There is no difference in the installer for Xeams Community and Enterprise Edition. It will run as if you have purchased the Enterprise Edition for the first 30 days. It will then get converted to Community Edition unless a license is purchased.
On CentOS 7 SeLinux is more strict than ever before. I had to add configurations to clamd itself to limit the TCP ports it would use and to Selinux to allow those ports. Once I had all that right clamd scanning is working for me.
