MongoDB Installation and Startup

1. Installation

1.1 windows Edition

click https://www.mongodb.com/download-center?jmp=nav#community
Download the msi file on the mongodb official website. Double-click to run it. There is nothing to explain.

1.2 Linux Edition

curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.4.3.tgz    # download
tar -zxvf mongodb-linux-x86_64-3.4.3.tgz                                   # decompression
mv  mongodb-linux-x86_64-3.4.3/ /usr/local/mongodb  

MongoDB executables are located in the bin directory, so they can be added to the PATH path:

export PATH=/usr/local/mongodb/bin:$PATH

1.3 Mac Edition
There are two ways to download the mac version. One is to download the address, just like linux. Here.
The other is through brew installation:

sudo brew install mongodb

If you want to install TLS/SSL support commands as follows:

sudo brew install mongodb --with-openssl

Install the latest development version:

sudo brew install mongodb --devel

2. Start the MongoDB service (take windows as an example)

After installation, the file directory is as follows:

D:\Program Files\MongoDB\Server>tree /a /f
//Folder PATH List
//Volume serial number is 000D-76A0
D:.
\---3.4
    |   GNU-AGPL-3.0
    |   MPL-2
    |   README
    |   THIRD-PARTY-NOTICES
    |
    \---bin
            bsondump.exe
            libeay32.dll
            mongo.exe
            mongod.exe
            mongod.pdb
            mongodump.exe
            mongoexport.exe
            mongofiles.exe
            mongoimport.exe
            mongooplog.exe
            mongoperf.exe
            mongorestore.exe
            mongos.exe
            mongos.pdb
            mongostat.exe
            mongotop.exe
            ssleay32.dll

First, create a folder for storing MongoDB data. I create a folder F: mongodb, then locate it in the bin folder of mongodb and execute the command.

mongod --dbpath=f:\mongodb

The dbpath is used to specify the path to store the data, so the mongodb service starts.

At this time, a new cmd is opened and the shell is opened by entering mongo. In fact, the shell is the client of mongodb and also a compiler of js. The default connection is the "test" database.

D:\Program Files\MongoDB\Server\3.4\bin>mongo
MongoDB shell version v3.4.3
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.3
> db
test
>

3. Access Control

Note that there is a waring when opening the MongoDB service:

2017-04-05T18:45:08.793+0800 I CONTROL  [initandlisten] ** WARNING: Access control is not enabled for the database.
2017-04-05T18:45:08.793+0800 I CONTROL  [initandlisten] **          Read and write access to data and configuration is unrestricted.

This is because the access control (authentication, authorization) is not turned on when the service is started. If this warning can be ignored during the learning phase, the production environment needs to turn on access control:

mongod --auth --dbpath=f:\mongodb

Add users (need to operate without opening access control):

use admin
db.createUser(
...   {
...     user: "test",
...     pwd: "test",
...     roles: [ { role: "__system", db: "admin" } ]
...   }
... )

At this point, use auth to open the service and execute:

db.auth("test","test")

You can continue to operate the database.

4. MongoDb web user interface

MongoDB provides a simple HTTP user interface. If you want to enable this function, you need to specify the parameter - rest at startup.

mongod --dbpath=f:\mongodb --rest

MongoDB's Web interface has 1000 more access ports than the service's.
If your MongoDB runtime port uses the default 27017, you can access the web user interface at port number 28017, i.e. address: http://localhost:28017.
