Accustomed to how Windows system to know Linux system (a)

First, preface

for the average user, 99% is using the Windows operating system, even if those who use the Linux system are installed on their PCs as Windows systems. Linux system is only used for the server market, it can be said that the server market 80% using Linux system. What are the differences between the two systems?

Roughly speaking:

(1) Linux Faster , better security than Windows
(2) There are many software that can only be run in Windows, and Linux compatible software is under development.
(3) Linux is available on the network side.
(4) Linux is a complex operation, and Windows is relatively simple.

In fine terms:

1, free and charge
In China, Windows and Linux are free, at least for individual users, if the country windows really crackdown on piracy that day, the Linux (or red flag) of the spring! But now Linux is still a long way off, and the road ahead is endless.

2. Software and support
Windows can run most of the software, play 99.999% games, hardware vendors almost 100% of the support. The number of software that can be run directly under Linux is the difference between 1 and 99 compared to Windows, and the people who are currently choosing Linux don't even consider playing games (although there are games that can run under Linux, there are too few. Linux is expecting more hardware vendors to support it.

3. Security
Many people say that Linux security is high, the benevolent see of the beholder. In fact, I think this is not necessary to discuss, when the popularity of Linux to reach the current level of Windows, then the Linux vulnerabilities, viruses, Trojans, backdoor what will definitely springing up, although not dare to say more serious than Windows, but absolutely no less than windows, Plainly because of the current number of users of Linux is too little, too little attention, do the virus of course want their works spread the more widely the better (now the virus is more inclined to obtain illegal benefits, such as account password, etc.), so the virus does not consider the minority of Linux.

There is no attack on the system, no piercing firewall, one thing you can not do, only to show that you level is not enough, here applies a sentence: However persuasive, outsmart.

But for now, if you are extremely disgusted with the viruses, Trojans, and garbage that are emerging under windows, you can really try Linux Oh (individual users do not use Linux).

4. Open source
Open source refers to the external open software source code. If a small programmer writes a software that has his original new technology, he wants to make money and even apply for a patent for it, some groups ask him to open the source code for security reasons (so it can be copied. ), and the best free for everyone to use, surrounded by a group of jealous programmers who make money are also following the booing. The legitimate intellectual property rights and asset rights of an independent business group are exposed to the public encroachment and persecution of political power, which is the open source problem that Microsoft faces in Europe (as for whether Microsoft is a dishonest businessman, this is another matter, and cannot be the reason for vandalism and eating large).

Open source or not, software vendors have the power to choose, whether to purchase the use of this product, this is the user's rights. Actually want to deep, if Linux does not open source, it can still have this market now? Because a lot of people just use Linux for open source.

5. Usage Habits

The same place: desktop, icon, mouse click, there is a difference? In a different way, Windows abandons the DOS character mode and focuses on the graphical interface, making the desktop system more user-friendly. The Linux character mode runs better, and the graphical interface is just a companion item, dispensable. According to their time-to-market, the only thing that Linux can throw away from Windows is to pick it up and carry it back.

6. Technical Support

If you are unfamiliar with or have never been in touch with a computer: Learn Windows--then anyone who has been on the internet can show you twice. Learn linux--hehe, buy books or surf the internet, the depth of the Linux section is good.

If you are familiar with the computer and the Internet, then Windows and Linux is no different, there is a huge amount of information on the Internet for you to check. But looking for a Windows computer is far easier than finding someone who can fix a Linux computer.

Second, install Linux

But as an IT technician, it's no bad thing to learn Linux a little bit. At a minimum, we should also understand how Linux installs, and builds the relevant environment (such as FTP, Web, etc.). Here I will start from how to install Linux to build the basic operation of the relevant environment.

Install Redhat system: I use the redhat7.2 version of the environment here, for the experiment requires me to install two Linux servers (Redhat-server and redhat-client) basic configuration such as:

Install the Start screen directly select the first item, enter continue:

to here on the default language and keyboard, choose Simplified Chinese also OK, but I feel bad, learn Linux on the exercise in English version

Let's go ahead and set the time and area .

Choose Asia, Shanghai, and adjust the time .

re-enter system installation media, network and hostname settings

650) this.width=650; "src=" https://s1.51cto.com/wyfs02/M00/9E/4D/wKioL1mPv7aw2kASAAB65Opj1CA310.jpg "title=" 1.jpg "Width=" "height=" 391 "border=" 0 "hspace=" 0 "vspace=" 0 "style=" width:700px;height:391px; "alt=" Wkiol1mpv7aw2kasaab65opj1ca310.jpg "/>

It is recommended to select the hard drive to install directly (because it is only 20G), it is not recommended to manually allocate space (do not install B). In the actual production environment, we can use RAID to separate a 20G space installation system (enough), the rest of the hard disk space we can be in the system to partition redistribution is not a problem.

This step I recommend only modified under the hostname on the line, the configuration of the NIC we enter the system reconfiguration. Because in a production environment two NICs can be bound (as with the NIC teaming in Windows), increasing the efficiency and security of the network.

then we'll choose the System software installation content

650) this.width=650; "src=" https://s3.51cto.com/wyfs02/M00/9E/4D/wKioL1mPwJiz2jOYAAB5yRiKws0549.jpg "title=" 1.jpg "Width=" "height=" 383 "border=" 0 "hspace=" 0 "vspace=" 0 "style=" width:700px;height:383px; "alt=" Wkiol1mpwjiz2joyaab5yrikws0549.jpg "/>

I recommend direct selection of a graphical system (beginner)

650) this.width=650; "src=" https://s1.51cto.com/wyfs02/M00/9E/5F/wKiom1mPwNrANk9kAAEiTM3xv2U924.jpg "title=" 1.jpg "Width=" "height=" 464 "border=" 0 "hspace=" 0 "vspace=" 0 "style=" width:700px;height:464px; "alt=" Wkiom1mpwnrank9kaaeitm3xv2u924.jpg "/>

Finally click Start Installation

650) this.width=650; "src=" https://s3.51cto.com/wyfs02/M01/9E/4D/wKioL1mPwQ7A-c_VAAB27C6Xvvk620.jpg "title=" 1.jpg "Width=" height= "border=" 0 "hspace=" 0 "vspace=" 0 "style=" width:700px;height:500px; "alt=" wkiol1mpwq7a-c_ Vaab27c6xvvk620.jpg "/>

During the installation process, we are going to complete the root password setting and add a user and password (required)

650) this.width=650; "src=" https://s3.51cto.com/wyfs02/M02/9E/4D/wKioL1mPwVfB9-moAAC78Ys4LOQ571.jpg "title=" 1.jpg "Width=" "height=" 476 "border=" 0 "hspace=" 0 "vspace=" 0 "style=" width:700px;height:476px; "alt=" Wkiol1mpwvfb9-moaac78ys4loq571.jpg "/>

The installation process is basically complete, wait a half hour it installs all the components will prompt to restart, enter the system you can use the new user login can also use the root user login.

Okay, next time I'll show you how to bind a NIC (Load balancer) and build a Yum source.
