先安装smartmontools，以管理员运行，不然不能正常开启smart，可使用smtp发送邮件。

windows获取硬盘健康状态

发布时间：April 15, 2018 // 分类： // No Comments

wmic diskdrive get status,deviceid,model

也可使用smartctl windows版查看：
列出硬盘列表：

smartctl --scan
/dev/sda -d ata # /dev/sda, ATA device
/dev/sdb -d ata # /dev/sdb, ATA device
/dev/sdc -d ata # /dev/sdc, ATA device
/dev/sdd -d ata # /dev/sdd, ATA device
/dev/sde -d ata # /dev/sde, ATA device

查看是否开启smart：

smartctl -i /dev/sda

php使用rpc xml管理rtorrent

发布时间：April 3, 2018 // 分类： // No Comments

rtorrent开启rpc：

scgi_port = 127.0.0.1:5000

通过nginx中转rpc请求：

server {
    listen 8000;
    server_name localhost;
    location ^~ /RPC2 {
        include scgi_params;
        scgi_pass   127.0.0.1:5000;
    }
}

php需安装xmlrpc扩展：

<?php
class XMLRPCClient
{
  public function __construct($uri)
  {
    $this->uri = $uri;
    $this->ch = null;
  }

  public function __destruct()
  {
    $this->close();
  }

  public function close()
  {
    if ($this->ch !== null)
    {
      curl_close($this->ch);
    }
    $this->ch = null;
  }

  public function get($method, $params = array())
  {
    $xml = xmlrpc_encode_request($method,$params);
    if ($this->ch === null)
    {
      $this->ch = curl_init();
      curl_setopt($this->ch, CURLOPT_URL, $this->uri);
      curl_setopt($this->ch, CURLOPT_HEADER, 0); 
      curl_setopt($this->ch, CURLOPT_RETURNTRANSFER, true);
      curl_setopt($this->ch, CURLOPT_POST, true);
    }
    curl_setopt($this->ch, CURLOPT_POSTFIELDS, $xml);
    $response = curl_exec($this->ch);
    $response = str_replace('i8>', 'string>', $response);
    $result = xmlrpc_decode_request($response, $method);
    return $result;
  }
}

$client = new XMLRPCClient("http://127.0.0.1:8000/RPC2");
//查看rpc命令列表
var_dump($client->get("system.listMethods"));
//查看任务列表
$list = $client->get("download_list", array("","started"));
//文件路径
$filepath = $client->get("d.get_base_path", $list[0]);
//上传速度
$up_rate = $client->get("d.get_up_rate", $list[0]);
$down_rate = $client->get("d.get_down_rate", $list[0]);
echo $up_rate.'/'.$down_rate.PHP_EOL;
//删除下载
//$client->get("d.erase", $list[0]);
//删除文件
//unlink($filepath);
