Managing a Linux VPS, SSD VPS, or Linux Private Cloud VPS requires a blend of technical know-how and best practices to ensure optimal performance, security, and reliability. Whether you're managing a traditional VPS, leveraging the speed of an SSD VPS, or utilizing the flexibility of a private cloud VPS, each type of server demands attention to specific details. In this guide, we will explore the do’s and don’ts for these environments, helping you understand the functionalities you should prioritize and the common pitfalls to avoid. Following these guidelines will ensure your server remains secure, performs efficiently, and scales seamlessly as needed.
DO’S:
Ensure Safe SSH/cPanel Access
Before enabling or reconfiguring your firewall or antivirus applications, always verify that you have secure access to SSH and/or cPanel to avoid losing remote access to your server.
Keep Your VPS Updated
Regularly apply system updates using tools like yum, apt, or your OS’s package manager, and ensure your kernel is up-to-date to safeguard against security vulnerabilities
Set Up Strong User Privileges and Control
For daily operations, use non-root user accounts and grant root (sudo) privileges only to trusted individuals to minimize security risks
Configure & Maintain a Server Firewall
Always enable your firewall and restrict access to only the necessary ports and protocols. Retain all default and essential firewall rules/ports; never remove them unless you're certain of the reason for doing so."
Create Email and FTP Accounts via Control Panel
Always create email and FTP accounts through cPanel (or your preferred control panel)
Change the Password
You can update or reset user login passwords as needed to maintain account security
DON'TS
Do Not Remove or Modify Firewall Ports
Altering or removing default-allowed ports and rules can disrupt essential services or lock you out of the server. Only modify firewall settings if you fully understand their purpose and impact
Avoid Randomly Changing the SSH Port
Only change the SSH port if you are experienced and understand the implications. Always document the new port to prevent accidental lockouts from your server
Avoid Manually Editing Core Server Configuration Files via SSH When Using cPanel
Directly modifying configuration files for services like Apache, BIND (DNS), or Exim through SSH can lead to mapping issues and interfere with backup or restore operations. Always use cPanel’s built-in interfaces to manage these settings safely
Do Not Create MySQL Databases or Users via phpMyAdmin When Using cPanel
Always use cPanel’s MySQL tools to create databases and users to ensure correct user-to-database mapping and maintain reliable backup and restore functionality
Avoid Unsupported Customizations on Multi-Location VPS
Making major changes—such as modifying the SSH port—on a multi-location VPS can result in loss of access and may require a full server rebuild, potentially leading to data loss. Proceed only if you fully understand the risks
Don’t Neglect Monitoring, Updates, or Security Best Practices
Failing to regularly monitor your server, apply updates, or follow security best practices significantly increases the risk of system compromise or unexpected downtime
Conclusion:
To ensure optimal performance and security of your Linux Classic VPS, SSD VPS, or Private Cloud VPS, it's important to follow best practices. Always enable SSH or cPanel access before applying firewall or antivirus changes, keep your system updated, and manage users and services through cPanel. Avoid modifying the firewall, network settings, or core configuration files unless you're experienced, as this can break server access or impact backups. Unsupported customizations, especially on multi-location VPS setups, can lead to data loss and require a complete server rebuild. Stick to recommended procedures to keep your VPS stable, secure, and accessible.
