Course NT-LA2 Linux Administration, part 2
The course provides knowledge on the basic issues of administering Linux systems from elementary user commands to complex system maintenance issues. It can be conditionally divided into two parts. First, using Linux/Unix systems, and second, administering Linux systems. In the first part, the basic tools of the system administrator are studied: the command interpreter, the vi editor, programs for working with files, processes, character streams, and a number of others. In the second, the system itself, its main elements, their purpose and use. This course, or a similar one for FreeBSD, in combination with NT-LNet course, forms the basis for the rest of the Open Systems Learning Center courses.
After completing this course, students will be able to:
- How is the operating system established
- What is the purpose of Linux OS component parts and how to use them for solving the specific problems
- In what way the functionality of the system is provided
- Basic file management operations
- Implement permissions control
- Perform file system mounts
- Create and edit files using the vi text editor
- Effective use of the command shell
- Create and customize command shell scripts
- Use Linux utilities
- Optimally allocate system performance
- Perform process management
- Implement specific operations with files and file system
- Automate the tasks of system administration
- Install OS Linux
- Recovery system
- Set up and configure the system
- Install software from of RPM-packages and archives source program
- Manage system boot process, configure a loader and run levels
- Implement OS Kernel configuration and compilation
- Configure system for specified hardware
- Perform configuration of system services: schedule launch, running processes on a schedule, logging system
