安装Docker流程

1.卸载旧版首先如果系统中已经存在旧的Docker则先卸载yum remove docker \ docker-client \ docker-client-latest \ docker-common \ docker-latest \ docker-latest-logrotate \ docker-logrotate \ docker-engine2.配置Docker的yum库首先要安装一个yum工具yum install -y yum-utils安装成功后执行命令配置Docker的yum源sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo3.安装Docker最后执行命令安装Dockeryum install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin4.启动和校验# 启动Docker systemctl start docker # 停止Docker systemctl stop docker # 重启 systemctl restart docker # 设置开机自启 systemctl enable docker # 执行docker ps命令如果不报错说明安装启动成功 docker ps5.配置镜像加速sudo tee /etc/docker/daemon.json EOF { registry-mirrors: [ https://docker.211678.top, https://docker.1panel.live, https://hub.rat.dev, https://docker.m.daocloud.io, https://do.nark.eu.org, https://dockerpull.com, https://dockerproxy.cn, https://docker.awsl9527.cn ] } EOFsystemctl restart docker
