我正在尝试在Debian中启动一个PHP脚本作为守护进程。我也希望它也能在启动时启动。
我一直在使用/path/to/php /path/to/script/Insert.php &而没有问题，也可以shell_exec("nohup /path/to/php /path/to/script/Insert.php >/dev/null &")。我尝试使用下面的脚本，但它不会使脚本进入运行状态。
将文件复制到/etc/init.d/并使用update-rc.d没有问题。我可以使用service congen-insert start来启动＆＃39;脚本，但它似乎并没有真正运行，它也没有开始做任何工作。
我错过了什么，或者我在哪里弄错了脚本？
我知道有几种方法可以解决这个问题，但我真的只是想了解我做错了什么，或者为什么我做的不起作用。
非常感谢任何帮助或建议！如果您需要其他任何内容或我在描述中遗漏的任何内容，请告诉我，以便我能够更正。
提前致谢。

问题在于重定向输出。我还修改了带有bash标头的php文件，因此它不会显示为顶部的多个php进程，而是显示文件名：
修订后的服务脚本：

修改PHP脚本以运行：
#!/php52/php-5.6.6/bin/php
<?php
const LoaderPath = __DIR__ . DIRECTORY_SEPARATOR . ".." . DIRECTORY_SEPARATOR . "includes.php";
require_once LoaderPath;
use PhpAmqpLib\Channel\AMQPChannel;
use PhpAmqpLib\Message\AMQPMessage;
use requests\InsertRequest;
$connection = GetRabbitConnection();
$channel = $connection->channel();
$RedisClient = GetRedisClient();
DeclareQueues($connection, $RedisClient);
$InsertExchange = $RedisClient->get(Insert.":".Exchange);
$InsertQueue = $RedisClient->get(Insert.":".Queue);
$Prefetch = $RedisClient->get(Insert.":".Prefetch);
$RedisClient->disconnect();
$RedisClient = null;
$mysql= ConnectionBuilder::GetMySQLi();
$channel->basic_qos(0,$Prefetch,false);
$channel->basic_consume($InsertQueue, $InsertExchange, false, false, false, false, "callback");
echo "Consuming on Exchange $InsertExchange with Queue $InsertQueue\n";
while(true) {
$channel->wait();
}
$channel->close();
function callback(AMQPMessage $message){
global $mysql;
echo "Message received", "\n";
$InsertRequest = new InsertRequest($message->body);
echo "Running Insert Statement\n";
if (!$mysql->query($InsertRequest->SQL)){
echo "Error: ".$mysql->error;
}
/** @type AMQPChannel $channel */
$channel = $message->delivery_info['channel'];
$channel->basic_ack($message->delivery_info['delivery_tag']);
echo "Insert Complete\n";
}
将文件添加到/etc/init.d/并使php脚本和服务脚本都可执行后，我可以使用service congen-insert start启动服务并使用其他命令，就像任何其他init.d服务一样
应该注意的是，我将控制台重定向到/dev/null，但您也可以通过用可写路径替换/dev/null来重定向到文件。
对来自another SO post“2>&1引用的2的解释是stderr的流编号（错误消息），1代表 [sic] < / em> stdout流（标准的非错误输出流）。“因此，我基本上将stdout重定向到/dev/null并将stderr重定向到stdout

使用交互式shell命令编写脚本来执行php脚本，如php from terminal示例所示。这仅适用于PHP编译为包含--with-readline选项
设置一个cron任务（linux任务调度程序）来运行此脚本，如cron setup示例所示。
