Key Functions of a Linux System Administrator

  • System Installation and Configuration

    Example Example

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

    Example 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.

  • Package Management and System Updates

    Example Example

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

    Example 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.

  • User and Group Management

    Example Example

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