#### 1，卸载旧版本 ####

$ yum remove docker \
                      docker-client \
                      docker-client-latest \
                      docker-common \
                      docker-latest \
                      docker-latest-logrotate \
                      docker-logrotate \
                      docker-engine

#### 2，需要的安装包 ####

[root@localhost roo]# yum install -y yum-utils
    这一步可以yum可能报错，如果报错了，执行下面的语句，没问题这不用执行
    [root@localhost roo]# rm -f /var/run/yum.pid

#### 3，设置镜像仓库 ####

[root@localhost roo]# yum-config-manager \
        --add-repo \
        http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

#### 4，安装docker相关 ####

[root@localhost roo]# sudo yum install docker-ce docker-ce-cli containerd.io

#### 5，启动docker ####

[root@localhost roo]# system start docker

#### 6，查看是否安装成功 ####

[root@localhost roo]# systemctl start docker

#### 7，执行hello-word ####

[root@localhost roo]# docker run hello-world

说明安装成功

#### 8，查看一下镜像 ####

[root@localhost roo]# docker images
    REPOSITORY    TAG       IMAGE ID       CREATED         SIZE
    hello-world   latest    bf756fb1ae65   11 months ago   13.3kB

#### 9，卸载(一般不用) ####

1，卸载依赖
    yum remove docker-ce docker-ce-cli containerd.io
    2、删除镜像/容器等
    rm -rf /var/lib/docker

#### 10，阿里云加速 ####

sudo mkdir -p /etc/docker
    sudo tee /etc/docker/daemon.json <<-'EOF'
    { 
      "registry-mirrors": ["https://9xj7kbt8.mirror.aliyuncs.com"]
    }
    EOF
    sudo systemctl daemon-reload
    sudo systemctl restart docker

##### 无用，做时代码 #####

    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
