本篇文章给大家带来的内容是关于基于laravel框架下使用守护进程supervisor实现定时任务（毫秒），有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。
公司需要实现X分钟内每隔Y秒轮训某个接口，Linux自带的crontab貌似只精确到分钟，虽然可以到精确到秒，但是并不满足需求。
选型
公司项目都是 基于 laravel 框架，所以这个没得选。守护进程用的 supervisor，看看这个家伙能不能满足我们的需求
代码
namespace AppConsoleCommands; use IlluminateConsoleCommand; use Cache; use CarbonCarbon; class TaskCommand extends Command { /** * The name and signature of the console command. * * @var string */ protected $signature = 'ue:task {--id= : 当前编号} {--max= : 最大线程} {--sleep= : 休眠多少毫秒} {--debug= : 是否调试模式} '; /** * The console command description. * * @var string */ protected $description = 'Command description'; /** * Create a new command instance. * * @return void */ public function __construct() { parent::__construct(); } /** * Execute the console command. * * @return mixed */ public function handle() { $this->id = $this->option('id') ?? '00'; $this->max = $this->option('max') ?? 32; $this->sleep = $this->option('sleep') ?? 700; $this->debug = $this->option('debug') ?? false; if ($this->id > $this->max) { return true; } while (true) { $this->doRun(); } } /** * * @param int $taskId * @return boolean */ protected function doRun() { $lock = sprintf('task:%03d:%s', $this->id, time()); $data = [ 'id' => $this->id, 'max' => $this->max, 'time' => (new Carbon)->format('Y-m-d H:i:s.u'), 'key' => $lock, ]; try { $result = cache()->get($lock); if ($result) { $data['message'] = 'Task Has been executed.'; $this->wait($this->sleep); return true; } cache()->put($lock, true, 2); $data['message'] = 'Task Executed.'; $this->logger($data); $this->wait($this->sleep); } catch (Exception $ex) { $data['message'] = $ex->getMessage(); cache()->put($data, true, 2); $this->wait($this->sleep); } } /** * 毫秒 * @param string $time */ protected function wait($time) { $wait = $time * 1000; usleep($wait); } protected function logger($message) { if($this->debug){ $time = (new Carbon)->format('Y-m-d H:i:s.u'); $this->line(array_get($message, 'message') .' - '. $time); } logger()->stack(['task'])->debug(null, $message); } }
进程守护
[program:task-worker] process_name=%(program_name)s_%(process_num)02d command=/usr/bin/php /home/wwwroot/demo/artisan ue:task --id=%(process_num)02d --max=8 autostart=true autorestart=true user=www numprocs=8 redirect_stderr=true stdout_logfile=/home/wwwroot/demo/storage/logs/worker.log
上面是supervisor的配置
效果图
