How to Use ISPConfig 3: A Beginner’s Guide to Managing Your Web Hosting

If you’re looking for a free and powerful hosting control panel, ISPConfig 3 is one of the best options available. It allows you to manage websites, email accounts, databases, DNS records, FTP users, SSL certificates, and more from one web-based dashboard.

Whether you’re hosting a single website or managing multiple servers, this guide will walk you through the basics of how to use ISPConfig 3.

What Is ISPConfig 3?

ISPConfig 3 is a free, open-source hosting control panel for Linux servers. It supports Apache and Nginx web servers, multiple PHP versions, Let’s Encrypt SSL certificates, email hosting, DNS management, FTP accounts, and MySQL or MariaDB databases.

Unlike many commercial hosting control panels, ISPConfig is completely free to use. It is commonly used by developers, server administrators, web hosting companies, and website owners who want more control over their hosting environment.

How to Log In to ISPConfig 3

Open your web browser and enter your ISPConfig login address. It will usually look like one of the following:

https://your-server-ip:8080

Or:

https://panel.yourdomain.com:8080

Enter your ISPConfig username and password, then click Login.

After logging in, you will be taken to the ISPConfig dashboard.

Understanding the ISPConfig Dashboard

The ISPConfig dashboard provides access to the main server and hosting management sections. Depending on your account permissions, you may see the following options:

  • Dashboard
  • Sites
  • Email
  • DNS
  • Monitor
  • Tools
  • System
  • Help

Most website owners will spend the majority of their time in the Sites, Email, and DNS sections.

How to Create a Website in ISPConfig 3

To add a new website:

  1. Click Sites in the main menu.
  2. Click Website.
  3. Click Add New Website.
  4. Select the appropriate client, if applicable.
  5. Enter the domain name.
  6. Select the correct server.
  7. Choose the desired PHP mode and PHP version.
  8. Enable SSL if needed.
  9. Click Save.

ISPConfig will create the website directory and generate the required web server configuration automatically.

How to Upload Website Files

There are several ways to upload website files to an ISPConfig server.

Upload Files Using FTP

To create an FTP account:

  1. Go to Sites.
  2. Click FTP Accounts.
  3. Click Add New FTP User.
  4. Select the website.
  5. Enter a username and password.
  6. Click Save.

You can then connect using an FTP client such as FileZilla.

Upload Files Using SFTP

If SSH access is enabled for your account, you may be able to upload files using SFTP. SFTP is more secure than standard FTP because the connection is encrypted.

Upload Files Using a File Manager

Some ISPConfig installations include a file manager plugin. If available, it allows you to upload and manage website files directly from your browser.

How to Install a Free SSL Certificate

ISPConfig integrates with Let’s Encrypt, allowing you to install free SSL certificates for your websites.

To enable a Let’s Encrypt SSL certificate:

  1. Go to Sites.
  2. Open the website you want to secure.
  3. Check the SSL option.
  4. Check the Let’s Encrypt SSL option.
  5. Click Save.

ISPConfig will request and install the SSL certificate automatically.

Before enabling Let’s Encrypt, make sure the domain is pointing to the correct server IP address.

How to Create an Email Account

ISPConfig can be used to manage email domains, mailboxes, aliases, forwarding addresses, spam filters, and autoresponders.

To create a new email mailbox:

  1. Click Email.
  2. Click Email Mailbox.
  3. Click Add New Mailbox.
  4. Select the email domain.
  5. Enter the mailbox name.
  6. Create a strong password.
  7. Set the mailbox quota.
  8. Click Save.

For example, entering support for the mailbox name on example.com would create:

support@example.com

How to Create a Database

Most content management systems, including WordPress, require a MySQL or MariaDB database.

To create a database in ISPConfig:

  1. Go to Sites.
  2. Click Database Users.
  3. Click Add New User.
  4. Create a database username and strong password.
  5. Click Save.
  6. Return to the Sites section.
  7. Click Databases.
  8. Click Add New Database.
  9. Select the website and database user.
  10. Enter the database name.
  11. Click Save.

You can manage the database using phpMyAdmin if it is installed on the server.

How to Change the PHP Version

ISPConfig can support multiple PHP versions on the same server. This allows one website to use PHP 8.2 while another website uses PHP 8.3 or a different installed version.

To change the PHP version for a website:

  1. Go to Sites.
  2. Open the website.
  3. Locate the PHP settings.
  4. Select the desired PHP mode.
  5. Select the desired PHP version.
  6. Click Save.

Always confirm that your website, plugins, themes, and applications are compatible with the PHP version you select.

Which PHP Mode Should You Use?

ISPConfig may provide several PHP modes depending on the server configuration.

  • PHP-FPM: Recommended for most modern websites because it provides strong performance and efficient resource usage.
  • Fast-CGI: A compatible alternative for some server configurations.
  • PHP-CGI: An older method that is generally slower than PHP-FPM.
  • Disabled: Prevents PHP files from running on the website.

For most WordPress websites, PHP-FPM is the recommended option.

How to Manage DNS Records

If your ISPConfig server is configured to host DNS, you can manage your domain’s DNS records from the DNS section.

Common DNS record types include:

  • A Record: Points a domain or hostname to an IPv4 address.
  • AAAA Record: Points a domain or hostname to an IPv6 address.
  • CNAME Record: Points one hostname to another hostname.
  • MX Record: Controls where email is delivered.
  • TXT Record: Used for verification, SPF, DKIM, DMARC, and other text-based information.

To manage DNS records:

  1. Click DNS.
  2. Open the correct DNS zone.
  3. Add or edit the required record.
  4. Click Save.

DNS changes may take time to fully propagate across the internet.

How to Create an SSH User

If your hosting plan allows SSH access, you may be able to create a shell user.

  1. Go to Sites.
  2. Click Shell Users.
  3. Click Add New Shell User.
  4. Select the website.
  5. Enter the username and password.
  6. Select the appropriate shell and access settings.
  7. Click Save.

SSH access should only be enabled when needed. For improved security, use SSH keys instead of password authentication whenever possible.

How to Monitor Your Server

The Monitor section provides information about your server’s health and services.

Depending on your ISPConfig permissions, you may be able to view:

  • Server load
  • Memory usage
  • Disk usage
  • Running services
  • System logs
  • Mail logs
  • Web server logs
  • Database server status

Regularly reviewing this section can help you identify server problems before they cause extended website downtime.

How to Back Up a Website

ISPConfig includes backup options that may be configured by the server administrator.

Depending on the server setup, backups may include:

  • Website files
  • Databases
  • Email accounts

To view available backups:

  1. Go to Sites.
  2. Open the website.
  3. Click the Backup tab.
  4. Review the available backup files.

Even when ISPConfig backups are enabled, you should maintain at least one additional off-server backup.

ISPConfig Security Best Practices

Follow these basic security recommendations when using ISPConfig:

  • Use strong and unique passwords.
  • Enable SSL certificates on every website.
  • Keep ISPConfig and the Linux operating system updated.
