这里需要注意，如果你之前安装过docker是先要把旧版本卸载掉的，相关命令再此页面上方这里就不贴出来了

**安装Docker前需要先下载相关的依赖**

1.  `sudo yum install -y yum-utils`
2.

sudo yum-config-manager \
        --add-repo \
        https://download.docker.com/linux/centos/docker-ce.repo

1.  `sudo yum install docker-ce docker-ce-cli containerd.io`
2.  `sudo systemctl start docker`

到这里docker已经成功安装！执行一下命令出现相关提示就算大功告成啦

**docker -v：查看docker版本  
docker images：查看docker容器中的镜像**  
最后我们来配置docker使用阿里云镜像加速，首先进入阿里云，找到如下

1.  `sudo mkdir -p /etc/docker`
2.  `sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://57ev31w4.mirror.aliyuncs.com"] } EOF`
3.  `sudo systemctl daemon-reload`
4.  `sudo systemctl restart docker`
