Docker 설치

1. docker repo를 먼저 등록한다.

# yum update & register docker repo
> yum -y update
> yum install -y yum-utils
> yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

2. docker를 설치한다.

# install docker
> yum install -y docker-ce-20.10.7
> yum install -y docker-ce-cli-20.10.7
> yum install -y containerd.io-1.4.6

3. 설치한 docker를 실행한다.

# excute docker
> systemctl enable docker.service
> systemctl start docker

Docker-compose 설치

1. docker-compose를 내려받는다.

> curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

2. docker-compose 권한을 변경한다.

> chmod +x /usr/local/bin/docker-compose

3. 편하게 실행하도록 link도 하나 생성해준다. (Path에 등록해도 no 상관)

> ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

4. 실행시켜서 확인 ㄱ

> docker-compose -version
1.24.1
