我使用命令 php artisan schedule:run 运行这些 schulders，并且我正在并行运行许多实例。我的日志文件说 schulder 2 正在第二次启动，即使它的前一个实例还没有完成它。

Just name your task with a call to name()and chain the methods that define when your task should be run.
只需通过调用name()命名您的任务，并链接定义您的任务何时运行的方法。
$schedule->call(function () {
//Some Code
})->everyFiveMinutes()
->name('some_name')
->withoutOverlapping();
For anonymous functions the name is required to prevent overlapping.
对于匿名函数，需要名称以防止重叠。
