我正在尝试在 Debian 中启动一个 php 脚本作为守护进程。我也希望它能够在启动时启动。
我已经开始使用 /path/to/php/path/to/script/Insert.php &
没有问题,并且可以 shell_exec("nohup/path/to/php/path/to/script/Insert.php >/dev/null &")
也是如此。我已尝试使用以下脚本,但它不会使脚本进入操作状态。
正在将文件复制到 /etc/init.d/
并使用 update-rc.d
,没有出现问题。我可以使用 service congen-insert start
来“启动”脚本,但它似乎并未实际运行,也没有开始执行任何工作。
我错过了什么,或者我的脚本哪里出了问题?
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,或者为什么我所做的不起作用。
非常感谢任何帮助或建议!如果您还有其他需要,或者我的描述中遗漏了任何内容,请告诉我,以便我进行更正。
提前致谢。

我尝试运行的脚本:

require_once LoaderPath;
use PhpAmqpLib\Channel\AMQPChannel;
use PhpAmqpLib\Message\AMQPMessage;
use requests\InsertRequest;
$connection = GetRabbitConnection();
$channel = $connection->channel();
$RedisClient = GetRedisClient();
DeclareQueues($connection, $RedisClient);
$MySQLHost = $RedisClient->get(MySQLHostKey);
$MySQLUser = $RedisClient->get(MySQLUserKey);
$MySQLPassword = $RedisClient->get(MySQLPasswordKey);
$MySQLDatabase = $RedisClient->get(MySQLDatabaseKey);
$InsertExchange = $RedisClient->get(Insert.":".Exchange);
$InsertQueue = $RedisClient->get(Insert.":".Queue);
$Prefetch = $RedisClient->get(Insert.":".Prefetch);
$RedisClient->disconnect();
$RedisClient = null;
$mysql= new mysqli($MySQLHost, $MySQLUser, $MySQLPassword, $MySQLDatabase);
$channel->basic_qos(0,$Prefetch,false);
$channel->basic_consume($InsertQueue, $InsertExchange, false, false, false, false, "callback");
echo "Consuming on Exchange $InsertExchange with Queue $InsertQueue\n";
while(true) {

$channel->close();
function callback(AMQPMessage $message){

$InsertRequest = new InsertRequest($message->body);

if (!$mysql->query($InsertRequest->SQL)){

/** @type AMQPChannel $channel */
$channel = $message->delivery_info['channel'];
$channel->basic_ack($message->delivery_info['delivery_tag']);
echo "Insert Complete\n";
}
最佳答案
问题出在输出的重定向上。我还使用 bash 的 header 修改了 php 文件,因此它不会在顶部显示为多个 php 进程,而是显示文件名:
修改后的服务脚本:

N=/etc/init.d/$NAME
echo "Usage: $N {start|stop|restart|force-reload}" >&2
exit 1
;;

exit 0
修改后的 PHP 脚本运行:
#!/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 脚本和服务脚本可执行后,我可以使用 service congen-insert start
启动服务> 并像任何其他 init.d 服务一样使用其余命令。
应该注意的是,我将控制台重定向到 /dev/null
,但您也可以通过将 /dev/null
替换为重定向到文件可写路径。
对 another SO post 引用的 2>&1
的解释“2
是 stderr(错误消息)的流编号,1
表示 stdout 流(标准非错误输出)溪流)。”因此,我实质上是将 stdout
重定向到 /dev/null
并将 stderr
重定向到 stdout
