## 一.创建表 ##

1.执行命令：sudo php artisan make:migration create\_tableName\_table  
执行完后会在 migrations 文件夹下面生成一个文件

        public function up()

            Schema::create('operation_center_admin', function (Blueprint $table) { 
                $table->increments('id')->comment("主索引");

                $table->string("ip");
                $table->timestamp('created_at')->default(DB::raw('CURRENT_TIMESTAMP'));
                $table->timestamp('updated_at')->default(DB::raw('CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP'));
            });
        }
    
        /** * Reverse the migrations. * * @return void */
        public function down()
        { 
            Schema::dropIfExists('operation_center_admin');

Schema::create('operation_center_permission', function (Blueprint $table) { 
                $table->increments('id')->comment("主索引");
                $table->string('module',50)->comment("模块");

                $table->timestamp('updated_at')->default(DB::raw('CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP'));
            });

## 二.表里添加字段 ##

1.执行命令：php artisan make:migration alter\_表名\_table --table=表名

2.在 up 方法中添加或者修改你需要的字段

3.执行命令： php artisan migrate

在laravel迁移中，我们一般知道把一个字段设置为空，可以通过

$table->column->nullable();

那么，把一个空字段改成非空字段呢，

$table->column->nullable(false);
