After the recent repo problem resolution I removed the Gluu repo and reinstalled it. I then installed gluu server with yum on the Centos 7 server. I could not start the Gluu Server to run the install script. perhaps new instructions need to be posted on how to use systemctl. Also, at about 1:55 I say that I think the "yum install wget" command worked. It did not. I was testing yum at the time which was not working because of a (local) repo problem and all yum install requests were not working at that time. They began working after I removed and reinstalled the Gluu repo.
