MongoDB cluster configuration

This article demonstrates: (one primary server, one backup server, three quorum servers)

The official recommended replica set has an odd number of members, up to 12 replica set nodes, and a maximum of 7 nodes to participate in the election.

This article demonstrates the use of port-differentiated services based on this machine (the new DB folder under each server is used to store data,mongodb.conf file configuration startup parameters)

The contents of each server configuration file are as follows:

27000 Primary Server

Dbpath=d:\mongodb\server27000\3.2\db

port=27000

replset=datamip/127.0.0.1:27001

There are additional servers under the replica set 27001

27001 backing up the server

Dbpath=d:\mongodb\server27001\3.2\db

port=27001

replset=datamip/127.0.0.1:27000

Primary server

27002 Quorum Server

Dbpath=d:\mongodb\server27002\3.2\db

port=27002

replset=datamip/127.0.0.1:27001

Primary server

27003 Quorum Server

Dbpath=d:\mongodb\server27003\3.2\db

port=27003

replset=datamip/127.0.0.1:27001

Primary server

27004 Quorum Server

Dbpath=d:\mongodb\server27004\3.2\db
