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 SupervisorSupervisor;
use SupervisorConnectorXmlRpc;
use fXmlRpcClient;
use fXmlRpcTransportHttpAdapterTransport;
use IvoryHttpAdapterGuzzle5HttpAdapter;
use SupervisorConfigurationConfiguration;
use SupervisorConfigurationSectionSupervisord;
use SupervisorConfigurationSectionProgram;
use IndigoIniRenderer;
//Create GuzzleHttp client
$guzzleClient = new GuzzleHttpClient(['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 . "rn";
}
try{
$supervisor->stopProcess('video_convert_02');
}
catch(Exception $e){
echo "rn 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 "rn Config rn" . $renderer->render($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: >我不明白为什么它会抛出异常,当我试图阻止这个过程时 解决方法
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 SupervisorApi('127.0.0.1',9001,'user','123');
$processes = $supervisor->getAllProcessInfo();
foreach ($processes as $processInfo) {
print_r($processInfo);
}
try {
$supervisor->stopProcess('video_convert_02');
}
catch (SupervisorApiException $e){
echo "rn Exception-> " . $e->getMessage();
}
