  • docker快速搭建远程桌面

    1. 主要命令

    # 第一次创建
    docker run -p 8080:80 --name mydestop dorowu/ubuntu-desktop-lxde-vnc
    # 保存
    docker commit $(docker ps -aq) mydestop:1.0; docker save -o mydestop.tar mydestop:1.0
    # 停止和删除所有的容器和镜像(用完之后, 可以执行该命令, 删除镜像, 以免影响速度和空间)
    docker stop $(docker ps -aq); docker rm $(docker ps -aq); docker rmi $(docker images -aq);
    # 导入本地桌面镜像, 并启动 (每次运行可以用该命令)
    docker load --input  mydestop.tar; docker run -p 8080:80 $(docker images -aq)
    # 导入本地桌面
    docker load --input  mydestop.tar;  
    # 后台运行任务
    nohup docker run -p 8080:80  $(docker images -aq) 2>&1 &
    # 删除后台运行
    ps ux
    kill -9 填写实际的进程pid号

    也可以让本地文件和docker镜像文件共享, 在https://github.com/codespaces 中可用下面命令

    # 直接运行任务
    docker run -p 8080:80 -it -v /workspaces:/root $(docker images -aq)
    # 后台运行任务
    nohup docker run -p 8080:80 -it -v /workspaces:/root $(docker images -aq) 2>&1 &

    如果8080端口被占用, 可以考虑换成别的端口, 只需把8080换成别的四位数即可.

    2. 搭建文件服务

    3. 查看电脑信息


    uname -a
    df -hl
    free -m
    lsb_release -a
    apt install screenfetch
    screenfetch -s

    4. python包的安装

    sudo apt update 
    sudo apt install python3-pip
    pip install numpy scipy matplotlib jupyter
