如何通过PHP脚本在Linux中进行进程管理

$command = "/usr/bin/php /path/to/my_process.php";
exec("nohup $command >/dev/null 2>&1 & echo $!", $output);
$pid = (int) $output[0];

$command = "kill $pid";
exec($command);

$command = "ps aux | grep my_process.php";
exec($command, $output);

<?php
$action = $argv[1]; // 从命令行参数获取要执行的操作

if ($action == "start") {
    $command = "/usr/bin/php /path/to/my_process.php";
    exec("nohup $command >/dev/null 2>&1 & echo $!", $output);
    $pid = (int) $output[0];
    echo "Process started. PID: $pid
";
} elseif ($action == "stop") {
    $pid = (int) $argv[2]; // 从命令行参数获取要停止的进程的PID号
    $command = "kill $pid";
    exec($command);
    echo "Process stopped. PID: $pid
";
} elseif ($action == "status") {
    $command = "ps aux | grep my_process.php";
    exec($command, $output);
    echo implode("
", $output) . "
";
} else {
    echo "Invalid action.
";
}
