如何禁用 Laravel 5 日志文件？

Question

My Laravel 5 website is working in a shared host with 1 GB disk space. But now I have about 100 MB log file. How I can disable log file in Laravel 5 ?

Answer 1

In order to completely disable logging you'll need to overwrite the default log handlers that are set by Laravel. You can easily do this with

$nullLogger = new NullHandler();
\Log::getMonolog()->setHandlers(array($nullLogger));

You need to call as early as possible, before request is processed, eg you could do that in your bootstrap/app.php :

$app->configureMonologUsing(function($monolog) {
  $nullLogger = new \Monolog\Handler\NullHandler();
  $monolog->setHandlers(array($nullLogger));
});

return $app;

Answer 2

If your log is very large then either you are logging a lot or your application is throwing a lot of errors. You should first examine the log and see if you can reduce data being written.

You can also switch to daily logging and then have a job to delete old log files.

The next thing to do would be to update your logging configuration to daily instead of the default single in config/app.php

Laravel will handle rotating the file daily and deleting old log files after 5 days, or the value of the app.max_log_files if you need more kept.

Answer 3

I know that this a bit old, but:

In config/logging.php: In channels section add these:

'none' => [
    'driver' => 'monolog',
    'handler' => \Monolog\Handler\NullHandler::class,
],

Then update your.env file to use this logger:

LOG_CHANNEL=none

And everything should work just fine.

Answer 4

Maximum Daily Log Files

When using the daily log mode, Laravel will only retain five days of log files by default. If you want to adjust the number of retained files, you may add a log_max_files configuration value to your app configuration file:

config >> app.php

'log_max_files' => 30

Answer 5

for me, the folder 'tmp' in wamp was growing up 15 giga,! after some research I found out that the reason was the xdebug extension I simply adjut it not to send debug info, from php.ini :

xdebug.profiler_enable = 0

Answer 6

You May disable the writing action Log:: is called by commenting the follow line:

Log::useFiles(storage_path().'/logs/laravel.log');

in start/global.php

But first, you should find out why your log file is that big? Second, having some kind of archive function to your file will help as well. Maybe twice a day.

Hope it helps. Good Luck!

Answer 7

Yes definitively you need to edit core laravel file in order not to save log file..

go to vendor->laravel->framework->src->Illuminate->Log->Writer.php and then comment out all the code within function __call like below.

public function __call($method, $parameters)
{
    // if (in_array($method, $this->levels))
    // {
    //  call_user_func_array(array($this, 'fireLogEvent'), array_merge(array($method), $parameters));

    //  $method = 'add'.ucfirst($method);

    //  return $this->callMonolog($method, $parameters);
    // }

    // throw new \BadMethodCallException("Method [$method] does not exist.");
}

You log will never be save.
