Long time no see
Recently, I got a new Raspberry Pi, and today I will update how to install the Raspberry Pi OS.
Considering that some readers may not know what a Raspberry Pi is, I will start with a brief introduction.
The Raspberry Pi, in English: Raspberry Pi, is a small, compact computer. It is powerful and can connect to devices such as computers, TVs, monitors, mice, and keyboards. It is called a single-board computer and can be used for browsing the web, playing games, learning programming, and running various pre-set programs.
There is a question on Zhihu: what can a Raspberry Pi be used for? Here are a few answers; if interested, you can check them out:
1. Website server
2. Private cloud storage
3. Smart home
4. Home theater system
5. Control RGB LED lights
6. Video surveillance
7. Robot control
8. Install GitLab to create a private Git service
…
To install the Raspberry Pi OS, just write the system to a removable storage SD card, insert it into the Raspberry Pi slot, and power it on.

Writing the system to the SD card
After writing, to allow the Raspberry Pi to connect to Wi-Fi directly, and to log into the Raspberry Pi OS using SSH tools, two preparatory steps are needed:
-
Open the boot drive letter, create a new ssh file without an extension. This opens the SSH service on the Raspberry Pi.
-
In the boot drive, create a wpa_supplicant.conf file with the following content:
country=CN
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid=”Your Wi-Fi Name”
psk=”Your Wi-Fi Password”
key_mgmt=WPA-PSK
priority=1
}
Insert the image SD card into the Raspberry Pi, provide power, wait a few minutes, and when you see the yellow light flashing, check your router list to see if a new network has joined. Record its IP.
Then you can use software like SecureCRT for remote connection.
The default username and password are: pi raspberry
Login successful!
Enable Raspberry Pi VNC
Enter the command line:
sudo raspi-config
Select option 5 Interfacing Options, press Enter
Select option 3: “VNC” and enable it.
Connect using a VNC client.
If it opens in a black screen state,
You need to adjust the resolution to resolve it.
Enter the command line: sudo raspi-config
Select 7 and press Enter
Select a resolution other than the first, finish and reboot.
Open again, success!
