二、离线安装Docker

1）将下载的包上传到服务器上去

2）安装docker

[root@web02 ~]# tar -xzvf docker-19.03.9.tgz
[root@web02 ~]# cp docker/* /usr/bin/
[root@web02 ~]# cat >/usr/lib/systemd/system/docker.service <<EOF

3) 启动docker

[root@web02 ~]# systemctl start docker
[root@web02 ~]# systemctl enable docker

4）配置加速器

[root@web02 ~]# cat > /etc/docker/daemon.json <<EOF

[root@web02 ~]# systemctl daemon-reload
[root@web02 ~]# systemctl restart docker

三、安装云桌面镜像

[root@web02 ~]# docker pull swr.cn-north-1.myhuaweicloud.com/iivey/linux-desk:v1.0

四、启动云桌面

方式一：docker命令直接运行

[root@web02 ~]# docker run -itd --shm-size 4G -p 6080:6080 -e VNC_PASSWD=admin123456 -e GEOMETRY='1366x768' -e DEPTH=32 -v /data/Downloads:/root/Downloads/ -v /data/Documents:/root/Documents -v /data/Pictures:/root/Pictures -v /data/Videos:/root/Videos -v /data/Desktop:/root/Desktop --restart unless-stopped --name linuxdesk swr.cn-north-1.myhuaweicloud.com/iivey/linux-desk:v1.0

方式二：docker-compose方式

如果用docker-compose方式启动，docker-compose的官网：Releases · docker/compose

本文章使用的是版本为1.16.1，百度网盘下载链接：百度网盘请输入提取码提取码: sdc5

docker-compose.yml文件内容如下：

version: '2.3'
