久々にラズパイを触ったので忘却録として書きます。
------------- ラズパイにOSとNode-Redを新規インストールをする方法
高速なmicroSD（v30規格など）又は
高速なUSBメモリ（書き込み速度最大８０MBなど）を購入する。
間違えても速度をうたっていない遅いものは買わない。
（最初遅いUSBを買ったため起動に７分もかかった。）
------------- インストール作業手順
windows又はmacパソコンで
１．Raspberry Pi imager
https://www.raspberrypi.org/software/
又は
Disk FORMATTER（管理者権限）で３２GB以上でもFAT３２でフォーマットする。(win)
https://www.buffalo.jp/support/download/detail/?dl_contents_id=60879
又は
本体のディスクユーティリティで３２GB以上でもFAT３２でフォーマットする。(mac)
２．Raspberry Pi imagerを使ってインストールする。
３．マイクロSDやUSBメモリをラズパイに入れて起動する。
４．設定ーRasperry Pi の設定ーローカライゼーションの順に行って、
ローカル、タイムゾーン、キーボード、無線LANの国を設定する。
------------- 日本語のインストール -----------------------
ターミナルから
sudo apt update
sudo apt upgrade
sudo apt-get install fcitx-mozc -y
im-config -n fcitx
sudo reboot
又は
sudo apt install ibus-mozc
sudo reboot
------------- VNCサーバーの設定 -----------------------
左上のラズパイマークからー設定ーRasperry Pi の設定ーインターフェイス
SSHとVNCを有効にする。
右上のVNCマークを開きIPを確認する。
------------- ファイル共有Sambaのインストール -----------------------
ターミナルから
sudo apt update
sudo apt upgrade
sudo apt install samba
pi@raspberrypi ~ $ sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.bak
pi@raspberrypi ~ $ sudo nano /etc/samba/smb.conf
ファイルの変更内容について
参考サイト

以下 抜粋
まず、最初の方に [global] ブロックがありますので、ここに文字コードを以下のように追加記入します。
--
変更前:
[global]
変更後:
[global]
unix charset = UTF-8
dos charset = CP932
#======================= Share Definitions =======================
というところがあります。このブロックで以下の3か所の変更をします。
まず1つ目です。これはファイルの書き込みを許可するように変更する設定です。
--
変更前:
# By default, the home directories are exported read-only. Change the
# next parameter to 'no' if you want to be able to write to them.
read only = yes
変更後:
# By default, the home directories are exported read-only. Change the
# next parameter to 'no' if you want to be able to write to them.
read only = no
2つ目はファイルのパーミッションを緩くする設定です。
--
変更前:
# File creation mask is set to 0700 for security reasons. If you want to
# create files with group=rw permissions, set next parameter to 0775.
create mask = 0700
変更後:
# File creation mask is set to 0700 for security reasons. If you want to
# create files with group=rw permissions, set next parameter to 0775.
create mask = 0664
--
変更前:
# Directory creation mask is set to 0700 for security reasons. If you want to
# create dirs. with group=rw permissions, set next parameter to 0775.
directory mask = 0700
変更後:
# Directory creation mask is set to 0700 for security reasons. If you want to
# create dirs. with group=rw permissions, set next parameter to 0775.
directory mask = 0775
これで設定が終わりましたので、control + Oで保存、Control + Xでnanoを終了します。

# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
