Kloxo-MR is an open source server control panel that can be used to create and manage virtual hosts on Redhat/CentOS 5, 6 and 7 systems. As can be seen from the name, Kloxo-MR is improved based on Kloxo, but Kloxo-MR has poor performance. A lot of improvements have been made to it as well as its functions, making it easier to use.
