목동코딩학원, ubuntu 서버 이전작업

지금 유지보수 하는 업체의 서버를 이전 해야할 필요가 생겼다.

서버 작업은 자주 하지 않다 보니 매번 새롭다.

게다가 버전을 맞추어 작업을 하다보니 몇 번을 해도 거의 같은 시간이 걸린다 ㅎㅎ

다음에 참조하기 위해 작업한 내용을 기록한다.

이번 작업은 클라우드 서버에 ubuntu, Docker등을 설치할 예정이다

----------------------------------

서버 : ubuntu 20.04

볼륨추가 : 1000Giga Byte

ubuntu@ubuntu1:~$ sudo su

Welcome to fdisk (util-linux 2.34).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Docker 설치

오래된 버전 삭제하기

혹시나 기존의 오래된 버전이 있는지 확실히 할 수 있으며, 있다면 최신 버전 설치를 위해 삭제 해줍니다.

bash

$ sudo apt-get update

$ sudo apt-get -y install \ apt-transport-https \ ca-certificates \ curl \ gnupg 
\ lsb-release 

curl -fsSL
[https://download.docker.com/linux/ubuntu/gpg](https://download.docker.com/linux/ubuntu/gpg)

| sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

echo \

"deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg]

[https://download.docker.com/linux/ubuntu](https://download.docker.com/linux/ubuntu)

\

$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Docker Engine 설치하기

아래 명령어를 입력하면 자동으로 최신 버전이 설치 됩니다.

$ sudo apt-get update

$ sudo apt-get install docker-ce docker-ce-cli

[containerd.io](http://containerd.io/)

설치 완료

설치가 완료된 후에는

bash

$docker --version

$apt install docker-compose

$cd /home/ubuntu/appnet
