systemd/Timers
archlinux를 기본설치하면 cron이 설치되지 않는다.
cronie 를 설치할까하다, systemd/Timers 를 이용하여 매일 package를 업데이트하도록 설정한다.

Oracle cloud shell
oracle cloud 서버에 접속하기 위해 cloud shell에 접속환경을 만들었다.
ssh key 생성
아래와 같이 private key, public key 생성
yongsub_yu@cloudshell:~ (ap-seoul-1)$ ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/home/yongsub_yu/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/yongsub_yu/.ssh/id_rsa. Your public key has been saved in /home/yongsub_yu/.ssh/id_rsa.pub. The key fingerprint is: The key's randomart image is: +---[RSA 2048]----+ | .o .+ | | .. = +=o. o| | .B BEoo+ +.| | ..+o=.=.. = | | o.oSo o + . | | ...o . . + | | .. o . | | . o +... | | . =ooo.+| +----[SHA256]-----+
접속대상 서버의 .ssh/autorized_key 파일에 위에서 생성된 public_key 등록
접속할 서버 .ssh/config 에 등록

firewall 정책 추가
Oracle cloud free tier vm benchmark
Oracle cloud free tier Ampere Arm A1 를 설치하고 기존 E2.1.Micro 머신과 성능면에서 어떤 차이가 있는지 테스트 해보았다.
생성한 인스턴스는 3개이다.
E2 머신은 2개까지 생성할 수 있으며 각각 1 OCPU, 1GB MEM 이다.
A1 머신은 arm 4 OCPU, 24GB MEM이다.
그리고 스토리지는 200GB까지 제공된다.
