Part 1:
MongoDB Database - Install and access from mongoDB compass on Windows step by step process
Here's a step-by-step guide to installing MongoDB and accessing it using MongoDB Compass on your Windows machine:
MongoDB only supports the 64-bit versions of these platforms. To determine which Ubuntu release your host is running, run the following command on the host's terminal:
cat /etc/lsb-release
Step 1: Install MongoDB Community Edition in Ubuntu
1. Import the Public Key
From a terminal, install gnupg and curl if they are not already available:
sudo apt-get install gnupg curl
To import the MongoDB public GPG key, run the following command:
curl -fsSL https://www.mongodb.org/static/pgp/server-8.0.asc | \
sudo gpg -o /usr/share/keyrings/mongodb-server-8.0.gpg \
--dearmor
2. Create the List File
Create the list file /etc/apt/sources.list.d/mongodb-org-8.0.list for your version of Ubuntu.
Create the list file for Ubuntu 24.04 (Noble):
echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-8.0.gpg ] https://repo.mongodb.org/apt/ubuntu noble/mongodb-org/8.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-8.0.list
3.Reload the Package Database
Issue the following command to reload the local package database:
sudo apt-get update
4. Install MongoDB Community Server
You can install either the latest stable version of MongoDB or a specific version of MongoDB.
To install the latest stable version, issue the following
sudo apt-get install -y mongodb-org
--or--
To install a specific release, you must specify each component package individually along with the version number, as in the following example:
sudo apt-get install -y mongodb-org=8.0.0 mongodb-org-database=8.0.0 mongodb-org-server=8.0.0 mongodb-mongosh mongodb-org-mongos=8.0.0 mongodb-org-tools=8.0.0
Step 2: Run MongoDB Community Edition
1. Start MongoDB.
You can start the mongod process by issuing the following command:
sudo systemctl start mongod
If you receive an error similar to the following when starting mongod:
Failed to start mongod.service: Unit mongod.service not found.
Run the following command first:
sudo systemctl daemon-reload
Then run the start command above again.
2. Verify that MongoDB has started successfully.
sudo systemctl status mongod
You can optionally ensure that MongoDB will start following a system reboot by issuing the following command:
sudo systemctl enable mongod
3. Stop MongoDB.
As needed, you can stop the mongod process by issuing the following command:
sudo systemctl stop mongod
4. Restart MongoDB.
You can restart the mongod process by issuing the following command:
sudo systemctl restart mongod
You can follow the state of the process for errors or important messages by watching the output in the /var/log/mongodb/mongod.log file.
tail -f /var/log/mongodb/mongod.log
Step 3: Install MongoDB Compass
MongoDB Compass is a graphical tool that allows you to visualize and interact with your MongoDB database.
5. Begin using MongoDB.
Start a mongosh session on the same host machine as the mongod. You can run mongosh without any command-line options to connect to a mongod that is running on your localhost with default port 27017.
mongosh
Part 2:
To allow MongoDB connections from a remote server or IP address, you'll need to make some changes to the MongoDB configuration and ensure that your system firewall or cloud security settings permit access. Here's a step-by-step guide on how to do this:
1. Modify MongoDB Configuration (mongod.conf)
MongoDB by default binds to localhost (127.0.0.1), which means it's only accessible locally. To allow remote connections, you'll need to modify the bind IP in the MongoDB configuration file (mongod.conf).
Steps:
Locate the mongod.conf file:
On Linux, it's typically located at /etc/mongod.conf.
Edit the mongod.conf file: Open the file in your preferred text editor.
Look for the following line under the net section:
sudo vi /etc/mongod.conf
bindIp: 127.0.0.1
Modify it to bind to all IP addresses (or specify specific IP addresses). To allow connections from any IP:
bindIp: 0.0.0.0
If you want to restrict access to a specific IP (e.g., 192.168.1.100), set it as follows:
bindIp: 127.0.0.1,192.168.1.100
Save the changes.
2. Open MongoDB Port (Default: 27017) in Firewall
MongoDB typically uses port 27017. You need to ensure this port is open on your server.
For Linux with ufw:
sudo ufw allow 27017
If you are using cloud services (AWS, Azure, etc.), make sure the security group or firewall rule allows access to port 27017 from the remote IPs.
3. Restart MongoDB
After modifying the mongod.conf file, restart the MongoDB service for the changes to take effect.
On Linux:
sudo systemctl restart mongod
4. Configure MongoDB User Authentication (Optional but Recommended)
Allowing remote access makes your MongoDB instance more vulnerable to unauthorized access. It’s highly recommended to set up user authentication to secure your database.
Create an Admin User:
Start the MongoDB shell:
mongosh
Switch to the admin database:
use admin
Create an admin user with username and password:
db.createUser({
user: "admin",
pwd: "admin@123",
roles: [{ role: "userAdminAnyDatabase", db: "admin" }]
});
Enable authorization by adding the following line to mongod.conf:
security:
authorization: enabled
Restart MongoDB for the changes to take effect.
5. Connect to MongoDB Remotely
Now that MongoDB is configured to allow remote connections, you can connect from a remote machine.
Example of a Connection String:
mongosh --host your-server-ip --port 27017 -u "admin" -p "admin@123" --authenticationDatabase "admin"
example:
mongosh --host 127.0.0.1 --port 27017 -u "admin" -p "admin@123" --authenticationDatabase "admin"
Make sure to replace your-server-ip, admin, and admin@123 with your server's IP address, username, and password.
6. Test Remote Connection
Try to connect to MongoDB from a remote machine using the mongosh shell or a MongoDB client like MongoDB Compass.
Example (From Command Line):
mongosh --host <remote-ip> --port 27017
