoDB服务进程。
1.3 客户端连接MongoDB
重新打开终端，输入：mongo，然后回车，显示如下：
[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] ** WARNING: Access control is not enabled for the database.

则表明连接成功。
1.4 关闭MongoDB服务进程
(1) 服务端直接关闭1.2中的服务进程
(2) 客户端使用管理员命令关闭
-
选择admin数据库
use admin； -
关闭MongoDB服务
db.shutdownServer();
运行示例如下：
> use admin;
switched to db admin
> db.shutdownServer();
server should be down...
