🐧 Supported Linux Distributions

I offer expert-level support for all major Linux distributions, including:

• Community/Server: Ubuntu Server, Debian, CentOS Stream, Rocky Linux, AlmaLinux.

• Specialized/Cloud: Amazon Linux, Fedora, Arch Linux, Alpine Linux, Gentoo.

📖 Getting Started & Common Fixes

Each distribution family has its own "personality." Here is a quick reference for managing them effectively.

1. Package Management (The Big Three)

2. Fixing Common "Broken" States

• Permission Denied: Use ls -l to check ownership. Fix with sudo chown user:group /path or sudo chmod 755 /path.

• Service Won't Start: Check the status immediately: systemctl status service_name. Use journalctl -xe to see the exact error log.

• Disk Space Full: Find the culprit with du -sh /* | sort -h. Clear logs with journalctl --vacuum-time=7d.

💡 Tips for a Successful Server Setup

For a production-ready environment, I recommend following these best practices:

1. 🔑 Disable Root SSH: Always use a standard user with sudo privileges and disable password-based root login in /etc/ssh/sshd_config.

2. 🛡️ Use a Firewall from Day 1: Even if the server is internal, enable ufw or firewalld to limit traffic to strictly necessary ports (22, 80, 443).

3. ⏱️ Synchronize Time: Ensure chrony or ntp is running. Inconsistent system clocks cause major issues with logs, databases, and authentication tokens.

4. 📜 Documentation is King: Keep a "Runbook." If you change a configuration file, comment on why you changed it and when.
