The environment requirements for full-automatic installation of openEuler using kickstart are as follows:
- PM/VM \(for details about how to create VMs, see the documents from corresponding vendors\): includes the computer where kickstart is used for automatic installation and the computer where the kickstart tool is installed.
- Httpd: stores the kickstart file.
- TFTP: provides vmlinuz and initrd files.
- DHCPD/PXE: provides the DHCP service.
- ISO: openEuler-1.0-base-aarch64-dvd.iso
## Procedure<a name="section9467123415317"></a>
To use kickstart to perform full-automatic installation of openEuler, perform the following steps:
>Before the installation, ensure that the firewall of the HTTP server is disabled. Run the following command to disable the firewall:
>```
>iptables -F

1. Install httpd and start the service.
```
# dnf install httpd -y
# systemctl start httpd
# systemctl enable httpd
```
2. Install and configure TFTP.
```
# dnf install tftp-server -y
# vim /etc/xinetd.d/tftp

Moreover, Only a virtualization platform created by the virtualization components \(openEuler as the host OS and QEMU and KVM provided in the release package\) of openEuler is supported. Currently, only installation modes such as CD-ROM, USB flash drive, and network are supported.
# Installation Through a USB Flash Drive<a name="EN-US_TOPIC_0229291281"></a>
This section describes how to create or use a USB flash drive to install the openEuler.
## Preparing the Installation Source<a name="en-us_topic_0022605797_en-us_topic_0018374843_section16523819201222"></a>
Pay attention to the capacity of the USB flash drive. The USB flash drive must have sufficient space to store the entire image. It is recommended that the USB flash drive has more than 16 GB space.
1. Connect the USB flash drive to the system and run the **dmesg** command to view related log. At the end of the log, you can view the information generated by the USB flash drive that is just connected. The information is similar to the following:
```
[ 170.171135] sd 5:0:0:0: [sdb] Attached SCSI removable disk
Replace **/path/to/image.iso** with the complete path of the downloaded ISO image file, replace **device** with the device name provided by the **dmesg** command, and set a proper block size \(for example, 512 KB\) to replace **blocksize** to accelerate the write progress.
For example, if the ISO image file name is **/home/testuser/Downloads/openEuler-1.0-base-aarch64-dvd.iso** and the detected device name is **sdb**, run the following command:
5. After the image is written, remove the USB flash drive.
No progress is displayed during the image write process. When the number sign \(\#\) appears again, the write is complete. Exit the **root** account and remove the USB flash drive. In this case, you can use the USB flash drive as the installation source of the system.
## Starting the Installation<a name="en-us_topic_0022605797_en-us_topic_0018374843_section61839653201222"></a>
Perform the following operations to start the installation:
>Set the system to preferentially boot from the USB flash drive. Take the BIOS as an example. You need to move the **USB** option under **Boot Type Order** to the top.
1. Disconnect all drives that are not required.
2. Open your computer system.
3. Insert the USB flash drive into the computer.
4. Restart the computer system.
After a short delay, a graphical wizard page is displayed, which contains different boot options. If you do not perform any operation within one minute, the installation program automatically starts the installation.
# Installation Through the Network Using PXE<a name="EN-US_TOPIC_0229291253"></a>
To boot with PXE, you need to properly configure the server and your computer's network interface to support PXE.
If the target hardware is installed with a PXE-enabled NIC, we can configure it to boot the computer from network system files rather than local media \(such as CD-ROMs\) and execute the Anaconda installation program.
For installation through the network using PXE, the client uses a PXE-enabled NIC to send a broadcast request for DHCP information and IP address to the network. The DHCP server provides the client with an IP address and other network information, such as the IP address or host name of the DNS and FTP server \(which provides the files required for starting the installation program\), and the location of the files on the server.
>The TFTP, DHCP, and HTTP server configurations are not described here. For details, see [Full-automatic Installation Guide](full-automatic-installation-guide.html).
You can use the kickstart tool to automatically install the openEuler OS in either of the following ways:
- Semi-automatic installation: You only need to specify the location of the kickstart file. Kickstart automatically configures OS attributes such as keyboard, language, and partitions.
- Automatic installation: The OS is automatically installed.
## Advantages and Disadvantages<a name="section161817592328"></a>
[Table 1](#table1388812373315) lists the advantages and disadvantages of semi-automatic installation and full-automatic installation using kickstart. You can select an installation mode as required.

## Background<a name="section13181456141811"></a>
**Kickstart**
Kickstart is an unattended installation mode. The principle of kickstart is to record typical parameters that need to be manually entered during the installation and generate the configuration file **ks.cfg**. During the installation, the installation program searches the **ks.cfg** configuration file first for required parameters. If no matching parameters are found, you need to manually configure these parameters. If all required parameters are covered by the kickstart file, automatic installation can be achieved by only specifying the path of the kickstart file.
Both full-automatic or semi-automatic installation can be achieved by kickstart.
**PXE**
Pre-boot Execution Environment \(PXE\)\) works in client/server network mode. The PXE client can obtain an IP address from the DHCP server during the startup and implement client boot and installation through the network based on protocols such as trivial file transfer protocol \(TFTP\).
**TFTP**
TFTP is used to transfer simple and trivial files between clients and the server.
