树莓派搭建BT下载器

更新树莓派：
sudo apt-get install update
安装transmission：
sudo apt-get install transmission-daemon
给用户授权：
sudo usermod -a -G pi debian-transmission
设置Transmission的配置文件：
sudo nano /etc/transmission-daemon/settings.json

在这个配置文件中有很多可以更改的选项，对应着上面的配置文件说几个重点的部分，方便理解和自行修改。

blocklist参考了techjawab的github：

"blocklist-url": "http://list.iblocklist.com/?list=ydxerpxkpcfqjaybcssw&fileformat=p2p&archiveformat=gz",

设置下载目录为用户目录下的Downloads文件夹：

"download-dir": "/home/pi/Downloads",

设置未下载完成数据存放地点为Downloads文件夹：

"incomplete-dir": "/home/pi/Downloads",

设置Web登陆密码为：raspberry

"rpc-password": "raspberry",

设置Web登陆用户名：transmission

"rpc-username": "transmission",

允许Web登陆：（设置为true）

"utp-enabled": true

设置完成之后，保存setting.json文件，重新启动transmission服务：

sudo service transmission-daemon reload

到这里可以在浏览器中输入你的树莓派的ip地址和端口号放完transmission的web界面了，比如你的树莓派地址是：192.168.1.10，那么在浏览器中输入：

192.168.1.10:9091

登陆的用户名和密码使用配置文件中设置的内容，例子中的用户名是：transmission，密码是：raspberry。

如果遇到permission问题，按照文中的下载地址，使用以下命令提升Downloads目录的权限：

sudo chmod 777 -R /home/pi/Downloads/

登陆到Web界面之后，点击左上角的文件夹图标可以添加种子文件，树莓派就会开始下载了。
