sudo apt-get install mongodb-org
This command will install the latest stable version of MongoDB, along with its associated tools and libraries.
During the installation process, you may be prompted to confirm the installation and enter your sudo password. Once you have done so, the installation will continue.
After the installation is complete, MongoDB will automatically start running as a service. You can verify this by running the following command:
sudo service mongod status
If everything is working correctly, you should see a message indicating that MongoDB is running.
You can also check the version of MongoDB that has been installed by running:
mongod –version
This will show you the version number and other relevant details.
Optional Configuration Settings
Before we move on to the next section, we should note that there are some optional configuration settings that you may want to consider when installing MongoDB on Ubuntu. These settings can help optimize your installation and make it more secure.
For example, you can use the following command to specify a custom data directory for MongoDB:
sudo mkdir -p /data/db
sudo chown -R $USER:$USER /data/db
This will create a new data directory at /data/db and set the appropriate permissions. You can then modify the MongoDB configuration file to point to this directory.
You may also want to enable authentication for MongoDB, which will require users to provide a username and password in order to access the database. To do this, you can follow the instructions in the next section.
Step 4: Configuring MongoDB on Ubuntu
After installing MongoDB on Ubuntu, the next step is to configure it to optimize performance, ensure data security, and guarantee reliable access control. The following subsections demonstrate how to set up MongoDB on Ubuntu by creating a user account, configuring authentication settings, and tuning relevant system parameters.
Creating a User Account
By default, MongoDB starts without authentication, which means anyone with access to the server can make changes to the database. To secure the system, the first step is to create a user account with administrative privileges. The following steps create a super user with the username “admin” and the password “password”:
- Open the MongoDB shell by typing “mongo” on the command line.
- Switch to the admin database by running “use admin“.
- Create the user account by executing the following command:
db.createUser({ user: "admin", pwd: "password", roles: [ {role: "root", db: "admin"} ] })
Enabling Authentication
With the user account created, the next step is to enable authentication. To do this, edit the MongoDB configuration file located at “/etc/mongodb.conf” and add the following line:
security:
authorization: enabled
Restart the MongoDB service for the changes to take effect by running “sudo service mongodb restart“.
Adjusting Resource Limits
By default, MongoDB may consume large amounts of memory and disk space, which can lead to performance issues. To allocate system resources efficiently, adjust the MongoDB resource limits by editing the “/etc/security/limits.conf” file and adding the following lines:
mongod soft nofile 64000
mongod hard nofile 64000
mongod soft nproc 32000
mongod hard nproc 32000
Save the file and restart the server for the changes to take effect.
Step 5: Starting and Stopping MongoDB Service
Once MongoDB is installed and configured on your Ubuntu system, you may need to start or stop the service for various reasons. Here’s how to do it:
- To start MongoDB on Ubuntu, enter the following command in your terminal:
sudo systemctl start mongod - To stop MongoDB on Ubuntu, enter the following command in your terminal:
sudo systemctl stop mongod
It’s worth noting that stopping the MongoDB service will result in any unsaved data being lost. Therefore, it’s important to properly save and exit any work before stopping the service.
If you want MongoDB to start automatically every time the system boots up, you can enable the service’s auto-start behavior by running the following command:
sudo systemctl enable mongod
Similarly, if you want MongoDB to not start automatically when the system starts up, you can disable the auto-start behavior by running:
sudo systemctl disable mongod
You can also check the status of the MongoDB service on your Ubuntu system by running:
sudo systemctl status mongod
This will display information about whether the service is running, any errors that may have occurred, and more.
