Because the author has been using CentOS, so this installation system is also based on CentOS installation. Insert the CD into the CD drive and set the BIOS CD drive to boot. Enter the welcome interface for the disc.

There are two options, you can press enter directly, or you can enter the Linux text press return under the current interface. The former is installed under the graphics, you can move the mouse, the latter is pure text form. It is recommended that beginners use the former installation. After the direct return, appear the interface:

This step is to indicate whether you want to verify the disc, the purpose is to see if the installation package is complete or have been modified, in general, if it is a regular disc does not need to do this step, because too time-consuming. Next is:

This step has nothing to say, just click "Next."

This is the choice to install the system in the language, the author is accustomed to using Chinese, of course, you can also choose Chinese (Simplified), select a good point "Next"

Here is the choice of the appropriate keyboard, we usually use the English keyboard, so there is no move, the default can be, direct "Next"

Here you will be prompted, the following partitions, initialization of the disk, the data on the disk will be lost, ask you whether you want to initialize the device and erase the data on the disk. Because it is an empty disk, select "Yes"

By this step, it's time to partition. There are a total of four ways you can choose

First, remove all partitions from the selected disk, and then partition them by default;

The second is to remove all Linux partitions on the selected disk (if there is a Windows-formatted partition on the disk, it will not be removed), and then by default, partition;

The third is to use only the idle part on the selected disk and partition by default;

The fourth type, user customization.

Here we choose the fourth species. Then "Next"

The next section, the zoning is very flexible, but in general follow this rule (this is the server on this point, if you are a virtual machine, please see the following section):

/boot Partition 100M

Swap partition memory twice times, if greater than or equal to 4G, then just give 4G

/Partition to 20G

Spare space for/data

Description:/boot partition is the file required for system startup, similar to Windows directory in Windows C disk, the file in this section is not large enough and only needs 100M. Swap partitions are swap partitions, and when there is not enough memory, the system will use this part of the space as memory. /partition, is actually a root directory, in later chapters will be introduced. It does not matter now, as long as you know there is such a thing can. /data This partition is our custom, is the partition that specially puts the data.

If you have a virtual machine installed, and you only have 8G of disk space, then I recommend that you partition:

1/boot 100M

2 swap memory twice times

3/All remaining space

When the partition is finished, click Next.

You can tick in front of the use a boot loader password, this option is to add a password to the boot loader, in order to prevent someone from the CD into Single-user mode to modify the root password.

The following options can also be ticked, the author has never used this function, if you are interested, you can study. And then the next step

This step is to configure the network card information, you can now customize the IP card, and configure the host name, by default is obtained by DHCP, you can also point manually custom a host name, such as mail.example.com. If these two ways are not configured, then Linux will give you a universal host name, that is, localhost.localdomain the remaining few are not configured, the default blank.

Next, select the time zone, where we will certainly choose our time zone asia/chongqing if there is no Chongqing then choose Asia/shanghai.

Continue to the next step

Here you define a root password and continue to the next step

Here we choose to install the package, the author is accustomed to customizing the installation, need to point below "Customize Now" then next

"Desktop environments" look to the right, the gnome before the check out, this is actually a graphical interface installation package, if not remove this hook, will install the graphical interface.

"Applications" except the editors in front of the hook removed, the other do not

All the "Development" must be hooked up.

"Servers" and all of the following items are not checked, and the next step

When you click Next, the system starts to install.

After the meeting, there will be

At this point, the Linux system has been installed. Next click the "Reboot" reboot and go to the Linux system to see.
