In http:\/\/ouyangminwei.com\/index.php\/2021\/09\/18\/build-a-discrod-music-bot\/<\/a>, I created a discord bot and develop on a Raspberry pi, but now there are two problems<\/p>\n\n\n\n

  1. The network used by is a floating IP.<\/li>
  2. Even if I can SSH in, I still can’t see or close the discord bot since It is on a terminal.<\/li><\/ol>\n\n\n\n

    Ngrok<\/h1>\n\n\n\n

    After searching a little bit, I found that ngrok can solve the first problem perfectly.<\/p>\n\n\n\n

    Ngrok is a cross-platform application that exposes local server ports to the Internet, so I can expose my raspberry pi to the internet.<\/p>\n\n\n\n

    First, sign up and download ngrok on this website https:\/\/ngrok.com\/<\/a>.<\/p>\n\n\n\n

    Because it runs on the Raspberry Pi, so download the 32-Bit ARM’s version<\/p>\n\n\n\n

    \"\u9019\u5f35\u5716\u7247\u7684<\/figure>\n\n\n\n

    After you download the ngrok upzip<\/strong> it.<\/p>\n\n\n\n

    unzip ngrok-stable-linux-arm.zip.zip<\/code><\/pre>\n\n\n\n
    \"\u9019\u5f35\u5716\u7247\u7684<\/figure>\n\n\n\n
    Login the ngrok, yo can get your Authtoken<\/p>\n\n\n\n
    .\/ngrok authtoken<\/code><\/pre>\n\n\n\n
    \"\u9019\u5f35\u5716\u7247\u7684<\/figure>\n\n\n\n
    And you are ready to fire it up.<\/p>\n\n\n\n
    .\/ngrok tcp 22<\/code><\/pre>\n\n\n\n
    \"\u89e3\u6790Ngrok<\/figure>\n\n\n\n
    remember the Ip it gives  you<\/p>\n\n\n\n
    tcp:\/\/2.tcp.ngrok.io:14139<\/code><\/pre>\n\n\n\n
    Then you can SSH to it<\/p>\n\n\n\n
    ssh username@2.tcp.ngrok.io -p14139<\/code><\/pre>\n\n\n\n
    \"\u9019\u5f35\u5716\u7247\u7684<\/figure>\n\n\n\n
    Screen<\/h1>\n\n\n\n
    In order to access to running terminal, we can use “screen” to achieve it<\/p>\n\n\n\n
    sudo apt-get install screen<\/code><\/pre>\n\n\n\n
    \"\u9019\u5f35\u5716\u7247\u7684<\/figure>\n\n\n\n
    This can create a new screen call “bot”<\/p>\n\n\n\n
    screen -mS bot<\/code><\/pre>\n\n\n\n
    And you can start your server, for here, I will test will python httpserver<\/p>\n\n\n\n
    python -m SimpleHTTPServer<\/code><\/pre>\n\n\n\n
    \"\u9019\u5f35\u5716\u7247\u7684<\/figure>\n\n\n\n
    Now, the server is running, CTRL+A and then CTRL+D to detach the screen.<\/p>\n\n\n\n
    screen -ls<\/code><\/pre>\n\n\n\n
    Show the screen <\/p>\n\n\n\n
    \"\u9019\u5f35\u5716\u7247\u7684<\/figure>\n\n\n\n
    I have a “test.root” over here, Try to see if I can download this file via this python http server<\/p>\n\n\n\n
    \"\u9019\u5f35\u5716\u7247\u7684<\/figure>\n\n\n\n
    wget 127.0.0.1:8000\/test.root<\/code><\/pre>\n\n\n\n
    \"\u9019\u5f35\u5716\u7247\u7684<\/figure>\n\n\n\n
    Every works well,  the server it still running.<\/p>\n\n\n\n
    screen -x bot<\/code><\/pre>\n\n\n\n
    Back to the terminal<\/p>\n\n\n\n
    \"\u9019\u5f35\u5716\u7247\u7684<\/figure>\n\n\n\n
    So now, I can access the Raspberry pi with ngrok and use screen to control the terimal.<\/p>\n\n\n\n
