원격으로 SSH 접속 가능하도록 수정하는 방법

# VM을 SSH로 접근하기

- 아래의 유틸을 설치하자

sudo apt-get update

sudo apt-get install openssh-server

sudo apt-get install gedit

- SSH 설정 편집

sudo gedit /etc/ssh/sshd_config

- 주석 제거 후 저장

- VM의 IP주소를 확인하기 위해 설치

sudo apt install net-tools

ifconfig

- eth0 의 ip를 메모장에 기록 합니다.

- SSH에 접근해 봅시다

ssh {계정명}@{vm의 ip}

ssh k8s-master-node@192.168.137.50

- 접속 성공 (이젠 편하게 작업할 수 있겠다...)
