on my local machine I execute the following:
exec('sudo nohup '.PHP_BINDIR.'/php '.ROOT.'/index.php controller=imports action=import id=12 > /dev/null 2>&1 &');
where "ROOT" is a constant with the complete path.
Everything works fine and the script is executed asyncronously with no problems.
When I run the same script on production environment (a bitnami LAMP stack running on AWS) instead: if I run it directly from the terminal it works, when I run it from php it doesn't.
I have nothing in the apache error_log and if I run it with shell_exec the returned value is NULL.
If I try to execute a different script from php (like exec('whoami')) it works, so I don't think is a permissions thing.
I also tried replacing php command with php-cli, nothing changes.
Hope someone can help.
Thanks in advance.
