Nodejs authorizing the connection to MongoDB

After MongoDB is installed, there is no user connection authorization authentication

Direct input MONGO into interactive mode on the console

Show DBS Use Databasenameshow collections

None of these basic commands are going to be a problem.

############################################

Add user authorization Authentication to MONGODB-----MONGO into interactive mode

Use admin  # to switch to the admin database # displays theDataSet----------------  # View user data in System.users ----db.adduser ('name') ,'pwd'# Add an Administrator account

Then open vi/etc/mongodb.conf.

Find #auth=true and comment out

Then restart the MongoDB database service

Sudo/etc/init.d/mongodb restart

At this point, MongoDB's auth configuration is complete

#################################

Create a Nodejs app

Add a MongoDB Plugin

NPM Install Mongodb-save

Use

var Mongodb=require ('MongoDB'). Mongoclient, URL='Mongo://username:[email protected]:p ort/database?authmechanism=mongodb-cr&authsource=admin',      assert=require ('assert'); Mongodb.connect (Url,function (err,db) {assert. Equal (Err,null); var col=db.collection ('Collection-name');       Col.find ({}). ToArray (function (err,data) {console.log (data); })      })

Where authmechanism is the authorization mechanism this can be viewed through the above Db.system.users.find ()
