VPS Server Setup, Optimization & Linux Hardening
Provision, optimize, and secure your Linux VPS (Ubuntu/AlmaLinux) from command line. Disable root logins, set up firewalls, Fail2ban, and Nginx.
Common Symptoms I Resolve
Are you experiencing any of the following issues?
- New empty VPS on DigitalOcean or AWS that needs setup from command line
- Unauthorized login attempts or high numbers of failed SSH connections in logs
- Slow page response times due to poorly configured web server limits
- Server vulnerability scans showing open ports or outdated system packages
- Dreaded out-of-memory crashes due to missing Swap space configuration
What is Included in This Service
Full comprehensive fixes and audits for your system:
- OS installation and package upgrades (Ubuntu Server, Debian, AlmaLinux)
- Disabling root passwords login and configuring secure SSH Key authentication
- Setting up UFW or Firewalld to close unneeded public ports
- Installing and tuning Fail2ban to ban aggressive brute-force attackers
- Optimizing Nginx/Apache configs, PHP-FPM execution limits, and MySQL databases
- Configuring virtual Swap memory and automated cronjobs for safety updates
My Step-by-Step Fix Workflow
A transparent and secure process to get your issues resolved quickly.
Server Provisioning
I access the server command line via SSH, update core system repositories, and set up a non-root administrative user with sudo privileges.
Port & Firewall Locking
I restrict SSH to specific keys or custom ports, and configure firewall rules to block everything except HTTP, HTTPS, and SSH.
Brute-force Protection
I install Fail2ban filters that monitor login logs and automatically ban IP addresses demonstrating suspicious behavior.
Performance Tuning
I adjust resource allocations for Nginx, PHP, and MySQL depending on the VPS's RAM and CPU core counts.
Frequently Asked Questions
Have questions about my technical services? Find quick answers below.
Yes, I will need initial root access to implement hardening rules. I recommend setting a temporary root password, which you can change immediately after my work is complete, or sharing SSH keys.
Fail2ban is an intrusion prevention software framework. It scans log files (e.g., SSH, auth logs) and bans IP addresses that show malicious signs like too many password failures, reducing system CPU strain.
Yes. I can configure cronjobs that compress web directories and databases daily/weekly, sending them to external storage like AWS S3 or back up to the VPS hosting panel backups system.
