So, let’s get started!

📖 How to Run Ubuntu Server

🔧 Installing Ubuntu Server

The first step in running Ubuntu Server is to install the operating system onto your server hardware. This process can vary depending on your hardware and whether you’re installing Ubuntu Server from scratch or upgrading from a previous version. Here are the basic steps to install Ubuntu Server:

Step	Description
Step 1	Download the Ubuntu Server ISO
Step 2	Create bootable media (DVD/USB) with the ISO
Step 3	Boot the server from the bootable media
Step 4	Follow the on-screen instructions to complete the installation

Once installation is complete, you’ll have a fresh instance of Ubuntu Server running on your hardware.

🌐 Configuring Network Settings

Once you’ve installed Ubuntu Server, the next step is to configure your network settings so that your server can communicate with other devices on your network and the internet. Here’s how to configure network settings in Ubuntu Server:

🔌 Setting IP Addresses

The first step in configuring network settings is to set the IP address for your server. This can be done using the netplan utility, which is included with Ubuntu Server. Here’s how to set the IP address:

1. Open the netplan configuration file:

   sudo nano /etc/netplan/50-cloud-init.yaml

2. Find the section for your network interface (usually begins with “eth0”) and add the following lines:

   addresses:- <ip-address>/<subnet-mask>

   Replace <ip-address> and <subnet-mask> with your desired IP address and subnet mask.

3. Save and close the file.
4. Apply the changes:

   sudo netplan apply

Once you’ve set the IP address, you should be able to ping other devices on your network and access the internet.

🔐 Configuring Firewall

Ubuntu Server comes with a powerful firewall called ufw (Uncomplicated Firewall). By default, ufw is set to block all incoming connections, which helps to protect your server from unauthorized access. However, you’ll need to open up ports for certain applications to function properly (such as SSH or HTTP). Here’s how to configure the ufw firewall:

1. Check the status of ufw:

   sudo ufw status

2. Allow incoming connections for a port (e.g. HTTP):

   sudo ufw allow 80/tcp

3. Enable ufw:

   sudo ufw enable

🚪 Configuring SSH

SSH is a secure way to connect to your server remotely and manage it from another device. By default, SSH is enabled on Ubuntu Server, but you’ll need to configure it to allow remote access and set up user accounts. Here’s how to configure SSH:

1. Edit the SSH configuration file:

   sudo nano /etc/ssh/sshd_config

2. Find the following lines and modify them as follows:

   #Port 22#PermitRootLogin without-password

   Change “#Port 22” to the desired port (e.g. 2222) and uncomment it. Change “#PermitRootLogin without-password” to “PermitRootLogin no”.

3. Save and close the file.
4. Restart SSH:

   sudo systemctl restart sshd

Once you’ve configured SSH, you should be able to connect to your server remotely using an SSH client like PuTTY.

🔑 Setting Up User Accounts and Permissions

Now that your server is up and running, it’s time to set up user accounts and permissions so that you can manage your server securely and efficiently. Here’s how to set up user accounts and permissions in Ubuntu Server:

👤 Creating User Accounts

The first step in setting up user accounts is to create a new user. Here’s how to create a new user:

1. Create the new user:

   sudo adduser <username>

   Replace <username> with the desired username.

2. Set a password for the new user:

   sudo passwd <username>

   Replace <username> with the username you just created.

🔓 Granting Permissions

Once you’ve created a new user, you’ll need to grant that user the appropriate permissions to perform tasks on your server. Here’s how to grant permissions:

1. Add the user to the sudo group:

   sudo usermod -aG sudo <username>

   Replace <username> with the username you just created.

2. Log out and then log back in as the new user to test the permissions.
