Description of problem:
SELinux is preventing php-fpm from 'create' accesses on the directory scheme.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If you want to allow httpd to unified
Then you must tell SELinux about this by enabling the 'httpd_unified' boolean.
You can read 'None' man page for more details.
Do
setsebool -P httpd_unified 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that php-fpm should be allowed create access on the scheme directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep php-fpm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
