基于CentOS的Docker安装教程

安装Docker详细步骤

1.更新yum源

sudo yum update

2.卸载旧版本的Docker

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

3.更改yum源为国内源

阿里云：

sudo yum-config-manager \
     --add-repo \
     https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

sudo sed -i 's/download.docker.com/mirrors.aliyun.com\/docker-ce/g' /etc/yum.repos.d/docker-ce.repo

官方源：

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

4.安装Docker依赖包

sudo yum install -y yum-utils \
     device-mapper-persistent-data \
     lvm2

5.安装Docker

sudo yum install docker-ce docker-ce-cli containerd.io

6.启动Docker

sudo systemctl start docker

7.设置Docker开机自启

sudo systemctl enable docker

卸载Docker

卸载全部相关软件包

sudo yum remove docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras

删除所有镜像、容器、卷

sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd
