Performing basic configurations on a newly installed Ubuntu server is crucial for system security and stability. In this guide, you will find steps for static IP, hostname, hosts file, updates, and installing essential packages.

🔄 1. System Updates

First, make sure your system is up to date:

sudo apt update && sudo apt full-upgrade -y && sudo apt autoremove -y

🌐 2. Set Hostname

Set the server hostname with the following command:

sudo hostnamectl set-hostname panel.arifakyuz.com

📁 3. Edit Hosts File

Map the hostname to its IP address:

sudo nano /etc/hosts

Add or edit the following lines:

127.0.0.1       localhost
10.128.196.95   panel.arifakyuz.com panel

📡 4. Configure Static IP Address

Use ip a command to find your network interface name. Then edit the netplan configuration:

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

Example configuration:

network:
  version: 2
  ethernets:
    ens18:  # ← Check your interface name!
      dhcp4: no
      addresses:
        - 10.128.196.250/24
      gateway4: 10.128.196.1
      nameservers:
        addresses:
          - 8.8.8.8

Apply the configuration:

sudo netplan apply

📦 5. Install Basic Packages

Install necessary basic tools:

sudo apt install net-tools

sudo apt install -y curl wget sudo

♻️ 6. Restart Services

After configuration, restart web services:

sudo systemctl restart apache2
sudo systemctl restart nginx

✅ Conclusion

Your Ubuntu server is now running with a static IP, a defined hostname, and essential software installed. This setup will make your server more stable and easier to manage.
