修改transmission-daemon用户

0. 说明 在debian安装了transmission-daemon后, 默认是以"debian-transmission"启动. 下载的文件也是属于该用户的. 这并不合我意, 需要改成使用我的用户启动.
1. 安装transmission

$ sudo apt-get install transmission-daemon
$ service transmission-daemon stop

2. 修改软件配置

$ sudo vi /etc/transmission-daemon/settings.json

{   # 下载配置
    "download-dir": "/media/repo/download",
    "download-limit": 100,
    "download-limit-enabled": 0,
    "download-queue-enabled": true,
    "download-queue-size": 5,
    # 远程安全配置
    "rpc-authentication-required": true,
    "rpc-bind-address": "0.0.0.0",
    "rpc-enabled": true,
    "rpc-password": "{f33f59e1ccabf6e50af23c94b8a144e7b95f5421U5l4f8jW",
    "rpc-port": 9091,
    "rpc-url": "/transmission/",
    "rpc-username": "transmission",
    "rpc-whitelist": "127.0.0.1",
    "rpc-whitelist-enabled": false
}

3. 修改启动配置

$ sudo vi /etc/init.d/transmission-daemon

# 修改USER变量为需要的用户名
USER=caspar

4. 修改文件权限

$ sudo chown USER:USERGROUP /media/repo/download
$ sudo chown USER:USERGROUP /etc/transmission-daemon/settings.json
$ sudo chown -R USER:USERGROUP /var/lib/transmission-daemon

5. 启动transmission

$ sudo service transmission-daemon start
