修改 bootstrap/app.php 文件
$app->configureMonologUsing(function($monolog) use ($app) {
$monolog->pushHandler(
(new Monolog\Handler\RotatingFileHandler(
'/var/logs/app/laravel',
$app->make('config')->get('app.log_max_files', 5)
))->setFormatter(new Monolog\Formatter\LineFormatter(null, null, true, true))
);
});
添加以后写入日志文件为：
-rw-r--r-- 1 web web 93 Dec 18 15:52 laravel-2017-12-17 -rw-r--r-- 1 web web 279 Dec 18 16:10 laravel-2017-12-18
参考：Laravel 的错误和日志记录
或者
创建app\Providers\LogServiceProvider.php 文件
修改 config\app.php providers 增加
App\Providers\LogServiceProvider::class
然后 App\Providers\LogServiceProvider.php 内容如下
<?php
namespace App\Providers;
use Illuminate\Log\LogServiceProvider as SysServiceProvider;
use Illuminate\Log\Writer;
class LogServiceProvider extends SysServiceProvider
{
protected function configureSingleHandler(Writer $log)
{
$log->useFiles(
'/var/logs/app/laravel.log',
$this->logLevel()
);
}
protected function configureDailyHandler(Writer $log)
{
$log->useDailyFiles(
'/var/logs/app/laravel.log', $this->maxFiles(),
$this->logLevel()
);
}
}
增加请求ID request id
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Carbon\Carbon;
class LogServiceProvider extends ServiceProvider
{
protected $log_file;
/**
* Bootstrap any application services.
* @return void
*/
public function boot()
{
//
}
/**
* Register any application services.
* @return void
*/
public function register()
{
$this->load_request_id();
$this->log_configure();
}
/**
* 生成 request_id
* @return void
*/
protected function load_request_id()
{
define( 'REQUEST_ID' , config('app.log_prefix').Carbon::now()->timestamp );
}
/**
* 注册 monolog pushHandler
* @return void
*/
protected function log_configure()
{
$log_file = $this->getLogFile();
$log_max_files = $this->getLogMaxFiles();
/**
* @doc https://d.laravel-china.org/docs/5.4/errors#自定义-Monolog-设置
*/
$this->app->configureMonologUsing(function($monolog) use ($log_file , $log_max_files) {
$monolog->pushHandler(
(new \Monolog\Handler\RotatingFileHandler(
$log_file ,
$log_max_files
))->setFormatter(new \Monolog\Formatter\LineFormatter( "[
