Ubuntu Server Management

Automate with Ansible

Leverage the power of Ansible to manage your Ubuntu server infrastructure with playbooks. Install Ansible using sudo apt install ansible and create a playbook.yml file to define your configurations.

Monitor System Performance

Use tools like htop or top to monitor resource usage. htop offers a more detailed, color-coded interface and installable via apt install htop.

Ensure Security with Fail2Ban

Install Fail2Ban (apt install fail2ban) to block brute-force attempts and unauthorized access by scanning logs and blocking IPs repeatedly failing authentication.

Automate Backups

Use tar, rsync, or bacula to back up data. Combine with cron (crontab -e) to automate nightly or weekly backups.

Log Management

Keep track of logs and configure rotation using logrotate to manage log file size and retention. This helps avoid disk space issues and simplifies log analysis.

Use Systemctl for Service Management

Leverage systemctl to manage server services. For example:

• sudo systemctl status ssh - Check status.
• sudo systemctl start ssh - Start a service.
• sudo systemctl stop ssh - Stop a service.
• sudo systemctl enable ssh - Enable on boot.

Integrate with Git

Use git to track and version-control configuration files for your servers. This allows rolling back changes and working with collaborators in a team environment.

Cloud and Container Integration

Use Ubuntu with Docker (sudo apt install docker.io) for managing containerized applications or integrate with Kubernetes (via kubadm or snaps).
