This article mainly introduces how to modify the default log file name and location in Laravel. It has certain reference value. Now I share it with you. Friends in need can refer to it

Modify the default log location

In our usual development, we may always put laravel's log files in the default location without any impact, but if our project is fully deployed when it goes online, and each deployment is the latest code in git, then at this time Our logs will be cleared every time, showing that this is not what we expected. Fortunately, laravel provides us with a way to modify it.

Here we take the example of placing it in /var/log/nginx/app/phphub/phphub.log

Add log processing class

#First we create a new file, app /Foundation/Bootstrap/ConfigureLogging.php, the code is as follows:

<?php
namespace App\Foundation\Bootstrap;
use Illuminate\Log\Writer;
use Illuminate\Contracts\Foundation\Application;
class ConfigureLogging
{
 /**
 * 设置应用的Monolog处理程序
 *
 * @param \Illuminate\Contracts\Foundation\Application $app
 * @param \Illuminate\Log\Writer $log
 * @return void
 */
 public function configureHandlers(Application $app, Writer $log)
 {
 $method = &#39;configure&#39;.ucfirst($app[&#39;config&#39;][&#39;app.log&#39;]).&#39;Handler&#39;;
 $this->{$method}($app, $log);
 }
 /**
 * 设置应用single模式下的Monolog处理程序
 *
 * @param \Illuminate\Contracts\Foundation\Application $app
 * @param \Illuminate\Log\Writer $log
 * @return void
 */
 protected function configureSingleHandler(Application $app, Writer $log)
 {
 $config = $app->make(&#39;config&#39;);
 $filename = $config->get(&#39;app.log_path&#39;, &#39;/var/log/nginx/app/system&#39;) . &#39;/&#39; . $config->get(&#39;app.log_name&#39;, &#39;laravel&#39;) . &#39;.log&#39;;
 $log->useFiles($filename);
 }
 /**
 * 设置应用daily模式下的Monolog处理程序
 *
 * @param \Illuminate\Contracts\Foundation\Application $app
 * @param \Illuminate\Log\Writer $log
 * @return void
 */
 protected function configureDailyHandler(Application $app, Writer $log)
 {
 $config = $app->make(&#39;config&#39;);
 $filename = $config->get(&#39;app.log_path&#39;, &#39;/var/log/nginx/app/system&#39;) . &#39;/&#39; . $config->get(&#39;app.log_name&#39;, &#39;laravel&#39;) . &#39;.log&#39;;
 $log->useDailyFiles(
 $filename,
 $app->make(&#39;config&#39;)->get(&#39;app.log_max_files&#39;, 5)
 );
 }
 /**
 * 设置应用syslog模式下的Monolog处理程序
 *
 * @param \Illuminate\Contracts\Foundation\Application $app
 * @param \Illuminate\Log\Writer $log
 * @return void
 */
 protected function configureSyslogHandler(Application $app, Writer $log)
 {
 $log->useSyslog($app->make(&#39;config&#39;)->get(&#39;app.log_name&#39;, &#39;laravel&#39;));
 }
 /**
 * 设置应用errorlog模式下的Monolog处理程序
 *
 * @param \Illuminate\Contracts\Foundation\Application $app
 * @param \Illuminate\Log\Writer $log
 * @return void
 */
 protected function configureErrorlogHandler(Application $app, Writer $log)
 {
 $log->useErrorLog();
 }
}

 */
&#39;log_path&#39; => &#39;/var/log/nginx/app/&#39; . env(&#39;APP_NAME&#39;, &#39;laravel&#39;),
/**
 * 日志文件名称
 */
&#39;log_name&#39; => env(&#39;APP_NAME&#39;, &#39;laravel&#39;),
/**
 * 日志文件最大数
 */
&#39;log_max_files&#39; => &#39;30&#39;,

Copy after login

to php and apply our new processing class

#Modify Bootstrap/app.php and add code before return $app

$app->configureMonologUsing(function($monolog) use ($app) {
 $configureLogging = new App\Foundation\Bootstrap\ConfigureLogging();
 $configureLogging->configureHandlers($app, $app->log);
});

At this time we You can use \Log::info('test log info'); to test it, and the log should be recorded in /var/log/nginx/app/phphub/phphub.logbingo.
