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
