Linux System Administrator-Linux Server Guidance

Example

Installing Ubuntu Server and configuring network interfaces, hostname, and initial user accounts.

Scenario

A startup needs to set up a new server for its development environment. The Linux System Administrator selects an appropriate Linux distribution, installs the OS, and configures the system to fit the team's requirements.

Example

Using apt-get to install software packages and applying security patches.

Scenario

Ensuring a web server has the latest security updates to prevent vulnerabilities. The administrator schedules regular updates and uses package management tools to keep the software up to date.

Example

Creating user accounts, setting permissions, and managing group memberships for a project team.

Scenario

A project requires specific users to have access to certain directories and files. The administrator sets up user accounts and configures permissions using groups, ensuring secure access control.

Example

Setting up IPTables or Firewalld to secure server ports and configuring SSH for remote administration.

Scenario

A company needs to secure its servers from external threats. The administrator implements firewall rules to limit access to essential services and configures SSH keys for secure remote access.

Example

Implementing rsync and cron jobs to automate backups of critical data.

Scenario

To prevent data loss, the administrator sets up a backup system that regularly copies important files to a remote location, allowing for recovery in case of hardware failure or data corruption.
