1、 先去`web.php`文件中配置路由组：

Route::prefix('admin')->group(function () {
       Route::get('/', 'Admin\DashboardController@index');
    });

2、生成后台首页控制器：php artisan make:controller Admin/DashboardController并创建index方法,里面直接打印管理员session，如：

public function index()
    {
        dd('后台首页，当前管理员：' . auth('admin')->user()->name);
    }
    3、创建管理员(admins)数据表
    (1) 生成admins表的迁移文件：php artisan make:migration create_admins_table,
    (2) 修改 database/migrations/*_create_admins_table.php 中的 up()方法,如：
    
    public function up()
    {
        Schema::create('admins', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }

终端执行php artisan migrate, 手动往数据表admins里面添加一条数据。  
(3) 生成数据表模型：php artisan make:model Models/Admin,并修改app/Models/Admin.php为：

<?php
    namespace App\Models;
    use Illuminate\Notifications\Notifiable;
    use Illuminate\Foundation\Auth\User as Authenticatable;
    class Admin extends Authenticatable
    {
        use Notifiable;
    
        /**
         * The attributes that are mass assignable.
         *
         * @var array
         */
        protected $fillable = [
            'name', 'email', 'password',
        ];
    
        /**
         * The attributes that should be hidden for arrays.
         *
         * @var array
         */
        protected $hidden = [
            'password', 'remember_token',
        ];
    }

(4) 修改路由组,如下：

Route::prefix('admin')->namespace('Admin')->group(function () {
        $this->get('login', 'LoginController@showLoginForm')->name('admin.login');
        $this->post('login', 'LoginController@login');
        $this->post('logout', 'LoginController@logout')->name('admin.logout');
        Route::name('admin.')->group(function () {
            $this->get('/', 'DashboardController@index');
        });
    });

(5) 新建管理员登录控制器：php artisan make:controller Admin/LoginController,添加代码如下：

<?php
    
    namespace App\Http\Controllers\Admin;
    
    use App\Http\Controllers\Controller;
    use Illuminate\Foundation\Auth\AuthenticatesUsers;
    use Illuminate\Http\Request;
    
    class LoginController extends Controller
    {
        use AuthenticatesUsers;
    
        protected $redirectTo = '/admin';
    
        public function __construct()
        {
            $this->middleware('guest:admin')->except('logout');
        }
    
        public function username()
        {
            return 'name';
        }
    
        public function attemptLogin(Request $request)
        {
            $username = $request->input('name');
            $password = $request->input('password');
    
            // 验证用户名登录方式
            $usernameLogin = $this->guard()->attempt(
                ['name' => $username, 'password' => $password], $request->has('remember')
            );
            if ($usernameLogin) {
                return true;
            }
    
            // 验证手机号登录方式
            $mobileLogin = $this->guard()->attempt(
                ['tel' => $username, 'password' => $password], $request->has('remember')
            );
            if ($mobileLogin) {
                return true;
            }
    
            // 验证邮箱登录方式
            $emailLogin = $this->guard()->attempt(
                ['email' => $username, 'password' => $password], $request->has('remember')
            );
            if ($emailLogin) {
                return true;
            }
    
            return false;
        }
        /**
     * 加入验证码验证
     * Validate the user login request.
     *
     * @param  \Illuminate\Http\Request $request
     * @return void
     *
     * @throws \Illuminate\Validation\ValidationException
     */
    protected function validateLogin(Request $request)
    {
        $request->validate([
            'captcha' => 'required|captcha',
            $this->username() => 'required|string',
            'password' => 'required|string',
        ]);
    }
    
        public function showLoginForm()
        {
            return view('admin.auth.login');
        }
    
        protected function guard()
        {
            return auth()->guard('admin');
        }
    
        /**
         * 后台管理员退出跳转到后台登录页面
         * Log the user out of the application.
         *
         * @param  \Illuminate\Http\Request  $request
         * @return \Illuminate\Http\Response
         */
        public function logout(Request $request)
        {
            $this->guard()->logout();
    
            $request->session()->invalidate();
    
            return redirect('/admin/login');
        }
    
    }

(6) 添加管理员认证，修改config/auth.php文件，如：

'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\Models\Admin::class,
        ]
    // 'users' => [
    //     'driver' => 'database',
    //     'table' => 'users',
    // ],
    ],

(7) 新建登录模板 resources/views/admin/auth/login.blade.php ，我这里使用amazeui自带的登录模板，使用之前必须引入amazeui的样式。注意：修改登录提交的路由地址\{ \{ route(‘admin.login’) \}\}。  
通过命令：php artisan make:middleware AdminAuthMiddleware创建后台管理员中间件，并添加代码如下：

<?php
    namespace App\Http\Middleware;
    use Closure;
    use Illuminate\Support\Facades\Auth;
    class AdminAuthMiddleware
    {
        public function handle($request, Closure $next, $guard = null)
        {
        //当 auth 中间件判定某个用户未认证，会返回一个 JSON 401 响应，或者，如果不是 Ajax 请求的话，将用户重定向到 login 命名路由（也就是登录页面）。
            if (Auth::guard($guard)->guest()) {
                if ($request->ajax() || $request->wantsJson()) {
                    return response('Unauthorized.', 401);
                } else {
                    return redirect()->guest('admin/login');
                }
            }
            return $next($request);
        }
    }

接下来去app\\Http\\Kernel.php里面注册该中间件 ‘auth.admin’ => \\App\\Http\\Middleware\\AdminAuthMiddleware::class, ，并在web.php中使用此中间件，  
此时的路由如下：

Route::prefix('admin')->namespace('Admin')->group(function () {
        $this->get('login', 'LoginController@showLoginForm')->name('admin.login');
        $this->post('login', 'LoginController@login');
        $this->post('logout', 'LoginController@logout')->name('admin.logout');
        Route::middleware('auth.admin:admin')->name('admin.')->group(function () {
            $this->get('/', 'DashboardController@index');
        });
    });

登录就能进到后台首页了
