1. Preparation of Raspberry Pi
- Into the Ubuntu official website to download the support Raspberry Pi version of Ubuntu installation package.
- Use DiskGenius to format the SD card, delete all sectors, and then format.
- Download the official burning tool , select the .xz file just downloaded for the mirror image, select your own card for the SD card, and just write it.
Two, Ubuntu system configuration
2.1 Enter Ubuntu system
Insert the TF card into the Raspberry Pi. The system can be initialized and configured through the display, or the Raspberry Pi can be connected to the computer with a network cable for remote configuration. It is recommended to use an external monitor, the operation will be much simpler. Take the use of an external screen + keyboard as an example (these devices only need to be used once)
- Insert the previously made SD card into the Raspberry Pi, and connect the power supply to the Raspberry Pi (the power supply can be a 2.5mm round head power cord, or a microUSB or TypeC interface line, but the charging head is required to reach 5V 3A, the minimum 5V 2.5A)
- Power on, wait for a period of time to enter the system, you first need to log in, the initial user name and password are both ubuntu , after logging in, you will be asked to reset the password.
2.2 wifi settings
cd /etc/netplan
In this directory, if it is a server, there will be a 50-cloud-init.yaml file, if it is a desktop environment, there will be a 01-network-manager-all.yaml,
where 50-cloud-init.yaml is For example, edit a file:
pay attention to the indentation format of the file,
network:
version: 2
wifis:
wlan0:
dhcp4: true
optional: true
access-points:
"你的wifi名称":
password: "wifi密码"
Then execute the command to make the configuration effective
sudo netplan generate
sudo netplan apply
Enter the command ifconfigto view the ip address, and use the remote access tool to access it.
