Chapter III Linux installation of the operating system

Because the author has always been using CentOS, this installation is also based on the CentOS installation. Insert the CD into the CD drive and set the BIOS drive to boot. Enter the CD's Welcome screen.

　　

There are two options, you can press enter directly, or you can enter Linux text in the current interface press ENTER. The former is a graphical installation, you can move the mouse, the latter is in plain text form. It is recommended for beginners to install the former. After the direct return, the interface appears:

This step is to prompt you whether you want to verify the disc, the purpose is to see if the CD installation package is complete or has been changed, in general, if it is a regular disc does not need to do this step, because too much time. Next is:

This step has nothing to explain, direct point "Next"

Here is the choice to install the system language, the author used to use Chinese, of course, you can also choose Chinese (Simplified), choose good after the "Next"

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

Here you will be prompted, the following partition, will initialize the disk, the data on the disk will be lost, asked if you want to initialize the device and erase the data on the disk. Because it is an empty disk, select "Yes"

At this point, it's the partition. A total of four options are available for you to choose from.

First, all partitions are removed on the selected disk and then partitioned by default;

Second, remove all Linux partitions on the selected disk (if the disk has a partition in Windows format and will not be removed), then partition by default;

Third, only the idle portion is used on the selected disk, and partitioned by default;

The fourth type, user-defined.

Here we choose the fourth kind. And then "Next"

Next the partition, the partition is very flexible, but in general according to this rule (this is the server on this point, if you are a virtual machine, see the following section):

1. /boot partition 100M

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

3. /Partition to 20G

4. Spare space for/data

Description: The/boot partition is required for the system to boot, similar to the Windows directory in Windows C disk, the file in this partition is not big, only need 100M enough. Swap partitions are swap partitions, and when memory is not enough, the system will use this part of the space as memory. /partition, which is actually a root directory, will be described in a later chapter. Now do not understand and no matter, just know there is such a thing can. /data This partition is what we customize, that is, the partition that specifically puts the data.

If you are installing a virtual machine and you have only 8G of disk space, then I recommend that you partition it like this:

1/boot 100M

2 swap memory twice times

3/All remaining space

After the partition is finished, click "Next"

Can be checked in front of use a boot loader password, this option is to add a password to the boot loader, in order to prevent someone from entering the single-user mode through the CD-ROM to modify the root password.

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

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 through DHCP, you can also point manually custom a hostname, such as mail.example.com. If neither of these methods is configured, then Linux will give you a universal hostname, that is, localhost.localdomain the remaining few will not be configured, the default is left blank.

Next, choose the time zone, here of course choose our time zone asia/chongqing if there is no Chongqing then choose Asia/shanghai.

Continue to the next

Define a root password here and proceed to the next step.

Here we choose the package to install, I am accustomed to custom installation, need to point the following "Customize now" then next

"Desktop environments" look at the right side, the gnome front of the hook removed, this is actually the graphical interface of the installation package, if you do not remove this tick, will install the graphical interface.

"Applications" in addition to editors in front of the hook removed, the others do not

"Development" is all going to be hooked up.

"Servers" and all of the following items do not tick any, then next

After you click Next, the system starts to install.

After a meeting, it will appear.

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