How to Work with a VPS Server?

In today's world of information technology, many projects require stable and flexible server solutions. A Virtual Private Server (VPS) provides a unique opportunity to obtain dedicated resources without investing in physical equipment. But how do you work with a VPS server and maximize its capabilities? This article will explain how to use a VPS server, how to connect to a VPS server, and what advantages it offers.

What Is a VPS?

A VPS (Virtual Private Server) is a virtual server that runs on a physical server and is divided into several independent virtual machines. Each machine has its own resources, operating system, and settings, allowing users to fully control and configure the environment according to their needs.

Who Is a VPS Suitable For?

A VPS server is ideal for:

• Developers and webmasters who need personalized server environment settings.
• Businesses that require high performance and security for their applications and websites.
• Startups and projects plan to scale and avoid the limitations of shared hosting.
• Users who need administrator access to the server to install specific software.

How to Use a VPS Server?

Using a VPS involves several steps:

1. Renting a VPS Server

• Choose a hosting provider that offers the resources and services you need.
• Determine the required specifications: memory amount, CPU cores, and disk space.

2. Configuring the Operating System

• Choose an OS (most commonly Linux distributions: Ubuntu, CentOS, Debian, or Windows Server).
• Configure the system after installation: update packages set up localization.

3. Installing Necessary Services

• Web servers (Apache, Nginx) for hosting websites.
• Databases (MySQL, PostgreSQL) for storing information.
• Mail services if you plan to work with email.

4. Managing the Server

• Use SSH access to manage via the command line.
• Install a control panel (e.g., cPanel, Plesk) to simplify administration.

5. Ensuring Security

• Create new users and set passwords.
• Configure the firewall and access rules.
• Regularly update the system and install patches.

How to Connect to a VPS Server?

SSH (Secure Shell)

With Secure Shell, you can gain remote access to your VPS, performing actions on the server as if you were working directly on it. SSH is a protocol that provides secure remote access to other computers over unsecured networks. Thanks to encrypted connections, user authentication, and data integrity protection, SSH allows you to securely manage remote servers, transfer files, and execute commands. Below is a connection guide:

For Windows

1. Install the program PuTTY.
2. Open PuTTY.
3. In the field "Host Name (or IP address)", enter the IP address of your VPS server.
4. Ensure that port 22 and protocol SSH are selected.
5. Click "Open".
6. In the window that appears, enter your username and password.

For Linux and macOS

1. Use the built-in terminal; open it.
2. Enter the command: ssh username@server_IP_address (e.g., ssh user@192.168.1.1).
3. On the first connection, a warning about the host's authenticity may appear; type yes and press Enter.
4. Enter your password when prompted.

SFTP (SSH File Transfer Protocol)

SSH File Transfer Protocol is a protocol for secure file transfer that operates over SSH. It provides an encrypted channel for data exchange between the client and server, ensuring file protection and information confidentiality. SFTP not only allows uploading and downloading files but also supports operations like creating directories, changing access rights, and deleting data.

For Windows

1. Install the program FileZilla or WinSCP.
2. Open the program.
3. Enter the following details:
   • Host: IP address of your VPS server.
   • Username and password: your server credentials.
   • Port: 22.
   • Protocol: select SFTP.
4. Click "Quick connect" or "Login".

For Linux and macOS

1. Use the built-in terminal; open it.
2. Enter the command: sftp username@server_IP_address.
3. Enter your password when prompted.
4. Use SFTP commands to manage files.

RDP (Remote Desktop Protocol)

Remote Desktop Protocol is a proprietary protocol developed by Microsoft that allows users to remotely connect to a computer or server with a graphical interface. RDP provides a convenient way to work with remote machines, giving access to the full functionality of the operating system, including running applications, managing files, and configuring the system.

1. Ensure that the Remote Desktop service is installed and configured on the server.
2. Open the program "Remote Desktop Connection" by pressing Win + R or typing mstsc and pressing Enter.
3. In the field "Computer", enter the IP address of your VPS server.
4. Click "Connect".
5. Enter your username and password when prompted.
6. After a successful connection, you will see the remote server's desktop.

FAQ

What is better to choose, Windows or Linux for a VPS?

If you need applications specific to Windows or a graphical interface, choose Windows. If you plan to run a web server and value flexibility, Linux is more suitable. Choosing the right OS will ensure the server works efficiently for your specific tasks.

How to ensure server security?

Your server may be vulnerable to attacks and unauthorized access. Configure a firewall (Firewall for Windows or UFW for Linux), use strong passwords, regularly update the system, and limit SSH access. This will enhance server security, reduce the risk of hacking, and protect your data.

What does it mean to configure localization?

Incorrect language and time settings can complicate server management. Set the system language and time zone according to your region. Proper localization will simplify working with the server and ensure the accuracy of logs and schedules.
