注意需要使用 root 账户或者可以使用 sudo 的账户

1、安装 Docker

# 安装依赖
sudo yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

# 添加docker下载仓库
sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

# 安装docker-ce
sudo yum install docker-ce

# 启动docker-ce
sudo systemctl start docker

# 验证
sudo docker --version

sudo docker run hello-world

2、安装 docker-compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

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

docker-compose --version

若是github访问太慢，可以用daocloud下载

sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

添加可执行权限

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

测试安装结果

docker-compose --version
