Split the article into several pieces, because the contents is long.

Set up Raspberry Pi

I use raspberry Pi 3 Model B what was used in the past.

Refer to the following to initialize the microSD, Write Rasbian on microSD.

Raspberry Piに Raspbian をインストールする for Mac OSX
- https://qiita.com/ttyokoyama/items/7afe6404fd8d3e910d09

Choise Raspbian.

Raspbian
- https://www.raspberrypi.org/downloads/raspbian/

Download on Hostmachine, Write Rasbian on microSD.

Then My Work is running from macOS.

After pyhical mount micoSD on hostmachine, Check from your terminal.

/dev/disk2s1 is microSD, therefore unmount from your terminal

sudo diskutil umount /dev/disk2s1
sudo diskutil unmountDisk /dev/disk2

### Example

$ sudo diskutil umount /dev/disk2s1
Password:
Volume (null) on disk2s1 unmounted
$ sudo diskutil unmountDisk /dev/disk2
Unmount of all volumes on disk2 was successful

Check image of Raspbian Buster with desktop

$ ls ~/Desktop/2019-09-26-raspbian-buster.img
/Users/iganari/Desktop/2019-09-26-raspbian-buster.img

Write Rasbian on microSD using dd command.

sudo dd bs=1m if=~/Desktop/2019-09-26-raspbian-buster.img of=/dev/disk2

### Example

$ sudo dd bs=1m if=~/Desktop/2019-09-26-raspbian-buster.img of=/dev/disk2

It took about 5 hours to complete...

Physically remove and insert microSD for remount.

You can see that Linux has been added to / dev / disk2.

Next, you insert this microSD in Raspberry Pi, and Power on.

Success!!

Set up Raspbian Buster with desktop

First, let's set up Wifi.

This time, Set up IEEE802.11b only.

Because Raspberry Pi 3 Model B can only set IEEE802.11b/g/n.

If Raspberry Pi 3 Model B+, I can set IEEE802.11a.

Raspberry Pi 3 Model B
- https://www.iodata.jp/product/pc/raspberrypi/ud-rp3/spec.htm
Raspberry Pi 3 Model B+
- https://www.iodata.jp/product/pc/raspberrypi/ud-rp3bp/spec.htm

I shoud have checked spec...

I pulled myself together and Setting Raspbian.

Updating packages

Updating packages using apt command.

sudo apt-get update
sudo apt-get upgrade

Set up SSH login

Install openssh-server

sudo apt-get install openssh-server

Set the automatic startup of the ssh daemon.

sudo systemctl start ssh
sudo systemctl enable ssh

reboot for checking.

sudo shutdown -r now

After restarting, if you can SSH login to this Raspberry Pi from another PC, the setting is completed.

Changing the standard editor

Raspbian's standard editor is nano. However, it may be confusing for users who do not normally use nano.

In such a case, change the standard editor. Here is how to change the standard editor to Vim.

install Vim package using apt command.

sudo apt install vim

Check that the installation has been completed.

sudo apt list --installed | grep vim

### Example

$ sudo apt list --installed | grep vim

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

vim-common/stable,now 2:8.1.0875-5 all [installed]
vim-runtime/stable,now 2:8.1.0875-5 all [installed,automatic]
vim-tiny/stable,now 2:8.1.0875-5 armhf [installed]
vim/stable,now 2:8.1.0875-5 armhf [installed]

Check the existing standard editor.

$ ls -la /etc/alternatives/editor
lrwxrwxrwx 1 root root 9 Sep 26 09:08 /etc/alternatives/editor -> /bin/nano

Replace the existing standard editor.

sudo unlink /etc/alternatives/editor
sudo ln -s /usr/bin/vim.basic /etc/alternatives/editor

Recheck the standard editor.

$ ls -la /etc/alternatives/editor
lrwxrwxrwx 1 root root 18 Jan  4 14:00 /etc/alternatives/editor -> /usr/bin/vim.basic

Uninstall nano.

sudo apt remove --purge nano

Conclusion

For now, I was able to replace the Raspberry Pi. That's it for today's work.

I will install Node-RED in the next article.

Thanks for reading this article :)
