I would like to know if it is possible to install ClearOS 7 from a CentOS installation.
My service provider does not allow the ISO to be uploaded and I only have the option of installing CentOS 7.
Any suggestions?

Sorry for the delay, but notification e-mails of new posts have been failing so yours got stuck under moderation.
Yes it is possible but I don't know how. There is a Linode Stackscript here which may work. It may need adjusting for the eth0 interface if the Centos installation uses a different interface. I'd try using whatever Centos uses. If you can get to a console or the webconfig afterwards, that part of the installation can be adjusted. I'll ask Dave as he knows more about it.
[edit]
If it works, please then do a:
To bring your system up to date. After that automatic updates should work. They may work anyway.yum update app-base
yum clean all
yum update

Here is a modified setup based on the Linode information Nick was talking about. You will need to start with a sparse install of CentOS available. For virtualization providers, find a very minimal instance type to use.
sudo su -
yum -y remove NetworkManager
# Set SELinux to disabled
/etc/selinux/config
reboot
ClearOS Home and Business
It can be difficult to get business installed on a CentOS system that comes via a virtual platform like AWS because many of them run updates which will give you a very advanced version and depending on the update cycle, you may not be able to update unless you enable repos. When stuck, find the equivalent step in ClearOS community and run yum with --enablerepo=clearos-updates,clearos-centos.

rpm -ivh --nodeps app-base-*
yum --enablerepo=* clean all
rpm -ivh --nodeps system-base-*.rpm
yum install clearos-release-*.rpm
yum reinstall app-base-*
yum --enablerepo=* clean all
yum reinstall system-base
yum reinstall clearos-release
yum --enablerepo=* clean all
rm -f *.rpm
systemctl stop webconfig
In clearos-centos.repo modify the enabled value:
- only works if your minimal installation has yum-config-manager. If not you have to do a manual edit:yum-config-manager enable clearos-centos
If you don't get on with vi, try with the editor "nano" which may be installed.vi /etc/yum.repos.d/clearos-centos.repo
Set a root password so that you can login to Webconfig
passwd
Run updates to basics and fixup nameserver then finish updates
yum --enablerepo=* clean all && yum -y update app-base
yum --enablerepo=* clean all && yum -y update
yum --enablerepo=* clean all
echo "nameserver 8.8.8.8" > /etc/resolv.conf
yum -y install app-accounts app-configuration-backup app-dashboard app-date app-dns app-edition app-events app-incoming-firewall app-groups app-language app-log-viewer app-mail app-marketplace app-process-viewer app-software-updates app-ssh-server app-support app-user-profile app-users
systemctl restart syswatch
