Installation of Linux CentOS-7.1

Description

First, Version: 7.1 Version:centos-7-x86_64-everything-1503-01.iso download from: http://mirrors.163.com/centos/7/isos/ X86_64/centos-7-x86_64-everything-1503-01.iso

This is the everything version, 7.07GB. Install via USB stick. and to prepare a ultraiso? software.

Second, the purpose of this installation is to turn a computer into a pure Linux system, or a Linux single system, rather than a dual system that coexists with Windows and Linux, or a Linux system in a virtual machine.

Note: Because I am also a beginner, so this installation, the goal is to install, some local configuration is not necessarily the most suitable or optimal, language can choose Chinese place must choose Chinese. As long as Linux works smoothly, it is successful.

???? Hope to succeed, as little as possible to meet the problem.

Finally: Computer Configuration

(1) What is the difference between Centos-xxxx-livecd.ios and Centos-xxxx-bin-dvd.iso? The former is only 700M and the latter has 3.8G. The difference is not only in size, its more essential difference is that Centos-xxxx-livecd.ios can only be loaded into memory to run, can not be installed. Centos-xxx-bin-dvd1.iso can only be installed on the hard drive. (2) What are the Centos-xxx-bin-dvd1.iso,centos-xxx-bin-dvd2.iso? The former is 3.8G and the latter is 500M. The difference is that DVD1 is the installation file for CentOS, and DVD2 is some software for CentOS (which is not needed for simple and practical CentOS). ?

=============================================================================================================== ===================================

The following can finally be formally started. The main reference for this article is: http://blog.sina.com.cn/s/blog_842d5c8a0102vr12.html, but the picture is own. Note In the picture, the L disk is just a normal Windows system disk, only the name is Linux.

1. make USB drive Boot disk

Step: 1, open UltraISO, ' file '--' open '--select mirror location

2. Click ' Start '--' write to HDD image ... '

The software chooses the USB stick automatically, the writing method chooses ' usb-hdd+ ' automatically,

?

At the same time, in the "convenient start" right--"write the new drive dominant record (MBR)"--"usb-hdd+",

Then click "Write" and note that the contents of the USB drive will be emptied.

After that is waiting.

The process of writing the U-disk is automatically formatted as FAT32 format, and after the write is complete, no additional action is required.

Remaining information in the message box:

Turn off the UltraISO.

1. Restart your computer and boot into BIOS setup from USB flash drive

Fortunately, my computer only needs to press F12 at boot time to get the system to boot from the USB stick.

Of course, this does not modify the BIOS, just this time the boot is booting from the USB stick.

To my surprise, this is the first difficulty.

1. Set the start location

Yes, the installer doesn't know where to install it. Must of course be to install from the USB stick, but OK, I do not see which is a U disk.

It is important to note that do not hand the cheap press ENTER to enter!

As you can see, it seems that the second and third are set to boot from the USB stick, which one to choose? All can. Whatever you want is fine.

?

then press TAB or the letter eto explain again, not the carriage return .

Go to a place where you modify a command. This command is where the settings are installed from.

Modify the command to:

Vmlinuz initrd=initrd.img linux dd quiet

Here to thank http://www.augsky.com/599.html this article, or I really do not know which is a U disk

Obviously sdb4 is my U-disk. According to this article, the computer restarts directly with the Restart button on the console.

f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f 12f12f12f12f12f12f12

Wrong attempt: When I first hit the carriage return directly: At this time did not modify the command, of course, there is no installation program, so after some time error: According to the online, this time enter the CD dev/, enter the LS should display some information: Here I did find sdb these things, but I do not see which is a U disk AH. After a 2-hour card here, I finally found the article. Used a Vmlinuz initrd=initrd.img linux dd quiet This order.

?

f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f12f 12f12f12f12f12f12f12

After this reboot, F12 set the USB drive to boot. Then press E or tab to modify the command, and then change the command below to:

Vmlinuz initrd=initrd.img INST.STAGE2=HD:/DEV/SDB4 Quiet

then enter.

Finally came to choose the language interface, and then the graphical setup interface.

But it's not over yet ...

As previously mentioned, choose Chinese

There's a continuation in the lower right corner. Then go to the next page. At this time

"An unknown error has occurred ... "After clicking Quit, the computer restarts automatically.

Fortunately, this mistake was not met by me alone. Because of this, we can see the previous solutions.

or the above article. Said:

I don't know why I can do it again, but I'll do it again. The configuration does not change anything. This time there was no error.

1. The configuration of the graphical interface.

It's not easy to get into the 4th bar.

Start directly after selecting the language.

There is no error in saying this. So here we are:

Localization is all there is to say.

Software installation source also say. The choice of software becomes the second difficulty. In fact, this is not difficult, is a bit of a complicated option.

Here you choose the basic environment, and my understanding is to ask what your computer is for.

After selecting on the left, a bunch of optional packages will appear on the right.

Is the optional package at the minimum installation:

is an optional package for the GNOME desktop:

As I went this far, I found it was not necessary to make the everything version.

Because it is a small white Linux, this place chose the GNOME desktop, the right to select all.

In other words, most packages are not installed.

?

1. Configuring the directory Structure

   Click to open the mounting position

   Here is a third difficulty.

Select the disk on the left, and the following is a manual configuration.

After the point is complete, manually configure the directory. So, here's the problem.

My computer is a 240GB hard drive. However, the hint is only 4MB of free space.

Reason:

See NTFS, that is, the way of cerebral palsy I understand: Because before the installation of Linux, the computer is a win7 system, so the disk file format is NTFS.

Obviously, Linux is not recognized.

Select the first disk. There's a reformat on the right.

After checking the reformat, change the file system on the left to Ext4, set mount point to/boot (wrong on the diagram), and update

Similarly, set/, set/VAR, set/home, set swap. Ah ah ah, there really is a kind of local tyrants feeling, Linux single system Ah, unlike others are two systems can only draw a part of the disk to install LINUX,240GB hard Ah, and finally did not allocate the end:

That's it, it's enough to be allocated.

Obviously you can only accept changes.

1. Lower right corner: start the installation.

With the root password, it's my name.

Set up a normal user Poseidon, not as an administrator, the password is my last name.

Finally wait until this sentence:

After reboot, still is the default to open the USB flash drive, do not know why. You have to unplug the USB flash drive, and then restart the computer with the Restart button on the console.

Smooth access to Gnome

1. Configuration is not over yet

Accept a license message first, and hook it on the line.

Lower right corner

You can log in to the user.

?

Or the choice of Chinese

Then input the source, seems to be let choose Input Method. Not moving. Go straight ahead.

Surprise encounter Ah, incredibly this is configured, I clearly see there are 5 points ah.

Well, yes, that's it.

Finally, thanks again for these 3 articles:
