Laravel 5通过AWS EC2上的cron进行计划 - 命令未运行

Question

Problem:
I have a Laravel 5.4 artisan task that I need to run via cron - but it is not being completed despite the Command and Scheduler being (apparently) set-up correctly.

Is this a Laravel, php, apache, linux or crontab issue ? What's the best way to diagnose ?

Background
On default (amazon AMI) EC2 instance, the artisan command is defined correctly and runs perfectly from the project directory (which is /var/www/html/myproject/ ) when called via:

php artisan mycommand:option1

I've added this to a schedule into app/Console/Kernel.php which looks like this:

protected function schedule(Schedule $schedule)
{
    Log::info('schedule:run');
    $schedule   ->command('mycommand:option1')
                        ->dailyAt('07:00')
                        ->emailOutputTo('email@email.com');

    $schedule   ->command('mycommand:option2')
                        ->dailyAt('07:15')
                        ->emailOutputTo('email@email.com');
}

Added the following cron command for apache via sudo crontab -u apache -e :

* * * * * php /var/www/html/myproject/artisan schedule:run >> /dev/null 2>&1

To ensure it's not a permissions issue I also added the same command for the following users :

• ec2-user via crontab -e
• root via sudo crontab -e

Answer 1

the issue was related to php missing its (absolute) path in the cron command definition

the cron command should have been:

* * * * * /usr/local/bin/php /var/www/html/myproject/artisan schedule:run >> /dev/null 2>&1

you can get the correct php path from the output of which php in terminal

Notes:
- Laravel Scheduler commands work fine from apache user by adding cron commands via:

sudo crontab -u apache -e  

- Laravel still not logging the Log::info('schedule:run'); each minute like it should... even when running cron commands from root (ie setting cron via sudo crontab -e )
This is probably related to some other setting in Laravel - as it doesn't log anything even when Scheduler is run manually via php artisan schedule:run from project root

Answer 2

Typically, a rule of thumb would be to check write permissions on your log file to ensure it is write-able by the apache user.

If all else fails you can explicitly point to your log file in the crontab:

* * * * * /usr/local/bin/php /var/www/html/myproject/artisan schedule:run >> /var/www/html/myproject/storage/logs/laravel.log 2>&1

If your jobs needs access to resources such as the DB, then you may want to source an environment variables definition file before calling artisan. Something like so:

* * * * * source /path/to/envvars; /usr/local/bin/php /var/www/html/myproject/artisan schedule:run >> /var/www/html/myproject/storage/logs/laravel.log 2>&1

Good luck.
