Linux不同发行版安装Docker全步骤

一、CentOS安装Docker

使用安装脚本安装

sudo yum update
curl -fsSL https://get.docker.com/ | sh
systemctl start docker 
systemctl enable docker

手动安装

卸载原有版本

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

安装Docker依赖库

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

安装Docker引擎

sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
sudo systemctl start docker
sudo systemctl enable docker

docker run hello-world

二、Ubuntu安装Docker

使用安装脚本安装

# 保证机器没有安装过docker
# 如果没安装过docker这步可以省略
sudo apt-get purge docker-ce docker-ce-cli containerd.io
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd

# 下载安装脚本并运行
sudo apt update
curl -fsSL https://get.docker.com | sh
systemctl start docker 
systemctl enable docker

手动安装

安装Docker依赖库

sudo apt-get -y install ca-certificates curl gnupg lsb-release

# 添加Docker pgp密钥 二选一
# 国内源
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/debian/gpg | \
    sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

# 官方源
curl -fsSL https://download.docker.com/linux/debian/gpg | \
    sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

# 添加Docker apt源 二选一
# 国内源
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/debian \
    $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# 官方源
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian \
    $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

安装Docker引擎

sudo apt-get update -y
sudo apt-get -y install docker-ce docker-ce-cli containerd.io docker-compose-plugin

docker run hello-world

三、配置国内镜像源

# 配置阿里云镜像加速
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://7kcin9o3.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
sudo docker info

四、安装docker-compose

curl -SL https://github.com/docker/compose/releases/download/v2.19.0/docker-compose-linux-x86_64 
mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose

docker-compose version
