Description of problem:
SELinux is preventing php-fpm from 'name_connect' accesses on the tcp_socket port 3306.

*****  Plugin catchall_boolean (47.5 confidence) suggests   ******************

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

If you want to allow httpd to can network connect db
Then you must tell SELinux about this by enabling the 'httpd_can_network_connect_db' boolean.

If you believe that php-fpm should be allowed name_connect access on the port 3306 tcp_socket 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
