"Backup Now" fail as fopen got permission denied

[yywudi]

after add backup jobs, run as root manually with command is OK, but click the Backup Now in the job, always fail, seems permission issue when create backup .tar.gz file under files folder. I've already chmod 777 files, and chown -R www-data:www-data to the cdp folder, also enable the fopen in php.ini as below. allow_url_fopen = On allow_url_include = On

but always failed, any suggestion how to configure the permission?

Backup task is running in the background Warning: fopen(cdpme-2014-11-12-06-47-20-4bfbb1c2f*****f5f61fb5a.tar.gz): failed to open stream: Permission denied in /var/www/****/public/cdp/phpseclib/Net/SFTP.php on line 2026

View Backups will show all the failed backup job with filesize NANb, and can't delete those content as "file not exist"

I pushed an update for index.php, please try it and let me know if the error still occurs. If so, please make sure php/apache get enough permission to run cron.php using shell_exec().

[yywudi]

update the index.php, and re-test.
still no backup file created, add one more backup log with NANb file size. I'm not sure if enable shell_exec() permission correctly, i'm using nginx & php-fpm. but there's no error just "Backup task has been started, please do not close this window".

besides, is that safe to run shell_exec() for php?

[PetaByet]

Please add echo to line 149, like echo shell_exec('php '.$config['path'].'/cron.php '.$_REQUEST['id']); so you can see the output.

[yywudi]

yep the echo for shell_exec got the same error as before: Warning: fopen(cdpme-2014-11-12-07-47-25-ac8a***_a3e6ba16.tar.gz): failed to open stream: Permission denied in /var/www/_*/public/cdp/phpseclib/Net/SFTP.php on line 2026

You can probably use sudo and grant the apache user root permissions.

Dont ever do that, pleaseeeeee! never ever EVER give a website escalated privileges. It will be pretty much equal to bending over in a prison shower, waiting to get raped

The solution to this is: chown -R apache:apache /var/www/html/
