Learning pathLinux: system administration, LFCS preparation
The contractor who had set up all the IT of a freight forwarder in Abidjan left without handing anything over. The system administrator, from now on, is you. Eight missions follow your first year on this estate: taking over a server nobody has documentation for, opening access for three newcomers without opening the door to everyone, patching a vulnerability on an estate that is half Debian and half RHEL, restoring at 3 am an invoicing system stopped by a full disk, proving to the Internet provider who was right when the customer portal stops answering from the Internet, turning into a reliable service the script whose failures block customs declarations, closing everywhere, before the audit, the account of an employee who left, and finally hardening the server exposed to customers before proving, by rebooting it, that the whole estate gets back up on its own. Each mission is played on a real server, with a terminal in your browser. You diagnose before you touch, you fix without breaking anything, and you leave a written trace that management can read. In practice, the path prepares you for the Linux Foundation's LFCS certification, on its core domains: processes and services, accounts and permissions, packages, disks and LVM, networking and firewalls, systemd and udev, LDAP directories, SELinux and rescuing a system that no longer boots. About twenty-two hours of hands-on practice.
