# Installing MongoDB
|
|
|
|
This guide provides instructions on how to install MongoDB on Ubuntu 22.04. Installing Mongo is a fairly simple process.
|
|
|
|
## Updating the System
|
|
|
|
- We will start by updating the apt package list. Run the following command:
|
|
|
|
```bash
|
|
sudo apt update
|
|
```
|
|
|
|
This will update the apt package list so that we ensure that the latest versions of packages are available.
|
|
|
|
- Next, we will upgrade the packages. Run the following command:
|
|
|
|
```bash
|
|
sudo apt upgrade
|
|
```
|
|
|
|
This will upgrade the packages to the latest versions.
|
|
|
|
## Installing required packages
|
|
|
|
- Now, we will install some packages that are required. Run the following command:
|
|
|
|
```bash
|
|
sudo apt install gnupg2 wget
|
|
```
|
|
|
|
## Installing MongoDB
|
|
|
|
1. Import the MongoDB GPG key. Run the following command:
|
|
|
|
```bash
|
|
wget -nc https://www.mongodb.org/static/pgp/server-6.0.asc
|
|
cat server-6.0.asc | gpg --dearmor | sudo tee /etc/apt/keyrings/mongodb.gpg >/dev/null
|
|
```
|
|
|
|
These commands will download the GPG key and import it, which will allow us to verify the packages.
|
|
|
|
2. Add MongoDB to the apt sources list. Run the following command:
|
|
|
|
```bash
|
|
sudo sh -c 'echo "deb [ arch=amd64,arm64 signed-by=/etc/apt/keyrings/mongodb.gpg] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/6.0 multiverse" >> /etc/apt/sources.list.d/mongo.list'
|
|
```
|
|
|
|
This command will add the MongoDB apt repository to the sources list.
|
|
|
|
3. Update the apt package list. Run the following command:
|
|
|
|
```bash
|
|
sudo apt update
|
|
```
|
|
|
|
This will update the apt package list so that we ensure that the latest versions of packages are available.
|
|
|
|
4. Install MongoDB. Run the following command:
|
|
|
|
```bash
|
|
sudo apt install mongodb-org
|
|
```
|
|
|
|
This will install the latest stable version of MongoDB.
|
|
|
|
5. Start MongoDB. Run the following command:
|
|
|
|
```bash
|
|
sudo systemctl start mongod
|
|
```
|
|
|
|
6. Enable MongoDB so that it will automatically start on system boot. Run the following command:
|
|
|
|
```bash
|
|
sudo systemctl enable mongod
|
|
```
|
|
|
|
7. Verify that MongoDB is running. Run the following command:
|
|
|
|
```bash
|
|
sudo systemctl status mongod
|
|
```
|
|
|
|
You should see something like this:
|
|
|
|
```bash
|
|
● mongod.service - MongoDB Database Server
|
|
Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled)
|
|

|
|
CGroup: /system.slice/mongod.service
|
|
└─1234 /usr/bin/mongod --config /etc/mongod.conf
|
|
```
|
|
|
|
## Finished
|
|
|
|
You have successfully installed MongoDB on Ubuntu 22.04. For user creation and securing MongoDB, please see the next sections.
|
|
|
|
## Optional: Securing MongoDB
|
|
|
|
1. Connect to MongoDB, so that we can create an admin user. Run the following command:
|
|
|
|
```bash
|
|
mongosh
|
|
```
|
|
|
|
2. Switch to the `admin` database. Run the following command:
|
|
|
|
```bash
|
|
use admin
|
|
```
|
|
|
|
3. Create an admin user. Run the following command:
|
|
|
|
```bash
|
|
db.createUser(
|
|
{
|
|
user: "admin",
|
|
pwd: "SET ME", # Generate a random string with: openssl rand -base64 32 | cut -c1-32
|
|
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
|
|
}
|
|
)
|
|
```
|
|
|
|
4. Exit the mongo shell. Run the following command:
|
|
|
|
```bash
|
|
exit
|
|
```
|
|
|
|
5. Now, we need to secure enable authentication, this will secure the server and prevent unauthorized access. Run the following command:
|
|
|
|
```bash
|
|
sudo nano /etc/mongod.conf
|
|
```
|
|
|
|
6. Find the `security` section. We need to uncomment it, and add the following line below it, it should look like this:
|
|
|
|
```bash
|
|
security:
|
|
authorization: enabled
|
|
```
|
|
|
|
7. Save the file and exit the editor. You can do this by pressing `CTRL + X`, then `Y`, then `ENTER`.
|
|
|
|
## Optional: Adding a user / database
|
|
|
|
1. Connect to MongoDB, so that we can create a user. Run the following command:
|
|
|
|
```bash
|
|
mongosh -u admin -p --authenticationDatabase admin
|
|
```
|
|
|
|
This will ask you for the password that you set earlier in the Securing MongoDB section, or if you didn't secure MongoDB, run the following command:
|
|
|
|
```bash
|
|
mongosh
|
|
```
|
|
|
|
2. Switch to the database that you want to add a user to eg: `forum`. Run the following command:
|
|
|
|
```bash
|
|
use forum
|
|
```
|
|
|
|
3. Create a user. Make sure to change the `db` to match the database used above. Run the following command:
|
|
|
|
```bash
|
|
db.createUser(
|
|
{
|
|
user: "forum",
|
|
pwd: "SET ME", # Generate a random string with: openssl rand -base64 32 | cut -c1-32
|
|
roles: [ { role: "readWrite", db: "forum" } ]
|
|
}
|
|
)
|
|
```
|
|
|
|
4. Exit the mongo shell. Run the following command:
|
|
|
|
```bash
|
|
exit
|
|
```
|
|
|
|
You have now created a user for the `forum` database. You can repeat this process for any other databases that you want to create users for.
|
|
|
|
## Optional: Allowing remote connections
|
|
|
|
1. Open the MongoDB configuration file. Run the following command:
|
|
|
|
```bash
|
|
sudo nano /etc/mongod.conf
|
|
```
|
|
|
|
2. Find the `net` section, we need to update the `bindIp` value, it should look like this:
|
|
|
|
```bash
|
|
net:
|
|
port: 27017
|
|
bindIp: 0.0.0.0
|
|
```
|
|
|
|
3. Save the file and exit the editor. You can do this by pressing `CTRL + X`, then `Y`, then `ENTER`.
|
|
|
|
4. Restart MongoDB. Run the following command:
|
|
|
|
```bash
|
|
sudo systemctl restart mongod
|
|
```
|
|
|
|
You should now be able to connect to MongoDB from a remote machine.
