By adminPublished On: 2026年8月7日

A VPS (Virtual Private Server) is one of the most flexible hosting solutions for website owners, developers, and online businesses. Unlike shared hosting, a VPS gives you dedicated resources, full root access, and complete control over your server environment.

Contabo VPS is popular among users who need affordable server resources for:

WordPress websites
Affiliate marketing websites
Business websites
Web applications
Development environments
Docker projects
API services

However, buying a VPS for the first time can be confusing. Many beginners do not know:

Which Contabo VPS plan should they choose?
Which server location is better?
Should they use Ubuntu or another operating system?
How do they connect to the server after purchase?
How do they install a website?

This guide will walk you through the entire process, from creating a Contabo account to deploying your first website.

Data center location
Operating system

Then continue to checkout.

After successful payment, Contabo will create your VPS.

Login information

Keep this information secure because anyone with root access can control your server.

Part 2: First Login, SSH Connection, Linux Setup, and Server Security

After successfully purchasing a Contabo VPS, the next step is connecting to your server and completing the initial configuration.

A newly created VPS is a blank server. Before installing your website or applications, you should:

Connect to the server
Update the operating system
Create basic security protection
Configure firewall rules
Prepare the server environment

This section explains the complete process step by step.

10. Receive Your Contabo VPS Login Information

After your order is completed and the VPS has been created, Contabo will send your server information to your registered email address.

The email usually contains important details such as:

Server IP address
Root username
Initial password
SSH connection information

Example:

Server IP:
123.123.123.123

Username:
root

Password:
your_password

Your IP address is the address used to connect to your VPS.

The root account is the administrator account with full system permissions.

11. Connect to Your Contabo VPS Using SSH

SSH (Secure Shell) is the standard method for managing Linux servers remotely.

You do not need physical access to the server.

You can manage your VPS from your own computer.

Method 1: Connect Using Windows Terminal (Recommended)

Modern Windows systems already include SSH support.

Open:

Start Menu
        ↓
Windows Terminal

or:

Command Prompt

Enter:

ssh root@YOUR_SERVER_IP

Example:

ssh root@123.123.123.123

The first time you connect, you may see:

The authenticity of host cannot be established.
Are you sure you want to continue connecting?

Type:

yes

Press Enter.

Then enter your VPS password.

Note:

When typing the password, Linux does not display characters.

You will see:

Password:

but nothing appears while typing.

This is normal.

Press:

Enter

If the connection is successful, you will see something similar to:

root@server:~#

Congratulations.

You are now controlling your Contabo VPS.

Method 2: Connect Using PuTTY

If you prefer a graphical SSH client, you can use PuTTY.

Download and install PuTTY.

Open PuTTY.

Enter:

Host Name

Your VPS IP address:

123.123.123.123

Port

Default SSH port:

Connection Type

Select:

SSH

Click:

Open

login as:
root

Then enter your password.

12. Basic Linux Commands You Should Know

After connecting to your VPS, you will mainly use command-line instructions.

Here are the most important commands.

Check Server Information

View system information:

uname -a

Check CPU information:

lscpu

Check memory usage:

free -h

Example output:

total
used
available

Check disk usage:

df -h

Navigate Files and Folders

Show current location:

pwd

List files:

ls

Detailed list:

ls -lah

Change directory:

cd folder_name

Example:

cd /var/www

Go back:

cd ..

Manage Files

Create a folder:

mkdir example

Create a file:

touch test.txt

Delete a file:

rm test.txt

Delete a folder:

rm -rf folder_name

Be careful with:

rm -rf

because deleted files usually cannot be recovered.

13. Update Your Contabo VPS System

The first thing after login should always be updating your system.

For Ubuntu:

Run:

apt update

This downloads the latest package information.

Then:

apt upgrade -y

This installs available updates.

You can also run:

apt full-upgrade -y

for a more complete upgrade.

After updating, restart the server if necessary:

reboot

Your SSH connection will close.

Wait about one minute, then reconnect.

14. Create a New Administrator User

Using the root account all the time is not recommended.

A safer method is creating another user.

Create a new user:

adduser username

Example:

adduser admin

Follow the instructions:

Password
Full name
Additional information

Add the user to the sudo group:

usermod -aG sudo admin

Now this user can execute administrator commands.

Example:

sudo apt update

15. Secure SSH Access

SSH is the main entrance to your VPS.

Attackers constantly scan public servers for open SSH ports.

You should improve SSH security.

Disable Root Login

Open SSH configuration:

nano /etc/ssh/sshd_config

Find:

PermitRootLogin yes

Change to:

PermitRootLogin no

Save:

Press:

CTRL + O

Press:

ENTER

Exit:

CTRL + X

Restart SSH service:

systemctl restart ssh

Now direct root login is disabled.

You should connect using your new user:

ssh admin@YOUR_SERVER_IP

16. Change SSH Port (Optional)

The default SSH port is:

Changing it can reduce automated attacks.

Edit:

nano /etc/ssh/sshd_config

Find:

#Port 22

Change:

Port 2222

Restart:

systemctl restart ssh

After changing the port, connect using:

ssh -p 2222 admin@YOUR_SERVER_IP

Important:

Before closing your current SSH session, test the new connection.

Otherwise, you may lock yourself out.

17. Configure Firewall With UFW

Ubuntu includes UFW (Uncomplicated Firewall).

Check status:

ufw status

Enable firewall:

ufw enable

Allow SSH:

ufw allow ssh

or:

ufw allow 22/tcp

If you use a custom SSH port:

Example:

ufw allow 2222/tcp

For websites, allow HTTP and HTTPS:

ufw allow 80/tcp

ufw allow 443/tcp

Check rules:

ufw status

Example:

22/tcp ALLOW
80/tcp ALLOW
443/tcp ALLOW

18. Install Fail2Ban Protection

Fail2Ban helps protect your VPS from brute-force attacks.

Install:

apt install fail2ban -y

Start service:

systemctl enable fail2ban

systemctl start fail2ban

Check status:

systemctl status fail2ban

Fail2Ban monitors suspicious login attempts and blocks abusive IP addresses.

19. Enable Automatic Security Updates

Keeping your system updated is important.

Install:

apt install unattended-upgrades -y

Enable:

dpkg-reconfigure --priority=low unattended-upgrades

This allows Ubuntu to automatically install important security updates.

20. Create Your First VPS Snapshot

Before making major changes, create a backup point.

Contabo provides snapshot functionality inside the Customer Control Panel.

General process:

Log in to Contabo Customer Panel
Select your VPS
