Description of problem:
Periodically after installation of Fedora 21, alerted via SELinux Alert Browser / Troubleshooter
SELinux is preventing /usr/libexec/mysqld from 'name_connect' accesses on the tcp_socket port 443.

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

If you want to allow system to run with NIS
Then you must tell SELinux about this by enabling the 'nis_enabled' boolean.
You can read 'None' man page for more details.
Do
setsebool -P nis_enabled 1

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

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

*****  Plugin catchall (6.38 confidence) suggests   **************************

If you believe that mysqld should be allowed name_connect access on the port 443 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 mysqld /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
