Introducing cPanel/WHM

cPanel and WHM (WebHost Manager) are popular web hosting management tools widely used by hosting providers and web administrators. cPanel provides an easy-to-use interface for managing individual website hosting accounts, allowing users to manage files, databases, email accounts, and other aspects of their websites. It’s particularly well-known for its user-friendly design, making it accessible even to those who may not have extensive technical knowledge.

WHM, on the other hand, is designed for server administrators and hosting resellers. It offers a more comprehensive set of tools for managing the server itself, including account creation, server configurations, and security settings. WHM allows administrators to manage multiple cPanel accounts, making it an essential tool for those managing a large number of websites.

My Project: Setting Up cPanel/WHM on AWS Lightsail

In my current project, I utilized Amazon Lightsail to set up a cPanel/WHM instance on AlmaLinux. Here’s a step-by-step overview of what I did:

Step 1: Creating the AWS Lightsail Instance

The journey began with setting up an AWS Lightsail instance based on AlmaLinux, a popular CentOS alternative. AlmaLinux was chosen for its stability and compatibility with cPanel/WHM, making it an ideal choice for hosting environments.

• Instance Creation: I started by launching a new Lightsail instance, selecting AlmaLinux as the operating system. The simplicity of Lightsail’s interface made it easy to choose the right instance size to match the needs of the project.

Step 2: Assigning a Static IP Address

Next, I moved to the networking section of Lightsail to assign a static IP address to the instance. This step was crucial because it ensures that the instance’s IP remains consistent, which is essential for a reliable hosting environment.

• IP Address Assignment: I created a new static IP and linked it directly to the WHM/cPanel instance. This connection allowed me to manage the server remotely without worrying about IP changes.

Step 3: Powering On and Accessing the Instance

With the IP address configured, I powered on the instance and accessed it via the Lightsail web terminal. This gave me direct access to the server’s command line, where the installation of cPanel/WHM would take place.

• Web Terminal Access: Using the web terminal, I initiated the installation process. The system automatically handled the download and setup of all necessary dependencies, which took some time but completed without a hitch.

Step 4: Completing the WHM Initial Setup

Once the installation was complete, I accessed WHM/cPanel through a web browser. The initial setup wizard guided me through configuring the server’s basic settings.

• WHM Setup: I completed the necessary setup steps within WHM, including linking my cPanel account and activating the 15-day trial. The trial allows up to 30 user accounts, providing ample space to explore and configure various settings.

Step 5: Configuring Basic WebHost Manager Settings

In the WHM interface, I navigated to the “Server Configuration / Basic WebHost Manager Setup” section. Here, I made essential adjustments to ensure the server is tailored to the project’s needs.

• Configuration Adjustments: Key settings were updated to match best practices for security, performance, and user management. Once these changes were made, I saved the configuration to finalize the setup.

Configuring Services in cPanel/WHM and Enhancing Security

After completing the initial setup of cPanel/WHM on my AWS Lightsail instance, the next critical step was to configure the services to optimize performance and security. cPanel/WHM offers a robust service manager that allows administrators to enable or disable services based on the specific needs of their server environment.

Service Manager Configuration

In the Service Manager section of WHM, I carefully reviewed the list of services running on the server. Some services, which were not necessary for my current setup, were promptly disabled. Disabling unused services not only conserves system resources but also reduces potential attack vectors.

For instance, I disabled services related to email management, as they weren’t required for this project. Conversely, I ensured that essential services, such as Apache (for web hosting) and MySQL (for database management), were enabled and configured to start automatically when the server boots.

This fine-tuning of services helped streamline the server’s operations, ensuring that only the necessary components were active, thus contributing to a more secure and efficient hosting environment.

Enhancing Security with Security Manager

Once the service configurations were complete, I moved on to the Security Manager in WHM to bolster the server’s defenses. The Security Manager in WHM is a comprehensive suite of tools designed to protect the server from various threats, including unauthorized access, malware, and brute-force attacks.

Here are some of the key actions I took within the Security Manager:

• ConfigServer Security & Firewall (CSF): I configured CSF, a popular firewall for cPanel servers, to monitor and filter incoming and outgoing traffic based on predefined security rules. This added an extra layer of protection against unauthorized access and potential attacks.
• Activating Jail Apache: Within the Tweak Settings area of WHM, I enabled the Jail Apache option. This feature further enhances security by confining each user’s Apache processes to their own file system, preventing them from accessing other users' data.
• Installed ImunifyAV: I added ImunifyAV, a powerful antivirus and malware scanner designed specifically for Linux servers. This tool continuously monitors the server for malicious files and vulnerabilities, providing an extra layer of security to protect hosted websites from potential threats.
• SSH Configuration: While SSH direct root logins are permitted on this server for administrative convenience, I’ve ensured that other security measures, such as key-based authentication and strict password policies, are in place. This approach balances ease of access with the need for a secure environment.
• ModSecurity: I enabled ModSecurity, an open-source web application firewall (WAF), to protect the server from common web-based attacks such as SQL injection and cross-site scripting (XSS). I also reviewed the default rule set and adjusted it to meet the specific needs of my server environment.
• KernelCare’s Free Symlink Protection: As part of the security configuration process, I also added KernelCare’s Free Symlink Protection. This free patch set is specifically designed to protect the system from symlink attacks, which are a common method used by malicious users to exploit symbolic links and gain unauthorized access to files and directories.
• cPHulk Brute Force Protection: To guard against brute-force attacks, I activated cPHulk, a powerful tool within WHM that blocks IP addresses that repeatedly fail login attempts. I configured the sensitivity of this tool to ensure a balanced approach between security and user accessibility.
• Secure Shell (SSH) Access: For added security, I reviewed and restricted SSH access by disabling root logins and enforcing the use of key-based authentication. This minimizes the risk of unauthorized access via SSH, which is often targeted in server attacks.
• MySQL Configuration: Initially, the MySQL service was configured to listen on all network interfaces, which is indicated by bind-address=*. To enhance security, I updated the MySQL configuration by setting bind-address=127.0.0.1 in the /etc/my.cnf file. This change ensures that MySQL only accepts connections from the local machine, reducing the risk of unauthorized access. Additionally, for external access control, I recommended using the server’s firewall to restrict access to TCP port 3306.
• System Updates and Reboot: After applying updates to the system’s core libraries and services, it was essential to reboot the server. Rebooting ensures that all updates take effect, improving the overall stability and security of the system.

Installing ConfigServer Security & Firewall

As part of securing the cPanel/WHM environment on my AWS Lightsail instance, I installed and configured ConfigServer Security & Firewall (CSF), a robust firewall solution specifically designed for cPanel servers. CSF plays a crucial role in enhancing server security by providing a comprehensive firewall management system.

Downloading and Installing CSF

To get started with CSF, I used wget to download the installation package directly to the server. Here’s a quick overview of the process:

1. Downloading CSF: I used the wget command to download the latest version of CSF from the official repository. This command fetched the installation package efficiently:

wget https://download.configserver.com/csf.tgz        

2. Extracting the Package: After downloading, I extracted the package using tar:

tar -xzf csf.tgz        

3. Installing CSF: With the package extracted, I navigated to the CSF directory and ran the installation script:

cd csf
sudo sh install.sh        

Configuring CSF

Once CSF was installed, I configured it to enhance the server’s security because as default it is in test mode:

- Traffic Filtering: CSF filters both incoming and outgoing traffic based on predefined security rules, helping to prevent unauthorized access and mitigate potential threats.

- Intrusion Detection: The firewall includes intrusion detection capabilities that can identify and block suspicious activities in real-time, further protecting the server from attacks.

- Customizable Security Rules: CSF allows for fine-tuning of security rules, enabling me to customize the firewall settings according to the specific needs of the server environment.

By implementing CSF, I significantly enhanced the overall security posture of the server, ensuring that it is well-protected against a wide range of potential threats.

Creating User Accounts

In addition to configuring services and enhancing security, I also set up user accounts within cPanel/WHM. This is a crucial step for managing access and ensuring that each user has the appropriate level of permissions.

• Creating User Accounts: I created user accounts in cPanel for clients and stakeholders who will be managing their own websites. Each account was set up with specific permissions tailored to their needs, such as access to file management, email settings, and domain management. This segregation of user roles helps maintain security and organization within the server.
• Account Management: By setting up these accounts, I facilitated a structured approach to server management, allowing users to handle their web hosting needs independently while maintaining overall control through WHM.

Installing cPAddons Site Software

One of the features available in cPanel/WHM is the ability to install cPAddons Site Software. This tool allows you to easily add and manage site software applications on your server, enhancing its functionality and providing additional services for your hosted sites.

To access this feature, navigate to:

Home → cPanel → Install cPAddons Site Software

Important Note: Please be aware that the cPAddons Site Software interface has been deprecated as of cPanel & WHM version 104 and is planned for removal in future versions. For up-to-date information and alternatives, refer to the cPanel Deprecation Plan documentation.

This deprecation means that while the feature is still available in some versions, it is no longer being actively developed or supported, and future updates may not include it. It’s advisable to explore alternative methods or tools for site software management as you plan for future server maintenance and upgrades.
