🧠 Mastering the Command Line

To kickstart your journey, we have compiled this essential "Distro-Specific" command guide.

1. Package Management Across the Landscape

2. Fixing Common Linux Issues

• Issue: "No Space Left on Device"

  • Fix: Run du -sh /* to find the culprit. Check /var/log for bloated logs or run sudo apt clean to clear cache.

• Issue: SSH Connection Refused

  • Fix: Verify the service status: sudo systemctl status ssh. Check the firewall: sudo ufw status or sudo firewall-cmd --list-all.

• Issue: High Load Average

  • Fix: Use top or htop (highly recommended) to identify the process consuming CPU/RAM. Use iotop to check for disk-heavy processes.

💡 Tips for a Successful Server Setup

1. Always Use Key-Based Authentication: Disable password logins for SSH immediately. It stops 99% of brute-force attacks.

2. Logical Volume Management (LVM): Always use LVM for partitioning. It allows you to resize partitions on the fly without reformatting.

3. Document Everything: Create a "Golden Image" or an Ansible playbook. If the server dies, you should be able to recreate it in minutes, not hours.

4. Monitor Early: Don't wait for a crash. Install Prometheus/Grafana or Netdata the moment the OS is live.
