Docker安装教程

Docker安装步骤

一、CentOS

目前 Docker 只能支持 64 位系统。

systemctl stop firewalld.service
setenforce 0

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


#设置阿里云镜像源
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 

#安装 Docker-CE并设置为开机自动启动
yum install -y docker-ce docker-ce-cli containerd.io

systemctl start docker.service
systemctl enable docker.service 



#查看 docker 版本信息
docker version

#docker 信息查看
docker info 

二、debian

sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://mirrors.aliyun.com/docker-ce/linux/debian \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
 
#安装 Docker并设置为开机自动启动
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y


systemctl start docker.service
systemctl enable docker.service 



#查看 docker 版本信息
docker version

#docker 信息查看
docker info 

三、Ubuntu

#curl 命令安装
sudo apt install curl -y

#创建 gpg key 目录
sudo mkdir -m 0755 -p /etc/apt/keyrings

#下载 gpg key
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.gpg

echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# 安装Docker
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y
