【问题分析】

1. 查看docker配置文件
   1. sudo cat /etc/docker/daemon.json
   2. 
   3. 配置文件开头stry-mirrors 错误
      1. 少了 { 
      2. stry-mirrors 应该是 registry-mirrors

【解决办法】

1. 删除docker配置文件
   1. sudo rm /etc/docker/daemon.json
   2. 
2. 启动docker
   1. sudo systemctl start docker
   2. 
3. 编辑配置文件
   1. sudo vi /etc/docker/daemon.json
   2. 
   3. 配置一下内容

   4. {"registry-mirrors": ["https://mirror.ccs.tencentyun.com","http://hub-mirror.c.163.com",
      "https://e2zfh98i.mirror.aliyuncs.com","https://mirror.baidubce.com","https://docker.mirrors.ustc.edu.cn","https://docker-cf.registry.cyou","https://dockercf.jsdelivr.fyi","https://docker.jsdelivr.fyi","https://dockertest.jsdelivr.fyi","https://dockerproxy.com","https://docker.m.daocloud.io","https://docker.nju.edu.cn","https://docker.mirrors.sjtug.sjtu.edu.cn","https://mirror.iscas.ac.cn","https://docker.rainbond.cc","https://do.nark.eu.org","https://dc.j8.work","https://dockerproxy.com","https://gst6rzl9.mirror.aliyuncs.com","https://registry.docker-cn.com","http://hub-mirror.c.163.com","http://mirrors.ustc.edu.cn/","https://mirrors.tuna.tsinghua.edu.cn/","http://mirrors.sohu.com/"]
      }
      

   5. 

4. 刷新配置内容

   1.  sudo systemctl daemon-reload

   2. 

【运行结果】

1. 启动docker
2. sudo systemctl restart docker
3. 
4. 查看docker启动状态
   1. sudo systemctl status docker
   2. 
5. 尝试下载镜像
   1. docker pull tomcat
   2. 
   3. 可以看到可以正常的下载
   4.
