1.修改Nova配置文件config/nova.php

//guard修改为admin
'guard' => env('NOVA_GUARD', 'admin'),

Nova配置文件config/nova.php路径和名字也可以改了

//后台名称
'name' => 'Nova Site',

//后台路径，访问改为http://xxx.xxx.xxx/admin
'path' => '/admin',

2.添加guard守护，config/auth.php的guards和providers添加如下

'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'admin' => [
            'driver' => 'session',
            'provider' => 'admins',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
        ],
    ],

//
'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\User::class,
        ],

        'admins' => [
            'driver' => 'eloquent',
            'model' => App\Model\Admin::class,
        ],

        // 'users' => [
        //     'driver' => 'database',
        //     'table' => 'users',
        // ],
    ],

3.修改app/Model/admin.php

<?php

namespace App\Model;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Admin extends Authenticatable
{
    use Notifiable;
    //
}

4.新建Admin-resource 资源**

  php artisan nova:resource Admin

修改app/Nova/Admin.php

<?php

namespace App\Nova;

use Laravel\Nova\Fields\ID;
use Laravel\Nova\Fields\Text;
use Laravel\Nova\Fields\Password;
use Illuminate\Http\Request;

class Admin extends Resource
{
    /**
     * The model the resource corresponds to.
     *
     * @var string
     */
    public static $model = 'App\\Model\\Admin';

    /**
     * The single value that should be used to represent the resource when being displayed.
     *
     * @var string
     */
    public static $title = 'name';

    /**
     * The columns that should be searched.
     *
     * @var array
     */
    public static $search = [
        'id', 'name', 'nickname',
    ];

    /**
     * Get the fields displayed by the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function fields(Request $request)
    {
        return [
            ID::make()->sortable(),

            Text::make('昵称','nickname')
                ->sortable()
                ->rules('required', 'max:255'),

            Text::make('账号','name')
                ->sortable()
                ->rules('required', 'max:255'),

            Password::make('Password')
                ->onlyOnForms()
                ->creationRules('required', 'string', 'min:6')
                ->updateRules('nullable', 'string', 'min:6'),
        ];
    }

    /**
     * Get the cards available for the request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function cards(Request $request)
    {
        return [];
    }

    /**
     * Get the filters available for the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function filters(Request $request)
    {
        return [];
    }

    /**
     * Get the lenses available for the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function lenses(Request $request)
    {
        return [];
    }

    /**
     * Get the actions available for the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function actions(Request $request)
    {
        return [];
    }
}

如果admins表没有创建email字段，搜索应取消email字段，否则搜索报错

fields可以调整一下，avatar和email不用了，有nickname可以加进去

资源本地化，添加一个label方法

    public static function label()
    {
        return __('管理员');
    }

现在Nova后台可以直接使用admin表登录，这样与User用户分开使用

基本本地化使用差不多了。。。
