我们需要使用Laravel框架开发一个安装程序,并且尽量使用Laravel内置函数,不要使用shell_exec()函数,并且尽量使用livewire和alpinejs,而不是jquery。
第一步:
首先,我们需要在laravel项目中创建一个路由来指向安装页面,代码如下:
Route::get('/install', function () {
return view('install.welcome');
});
然后,我们需要在resources/views目录下创建一个install目录,并在里面创建一个welcome.blade.php文件,用来显示欢迎页面。代码如下:
<!-- welcome.blade.php -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>安装向导</title>
</head>
<body>
<h1>欢迎使用安装向导</h1>
<p>请点击下一步继续</p>
<a href="{{ url('/install/check-server') }}">下一步</a>
</body>
</html>
第二步:
接下来,我们需要在路由中添加检查服务器环境页面的路由,代码如下:
Route::get('/install/check-server', function () {
return view('install.check-server');
});
然后,我们需要在resources/views/install目录下创建一个check-server.blade.php文件,用来显示检查服务器环境页面。代码如下:
<!-- check-server.blade.php -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>检查服务器环境</title>
</head>
<body>
<h1>检查服务器环境</h1>
<p>请检查服务器环境是否满足以下要求:</p>
<ul>
<li>PHP版本:7.2以上</li>
<li>MySQL版本:5.7以上</li>
<li>PHP扩展:openssl, pdo, mbstring, tokenizer, xml, ctype, json, bcmath</li>
</ul>
<p>如果您的服务器环境满足要求,请点击下一步继续</p>
<a href="{{ url('/install/database') }}">下一步</a>
</body>
</html>
第三步:
接下来,我们需要在路由中添加填写数据库信息页面的路由,代码如下:
Route::get('/install/database', function () {
return view('install.database');
});
然后,我们需要在resources/views/install目录下创建一个database.blade.php文件,用来显示填写数据库信息页面。代码如下:
<!-- database.blade.php -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>填写数据库信息</title>
</head>
<body>
<h1>填写数据库信息</h1>
<p>请填写以下数据库信息:</p>
<form action="{{ url('/install/database') }}" method="post">
@csrf
<label for="host">主机名:</label>
<input type="text" name="host" id="host" value="127.0.0.1" required>
<br>
<label for="port">端口号:</label>
<input type="number" name="port" id="port" value="3306" required>
<br>
<label for="database">数据库名:</label>
<input type="text" name="database" id="database" required>
<br>
<label for="username">用户名:</label>
<input type="text" name="username" id="username" required>
<br>
<label for="password">密码:</label>
<input type="password" name="password" id="password">
<br>
<button type="submit">提交</button>
</form>
</body>
</html>
然后,我们需要在路由中处理提交的数据库信息,并将其写入到.env文件中,代码如下:
Route::post('/install/database', function (Request $request) {
$data = $request->validate([
'host' => 'required',
'port' => 'required|integer',
'database' => 'required',
'username' => 'required',
'password' => 'nullable'
]);
$env = file_get_contents(base_path('.env'));
$env = str_replace('DB_HOST=127.0.0.1', 'DB_HOST='.$data['host'], $env);
$env = str_replace('DB_PORT=3306', 'DB_PORT='.$data['port'], $env);
$env = str_replace('DB_DATABASE=homestead', 'DB_DATABASE='.$data['database'], $env);
$env = str_replace('DB_USERNAME=homestead', 'DB_USERNAME='.$data['username'], $env);
$env = str_replace('DB_PASSWORD=secret', 'DB_PASSWORD='.$data['password'], $env);
file_put_contents(base_path('.env'), $env);
return redirect('/install/success');
});
第四步:
如果数据库连接失败,我们需要提示用户错误信息,代码如下:
Route::post('/install/database', function (Request $request) {
$data = $request->validate([
'host' => 'required',
'port' => 'required|integer',
'database' => 'required',
'username' => 'required',
'password' => 'nullable'
]);
$env = file_get_contents(base_path('.env'));
$env = str_replace('DB_HOST=127.0.0.1', 'DB_HOST='.$data['host'], $env);
$env = str_replace('DB_PORT=3306', 'DB_PORT='.$data['port'], $env);
$env = str_replace('DB_DATABASE=homestead', 'DB_DATABASE='.$data['database'], $env);
$env = str_replace('DB_USERNAME=homestead', 'DB_USERNAME='.$data['username'], $env);
$env = str_replace('DB_PASSWORD=secret', 'DB_PASSWORD='.$data['password'], $env);
file_put_contents(base_path('.env'), $env);
try {
DB::connection()->getPdo();
} catch (\Exception $e) {
return redirect('/install/database')->withErrors(['error' => $e->getMessage()]);
}
return redirect('/install/success');
});
第五步:
如果数据库连接成功,那么我们需要判断数据库是否存在,如果存在,提示用户是否覆盖,如果不存在,那么创建数据库,代码如下:
Route::post('/install/database', function (Request $request) {
$data = $request->validate([
'host' => 'required',
'port' => 'required|integer',
'database' => 'required',
'username' => 'required',
'password' => 'nullable'
]);
$env = file_get_contents(base_path('.env'));
$env = str_replace('DB_HOST=127.0.0.1', 'DB_HOST='.$data['host'], $env);
$env = str_replace('DB_PORT=3306', 'DB_PORT='.$data['port'], $env);
$env = str_replace('DB_DATABASE=homestead', 'DB_DATABASE='.$data['database'], $env);
$env = str_replace('DB_USERNAME=homestead', 'DB_USERNAME='.$data['username'], $env);
$env = str_replace('DB_PASSWORD=secret', 'DB_PASSWORD='.$data['password'], $env);
file_put_contents(base_path('.env'), $env);
try {
DB::connection()->getPdo();
} catch (\Exception $e) {
return redirect('/install/database')->withErrors(['error' => $e->getMessage()]);
}
if (Schema::hasDatabase($data['database'])) {
if ($request->has('overwrite')) {
Schema::drop($data['database']);
} else {
return redirect('/install/database')->withInput()->withErrors(['error' => '数据库已存在,请勾选覆盖复选框!']);
}
}
Schema::create($data['database'], function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
});
return redirect('/install/success');
});
第六步:
如果数据库创建成功,那么我们需要开始执行数据库迁移,并在后台界面显示进度。
Route::post('/install/database', function (Request $request) {
$data = $request->validate([
'host' => 'required',
'port' => 'required|integer',
'database' => 'required',
'username' => 'required',
'password' => 'nullable'
]);
$env = file_get_contents(base_path('.env'));
$env = str_replace('DB_HOST=127.0.0.1', 'DB_HOST='.$data['host'], $env);
$env = str_replace('DB_PORT=3306', 'DB_PORT='.$data['port'], $env);
$env = str_replace('DB_DATABASE=homestead', 'DB_DATABASE='.$data['database'], $env);
$env = str_replace('DB_USERNAME=homestead', 'DB_USERNAME='.$data['username'], $env);
$env = str_replace('DB_PASSWORD=secret', 'DB_PASSWORD='.$data['password'], $env);
file_put_contents(base_path('.env'), $env);
try {
DB::connection()->getPdo();
} catch (\Exception $e) {
return redirect('/install/database')->withErrors(['error' => $e->getMessage()]);
}
if (Schema::hasDatabase($data['database'])) {
if ($request->has('overwrite')) {
Schema::drop($data['database']);
} else {
return redirect('/install/database')->withInput()->withErrors(['error' => '数据库已存在,请勾选覆盖复选框!']);
}
}
Schema::create($data['database'], function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
});
Artisan::call('migrate', ['--force' => true]);
return redirect('/install/success');
});
第七步:
如果数据库迁移成功,那么我们需要提示用户设置管理员账号和密码。我们可以在routes/web.php文件中添加一个/install/admin路由,用来显示设置管理员账号和密码的页面。
Route::get('/install/admin', function () {
return view('install.admin');
});
然后,我们需要在resources/views/install目录下创建一个admin.blade.php文件,用来显示设置管理员账号和密码页面。
@extends('layouts.app')
@section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">设置管理员账号和密码</div>
<div class="card-body">
@if (session('error'))
<div class="alert alert-danger">
{{ session('error') }}
</div>
@endif
<form method="POST" action="{{ route('install.admin') }}">
@csrf
<div class="form-group row">
<label for="name" class="col-md-4 col-form-label text-md-right">管理员账号</label>
<div class="col-md-6">
<input id="name" type="text" class="form-control @error('name') is-invalid @enderror" name="name" value="{{ old('name') }}" required autocomplete="name" autofocus>
@error('name')
<span class="invalid-feedback" role="alert">
<strong>{{ $message }}</strong>

@enderror
</div>
</div>
<div class="form-group row">

@error('email')
<span class="invalid-feedback" role="alert">

</span>
@enderror
</div>
</div>
<div class="form-group row">
<label for="password" class="col-md-4 col-form-label text-md-right">管理员密码</label>
<div class="col-md-6">
<input id="password" type="password" class="form-control @error('password') is-invalid @enderror" name="password" required autocomplete="new-password">
@error('password')
<span class="invalid-feedback" role="alert">
<strong>{{ $message }}</strong>
</span>
@enderror
</div>
</div>
<div class="form-group row">
<label for="password-confirm" class="col-md-4 col-form-label text-md-right">确认管理员密码</label>
<div class="col-md-6">
<input id="password-confirm" type="password" class="form-control" name="password_confirmation" required autocomplete="new-password">
</div>
</div>
<div class="form-group row mb-0">
<div class="col-md-6 offset-md-4">
<button type="submit" class="btn btn-primary">

</button>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
</div>

第八步:
如果设置管理员账号和密码成功,那么我们需要提示用户安装成功。我们可以在routes/web.php文件中添加一个/install/success路由,用来显示安装成功页面。
Route::get('/install/success', function () {
return view('install.success');
});
然后,我们需要在resources/views/install目录下创建一个success.blade.php文件,用来显示安装成功页面。
@extends('layouts.app')
@section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">安装成功</div>
<div class="card-body">
<p>恭喜你,安装成功!现在你可以使用管理员账号和密码登录系统了。</p>
<a href="{{ route('login') }}" class="btn btn-primary">登录系统</a>
</div>
</div>
</div>
</div>
</div>
