RH033 Red Hat Enterprise Linux Essentials
RH033 is a basic training for Red Hat Enterprise Linux. It mainly introduces some basic operation commands.
Installation --
Since some basic Linux commands and related basic concepts are introduced in the RH 033 course, it is necessary to go to the next course, the first Unit of RH 133, to describe how to install Red hat Enterprise.

But there is no Linux environment, and there is no way to operate commands. Therefore, we will first briefly introduce how to install Red hat Enterprise so that you can operate some Linux commands.
 
Unit 1-Overview The first Unit, which describes some basic LINUX knowledge.
In the first section of UNIX history, we will introduce the history of UNIX development.
First version created in Bell Labs-1969
The first version of the UNIX operating system was developed by Bell Labs in 1969.
AT&T licenses source code for low cost
Because Bell Labs are affiliated with AT&T, the UNIX system, officially launched at a very low price by AT&T
 
The second section of UNIX principles describes the characteristics of UNIX.
Everything is a file
The 1st feature is that everything exists in the form of a shift
Configuration data stored in text
The 2nd feature is that all settings are stored in the text file.
Small, single-purpose programs
3rd features: each program is small and only responsible for a single function
Avoid captive user interfaces
The 4th feature does not require user interfaces
Ability to chain programs together to perform complex tasks
The 5th feature is that you can concatenate many small programs with a single function to perform complex tasks.
 
In the third section of GNU Project/FSF, what is the GNU plan and
FSF
GNU Project started in 1984
The GNU program started in 1984.
Free Software Foundation
Free Software Foundation (FSF)
 
The fourth section of GPL-GNU General Public License describes what is a GPL copyright notice.
Primary license for Open Source software
GPL is a copyright announcement made for open source, that is, open source software. If any software has GPL, it becomes a free open source software.
. Encourages free software
GPL promotes the development of free software
All enhancements and changes to GPL software must also be GPL
All the software released through GPL must also be mounted to GPL to become a free software. That is to say, even if we make great changes to a GPL software, however, we still cannot cancel the GPL software authorization.
 
Linux Origins
. Linus Torvalds
LINUX is developed by Linus Torvalds
. When Linux kernel combined with GNU applications, complete free UNIX-like OS possible
When the core of Linux combined with many GNU software that was then executed on UNIX systems, a UNIX-compatible operating system was completed.
 
Why Linux? In section 6, we will introduce the characteristics of Linux and the reasons for using Linux.
Linux is a UNIX-like OS
1st. Linux has a similar program interface and operation mode as Unix systems, because Linux is a job system developed based on the Unix concept.
Multi-user and multi-tasking
2nd. Linux can be used in environments where multiple workers and workers are working.
Wide hardware support
3rd. Linux supports many new hardware devices
Fully supported
4th. You can get a lot of complete support from the Internet or Red Hat Linux companies.
 
In section 7 of Red Hat Enterprise Linux, we will introduce what Red Hat Enterprise Linux contains.
Custom version of a recent Linux kernel
The first part will provide the latest Linux core
Utilities and applications
The second part will provide some common applications
Installation and configuration software
The third part will provide some software to be installed or set.
Support available
The fourth part will provide all relevant technical support
