although wasteful, this command should fix it:
cd /;rm -rf /opt/svn;mkdir /opt/svn;cd /opt/svn;setenforce 0;systemctl restart firewalld;for service in http https tftp ftp mysql nfs mountd rpc-bind proxy-dhcp samba; do firewall-cmd --permanent --zone=public --add-service=$service; done;systemctl restart firewalld.service;systemctl enable firewalld;yum install svn -y;svn co https://svn.code.sf.net/p/freeghost/code/trunk;cd trunk/bin;./installfog.shAlso - you can permanently disable SELinux by editing the /etc/selinux/config file.
