Detailed steps to install 64-bit Ubuntu system and Docker tool on Raspberry Pi 3B+

If you want to install some 64-bit applications (such as 64-bit JDK) on the Raspberry Pi 3B, you must first install a 64-bit operating system. Today, let's do this together.

The environment requires a Raspberry Pi 3B device; the network environment is an intranet, which requires a wired network and a network cable; when the Raspberry Pi is connected to the intranet through a network cable, the IP of the Raspberry Pi can be found on the router management software. For example, I use a Xiaomi router, and I can see the access status of the Raspberry Pi through the router management page or the Xiaomi router APP; a card reader; a computer with a Windows 10 system; the three softwares SecureCRT, SDFormatter, and Win32DiskImager are installed on the computer;

Operation steps list

Let’s review all the steps first:

Download 64-bit operating system image; format memory card; burn image to memory card; start Raspberry Pi; remote connection; basic settings; install 64-bit application and verify;

Once you are ready, start the actual combat;

Download 64-bit OS image

Someone has made a 64-bit image and put it on GitHub at: https://github.com/bamarni/pi64/releases. As shown in the figure below, there are desktop and non-desktop versions. I chose the non-desktop version, as shown in the red box below:

After downloading, unzip it and you will get the file pi64-lite.img, which is less than 500M.

Formatting a memory card

Insert the memory card into the card reader, insert the card reader into the computer, then start the SDFormatter software, click the format button in the lower right corner to start formatting, as shown below:

During the formatting process, it may prompt that the formatting failed, as shown in the following figure. At this time, formatting again will succeed:

Burn the image to the memory card

Open Win32DiskImager, select the pi64-lite.img file you just downloaded, and click the Write button to start burning, as shown below:

After burning is complete, insert the memory card into the card slot of the Raspberry Pi;

Start the Raspberry Pi and plug the network cable connected to the intranet into the network port of the Raspberry Pi. Connect the power and start the Raspberry Pi.

Remote connection: Use the router management system to find the IP address of the Raspberry Pi. For example, I use the Android APP of the Xiaomi router. As shown in the figure below, the Raspberry Pi device is in the red box. Click it to see the IP address. Assume that the IP address here is 192.168.31.86:

Open SecureCRT and create a new SSH connection with the Raspberry Pi, username pi, password raspberry. The connection is successful and the following information is displayed:

Linux raspberrypi 4.11.12-pi64+ #1 SMP PREEMPT Sun Jul 30 20:18:20 CEST 2017 aarch64

3. Use the uname -a and getconf LONG_BIT commands to verify whether it is a 64-bit system, as follows: ```shellroot@raspberrypi:/home/pi# uname -aLinux raspberrypi 4.11.12-pi64+ #1 SMP PREEMPT Sun Jul 30 20:18:20 CEST 2017 aarch64 GNU/Linuxroot@raspberrypi:/home/pi# getconf LONG_BIT64```It is indeed a 64-bit system;

Basic Settings

Next, do some basic setup:

First, change the root password. Then we can use the root account to perform various operations. The command is sudo passwd root. Enter the new root password twice as prompted, and then you can su to the root identity. Execute the command apt-get update as root to make an update. Next, we will do some basic settings, such as time zone, hostname, wireless network, etc. Enter the command pi64-config as root, and the following interface will appear. Please set them one by one according to your needs:

After the WIFI settings are completed, you can see the latest Raspberry Pi device connected wirelessly on the router management page, as shown below:

Now you can unplug the network cable, write down the IP address of the wirelessly connected Raspberry Pi, and then create a new SSH connection with the Raspberry Pi in SecureCRT;

Install 64-bit applications and verify

This verification uses a 64-bit JDK:

Install the vi tool and execute the command apt-get install vim -y; first install the upload and download tools on the Raspberry Pi and execute the command apt-get install lrzsz -y; go to the JDK download page on the computer, address: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html, as shown below, first click the option in the green box, and then click jdk-8u172-linux-arm64-vfp-hflt.tar.gz in the red box, which is the version available for the Raspberry Pi:

After the file is downloaded, execute the rz command on SecureCRT to download the file to the Raspberry Pi; execute the command tar -zxvf jdk-8u172-linux-arm64-vfp-hflt.tar.gz on SecureCTR to decompress the file; move the decompressed folder to the /usr/local directory: mv jdk1.8.0_172 /usr/local/; open the file /etc/profile and add the following content:

export JAVA_HOME=/usr/local/jdk1.8.0_172
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib/dt.JAVA_HOME/lib/tools.jar:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:${PATH}

8. Make the configuration take effect immediately: source /etc/profile; 9. Check the current java version information: java -version, you can see the following basic content: ```shellroot@raspberrypi:/usr/local/jdk1.8.0_172# java -versionjava version "1.8.0_172"Java(TM) SE Runtime Environment (build 1.8.0_172-b11)Java HotSpot(TM) 64-Bit Server VM (build 25.172-b11, mixed mode)```

At this point, the 64-bit system has been successfully installed on the Raspberry Pi and verified successfully;
