手上有VPS的想刷PT的朋友可以看看，但是如果你的硬盘空间不到50G的话，很有可能会爆仓，今天给大家分享一个教程，可以自动刷PT流量的同时还可以自动删除种子。
Transmission安装
脚本：
| 12 | wget http://github.itzmx.com/1265578519/transmission/master/2.84/transmissionbt.sh -O transmissionbt.shsh transmissionbt.sh |
访问地址为http://IP:9091，默认用户名和密码均为itzmx.com，文件下载位置:/home/transmission/Downloads/
如需修改配置，需要先暂停服务，否则修改无效。
service transmissiond stop vi /home/transmission/.config/transmission/settings.json| 12 | service transmissiond stopvi /home/transmission/.config/transmission/settings.json |
rpc-username 帐号
rpc-password 密码
rpc-port 端口
rpc-authentication-required 是否开启使用账号密码加密访问
preallocation 需要设置为0，这是这个办法中不会爆盘的关键。
启动Transmission服务：
service transmissiond start| 1 | service transmissiond start |
如需卸载Transmission：
service transmissiond stop rm -rf /home/transmission rm -rf /usr/share/transmission| 123 | service transmissiond stoprm -rf /home/transmissionrm -rf /usr/share/transmission |
FlexGet安装
这是一个扩展工具，可以令Transmission具备RSS下载的功能，其实也能自动删除种子（但是我的情况比较特殊，VPS硬盘比较小，用FlexGet的clean_transmission和free_space插件会有问题）。
安装编译环境：
yum install -y gcc make zlib zlib-devel readline-devel sqlite sqlite-devel openssl-devel mysql-devel gd-devel| 1 | yum install -y gcc make zlib zlib-devel readline-devel sqlite sqlite-devel openssl-devel mysql-devel gd-devel |
安装 Python（一般的VPS系统都自带，有能力自行修改后面代码的可以不安装）：
wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz tar zxf Python-2.7.13.tgz pushd Python-2.7.13 ./configure --prefix=/root/python && \ make && \ make install && \ ln -s /root/python/bin/python2.7 /usr/local/bin/python source ~/.bash_profile popd| 123456789 | wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgztar zxf Python-2.7.13.tgzpushd Python-2.7.13./configure --prefix=/root/python && \make && \make install && \ln -s /root/python/bin/python2.7 /usr/local/bin/pythonsource ~/.bash_profilepopd |
安装 pip：
wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate /usr/local/bin/python get-pip.py ln -s /root/python/bin/pip /usr/local/bin/pip| 123 | wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate/usr/local/bin/python get-pip.pyln -s /root/python/bin/pip /usr/local/bin/pip |
安装 virtualenv：
/usr/local/bin/pip install virtualenv ln -s /root/python/bin/virtualenv /usr/local/bin/virtualenv| 12 | /usr/local/bin/pip install virtualenvln -s /root/python/bin/virtualenv /usr/local/bin/virtualenv |
安装 FlexGet：
cd /root/ virtualenv /root/flexget/ /root/flexget/bin/pip install flexget /root/flexget/bin/pip install transmissionrpc| 1234 | cd /root/virtualenv /root/flexget//root/flexget/bin/pip install flexget/root/flexget/bin/pip install transmissionrpc |
添加FlexGet配置文件：
vi /root/flexget/config.yml| 1 | vi /root/flexget/config.yml |
配置文件示例：
tasks: mt: rss: https://tp.m-team.cc/torrentrss.php?https=1&rows=10&cat410=1&cat429=1&cat424=1&cat430=1&icat=1&isize=1&iuplder=1&linktype=dl&passkey=***** accept_all: yes content_size: min: 256 max: 3072 download: /home/transmission/torrent transmission: host: 127.0.0.1 port: 9091 username: user password: password| 12345678910111213 | tasks: mt: rss: https://tp.m-team.cc/torrentrss.php?https=1&rows=10&cat410=1&cat429=1&cat424=1&cat430=1&icat=1&isize=1&iuplder=1&linktype=dl&passkey=***** accept_all: yes content_size: min: 256 max: 3072 download: /home/transmission/torrent transmission: host: 127.0.0.1 port: 9091 username: user password: password |
这个示例是我看到的教程中给的，其原文还给了clean_transmission和free_space两个插件的配置，附在上面的配置后面即可。
clean_transmission: host: 127.0.0.1 port: 9091 username: user password: password finished_for: 6 hours tracker: tp.m-team.cc delete_files: Yes free_space: path: /home/transmission/Downloads space: 3072| 1234567891011 | clean_transmission: host: 127.0.0.1 port: 9091 username: user password: password finished_for: 6 hours tracker: tp.m-team.cc delete_files: Yes free_space: path: /home/transmission/Downloads space: 3072 |
但是我并没有使用这两个插件，原作者可能没有我这样小硬盘的VPS。这两个插件的意思是，种子下载完成以后6个小时自动删除，当硬盘剩余空间小于3G时，不再自动添加种子。但是我的使用中，当剩余空间不足3G时，确实不会添加新的种子了，但是这个时候“6小时自动删除”的设置却也无效了，因为free_space的优先级很高，检测到空间不足时，就会退出任务，clean_transmission插件的任务不再执行了。所以用这个办法还是得偶尔查看一下Transmission，当然如果你的硬盘足够大，应该是不需要考虑这个问题的，这个配置可以使用。
注意：使用这个的话，Transmission的preallocation需要设置为1。
先创建torrent下载的目录：
mkdir /home/transmission/torrent| 1 | mkdir /home/transmission/torrent |
执行FlexGet：
/root/flexget/bin/flexget -c /root/flexget/config.yml execute| 1 | /root/flexget/bin/flexget -c /root/flexget/config.yml execute |
可以添加一个定时任务：
crontab -e| 1 | crontab -e |
在其中加入：
*/5 * * * * /root/flexget/bin/flexget -c /root/flexget/config.yml execute| 1 | */5 * * * * /root/flexget/bin/flexget -c /root/flexget/config.yml execute |
意思是，每5分钟执行一次。
自动清理种子脚本
自动清理种子的任务我交给了另外一个脚本来执行。
新建脚本文件：
vi /root/trans_cleanup.sh| 1 | vi /root/trans_cleanup.sh |

修改好其中的用户名、密码、Transmission下载目录和硬盘最大使用的百分比（DISK_USED_MAX=”90″）。
定时任务（crontab -e）中添加：
*/1 * * * * /bin/bash /root/trans_cleanup.sh| 1 | */1 * * * * /bin/bash /root/trans_cleanup.sh |
每分钟执行一次。
注意事项
1、因为Transmission下载时，没有预分配磁盘空间，因此硬盘是一点一点占用的，只要达到了设置的阈值（比如90%），这个脚本就会清理已经完成的种子，如果空间还不够，就会清理正在下载的种子。因为脚本是每分钟执行的，所以没有硬盘塞满的风险。
2、硬盘总空间太小，就会经常需要删除旧的种子，这样一个种子的分享率可能就不高，长久下来，PT网站的总分享率也就不高了，可以通过调节接收种子的最大体积来影响（FlexGet配置文件中的3072表示最大接受3G的种子，超过就会被过滤，不会添加到Transmission中）。
3、Debian和Ubuntu应该也是可以使用的，只需要自己安装好Transmission和FlexGet就行。
4、如果重启后，transmission web ui无法连接，可能是centos默认的firewall防火墙的问题，关闭即可。
