简介
yum 是 Linux 的在线安装方式，是比较方便的。
由于 yum 是在线安装，需要从网络获取数据，所以得先保证系统是能联网的，否则一定会安装失败。
这里使用安装 Docker 作为示例。
操作
安装
官网安装参考手册：https://docs.docker.com/install/linux/docker-ce/centos/
yum -y install
语法
yum -y install 程序名
参数
-y：所有的 yes / no 都选择 yes，确定安装时都选择 yes 时可以使用，可以省去一些选择步骤。
系统版本检测
本次示例基于 CentOS 7 进行演示，所以需要先确认系统的版本。
[root@sail ~]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
安装运行环境
由于 Docker 是基于 C 和 C++ 开发的，所以需要先安装相关环境。
- 安装 C 环境。使用如下命令：
yum -y install gcc
[root@sail ~]# yum -y install gcc
Loaded plugins: fastestmirror

卸载以前的 Docker
为避免版本之间的冲突，这里建议先卸载以前的版本再进行安装。

设置镜像仓库
这里官网建议我们安装国外的镜像仓库
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
但由于对国外的网络限制，国内安装的话会非常慢，并很有可能失败，报如下错误。
[Errno 14] curl#35 - TCP connection reset by peer
[Errno 12] curl#35 - Timeout
推荐国内用户安装阿里云镜像
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@sail ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装 Docker
做完前面的准备工作，就可以开始安装 Docker 了
yum -y install docker-ce docker-ce-cli containerd.io
这里的
docker-ce指的是 Docker 的社区版，如果是需要企业版的话就改为docker-ee，不过企业版是收费的，而且功能也略有不同，官方更推荐社区版，所以这里我们安装docker-ce。
[root@sail ~]# yum -y install docker-ce docker-ce-cli containerd.io

启动 Docker
Docker 安装完成后，就可以运行如下命令启动。
systemctl start docker
[root@sail ~]# systemctl start docker
[root@sail ~]#
测试
启动 Docker 后，我们可以运行如下命令对 Docker 进行测试。
- 查看 Docker 进程。
[root@sail ~]# ps -ef|grep docker
root 18805 1 0 16:54 ? 00:00:00 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
root 19233 16612 0 16:59 pts/0 00:00:00 grep --color=auto docker
由此可以看出，Docker 是启动成功了的。
- 查看版本信息。
[root@sail ~]# docker version

可以看出 Docker 的版本为 20.10.11。
- 运行 Hello World 镜像。
Hello World 镜像是 Docker 官方为测试 Docker 环境和运行情况所设定的一个程序。
docker run hello-world
[root@sail ~]# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
2db29710123e: Pull complete
Digest: sha256:cc15c5b292d8525effc0f89cb299f1804f3a725c8d05e158653a563f15e4f685
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:
https://hub.docker.com/
For more examples and ideas, visit:
https://docs.docker.com/get-started/
由以下结果可以看出，我们的 Docker 工作环境是搭建完毕了的。
Hello from Docker!
This message shows that your installation appears to be working correctly.
- 查看镜像。
在执行启动 Hello World 镜像的命令时，如果本地没有该镜像，会先从镜像库中拉取该镜像再启动。
使用
docker images查看目前的 Docker 的镜像情况：
[root@sail ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
hello-world latest feb5d9fea6a5 2 months ago 13.3kB
这里我们可以看到刚拉取的 hello-world 镜像，以及它的相关信息。
阿里云镜像加速
如果是阿里云的服务器，还可以使用阿里云的镜像加速使得 Docker 使用起来更加快速和高效。
- 打开阿里云服务器列表，选择如图所示的容器镜像服务。
- 选择如图所示的镜像加速器，然后选择对应的服务器系统。
- 在服务器上依次执行上图所示的4条命令即可实现阿里云的镜像加速。
至此，yum 方式安装 Docker 完毕。
