[MongoDB] The Access control of mongodb, mongodbaccess

In this blog we mainly talk about the access control including limitation of ip, setting listen port and usage of username and password. in the official document, mongodb server start without the argument, so once the connection was created, the remote client cocould do everything. but in the productive environment it's advisable to take security into consideration and to enhance the security protection. for the sake of lowing the potential risk, the above measures cocould be taken to deal with these problems.
First, Binding IP address to access MongoDB.
Mongodb cocould put restriction on the ip address thought argument 'Bind _ ip' when being started. For example, now we only limit ip address [192.168.55.165] to access the server.

Secondly, use the certain port

Thirdly, add user and password

The company is preparing to use the mongodb database. I have checked a lot of information about mongodb usage problems and the mongodb cost problems.

Mongodb is free of charge

I am new to mongodb. How can I use java to perform multi-condition queries on mongodb databases?

Package maven. demo. test;

Import java. util. ArrayList;
Import java. util. List;

Import com. mongodb. BasicDBObject;
Import com. mongodb. DB;
Import com. mongodb. DBCollection;
Import com. mongodb. DBObject;
Import com. mongodb. Mongo;
Import com. mongodb. QueryOperators;

Public class MongoDB {
Private static void print (String str ){
System. out. println (str );
}
Public static void main (String [] args ){
Try {
// Create a connection
Mongo m = new Mongo ("127.0.0.1", 27017 );
// Obtain the database
DB db = m. getDB ("test ");
// Obtain all databases
// List <String> colls = m. getDatabaseNames ();
// For (String str: colls ){
// System. out. println (str );
//}

//// Obtain all the sets (tables)
// For (String collection: db. getCollectionNames ()){
// System. out. println (collection );
//}

// Delete a database
// M. dropDatabase ("sun ");

// Obtain the sun table
DBCollection coll = db. getCollection ("things ");

// View the index of a table
// For (DBObject index: coll. getIndexInfo ()){
// System. out. println (index );
//}

// DBObject myDoc = coll. findOne ();
// System. out. println (myDoc );

// Add
// BasicDBObject doc = new BasicDBObject ();
// Doc. put ("name", "sunshan ");
// Doc. put ("sex", "male ");
// Doc. put ("age", 22 );
// Coll. insert (doc); ...... the remaining full text>
