恩，装系统就不用说了吧，有个事情是树莓派默认32位系统，我用的4B还是建议装64位的，因为做其他用处的时候有的时候只有arm64版本的，32位的装不了。。。

apt-get换源

因为是64位的，需要选64位的源

大概的过程就是两个地方。
第一个

sudo nano /etc/apt/sources.list

改为

deb http://mirrors.tuna.tsinghua.edu.cn/debian buster main contrib non-free
deb http://mirrors.tuna.tsinghua.edu.cn/debian-security/ buster/updates main contrib non-free
deb http://mirrors.tuna.tsinghua.edu.cn/debian buster-updates main contrib non-free

第二个是/etc/apt/sources.list.d/raspi.list这里改为

deb http://mirrors.tuna.tsinghua.edu.cn/raspberrypi/ buster main ui

然后记得要sudo apt update和sudo apt upgrade

搭建Awtrix

大概是按照这个教程https://sakitami.github.io/posts/7968d939/

安装jdk

sudo apt install default-jdk

下载awtrix到树莓派

因为好像被墙了，我是下载到U盘上然后拷过去的
https://awtrixdocs.blueforcer.de/#/en-en/host
我下载到了这个位置/usr/local/awtrix

写service

首先sudo nano /etc/systemd/system/awtrix.service然后在里面写入

[Unit]
Description = AWTRIX Service
After network.target = awtrix.service

[Service]
Type = forking
WorkingDirectory =/usr/local/awtrix
ExecStart = /usr/local/bin/awtrix.sh start
ExecStop = /usr/local/bin/awtrix.sh stop
ExecReload = /usr/local/bin/awtrix.sh reload

[Install]
WantedBy=multi-user.target

然后创建sh文件，sudo nano /usr/local/bin/awtrix.sh

    SERVICE_NAME=awtrix
    PATH_TO_JAR=/usr/local/awtrix/awtrix.jar
    PID_PATH_NAME=/tmp/awtrix-pid
    case $1 in
        start)
            echo "Starting $SERVICE_NAME ..."
            if [ ! -f $PID_PATH_NAME ]; then
                sudo nohup java -jar $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
                            echo $! > $PID_PATH_NAME
                echo "$SERVICE_NAME started ..."
            else
                echo "$SERVICE_NAME is already running ..."
            fi
        ;;
        stop)
            if [ -f $PID_PATH_NAME ]; then
                PID=$(cat $PID_PATH_NAME);
                echo "$SERVICE_NAME stoping ..."
                kill $PID;
                echo "$SERVICE_NAME stopped ..."
                rm $PID_PATH_NAME
            else
                echo "$SERVICE_NAME is not running ..."
            fi
        ;;
        restart)
            if [ -f $PID_PATH_NAME ]; then
                PID=$(cat $PID_PATH_NAME);
                echo "$SERVICE_NAME stopping ...";
                kill $PID;
                echo "$SERVICE_NAME stopped ...";
                rm $PID_PATH_NAME
                echo "$SERVICE_NAME starting ..."
                sudo nohup java -jar $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
                            echo $! > $PID_PATH_NAME
                echo "$SERVICE_NAME started ..."
            else
                echo "$SERVICE_NAME is not running ..."
            fi
        ;;
    esac

老实说上面这部分我没有很看懂，大概就是运行那个jar文件吧。然后加权限sudo chmod +x /usr/local/bin/awtrix.sh，起服务sudo systemctl enable awtrix.service和sudo systemctl start awtrix.service

测试

打开设备的ip地址，端口号7000，应该可以看到后台界面了
