A Beginner's Guide on How to Use a VPS
A Virtual Private Server (VPS) is a popular option for individuals and businesses looking to host websites, run applications, or even host game servers. While VPS may seem intimidating to beginners, it is a valuable tool for anyone looking to host their own website or application.
QuickServers offers KVM-based VPS which is a great solution for those looking to get started. In this guide, we will cover how to access your VPS, common examples of useful commands on a VPS, and how to secure your VPS.
Accessing your VPS
The first step to using your VPS is to access it. There are a few ways you can access your VPS, but one of the most common ways is to use an SSH client like PuTTY. PuTTY is a free, open-source SSH and telnet client that you can use to access your VPS.
Once you have downloaded and installed PuTTY, you will need to enter the IP address of your VPS and connect. Once you are connected, you will be prompted to enter your username and password. Once you have entered your credentials, you will be logged into your VPS.
Common Examples of Useful Commands on a VPS
Once you have accessed your VPS, there are some useful commands that you should know. These commands will help you navigate and use your VPS efficiently.
Sudo: This command is used to run a command with administrative privileges. For example, if you want to install software or make changes to the system, you will need to use this command. To use sudo, simply type "sudo" before the command you want to run.
Apt-get: This command is used to install, update, or remove software packages on your VPS. You can use it to install various packages like Apache, MySQL, and PHP. To use apt-get, type "sudo apt-get" followed by the command you want to run.
Ls: This command is used to list the files and directories in a directory. This command is useful when you want to see what files or directories are in a particular folder. To use ls, simply type "ls" followed by the directory you want to list.
Cd: This command is used to change the current working directory. For example, if you want to move to the "Downloads" folder, you can use the command "cd Downloads" To use cd, simply type "cd" followed by the directory you want to move to.
Chmod: This command is used to change the permissions of a file or directory. You can use it to give yourself or other users permission to read, write, or execute a file. To use chmod, type "chmod" followed by the permission you want to set, followed by the file or directory you want to modify.
Securing Your VPS
When it comes to hosting a website or application on a VPS, security is crucial. Here are some steps you can take to secure your VPS:
Change the default password: When you first access your VPS, the default password will be set to a generic password. The first step in securing your VPS is to change the default password to a strong, unique password.
Update your VPS: Regularly updating your VPS will ensure that you have the latest security patches and updates. To update your VPS, use the command "sudo apt-get update && sudo apt-get upgrade."
Install a firewall: A firewall will help protect your VPS from unauthorized access. You can install a firewall like UFW by using the command "sudo apt-get install ufw" and then configuring it to your needs.
Disable root login: Disabling root login will make it more difficult for attackers.
Managing a VPS
Once you have access to your VPS, there are many tasks you can perform to manage it. Here are some common examples:
Updating your VPS
It's important to keep your VPS up-to-date with the latest security patches and software updates. To update your VPS, log in to the command line and run the following commands:
sudo apt update
sudo apt upgrade
These commands will update your VPS with the latest software patches and updates.
Installing software
One of the benefits of using a VPS is that you can install any software you need. To install software, use the command line to run the appropriate commands for your operating system. For example, to install Apache on Ubuntu, you would run the following command:
sudo apt install apache2
This will install the Apache web server on your VPS.
Managing files
You can manage files on your VPS using the command line. For example, to create a new file, you can use the following command:
touch myfile.txt

nano myfile.txt
This will open the file in the Nano text editor.
Advanced VPS management
Once you are comfortable with managing your VPS using the command line, you may want to explore some more advanced management tasks. Here are some examples:
Monitoring your VPS
You can use monitoring tools like Nagios or Zabbix to monitor your VPS and get alerts if there are any issues. These tools can monitor things like CPU usage, disk space, and network traffic.
Configuring a firewall
To add an extra layer of security to your VPS, you can configure a firewall. This will block unauthorized traffic from accessing your VPS. You can use tools like UFW or iptables to configure your firewall.
Backing up your VPS
It's important to regularly back up your VPS to ensure that you don't lose any data in the event of a disaster. You can use tools like rsync or tar to create backups of your files and folders.
