在家里闷久了想追剧，把吃灰的树莓派 3b+ 折腾出来，一顿操作猛如虎，无奈网速2K5，反正功耗低，慢慢下吧。。。

OSMC

之所以选OSMC，是因为LibreELEC精简的比较厉害，后面装Aria2的时候要补很多包。
直接去OSMC官网，下载image或者用安装程序创建启动U盘（现在没有linux版安装程序了，xp版一样好用）
OSMC 默认源速度还行，也可以换阿里源，不过我遇到更新源的时候包校验失败的问题，又换回默认源了

Aria2

apt-get安装Aria2

sudo apt install -y aria2
mkdir -p ~/.config/aria2/ && vi ~/.config/aria2/aria2.config
配置文件如下：

daemon=true
rpc-secret=secret 
enable-rpc=true   
rpc-allow-origin-all=true
rpc-listen-all=true                               
rpc-listen-port=6800                             
max-concurrent-downloads=10
continue=true             
max-connection-per-server=1
min-split-size=10M       
split=10                 
max-overall-download-limit=0
max-download-limit=0       
max-overall-upload-limit=0 
max-upload-limit=0       
dir=/home/osmc/Download
file-allocation=prealloc
check-certificate=false
save-session=/home/osmc/.config/aria2/aria2.session
input-file=/home/osmc/.config/aria2/aria2.session 
save-session-interval=60                         
disable-ipv6=true                               
bt-tracker=udp://188.241.58.209:6969/announce

设置自启动服务

sudo vi /etc/systemd/system/aria2.service

[Unit]
Description=Aria2 Service
After=network.target
[Service]
User=osmc
Type=forking
ExecStart=/usr/bin/aria2c --conf-path=/home/osmc/.config/aria2/aria2.confi
[Install]
WantedBy=multi-user.target

shell脚本更新bt-tracker

vi /home/osmc/aria2-trackers.sh

echo "Start"
tracker=$(curl https://ngosang.github.io/trackerslist/trackers_best_ip.txt | grep '://' | paste -sd ";" - | awk '{print "bt-tracker="$1}')
echo $tracker
##这里的32s是指bt-tracker所在的aira2.config第32行
sed -i "32s#.*#$tracker#" ~/.config/aria2/aria2.config
echo "Done, run below cmd to restart aria2"
echo "sudo systemctl restart aria2"
sudo systemctl restart aria2

AriaNg

下载AriaNg，交给OSMC来启动
sudo cp ./AriaNg/ /usr/share/kodi/addons/webinterface.default/ariang
