This guide will teach you how to quickly make an Ubuntu Operation System SD card, boot it on Raspberry Pi 4, and set up the iDempiere server.
- A microSD card ( 32GB to 128GB)
- A computer with a microSD card drive
- A Raspberry Pi 4 B ( 4G or 8G Ram)
- A USB-C power cable
- A Wi-Fi network or an ethernet cable with an internet connection
- A monitor with an HDMI interface
- An HDMI cable for the Pi 2 & 3 and a micro HDMI cable for the Pi 4
- A USB keyboard
Prepare the SD Card
Download Raspberry Imager from the raspberry pi official website.
I use MacOS to demonstrate.

Once it’s set, you can grill it
Connect to Raspberry Pi 4
After the Raspberry Pi has been booted, you can connect to it using Secure Shell (SSH).
If you don’t know the IP address of your Raspberry Pi, you can use a network scanner tool like “Angry IP Scanner” or “Advanced IP Scanner” to scan your network and find the IP address of your Raspberry Pi. Once you have the IP address, you can use an SSH client like PuTTY (Windows OS Only) to connect to your Raspberry Pi. Alternatively, you can connect your Raspberry Pi to a monitor and keyboard and use the command “ifconfig” in the terminal to display its IP address.

Change password to user postgres
sudo su postgres psql alter user postgres password 'postgres_password'
Prepare iDempiere Installer
You can build an installer from the iDempiere source code. Or directly download it from the official website.
wget https://sourceforge.net/projects/idempiere/files/v9/daily-server/idempiereServer9Daily.gtk.linux.x86_64.zip #Extract file unzip idempiereServer9Daily.gtk.linux.x86_64.zip
# initial configuration properties cd idempiere.gtk.linux.x86_64/idempiere-server sh console-setup-alt.sh # Refer to the prompt question to enter the parameters, if you don't know, just keep pressing the ENTER key # Change to utils directory cd utils # Import seed into database RUN_ImportIdempiere.sh # RUN_SyncDB.sh
Tuning iDempiere ERP Performance
To configure iDempiere memory settings, you can follow these steps:
- Locate the
myEnvironment.shfile in the iDempiere installation directory’s utils directory.
- Open the file in a text editor.
- Search for the
- Set the desired memory settings using the
-Xms(initial heap size) and
-Xmx(maximum heap size) flags. For example:makefileCopy code
JAVA_OPTS="-Xms2048m -Xmx2048m"This would set the initial heap size to 2048 MB and the maximum heap size to 2048 MB.
- Save the changes to the
- Restart the iDempiere server for the changes to take effect.
Note that the optimal memory settings may vary depending on the size of your iDempiere database and the number of users accessing the system. It’s recommended to monitor system performance and adjust the memory settings as necessary.
