This is my migration file code

Schema::create('hierarchies', function (Blueprint $table) {

    $table->integer('id');

    $table->integer('hierarchy_id');

    $table->timestamps();

});

I want my ID column will be auto increment without primary and hierarchy_id will be my primary key.
How to do that?

My Answer:
increments('id');
$table->string('name');
$table->integer('parent_id')->unsigned()->nullable();
$table->integer('order')->unsigned()->autoIncrement();
});
