SELinux is preventing /usr/sbin/httpd from 'read' accesses on the lnk_file /var/lib/mysql.

*****  Plugin catchall (100. confidence) suggests  ***************************

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