dnf基址怎么用　dnf官方补丁

dnf是下一代的yum，Linux上的包管理工具。接下来我们使用dnf安装docker。

sudo dnf install docker-ce --nobest

说明：

1、 只需要安装 docker-ce 即可，相关依赖会自动安装，以下是自动安装的依赖清单：

container-selinux\ncontainerd.io\ndocker-ce-cli\ndocker-ce-rootless-extras\nfuse-overlayfs\nfuse3\nfuse3-libs\nlibslirp\nslirp4netns\nnstalling weak dependencies:\ndocker-buildx-plugin\ndocker-compose-plugin

2、--nobest参数允许在安装过程中使用一些次优的依赖选项；

安装完成之后，输入docker版本查看命令：

docker --version\nDocker version 24.0.6, build ed223bc

设置为开机启动

systemctl enable docker\nCreated symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.\n

说明：

1、该不会立即启动 docker，只有重启服务器的时候，docker 才会跟随启动；

2、如果要在设置开机启动的时候同时启动 docker 服务，使用以下命令：

systemctl enable --now docker

systemctl stop docker

卸载程序

dnf remove docker-ce

目录清理

[root@iZ2zebo1wkvuti2lmbakteZ lib]# du -sh ./docker/\n753M ./docker/

rm -rm /var/lib/docker
