CentOS hard installation and CentOS installation hardware requirements

php editor Xinyi introduces you to CentOS hard installation and CentOS installation hardware requirements. CentOS is a Linux-based operating system that is widely used in enterprise servers and personal computers. Hard installation of CentOS refers to installing the CentOS system directly on the computer's hard disk. This installation method is more stable and has better performance than virtual machine installation. Before performing hard installation, you need to understand the hardware requirements of CentOS to ensure that your computer meets the installation conditions. Next, we will introduce the hardware requirements and hard installation steps of CentOS in detail to help you successfully complete the installation process.

CentOS Hard Installation

CentOS can be installed through hard disk installation or network installation. Hard disk installation is to install CentOS installation media (usually ISO image file) to the hard disk, and then boot into the installation interface for installation. For network installation, download the installation media through a network connection and install it.

The hard disk installation steps are as follows:

1. Download the ISO image file of CentOS and write it to a bootable media (such as a U disk or CD).

2. Insert the bootable media into the computer and restart the computer.

3. Enter the computer's BIOS setup interface and set the boot sequence to boot from the bootable media first.

4. Save the settings and restart the computer, the CentOS installation program will start automatically.

5. In the installer interface, select the appropriate language and keyboard layout.

6. Next, select the hard disk partitioning scheme, you can choose manual partitioning or automatic partitioning.

7. Set up the root partition and other necessary partitions, such as /boot and /swap.

8. After confirming the partition settings, select the installation location and start the installation.

9. During the installation process, you need to set the root user password and create a normal user.

10. After the installation is completed, restart the computer to enter the installed CentOS system.

The network installation steps are as follows:

1. Download the CentOS network installation image file and write it to a bootable media (such as a U disk or CD).

6. Connect to the network and select the network installation option.

7. Enter the correct URL or IP address of the network installation image file.

8. The installation program will download the installation media from the network and install it.

CentOS installation hardware requirements

CentOS has relatively low hardware requirements, but it still needs to meet certain configuration requirements to ensure system stability and performance.

The following are the hardware requirements for CentOS 7:

- Processor: 64-bit processor at least 1 GHz

- Memory: At least 1 GB of RAM (2 GB recommended Above)

- Hard disk space: At least 20 GB of available hard disk space

- Graphics card: Graphics card supporting 1024x768 resolution

- Network: Supports Ethernet connection

For CentOS 8 hardware requirements, there are some changes compared to CentOS 7:

- Processor: 64-bit processor with at least 2 GHz

- Memory: at least 2 GB of RAM (More than 4 GB recommended)

It should be noted that these hardware requirements are only the minimum requirements. In order to obtain better performance and stability, it is recommended to use higher configuration hardware in actual installation.

LINUX Little Knowledge

The file system of the LINUX operating system adopts a hierarchical structure, called a tree structure. The root directory (/) is the top directory of the file system, and all other Directories and files are located in the root directory. Each directory can contain other directories and files, forming a hierarchical relationship. Users can browse and operate files and directories in the file system by using the command line or graphical interface.
