See docker run --help.判断为网络连接问题或者是镜像资源访问受限。编辑Docker的配置文件/etc/docker/daemon.jsonvi /etc/docker/daemon.json添加或修改如下内容以使用国内的镜像加速器{ runtimes: { nvidia: { args: [], path: nvidia-container-runtime } }, registry-mirrors: [ https://docker.registry.cyou, https://docker-cf.registry.cyou, https://dockercf.jsdelivr.fyi, https://docker.jsdelivr.fyi, https://dockertest.jsdelivr.fyi, https://mirror.aliyuncs.com, https://dockerproxy.com, https://mirror.baidubce.com, https://docker.m.daocloud.io, https://docker.nju.edu.cn, https://docker.mirrors.sjtug.sjtu.edu.cn, https://docker.mirrors.ustc.edu.cn, https://mirror.iscas.ac.cn, https://docker.rainbond.cc ] }使配置文件生效sudo systemctl daemon-reload重启docker服务sudo systemctl restart docker检查docker配置信息docker info | grep Registry看到镜像列表则正常重新下载mysql数据库docker run -d \ --name mysql \ -p 3306:3306 \ -e TZAsia/Shanghai \ -e MYSQL_ROOT_PASSWORD123 \ mysql
