新貴ReactPHP腳本-AWS EC2 ElasticbeanStalk

Question

我有一個使用ReactPHP Loop和HTTPServer在永無休止的循環中運行的php腳本

現在，我正在使用一個AWS Elastic Beanstalk Worker，它讀取一個SQS隊列，為此端口80上需要HTTPServer。 這是我的PHP腳本：

<?php

/* loading the base configuration files and defines */
require_once 'base/bootstrap.php';

$loop   = React\EventLoop\Factory::create();
$socket = new React\Socket\Server($loop);
$http   = new React\Http\Server($socket);

$i = 0;
$j = 0;

$api = BaseClass::initiate(); // the initially loaded class setting up the environment

/**
 * The $loop React Event Loop will make sure that $api BaseClass required to be alive
 * is up-to-date managing the Environment
 */
$loop->addPeriodicTimer(3, function ($timer) use (&$i, &$j, $loop, &$api) {
    try {

        if ($i >= rand(300, 400)) {
            /* Refresh the Environment if any DB changes happen, like new clients added, etc. */
            $api = BaseClass::initiate();
        }

        /**
         * I Do my Work Here
         */

    } catch (Exception $e) {
        /**
         * Error Handling
         */
    }
    $i++;
    $j++;
});

/**
 * The $http React HTTP Server will listen to the SQS Queue and perform actions accordingly
 */
$http->on('request', function (React\Http\Request $request, React\Http\Response $response) use (&$api) {
    $request->on('data', function ($data) use (&$api, $request, $response) {
        try {
            $postData = json_decode($data, TRUE);

            /**
             * I process the Post Data here using $api loaded Class
             */

        } Catch (Exception $e) {
            /* Send an Error Message to the Queue */
            /**
             * Error Handling
             */
        }
    });
});

$socket->listen(80);
$loop->run();

我查看此結構的原因是$ api打開套接字連接，並且需要$ http Server才能運行。

nohup php /var/app/current/server.php &正常工作，但是，我正在尋找創建一個暴發戶服務

我的UpStart腳本在/etc/init/myscript.conf中如下所示

#Info
start on startup
stop on shutdown
respawn
php /var/app/current/server.php

這不起作用。 不知道，我要去哪里錯了。

有什么建議么？

用這個替換您的/etc/init/myscript.conf

# Info
description "myscript name"
author      "Yourself"

# Events
start on startup
stop on shutdown

# Automatically respawn
respawn
respawn limit 20 5

# Run the script!
# Note, in this example, if your PHP script returns
# the string "ERROR", the daemon will stop itself.
script
    [ $(exec /usr/bin/php -f /var/app/current/server.php) = 'ERROR' ] && ( stop; exit 1; )
end script

然后開始

sudo service myscript start
