OS installation / environment settings
Usage model
Raspberry Pi purchased the following. I just played around with it, so I could have used lower specs. I'm not sure, but if you buy a set, there's no problem! Purchased in the spirit of. https://www.amazon.co.jp/gp/product/B07ZRF5BC1/
SD card preparation
It seems that the file system must be FAT32. At first I was thinking of pulling out the SD card of Nintendo Switch and using it, This is used this time because it was enclosed in the above set.
Media creation with Raspberry Pi Imager
Download the exe file from the site
https://www.raspberrypi.org/downloads/
Install and start with administrator privileges
Specify the OS and write destination volume, and select [WRITE].
It took a while to complete. It may be a little over 30 minutes
OS settings
Insert the SD card into the Raspberry Pi, turn on the power, copy the display with the HDMI cable and operate
--Ssh enabled
--VNC enabled
Confirm activation

Check the IP address with ifconfig here and switch to work with SSH connection

Reboot once here and log in again
# shutdown -r now

--Modified sshd_config
Let's confirm the login while leaving the existing session.
# vi /etc/ssh/sshd_config
==Change the following====
PermitRootLogin no
PubkeyAuthentication yes
PasswordAuthentication no
--Alias setting
I tried to write it in .bashrc, but when I looked at the contents .bash_aliase seemed to be more suitable, so I wrote it there
# vi .bash_aliase
==Described below====
alias ll='ls -la --color=auto'
--Swap disabled
Reboot is required to reflect the settings
# swapoff --all
# systemctl stop dphys-swapfile
# systemctl disable dphys-swapfile
# free -h

--Disable unused log output
# vi /etc/rsyslog.conf
==Comment out the following====

I wanted to set a partition as well, but I stopped because it was annoying. Make logrotate settings enter after application installation
Get backup
Get a backup file in this state
Install Win32 Disk Imager https://sourceforge.net/projects/win32diskimager/
With Win32 Disk Imager running, connect the Raspberry Pi SD card to your work PC
File name of backup image in [ImageFIle]
Specify the device name that the SD card is recognized in [Device]
Backup acquisition is completed in about 30 minutes.
