我下载的是docker-26.1.4.tgz版本
解压压缩包并把文件放在/usr/bin/
tar -zxvf docker-26.1.4.tgz
sudo cp docker/* /usr/bin/ 新增用户组 docker。其他用户需要有docker的执行权限只需将用户加入docker用户组即可
$ sudo groupadd docker
$ sudo usermod -aG docker $USER编写docker.service文件放到目录/etc/systemd/system

启动docker service,并设置开机自启动
$ sudo chmod x /etc/systemd/system/docker.service
$ sudo systemctl daemon-reload
$ sudo systemctl start docker
$ sudo systemctl enable docker验证 sudo systemctl status docker 使用docker ps命令报错
[appadminiomapp ~]$ docker ps
permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.45/containers/json: dial unix /var/run/docker.sock: connect: permission denied
检查是否将用户加入docker用户组并且需要重新登录用户才能生效。 保存镜像进行打包在另一台服务上使用
docker save -o nginx_latestx86.tar nginx:lastest
在另一台服务器上docker加载tar包
docker load -i nginx_latestx86.tar 测试启动nginx镜像但是启动后访问nginx无反应参考 Docker解决宿主机无法访问docker容器中nginx服务-CSDN博客
