通过PHP API动态更改管理程序进程

2019年7月27日 85次阅读

我设置了 Supervisor,用于管理我的工作流程.

现在,我想通过使用PHP API动态更改进程(停止某些进程并启动新进程).

我发现这个library似乎对我正在尝试的东西很有用.具体来说,我使用this更改配置,使用this管理主管.

我已设置此库并具有以下示例代码,似乎运行良好(从here和here)

<?php    

require './vendor/autoload.php';
use Supervisor\Supervisor;
use Supervisor\Connector\XmlRpc;
use fXmlRpc\Client;
use fXmlRpc\Transport\HttpAdapterTransport;
use Ivory\HttpAdapter\Guzzle5HttpAdapter;

use Supervisor\Configuration\Configuration;
use Supervisor\Configuration\Section\Supervisord;
use Supervisor\Configuration\Section\Program;
use Indigo\Ini\Renderer;


//Create GuzzleHttp client
$guzzleClient = new \GuzzleHttp\Client(['auth' => ['user', '123']]);

// Pass the url and the guzzle client to the XmlRpc Client
$client = new Client(
    'http://127.0.0.1:9001/RPC2',
    new HttpAdapterTransport(new Guzzle5HttpAdapter($guzzleClient))
);

// Pass the client to the connector
// See the full list of connectors bellow
$connector = new XmlRpc($client);

$supervisor = new Supervisor($connector);

$processes = $supervisor->getAllProcesses();

foreach ($processes as $key => $processInfo) {
    echo $processInfo . "\r\n";
}

try{
$supervisor->stopProcess('video_convert_02');
}
catch(Exception $e){
    echo "\r\n Exception-> " . $e->getMessage();
}


$config = new Configuration;
$renderer = new Renderer;

$section = new Supervisord(['identifier' => 'supervisor']);
$config->addSection($section);

$section = new Program('test', ['command' => 'cat']);
$config->addSection($section);

echo "\r\n Config \r\n" . $renderer->render($config->toArray());

//Not sure how to use this config information to launch supervisor processes.

?>

输出如下：

pdf_convert_00
pdf_convert_01
video_convert_00
video_convert_01
video_convert_02
video_convert_03

 Exception-> BAD_NAME: video_convert_02
 Config
[supervisord]
identifier = supervisor

[program:test]
command = cat

我这里有两个问题：

最佳答案 我没有使用此库,但“BAD_NAME”错误表示您的配置中没有此名称的此类进程.

顺便说一句,如果您只需要调用Supervisor API,您可以使用SupervisorXMLRPC library.这只是将您的请求转发给主管.

$supervisor = new \Supervisor\Api('127.0.0.1', 9001, 'user', '123');

$processes = $supervisor->getAllProcessInfo();
foreach ($processes as $processInfo) {
    print_r($processInfo);
}

try {
    $supervisor->stopProcess('video_convert_02');
}
catch (\Supervisor\ApiException $e){
    echo "\r\n Exception-> " . $e->getMessage();
}
