## 2、安装docker
\[root@localhost \~\]# **yum install docker-ce -y**

## 3、启动docker
\[root@localhost \~\]# **docker -v \&\& systemctl restart docker \&\& systemctl enable docker**
Docker version 27.3.1, build ce12230
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.
## 4、运行/拉取镜像测试
\[root@localhost \~\]# **docker run hello-world**
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

Digest: sha256:305243c734571da2d100c8c8b3c3167a098cab6049c9a5b066b6021a60fcb966
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
