Deployment and Maintenance / Official Raspberry Pi System Deployment

This document primarily describes how to run this system on a Raspberry Pi with the official Raspberry Pi OS installed.

Always use the latest version of DataFlux Func for operations

It is recommended to use a wired network connection during the operation process to connect to the Raspberry Pi

This article is based on operations performed on the Raspberry Pi 4B 8GB version. The Raspberry Pi 3B is too weak to run.

1. Preparation

Before installing DataFlux Func on the Raspberry Pi, some preparations are needed.

1.1 Burning the Raspberry Pi SD Card

It is recommended to burn the SD card using a clean official image before installing DataFlux Func.

When burning the SD card, you can choose:

  1. Use the official Raspberry Pi Imager tool to burn

  2. Directly download the official Raspberry Pi OS image and use third-party tools to burn

After burning is complete, simply insert the SD card into the Raspberry Pi and power it on to boot.

1.2 Enabling ARM 64-bit Mode

The official Raspberry Pi OS does not enable 64-bit mode for backward compatibility considerations. However, for products after the Raspberry Pi 3B, enabling 64-bit mode is supported.

You can open the Raspberry Pi configuration using the following command:

Bash
1
sudo vi /boot/config.txt

And add the following content to indicate enabling ARM 64-bit mode:

Text Only
1
arm_64bit=1

Save and restart the Raspberry Pi.

After restarting, you can confirm using the following command:

Bash
1
arch

The output should be as follows:

Text Only
1
aarch64

2. Installing DataFlux Func

The installation process of DataFlux Func on the Raspberry Pi is basically the same as on an ordinary server.

2.1 Downloading

The download process is the same as on other platforms; use the following command, which will detect the current environment architecture and download the ARM version resources.

Bash
1
/bin/bash -c "$(curl -fsSL func.guance.com/download)" -- --for=GSE
Bash
1
/bin/bash -c "$(curl -fsSL func.guance.com/download)"

GSE Edition and Old Editions

If you need to download the DataFlux Func installation package suitable for Raspberry Pi on a PC, specify --aarch64 in the download command.

Bash
1
/bin/bash -c "$(curl -fsSL func.guance.com/download)" -- --for=GSE --arch=aarch64
Bash
1
/bin/bash -c "$(curl -fsSL func.guance.com/download)" -- --arch=aarch64

2.2 Installation

After downloading, simply enter the downloaded directory and execute the following command to install:

Bash
1
sudo /bin/bash run-portable.sh

2.3 Initializing the System

After installation, open the DataFlux Func initialization page in your browser to proceed with the operation.

  • On the local Raspberry Pi, visit http://127.0.0.1:8088
  • From another device, visit http://{Raspberry Pi IP}:8088

2.4 Confirming Installation

After installation, log in to the system, go to "Manage / About", and you will see the "Architecture" as aarch64:

Subsequent operations are no different from DataFlux Func installed on a regular server.

3. Configuring WI-FI Connection

If you wish to have the Raspberry Pi connect via WI-FI after installing DataFlux Func, please read this section

After installing DataFlux Func, the taskbar's WI-FI control panel may prompt No wireless interfaces found, and you won't be able to connect to WI-FI via the UI. Meanwhile, the wired connection can still access the network normally.

This issue has been discovered during testing, but the cause is unclear, though it does not affect the wired connection.

3.1 Fixing the Raspberry Pi WI-FI Issue

To fix this problem, open the network configuration:

Bash
1
sudo vi /etc/network/interfaces

Add the following configuration:

Bash
1
2
3
4
5
auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-ssid {Your WI-FI SSID}
wpa-psk  {Your WI-FI Password}

Save and restart the Raspberry Pi.

3.2 Confirming the Problem Fix

Use the following command to confirm the WI-FI module:

Bash
1
iwconfig wlan0

The output content should be:

Text Only
1
2
3
4
5
6
7
8

          Bit Rate=72.2 Mb/s   Tx-Power=31 dBm

          Power Management:on
          Link Quality=70/70  Signal level=-35 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:254  Invalid misc:0   Missed beacon:0

Use the following command to confirm the WI-FI network connection:

Bash
1
ifconfig wlan0

The output content should be:

        TX packets 28599  bytes 22218944 (21.1 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Finally, open the browser and if you can access the internet normally, it means the WI-FI problem has been fixed.

You can also directly use cURL to verify whether the connection is successful:

Bash
1
curl -L function.guance.com/h

Even if the WI-FI problem has been fixed, the WI-FI control panel in the taskbar may still display No wireless interfaces found

X. Appendix

This section records some content related to the Raspberry Pi for reference.

X.1 Maximizing Raspberry Pi Performance

Open the /boot/config.txt file

Bash
1
sudo vim /boot/firmware/usercfg.txt

Add the following content according to your needs:

Text Only
1
2
3
4
5
force_turbo=0  # Prevent CPU from running at maximum frequency
arm_freq=2100  # Overclock CPU to 2.1Ghz (default is 1.5Ghz)
gpu_freq=750   # Overclock GPU to 750Mhz
gpu_mem=512    # Set graphics memory to 512MB
over_voltage=6 # Increase voltage to level 6

Even without the above settings, normal use is possible, and passive cooling with just a metal case is sufficient

This setting involves overclocking, and full load operation cannot rely solely on a metal case for passive cooling; at least one fan is required

More aggressive configurations can further enhance Raspberry Pi performance, but will void the warranty

If your Raspberry Pi is damaged due to overclocking, the author of this article assumes no responsibility. Please think carefully before proceeding

X.2 Raspberry Pi Stress Testing Program

You can use the Raspberry Pi stress test tool to test the stability of the Raspberry Pi's operation (especially after overclocking).

Pull the project repository

Bash
1
git clone https://gitee.com/sujivin/rpi-cpu-stress.git

The original author's Github repository address is: github.com/xukejing/rpi-cpu-stress

Add executable permissions

Bash
1
2
cd rpi-cpu-stress
chmod +x stress.sh

Start the stress test

Text Only
1
sudo ./stress.sh

In the terminal, you can see the following output:

a72 freq: 2100000
temp: 55991

a72 freq: 2100000
temp: 56478
  • a72 freq: 2100000: Indicates the current CPU frequency is 2.1Ghz
  • temp: 50634: Indicates the temperature is 50.634 degrees Celsius

Do not let the Raspberry Pi stay at high temperatures (above 80 degrees Celsius) for long periods

X.3 Installing Chinese Input Method on Raspberry Pi

Execute the following command in the terminal to install the "Zhongzhou Yun" input method:

Bash
1
sudo apt-get install fcitx fcitx-rime

After completion, add the "Zhongzhou Yun" input method under "Preferences -> Fcitx Configuration -> Add Input Method".

X.4 Installing Chinese Fonts on Raspberry Pi

Execute the following command in the terminal to install the "WenQuanYi" font:

Bash
