在Laravel 5.4上使用php artisan make:auth迁移错误

对我来说很有魅力!

将此添加到config/database.php

'engine' => 'InnoDB ROW_FORMAT=DYNAMIC',

而不是

'engine' => 'null',

如果您运行“php artisan migrate”时出现此错误。你可以这样修改你想要更新的表:

    DB::statement('ALTER TABLE table_name ROW_FORMAT = DYNAMIC;');        

在迁移脚本中。例子:

class MyMigration extends Migration {

/**
 * Run the migrations.
 */
public function up()
{
    DB::statement('ALTER TABLE table_name ROW_FORMAT = DYNAMIC;');        
    Schema::table('table_name', function ($table) {
        //....
    });
}

/**
 * Undo the migrations.
 */
public function down()
{
    //....
}
}

然后再次运行php artisan migrate

1-进入/config/database.php,找到这些行

'mysql' => [
    ...,
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    ...,
    'engine' => null,
 ]

并更改为:

'mysql' => [
    ...,
    'charset' => 'utf8',
    'collation' => 'utf8_unicode_ci',
    ...,
    'engine' => 'InnoDB',
 ]

2-运行php artisan config:cache重新配置laravel

3-删除数据库中现有的表,然后再次运行php artisan migrate

与其设置长度限制,我建议以下方法,这对我来说很有效。

内部:

配置/ database.php

将这一行替换为mysql:

'engine' => 'InnoDB ROW_FORMAT=DYNAMIC',

:

'engine' => null,

对于不想更改AppServiceProvider.php的人。 (在我看来,仅仅为了迁移而更改AppServiceProvider.php是一个坏主意)

您可以将数据长度添加回database/migrations/下的迁移文件,如下所示:

create_users_table.php

$table->string('name',64);
$table->string('email',128)->unique();

create_password_resets_table.php

$table->string('email',128)->index();

只要在/etc/mysql/mariadb.conf.d/50-server.cnf或其他配置文件中写几行:

innodb-file-format=barracuda
innodb-file-per-table=ON
innodb-large-prefix=ON
innodb_default_row_format = 'DYNAMIC'

和sudo服务mysql重启
