+# 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)
+     Active: active (running) since Tue 2023-06-27 08:00:00 UTC; 1min 30s ago
+       Docs: https://docs.mongodb.org/manual
+   Main PID: 1234 (mongod)
+      Tasks: 33 (limit: 4915)
+     Memory: 1.2G
+     CGroup: /system.slice/mongod.service
+             └─1234 /usr/bin/mongod --config /etc/mongod.conf
+```
+
+## Securing MongoDB
+
+1. Connect to MongoDB, so that we can create an admin user. Run the following command:
+
+```bash
+mongo
+```
+
+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: Allowing remote connections
+
+1. Open the MongoDB configuration file. Run the following command:
+
+```bash
+sudo nano /etc/mongod.conf
+```
+
+2. Find the `net` section and replace the `bindIp` line with the following:
+
+```bash
+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.
+
+## Finished
+
+You have successfully installed MongoDB on Ubuntu 22.04. You can now connect to MongoDB and start using it.
