Table of contents for Red Hat Enterprise Linux

1. RHEL is divided into enterprise desktop and enterprise server. The difference should not be big, I haven't used the enterprise desktop specifically, but I heard that the default thing is different. In fact, in the case of Linux, the server version can also be used as a desktop, and the desktop can also be used as a server.

However, the server has a lot of advanced features, which the desktop version does not have, and the desktop version will have some useful desktop applications. Red Hat doesn't have a personal version, and the personal version stopped developing after Redhat Linux 9 years ago and moved to the Fedora project. So now RH only has enterprise linux.

The only difference is the service serial number entered at the time of installation, which corresponds to the service content of the account. The 30-day test has only the most basic services. The highest level of RHEL service is available at any time (most people can't afford that).

3. Again, RHEL sells services, not software. The specific difference is how much it costs and the corresponding service, but if you go to the official website to spend money to buy a service, the cheapest will be 2000+ RMB, right? If you really have the money, you might as well buy a set of Windows 7 Ultimate......

Generally, there will be three versions, the desktop is mainly for personal computers, workstations and server versions, generally for server or scientific research...

The trial version is the same as the one that costs money.

It makes no difference...

Red Hat Enterprise? Are you going to procure for development? Linux is also better for development and servers

Red Hat Enterprise Linux introduces you to a classic enterprise Linux distribution, Red Hat Enterprise Linux (RHEL, Red Hat Enterprise Linux), a famous version with a long history and excellent performance that was once synonymous with Linux. This book provides a detailed overview of the installation, application, and management of RHEL 5 and RHEL 6, as well as how to use RHEL perfectly.

At the beginning of the 21st century, open source software has blossomed everywhere. Traditional industries are all closely integrated with IT technology, and open source applications have penetrated into all aspects of the IT field, from the server to the desktop, from middleware to web applications, from databases to ordinary office applications, open source software can provide a full set of solutions. In 2009, China's 3G was officially put into commercial use, marking that the mobile Internet has officially entered people's lives.

The open-source intelligent terminal operating system represented by Android has surpassed the desktop Linux operating system and has become another field of major success after the Linux server operating system, and Android has become the most important operating system on the Zhina Zhiling Energy terminal. Open source software has become an important cornerstone of building a contemporary information society.

There are a variety of Linux distributions, but for older open source enthusiasts, Red Hat Linux is basically the first major distro they come across. For more than a decade, there has been a variety of publications about Red Hat Linux, but from the perspective of applications, the author of this book has compiled another work of the "Perfect Application Series" book - "Perfect Application of Red Hat Enterprise Linux" based on RHEL 5 and RHEL 6, which are important in the application field. This book is a collection of the author's years of experience in application and operation and maintenance management, and is another masterpiece on Linux system management.

This book has the following key features:

The technology is positioned between RHCE and RHCA.

The RHEL 5 and RHEL 6 versions are fully integrated to achieve the perfect combination of current applications and technological developments.

Based on RHEL, the RHEL application is the mainstay, taking into account the content of the RHCE exam and the appropriate allocation.

The content covers the latest features of RHEL 5 and RHEL 6, all of which are explained with application cases.

This book is a rare learning material for Linux enthusiasts and those who are ready to participate in the Red Hat series certification.

I believe that open source software not only provides users with one more choice, but also provides a broader learning platform and employment opportunities for young people. More choices and use of open source software will change the pattern and development process of China's software industry, and will also make our planet greener!

With the development of information technology in the era of cloud computing, green IT has become the consensus of the society, and as the most active technology in the IT field, there is no shortage of innovation and surprises.

Since its birth in 1993, after nearly two decades of rapid development, Red Hat Linux has become a successful model in the open source community.

Red Hat Enterprise Linux is a comprehensive and in-depth introduction to the most popular RHEL 5 distributions (including CentOS 5 and Scientific Linux 5) and the just-released RHEL 6 (including Scientific Linux 6) applications. From application to management, it comprehensively explains how to use Red Hat Enterprise RHEL and related derivatives perfectly. This book is based on the official Red Hat Certified Engineer RHCE knowledge and is organized according to the learning and cognitive process of beginners, and can be used as a learning and coaching material for Red Hat Enterprise applications and as a RHCE training or tutorial textbook. It can help readers master the practical technologies of Red Hat Enterprise Linux in a short period of time, quickly apply them to production, and apply what they have learned.

I sincerely hope that users and enthusiasts of open source software can use this book as a ladder to make good use of open source software and Linux, apply it to enterprises and serve enterprises, and experience the great value that open source software brings to the current information society.
