How To Setup Local MongoDB

How To Setup Local MongoDB

Download

• Go to the site: https://www.mongodb.com/try/download/community
• Download the community server version

Navigate to Bin Folder

• Open File Explorer
• Navigate to the folder that the MongoDB was downloaded:

for example "C:\Program Files\MongoDB\Server\5.0\bin"

Open Command Prompt

• Open a command prompt (open in administration mode if MongoDB is in "C:\Program Files")
• Change directory to the folder that the MongoDB was downloaded:

for example cd "C:\Program Files\MongoDB\Server\5.0\bin"

Stopping the default DB Instance

• Open task manager
• Go to the processes tab
• Find the processes called "MongoDB Database Server"
• Click on the process and End Task

Start Local DB Instance

• In the command prompt enter the following command
  mongod.exe --replSet rs0 --dbpath="C:\Program Files\MongoDB\Server\5.0\data"
  (the --dbpath flag is optional, this is where the database files will be saved)
• Keep this command prompt running in the background

Create Replica Set

• Using File Explorer, open the application called: "mongo.exe"
• A new command window should open
• type the following command:
  rs.initiate()
• A message should output stating "ok": 1, and the command should start with "rs0: Primary>"

> rs.initiate()
{
    "info2" : "no configuration specified. Using a default configuration for the set",
    "me" : "tutorialkart:27017",
    "ok" : 1
}
rs0: Primary > |

Now MongoDB is running locally using replica sets.

Future Use

• To use replica sets in the future, you only need to run the command:
  mongod.exe --replSet rs0 --dbpath="C:\Program Files\MongoDB\Server\5.0\data"
  (the --dbpath flag is optional, this is where the database files will be saved)

Tips

• Create a .bat file in the bin folder and enter the line:
  mongod.exe --replSet rs0 --dbpath="C:\Program Files\MongoDB\Server\5.0\data"
• Save the .bat file.
• To run a MongoDB instance, just run that .bat file
