WHMCS permission issues: php-fpm and chmod 755

[StevenBork]

Hey guys

I'm having some strange permission issues using PHP-FPM and WHMCS on a CentOS 6.x 64 bit server.

In particular, I got this message:
 

Code:

Permissions Error
The templates compiling directory '/var/www/mysite.com/templates_c' must be writeable (CHMOD 777) before you can continue.
If the path shown is incorrect, you can update it in the configuration.php file.

The only way I can get rid of this issues is chmod 777 to /var/www/mysite.com/templates_c
But, that's insecure, we all know that, right?

The strange thing is:

I'm running PHP-FPM, with their own user, so... 777 shouldn't be necessary, only 755 should be enough. See my current php-fpm configuration for this site:
 

Code:

[mysite.com]

listen = 127.0.0.1:9010
listen.allowed_clients = 127.0.0.1

listen.owner = nginx
listen.group = nginx
listen.mode = 0666

user = mysiteuser33
group = mysiteuser33

pm = dynamic
pm.max_children = 80
pm.start_servers = 15
pm.min_spare_servers = 15
pm.max_spare_servers = 35


request_terminate_timeout = 600
php_admin_value[error_log] = /var/log/php-fpm/error.log
php_admin_value[session.save_path] = /tmp
php_admin_flag[log_errors] = on
php_admin_value[open_basedir] = /var/lib/php/session:/tmp:/var/www/mysite.com:/var/www/updater_tmp_dir/
php_admin_value[memory_limit] = 128M

 

Code:

[root@server.mysite.com:~]finger mysiteuser33
Login: mysiteuser33    			Name: 
Directory: /var/www/       	Shell: /bin/bash
Never logged in.
No mail.
No Plan.

Any ideas?

Appreciate your help.

Thanks

The templates_c folder must be writable by the webserver, same with attachments and downloads. We recommend moving all writeable directories to a non-public location above your web root to prevent web based access and enhancing security.

Please have a look at our documentation here regarding further securing WHMCS: https://docs.whmcs.com/Further_Security_Steps

Please also note the WHMCS Requirements when installing WHMCS does list out the required folder permissions: https://docs.whmcs.com/Installing_WHMCS#Installing_WHMCS
